Hello :
I am using the can transceiver TJA1145T,and I can not get the right response when I send a 0xfd to it,I am sure I have the right connection among the pins,when I monitored the SDO pin of the TJA1145T, I found it copy the information I send to it from the pin SDI sometimes,why could this happen ?Can anyone help me?
best regrads!
