Other Parts Discussed in Thread: TMS3705, TMS37157

Hi, 

Im intending to read a TRPGR30TGC transponder and I have a board RI-ACC-ADR2-10 using tms3705 . Do you have any source code  available for that ?

regards,

Bruno

    in the LF.c file of the source code given on the web, you just need to comment out the PWM and BLC times used for TMS37157 and add these lines of code

    PWMtimes.usToffH  = 1000; //timings for RO_RW

    PWMtimes.usTonH   = 1000;

    PWMtimes.usToffL  = 300;

    PWMtimes.usTonL   = 1700;

    BLCtimes.usToff  = 170;

    BLCtimes.usTonL  = 230;

    BLCtimes.usTonH  = 350;

    BLCtimes.usTonSC  = 600;

    then you can hook up a scope and make sure its working correctly according to the attached notes i took
