Other Parts Discussed in Thread: TCAN4550
I am attempting to interface the TCAN4550 EVM with a non TI MCU and am running into some issues. I am using the example project and changed the AHB functions to fit the SPI library of my chip.
The SPI appears to be working when watching it with a scope however, no CAN messages are ever sent. When I reset and wake the board manually the nINT and nWKRQ lights are on but after configuration those lights turn off and the INH light turns on.
My connections are as follows:
GND: SRC GND
VIO: 3v3 from MCU board (s1 in 3v3 position)
SCLK: MCU SCLK
SDI: MCU MOSI
SDO: MCU MISO
nCS: MCU CS
