TXZ3 setting

  STEP 1 : Hardware 

easyDSP uses MCU's single boot mode to access the flash memory. So the UART0 channel (PA1/PA2) that is used in the single boot mode should be used for easyDSP.
Otherwise, easyDSP can support only monitoring, not flash writing. Also the source file easyTXZ3.c should be modified accordingly by you.

Other considerations :
- DVDD could be either DVDD3 or DVDD5.
- In case there is a reset IC between easyDSP /RESET and MCU -RESET, it should transfer easyDSP /RESET signal to MCU -RESET within 0.5sec.
- In case pull-up resistor is attached, resistor value should be higher than several k Ohm.

STEP 2 : Modification of easyTXZ3.h file 

Two files are provided for easyDSP communication (easyTXZ3.h and easyTXZ3.c). Please include them in your project. You can find them in the easyDSP installation folder (\source\TX_TXZ).
Since Peripheral Driver library from the MCU supplier are used in the files, this library should be included in your project.

First, include the CMSIS header file according to target MCU.
Finally set the baudrate of easyDSP communication. The baud rate should be same to that of easyDSP project.

 

 

STEP 3 : Calling easyDSP_init()

Pleae include easyTXZ3.h in the main.c and call  easyDSP_init() in the main() after the initialization of others.


 

STEP 4 : IDE setting

1. Hex file (Intel format) is used for flash programming. So it should be created in every compiling time in the same folder to output file (ex *.elf) with same file name. The hex file extension could be either 'hex' or 'ihex'. easyDSP first check if the hex file with extension 'hex' exists and use it for flash programming. If the hex file with extension 'hex' doesn't exist, easyDSP uses the hex file with extension 'ihex'. Pleae set your IDE accordingly to create hex file in every compiling time. 
2. For easyDSP to access the variable, the debug information should be included in the output file (ex, *.elf). And the option of assembler, compiler and linker should be set accordingly.
3. The unused variables could be excluded from the debug information depending on compiler's optimization level and linker setting. If necessary, you can set the linker option so that the unused variables are not excluded.  
4. To compile inline functions in the easyTXZ3.c, plase enables c99 mode in the compiler options if required.
