TRANSMIT_FIFO_INDEX is 0 (should be 2)

[PeterOGB]

I haven't been able to build your Arduino code as I don't have a suitable shield for an Arduino, but I am using it as a starting point for code to run on a Pi PICO with a MCP2518 attached.
Looking at the code I se TRANSMIT_FIFO_INDEX is defined as 0, but functions like C1FIFOCON_REGISTER() expect 1..31 (according to the comments).
I think using C1FIFOCON_REGISTER (TRANSMIT_FIFO_INDEX) will produce a register address for CiTXQCON (0x50) not CiFIFOCON1 (0x5C).

Hello, I think the ACAN2517 library works with a Pi Pico. The ACAN2515 runs on Pi Pico, I use the Earle F. Philhower board manager, it is very stable, more than Arduino Mbed Os RP 2040 one. Where did you see that TRANSMIT_FIFO_INDEX is defined as 0 ? In ACAN2517.cpp file, line 160, it is set to 2 : static const uint8_t TRANSMIT_FIFO_INDEX = 2 ; Pierre
