TMS320F280041: LIN Interrupt problems

Hello,

when using LIN_disableSCIInterrupt(LINA_BASE, LIN_SCI_INT_TX) it also disables LIN_SCI_INT_RX. Same other way around.

Also tried example lin_ex2_sci_loopback which worked fine. But when putting LIN_disableSCIInterrupt(LINA_BASE, LIN_SCI_INT_TX) after LIN_writeSCICharBlocking (line 173) it also stopped working.

So why LIN_disableSCIInterrupt() disables both ?

Thank you for helping.

Hi Celil,

Thanks for your question. You can optionally directly write the registers using the "HWREG*" functions in C2000Ware if you want to write these individually.

Regards,

Vince

Thank you for your answer.

LIN_disableSCIInterrupt uses '|=' which results in setting all registers to 0, there should be a '=' instead

this solves also my problem to call HWREG_BP directly but with '='

Best regards
