SPEED CAN-BUS inernal external

Looks like you are using software SPI, could you try a different Sample Point, e.g. Middle?
Also the "While Free1" loop should have the test the loop at "End"

This variant sends only one message

Code: Select all

36,010 6C1      8 01 01 00 03 00 00 00 00 ASCII: 

And it always compile hex with mistake in configuration chip. It sets bits 5 and 7 in address 30000 as 1. But they can't be set as 1.

so you need to go back to the version that masks the status with 0x04, just to get the Tx Buffer 0 status
