Microcontroller, Reset, and JTAG (Schematic page 1) Page 1 of the schematics details the microcontroller, and JTAG debug interface. Microcontroller At the core of the IDM-L35 is the Stellaris LM3S1958 microcontroller (U1). The Stellaris microcontroller operates at up to 50 MHz using an internal PLL. The LM3S1958 microcontroller has an internal LDO voltage regulator that supplies power for internal use. This rail requires only three capacitors for decoupling and is not connected to any other circuits. A reset switch (SW1) and R-C network (R25, C15) connect to the microcontroller’s RSTn input. An external reset circuit is not required by the LM3S1958 microcontroller, the R-C components simply serve to filter any noise on the reset line. Debugging The microcontroller supports JTAG and SWD debugging as well as SWO trace capabilities. To minimize board area, the IDM-L35 uses a 0.050” pitch header (J6) which matches ARM’s fine-pitch definition (Figure 2-2). Some in-circuit debuggers provide a matching connector. Other debuggers can be used with the ADA1 adaptor board included in the RDK. Figure 2-2. Debug Connection Pinout 1 2 TMS/ SWDIO TCK/ SWCLK TDO TDI SRSTn 3.3V GND GND n/c GND 9 10 LCD Panel and Voltage Regulators (Schematic page 2) Page 2 of the schematics contains the LCD panel connector, 3.3 V DC regulator, and the high voltage LED driver for the LCD panel backlight. LCD Panel The LCD panel is attached to FPC ZIF connector P1 and is a 3.5” TFT panel with an integrated controller (SSD2119). The graphics display memory resides in the LCD panel and contains 168 kilobytes. The LCD panel requires only a 3.3 V power supply which also simplifies system design. The LCD panel system interface has several modes of operation, for the IDM-L35 it is configured for 8080 series 16-bit parallel interface mode for improved data rate. Only two control lines (LCD_RDn, LCD_WRn) are required for reading and writing to the panel. A third signal (LCD_DC) selects between memory and display control register access. In order to meet reset signal timing requirements the microcontroller also controls the panel’s reset signal (LCD_RSTn). 14 September 7, 2010 Stellaris® Intelligent Display Module with 3.5" Display The LCD panel incorporates a white LED backlight with 6 LEDs in series which requires a high power serial driver (U7) for operation. The backlight power driver shutdown input is controlled by microcontroller GPIO pin PH0/CCP6. For full brightness, set PH0 high. For dim control, a 1 kHz PWM signal can be generated with CCP6. For additional LCD panel information, refer to the data sheet on the RDK-IDM-L35 CD and LCD driver source code in the Stellaris graphics library. Touch Panel Four ADC channels and four GPIO lines connect directly to the resistive touch panel, allowing the microcontroller to manage all aspects of operation. X and Y axis position measurements are made independently. For X-axis measurement, GPIO pins PC4 and PC5 are set HIGH and LOW respectively to form a resistor divider between 3 V and 0 V. The voltage on ADC4 and ADC5 indicates the X-axis position. To measure the Y-axis position, PD2 and PD3 are set HIGH and LOW respectively and the voltage on ADC6 or ADC7 is measured. Software controls calibration and finger press detection functions. High Power LED Driver The LCD panel backlight has 6 LEDs in series and requires a high power LED driver (U7) for operation, providing 20 mA at 20 V. The LCD_BL signal driven from a microcontroller GPIO is used to turn the backlight on and off. A 1 kHZ PWM signal can be used instead for dim control. 3.3 V DC Regulator The IDM-L35 operates with 5 V DC, which can be applied via DC jack J7, terminal block J1, or header J8. The RDK includes a USB to TTL serial cable that connects to J8 and receives 5 V from the USB port. DC regulator U3 generates 3.3 V for powering the board circuits and includes power indicator LED D1. UART, microSD Card Slot, Speaker, Analog Inputs, Digital I/O (Schematic page 3) The third schematic page contains the UART RS-232 transceiver, microSD card slot, speaker, terminal blocks, and headers. RS232 Serial Port The MAX3221 (U2) line transceiver interfaces between UART2 and the RS232 port pins on J3. UART2 uses ports PG0 and PG1. microSD Card Slot Standard microSD media may be used for image or data storage. The SD card is wired for use in SPI mode, rather than the 1-bit or 4-bit SD modes. Speaker Speaker SPK1 is a small magnetic audio transducer which is driven by PC7/CCP4 through a small transistor. CCP4 can be configured to generate a free-running tone at the required frequency. September 7, 2010 15 Hardware Description Analog Inputs Terminal block J1 provides four electrostatic discharge (ESD) protected analog inputs (T_ADC0-T_ADC3) connected to the corresponding ADC0-ADC3 channels of the microcontroller. Refer to the MDL-IDM-L35 data sheet for electrical limits for these inputs. Digital I/O Terminal block J2 provides four ESD-protected digital I/O signals connected to port A (PA2-PA5) of the microcontroller. These can be used to implement an SSI port or for I/O signals as required. Refer to the MDL-IDM-L35 data sheet for electrical specifications on these signals. Headers J4 and J5 provide 12 additional digital I/O lines directly connected to the microcontroller. Header J4 provides 8 digital I/O lines connected to port G (PG0-PG7) with PG0 and PG1 allocated for UART2, and header J5 provides 4 digital I/O lines connected to PA6, PA7, PD0, and PD1. Note that these signals do not have external ESD protection. Serial Header Header J8 is for use with the USB to TTL serial cable, and has connections to UART0 (PA0, PA1) and board power (5 V, GND). This provides a convenient way to power the board and provide a serial connection to update the board firmware. 16 September 7, 2010 C H A P T E R 3 Software Development This chapter provides general information on software development as well as instructions for Flash memory programming. Software Description The software provided with the IDM-L35 provides access to all of the peripheral devices supplied in the design. The Stellaris Peripheral Driver Library is used to operate the on-chip peripherals, the Stellaris Graphics Library is used to render graphical displays on the touch screen, and a set of board-specific drivers are provided to access the off-chip functionality on the IDM-L35. The Stellaris Graphics Library provides two levels of support for rendering graphical elements. In the lowest level, basic drawing primitives are provided, such as lines, circles, rectangles, and text rendering. Each primitive supports clipping to a single clipping rectangle, allowing only a portion of the display to be affected by the drawing primitives. Building upon the drawing primitives is a widget set, which combines the drawing of graphical elements with reactions to pointer events (in this case, presses on the touch screen). The widget set includes push buttons, check boxes, radio buttons, sliders, listboxes, and drawing canvases. By using the widget set, complex interactive graphical displays can be constructed quickly. A set of drivers for the on-board peripherals is also provided. This includes a driver for the touch screen, the audio transducer, the analog inputs, and the microSD card. The IDM-L35 is also supplied with a set of example applications that utilize the Stellaris Peripheral Driver Library and the Stellaris Graphics Library, along with the board-specific drivers for the on-board peripherals. These applications demonstrate the capabilities of the IDM-L35, and provide a starting point for the development of the final application for use on the IDM-L35. All example applications are integrated with the Stellaris boot loader to allow automatic firmware updates to be performed over the serial port using the LM Flash Programmer application. Source Code The complete source code for the IDM-L35 is included on the RDK-IDM-L35 CD. Refer to the Quickstart Guide for a detailed description of initial RDK hardware set up and how to install the source code. The source code and binary files are installed in the DriverLib tree. Tool Options The source code installation includes directories containing projects and/or makefiles for the following tool-chains: Keil™ RealView® Microcontroller Development Kit (MDK-ARM) IAR Embedded Workbench Code Sourcery GCC development tools Code Red Technologies development tools Texas Instruments’ Code Composer Studio™ IDE September 7, 2010 17 Software Development Evaluation versions of these tools can be downloaded from www.ti.com/stellaris. Note that, due to code size restrictions, the evaluation tools may not build all example programs for the IDM. A full license is necessary to re-build or debug all examples. Instructions on installing and using each of the evaluation tools can be found in the Quickstart guides (for example, Quickstart-Keil, Quickstart-IAR) which are available for download from the evaluation kit section of our web site at www.ti.com/stellaris. For detailed information on using the tools, refer to the documentation included in the tool chain installation or visit the website of the tools supplier. Programming the IDM The IDM-L35 software package includes pre-built binaries for each of the example applications. If you installed DriverLib to the default installation path of C:/DriverLib, you can find the example applications for the IDM in “C:/DriverLib/boards/rdk-idm-l35”. The Stellaris LM Flash Programmer is a free tool for programming Stellaris microcontrollers. It can be used in two modes to update the firmware on the IDM-L35. All IDM-L35 example applications are designed for use with the Stellaris boot loader which supports updating of the main application firmware via the serial port. Alternatively, the LM Flash Programmer utility can be used in conjunction with any Stellaris evaluation board to program the IDM-L35. The Stellaris evaluation board acts as a USB-to-JTAG/SWD hardware interface and should be used in cases where the boot loader image is not present or where the main application image is not behaving correctly and cannot transfer control to the boot loader. However, in normal operation, it is more convenient to program via the serial port. To program example applications into the IDM-L35 using the serial port for firmware update: 1. Install the LM Flash Programmer utility on a Windows PC. 2. Connect the 6-pin connector of the USB to TTL serial cable (FTDI part number TTL-232R-3V3) to header J8. Verify that J8 pin 1 (marked by the white triangle on PCB) is connected to the black wire of the 6-pin header. 3. Connect the USB connector of the serial cable to the PC. This provides power and connectivity to the serial port. 4. Run LM Flash Programmer. 5. In the Configuration tab, select “Manual Configuration - see below” in the “Quick Set” list. 6. Select “Serial (UART) Interface” in the list below “Interface” and set the COM port, set the baud rate to 115200, and click the “Disable Auto Baud Support” option. 7. Move to the Program tab and click the Browse button. Navigate to the example applications directory (the default location is “C:/DriverLib/boards/rdk-idm-l35/”). 8. Each example application has its own directory. Navigate into the example directory that you want to load and then go to the /gcc directory (or the directory corresponding to the tool chain you are using) which contains the binary (*.bin) files. Select the application binary file and click Open. Files that start with a “bl_” prefix are boot loader images and cannot be updated using this method. 9. Ensure that the “Program Address Offset:” is set to 0x800. If this is incorrect, the application will not boot correctly once the flash programming is completed. 10. Click the Program button to start the download process. 11. The program starts once the download is complete. 18 September 7, 2010 Stellaris® Intelligent Display Module with 3.5" Display To replace the boot loader image or to program example applications into the IDM-L35 using a Stellaris evaluation board to provide JTAG/SWD functionality: 1. Install LM Flash Programmer on a Windows PC. 2. Connect the 10-pin to 20-pin adapter (included in the RDK) to the evaluation board ribbon cable. This converts the standard 20-pin ARM header on the evaluation board to a fine pitch ARM header. 3. Carefully connect the socket of the adaptor board to J1 on the IDM. 4. Apply power to the IDM and connect the evaluation board (available separately) to a USB port. 5. Run LM Flash Programmer. 6. In the Configuration Tab use the Quick Set control to select the LM3S1968 Evaluation Board. These settings are compatible with the LM3S1958 implementation on the IDM-L35. 7. Move to the Program Tab and click the Browse button. Navigate to the example applications directory (the default location is “C:/DriverLib/boards/rdk-idm-l35/). 8. Each example application has its own directory. Navigate into the example directory that you wish to load and then into the /gcc directory (or the directory corresponding to the tool chain you are using) which contains the binary (*.bin) files. Files named with a "bl_" prefix are Stellaris boot loader images while those without the prefix are main application images. Select the binary file and click Open. 9. Set the "Erase Method" to "Erase Necessary Pages" and check the "Verify After Program" box. NOTE: Setting "Erase Entire Flash" when attempting to replace a main application image will erase the boot loader image and result in a hang when the IDM next boots. If this occurs, reflash a boot loader image using these instructions. 10. If flashing a boot loader image, set the "Program Address Offset:" value to 0x0000. If programming a main application image, set this value to 0x800. 11. Next, click on the Program button to start the Erase, Download, and Verify process. 12. Program execution will start once Verify is complete. The Debuggers in each of the tool-chains also include Flash programming capabilities, including support for high-performance in-circuit debug interfaces.

TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use.
