Hardware setup
The main board components are shown on Figure 2.
Figure 2.
3.1
Setup of the board
Power supply
The board is powered by a 7.5 to 18 V DC voltage. The power source must be able to deliver
a 0.7 A current. Since the board has a built-in diode bridge, the polarity of the input voltage
is not specified.
3.2
Microcontroller JTAG
The board is equipped with a standard 20-pin JTAG connector allowing to debug and
develop the STM32 microcontroller.
3.3
Microcontroller clock, reset, USB clock
The STM32 on-board microcontroller uses its internal RC oscillator to generate an 8 MHz
clock (that is converted to 48 MHz by a PLL). The clock is also used to drive USB. Since the
internal RC oscillator does not allow to achieve the clock stability defined in USB
specifications, it is recommended not to use the internal RC oscillator in conjunction with the
USB interface. The USB is used only for demonstration purpose, but the performance is
limited due to this internal RC oscillator stability.
3.4
Jumpers for LED failure simulation
LED defects can be simulated by using P20, P21 and P22 jumpers:
6/20
●
Removing a jumper on P20, P21 and P22 causes D1, D2 and D3 green LED opencircuit
●
Placing a jumper on P1, P2, and P3 causes D6, D9 and D12 blue LED short-circuit.
These simulated defects can be detected during the activation of the error detection
mode (see Section 4). The defective LED is highlighted by switching on the
corresponding red LED.

Description of the demonstration firmware functions
Description of the demonstration firmware functions
The main features of the firmware are:
●
Brightness control for each LED
●
Color control for each LED
●
Error detection to detect LED failure
●
Simulation Tetris game.
The RGB LEDs are switched on to display letter 'A', 'B', 'C' or 'D'. Each letter represents
a menu option (or mode).
The firmware mode menu items:
●
Mode “A” interactive demonstration - color Tetris
●
Mode “B” wave color demonstration
●
Mode “C” solid color demonstration
●
Mode “D” error detection demonstration.
After power-up, the letter 'A' is displayed blinking. An action on a button or on the knob
allows to select the required mode and display another letter.
Figure 3.
The menu; the letter “A” indicates the first item of the menu
The board can be controlled by four buttons and one knob, Figure 4:
●
Button back/reset - exit from current task in to the main menu
●
Button left - turn the mode menu decrementally
●
Button center - enter the choosen mode in menu
●
Button right - turn the mode menu incrementally
●
Knob - changes the color of the menu from blue to red.

Description of the demonstration firmware functions
4.1
UM0882
Mode “A” - interactive demonstration - color Tetris
Mode 'A' performs a simple interactive demonstration similar to Tetris game. The game
starts with a green brick moving from the bottom to the top of the LED area. The brick
position can be controlled by using the right and left buttons. Once the brick reaches the top
of the LED area of another already settled brick, it stops and turns to blue. A blue brick
cannot be moved. When a row is full of blue bricks, it disappears and the player scores
points. The game ends as soon as the blue bricks reach the bottom of the LED area. When
the game is over, the score is displayed. Pressing the center button starts a new game. The
knob changes the light brightness of the LEDs.
4.2
Mode “B” - wave color demonstration
Mode “B” shows different color effects. The effect can also be changed manually by using
the center button. The knob changes the speed of the effect.
4.3
Mode “C” - solid color demonstration
Mode “C” allows to display a given color on the LEDs. Pressing the right button changes the
colors in this order (left button in reverse order): red, green, blue, yellow (red + green), cyan
(green + blue), magenta (red + blue), white (red + green + blue) and black (all LEDs are off).
The knob changes the light brightness of the LEDs.
4.4
Mode “D” - error detection
Mode 'D' performs LED error detection, and displays the error. Error detection is performed
by LED drivers every 2 seconds. If a defective LED is found, it is signalled by switching on
the corresponding red LED. D1, D2 and D3 green LED open-circuit defect can be simulated
by removing P20, P21, or P22 jumper. D6, D9 and D12 blue LED short-circuit defect can be
simulated by closing P1, P2, or P3 jumper.

PC demonstration firmware software
PC demonstration firmware software
PC demonstration software supplied with the board can work together with the board
firmware using USB interface. The software can detect the board, drive it by mouse instead
of the on-board buttons, trigger and visualize the result of the error detection.
Figure 6.
Software - Windows® application
The following steps are required to run the PC demonstration software correctly:
1.
Disconnect the power supply from the board.
2.
Connect the board to the computer through the USB cable.
3.
Connect the board to the power supply.
4.
If Windows asks for the installation of an appropriate driver, use STMicroelectronics
VirtualCOMPort.

To perform error detection, click “Perform error detection”. Error detection is performed
correctly and does not depend on the board operating mode.
Figure 12. Error detection mode performed
The evaluation of the error detection through the USB interface:
12/20
1.
Jumpers P20, P21 and P22 are closed and the jumpers P1, P2 and P3 are open, the
PC demonstration software will not report any LED defect after clicking ”Perform error
detection”. See Figure 12.
2.
Moving the jumper from P21 to P2 after performing error detection will display the
simulated defective green LED on the first row and second column, and the simulated
defective blue LED on the third row and third column.
3.
Exit the PC demonstration software, and disconnects the board. You can then start
testing another board.
