Other Parts Discussed in Thread: HALCOGEN
Tool/software: Code Composer Studio
i have a question please i have a sensor with (LIN protocol and operating voltage of 12v )so i connected SPI to CAN FD SBC+LIN Transceiver boosterpack from TI with LIN driver of tms570ls1224 .but i didn't get the sensor data.
IN Halcogen i leave the default settings just i enabled Rx interrupt (TX/RX-Mask both set to 0xFF HGEN = 1 and using master mode with 20k baudrate)
1)the sensor write settings frame : break+syn+ID(0x38) ,PID(0x78) +data1(0x01)+data2(0x02)+checksum
2)delay 1s
3)the sensor read data frame :break+syn+ID(0x01) ,PID(0xC1) and Will return 8 data bytes.
i checked the sending data by oscilloscope it displays
so i write the main code as following. could you help me
