Other Parts Discussed in Thread: TMS320C5515, ADS1298

Hello Everyone.

I am a beginer on DSP and I started my project with great deffeculty. I have 2 quite new tool KIT, they are TMS 3205515 EVM & ADS 1298 ECG FE. I want to sent data from ADS2298 ECG FE to TMS 3205515 EVM by SPI. I have read "TMS320C5515 DSP Serial Peripheral Interface (SPI) User's Guide" but I am still vague. I don't know how to start coding. Can you plese help me any very very simple example about SPI. I realy need the help.

Thanks for any help.

    Hi,

    Please use CSL from http://www.ti.com/tool/sprc133. There is SPI example code.

    Regards,

    Dear guys;
    I am following an application report given below link:

    http://www.ti.com/lit/an/sprabj1/sprabj1.pdf

    I have TMC320C5515EVM and ADS1298 ECG FE board.PCB had been drawn previously and had been drawn to be with some difference in connections: CS0 of TMS3205515 was connected to EEPROM but ADS1298 was connected to CS1 of the TMS320C5515.In addition to this,PCB do not have a JTAG connection or on-board emulator for code debugging.

    I checked the firmware but since I am not familiar with programming in TMS320,I got stucked because code seemed very complicated to me.I dont want to loose time to  try understanding the code completely.Thus I need your help

    May I ask you to help me to make required modifications over the code related to change CS0 connection to  CS1?

    If I write the image file into the EEPROM on CS0 pin,is it possible to boot the program from EEPROM?
    If it is possible to boot,does the modified code run and start communication with ADS1298?


    Regards
