STEP 1 : Hardware
Please connect easyDSP header RX and TX pins to directly UART pins (either P1.3/P1.2 or P0.14/P0.15 pair).
RX and TX pins of easyDSP header are pulled up with 100kOhm resistor in the pod.
Also connect easyDSP header #4 pin to VDDP.
STEP 2 : Modification of easyXMC1.h file
Two files are provided for easyDSP communication (easyXMC1.h and easyXMC1.c). Please include them in your project. You can find them in the easyDSP installation folder (\source\XMC).
Since XMC Peripheral Library is used in the files, this library should be included in your project.
And modify easyXMC1.h file according to your target USIC channel and baudrate.
The baud rate should be same to that of easyDSP project.
Also allocate 8 receive FIFO buffer and 8 transmit FIFO buffer to the channel of USIC easyDSP uses while avoiding conflict to FIFO buffer of the other channel of USIC module.
STEP 3 : Calling easyDSP_init()
Pleae include easyXMC1.h in the top of main.c and call easyDSP_init() in the main().
STEP 4 : IDE setting
1. 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.
2. 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. For example, in the Dave, set the 'Remove Unused Sections' unclicked.
