10. Troubleshooting
In some cases it might happen that the connection to the 78K0R – Say it! can not be established. This can be
caused by the following two situations:
•
Wrong security ID: The security ID is required to prevent the FLASH memory of the 78K0R/KG3
microcontroller from being read by an unauthorized person. The security ID is located in the internal
flash memory at addresses 0xC4-0xCD of the 78K0R/KG3 microcontroller. The IAR C-SPY
debugger starts only when the security ID that is set during debugger start-up and the security ID set
at addresses 0xC4 to 0xCD do match.
•
Disabled On-Chip debug: The On-Chip debug function of the 78K0R/KG3 microcontroller can be
controlled by a dedicated Option Byte located at address 0xC3 in the internal flash memory. By
disabling the On-Chip debug operation no connection to device can be established neither using the
TK-78 interface nor using the QB-MINI2 On-Chip debug emulator.
In the above mentioned cases it is necessary to erase the internal flash memory of the 78K0R/KG3
microcontroller to restore the security ID and to enabled the On-Chip debug function.

11.2 “78K0R_Sayit_VoiceDemo_Obj” sample program
This sample program is a simple sound play application that uses the ADPCM compress/decompress library.
The sample is divided into three major parts, the sound play, beep play and illuminance sensor application.
Please use the source code of the different application parts as reference on how a sound play system based
on the 78K0R device can be realized. To get more details on the source program itself, please refer to the
following chapters. Because the 78K0R – Say it! starterkit comes with the IAR Embedded Workbench
Kickstart version – which is limited to generate maximum 16KByte of code size – the sound data within this
sample is provided as object code, files “adpcm*.r26”. If you want to change the sound data please refer to
the sample “78K0R_Sayit_VoiceDemo_Src”, chapter 11.3 of this document.

11.2.1 How to run the sample program
The sample program supports the following three modes.
•
Sound Play Mode
Within this mode the 78K0R – Say it! board plays one of four sounds. The selection
of the corresponding sound data to be played can be done by the navigation switch SW1.
•
Illuminance Sensor Mode
By using this mode the light radiation is determined via the A/D converter by measuring the
output voltage of the onboard illuminance sensor. The light radiation is displayed by the
VOLUME LEDs. Additionally, pending on the light radiation the speech data "It got dark" or "It
got light" is played by driving the onboard loudspeaker.
•
Beep Play Mode
This simple demo, outputs alternately a high pitched, silent and low pitched beep sound by
driving the loudspeaker.
11.2.2 Sound Play Function
This sample application plays a selected sound from a set of four different sound data. To run this function
please set switch SW5 / bits6-8 to “OFF”. Depending on, if you want to run the sample within stand-alone
mode or if you want to use On-Board debugging please set the bits1-5 of configuration switch SW5
accordingly.

Function
This selects the wave output via PWM or D/A. The PWM LED and
D/A LED shows which output mode is selected. The mode cannot
be changed while the sound data is played.
This changes the sound output volume. There are 9 volume levels:
OFF, 1-8. The VOLUME LEDs are showing the selected level. The
sound volume can be changed during sound it played.
The sound playing can be started, paused or stopped by pressing
the navigation switch. Pressing the switch when a sound is playing
pauses the sound output. Within the pause mode the PLAY LED
starts blinking. By pressing the SW1 for more than 1.5 seconds the
sound output is stopped. Playing of the sound can be started by
pressing SW1 one’s again.
This selects the sound data to play from totally four sound data
stored in built-in FLASH memory of the 78K0R/KG3 device. The
SOUND LEDs 1-4 shows which sound is actually selected. The
sound data cannot be changed while the sound data is played.

11.2.3 Illuminance Sensor Function
By using this mode the light radiation is determined via the A/D converter by measuring the output voltage of
the onboard illuminance sensor. The light radiation is displayed by the VOLUME LEDs. Additionally, pending
on the light radiation the speech data "It got dark" or "It got light" is played by driving the onboard loudspeaker.
The corresponding speech data is stored in the “adpcm1.r26” and “adpcm2.r26” object files. If you change
the sound data by re-flashing of the corresponding memory area different sound data can be played.
To run this function please set switch SW5 to the following configuration.

11.3 “78K0R_Sayit_VoiceDemo_Src” sample program
This program has the same functionality like the “78K0R_Sayit_VoiceDemo_Obj” sample described in
chapter 11.2. By using this sample you are able to change the sound data and replace it by your own
preferred sound data. For this purpose the project is split into the main application - project
“78K0R_Sayit_VoiceDemo” - and four sound projects “ADPCM_Sound1” to “ADPCM_Sound4”, containing
the sound data. The corresponding workspace and the partitioning of the projects can be seen in the figure
below.
The main project doesn’t contain any sound data. The reference to the sound data itself is done by pointers
to the corresponding sound data areas. For each of the four sound data a fixed memory area is defined. The
corresponding mapping can be seen in the figure below.

The assignment of the memory for the different sound data is done within the linker directive file
“lnk78f1166_adpcmsp.xcl”, which is mutual for the main and the four sound data projects. Each sound data
area contains about a ADPCM_FORMAT, ADPCM_SIZE and ADPCM_DATA section. The definition and
mapping of the corresponding sections within the linker directive file can be seen in following figure.
The projects “ADPCM_Sound1” to “ADPCM_Sound4” do include only the corresponding sound data for the
four sound data areas. The definition of the sound data is done within the “adpcm.c” file. This file contains the
definition of the sound format, the sound size and the raw sound data. The sound data itself is generated by
the CvADPCM converter tool. The figure below shows for instance the definition for the sound data area1.
User’s Manual U19237EE1V0UM00
56
78K0R - Say it!
The definition of the sound format and sound size is done by the constants “adpcm1_format” and
“adpcm1_size”. They have to be set according to the sound data file, in this example the file “Speech_01.c”,
generated by the CvADPCM converter tool. The sound data file itself is included and placed to the
“ADPCM1_DATA” section. Analog to this, the format and size information is placed to the
“ADPCM1_FORMAT” and “ADPCM1_SIZE” sections. The three sections are referenced and accessed within
the main sample project via pointers. The creation of the sound data is done by simply re-building the
corresponding project. By doing so an Intel-Hex file is generated that is mapped to the corresponding sound
data area. To download new sound data to the 78K0R – Say it! board and furthermore to re-flash the
reserved sound data area within the 78K0R/KG3 device please press the ( ) “Debugger” button within the
IAR Embedded Workbench. Note, be sure that the function “Erase flash before next ID check” is not active
within the “TK-78 Hardware Setup” menu. Otherwise the complete FLASH memory of the 78K0R/KG3 device
will be erased before programming the sound data.
don’t enable
After the IAR C-SPY debugger has finished re-programming of the chosen sound data area, please close the
debugger. The new sound data is now successfully updated. Please proceed in the same way for the
remaining sound areas. Because the 78K0R – Say it! starterkit comes with the IAR Embedded Workbench
Kickstart version, the maximum size for each sound data is limited to 16KByte. After you have programmed
or changed the sound data, please activate the “78K0R_Sayit_VoiceDemo” project and debug it as usual.
Please note, also by debugging the sample, be sure that the function “Erase flash before next ID check” is
not active within the “TK-78 Hardware Setup” menu. Otherwise the complete FLASH memory of the
78K0R/KG3 device will be erased before programming the sample project and the sound data gets lost.

11.4 “78K0R_Sayit_DownloadDemo” sample program
This sample application allows you to download and modify the four different sound data areas by using the
CvADPCM tool. Additionally it offers the same sound play function like the “78K0R_Sayit_VoiceDemo”. The
CvADPCM tool uses the USB interface and the UART3 of the 78K0R/KG3 device for communication.
Consequently the TK-78K0R On-Board debugging function can not be used by running the
“78K0R_Sayit_DownloadDemo” program. The 78K0R – Say it! starterkit comes with this sample program as
default configuration. The “78K0R_Sayit_DownloadDemo” is provided as HEX file only.
Please note, by using the download sample the sound data size for each sound data area is limited to

78K0R - Say it!
In case of 32Kbps compression, 1 sound data is represented by 4 bits. This means, that 3 byte of memory
can included 6 sound data packages.
In case of 24Kbps compression, 1 sound data is represented by 3 bits. If you just use 1 byte, it causes a
fraction. This fraction should be treated as connected 3 bit with the last bits of following byte. This means that
you need 3 byte of memory to include 8 sound data packages.
In case of 16Kbps compression, 1 data is data is represented by 2 bits. This means, that 3 byte to memory
can carry 12 sound data packages.
As it mentioned previously, the compression/decompression library processes the decompression to DTn.
Therefore, the application needs to gain the compression bit information of 8 bit sound data.
11.5.4 Output Cycle and Interruption
This application targets to the sampling cycle of 8KHz. This means that it plays sound data once in 125µs. It
depends on speaker play band and hearing sense of people, but it means the sound in 8KHz. Based on this,
the application outputs the same 16KHz (62.5µs) data for 2 times.

① "i==0" indicates "dark".
To prevent for outputting the sound repeatedly by keeping the “dark” status, it contains the
statement "playEndFlg_Low==0" (it is "still" dark).
With the statement "uiIntCounter1 > KEY_LONG_ON_TIME", it can check if it passed off
certain period of time. "uiIntCounter1" is general purpose 1msec counter using cycle interrupt.
Since "KEY_LONG_ON_TIME" is set to "1500", the cycle is more than 1.5 seconds.
When it meets the condition, it sends the play sound number with "play_num = 1", and play
permission with "playEnvflg = 1" to output process.
② "i>7（==8）" indicates "light".
In the same way, it contains the statement "playEndFlg_High==0" (it is still “light”) to prevent
outputting the sound successively.
When it meets the condition, it sends the play sound number with "play_num = 2", and play
permission with "playEnvflg = 1" to output process.
③ If other than above, clear the cycle interrupt counter.
④ When the Illuminance level is close to intermediate level, initialize those flags to be able
to check light/dark.

}
① Start the A/D conversion. It needs to wait 1µs after setting the "ADCE".
② Skip the first conversion data.
③ Sample illuminance sensor data.
It samples 64 times, and calculates the average value.
Again, it samples 64 times, and calculates the average value.
This loop process uses about 55ms. During this time, it rounds the value from illuminance
sensor (about 5 times).
④ Stop the A/D conversion.
