Other Parts Discussed in Thread: HALCOGEN, TMS570LS2124, TMS570LC4357, TMS570LS1224

While   using   i2c   protocol    TMS570LS4357   as   master     TMS570LS2124   as    Slave    please  provide   me   halcogen   set  up    ,then    while  excuting   the  example  code   it  is  get   struck   in   while loop 

while(i2cIsStopDetected (i2cREG1) I2C_SCD_INT);    HOW  over  come   from  this  problem  , please  provide    one  solution   as  soon as  possible   

thank you   for   help

    Hi Jeeva,

    What are the values of external pull-ups you are using?

    0636.I2C_TEST_LC43.zip

    Can you please verify your code with above tested example once?

    Okay, but i would like to know the external pull-up values you are using on SDA and SCL lines?

    Hi Jeev,

    I will provide you an update on monday, as it is a weekend i don’t have setup with me right now.

    Mean while please attach your master and slave projects.

    Thanks,

    Hi Jeev,

    Today i tested your codes on my boards.

    On my testing, i used

    TMS570LC4357 as Master 

    and RM57L853 as slave because i don't have TMS570LS1224  board.

    Here are my testing projects:
    3617.I2C_TEST_LC43.zip

    RM57_I2C_Slave.zip

    And after my testing, i didn't see any issues in my testing. I also attached the logic analyzer and monitor the signals.

    Here is the output of the logic analyzer.

    I could see, you are sending 11 bytes with time difference of 36.66mSec

    And first two times you are sending below data:

    Slave address(0x08) And 0x10 to the 0x19 data to the slave.

    And Next two times you are sending below data:

    Slave address(0x08) And 0x20 to the 0x29 data to the slave.

    So my suggesting here is below thing:

    1. On my testing i used 2.2K pullup resistors. And make sure to use only one pair of pull-up resistors, i mean don't use pull-up resistors on both master and slave sides because if we did that the overall pull-up resistor value becomes 1.1k.

    2. Even though i used same as your code but my HALCoGen configuration is not same as yours, so my sincere suggestion here is just cross check my HALCoGen configuration files of master and slave with yours. Because your initialization code and my code might be different. So please do that.

    If you follow above two suggestions, i think your code also should work.

    Thanks & regards,
    Jagadish.
