The board has passed a authentication test so I currently believe it is a me issue.
I have been trying to get a CAN bus going using the STM32 Blue Pill board with a TJA1050 CAN Transceiver, but for some reason even with basically copy pasted example code I don't even get activity on the lines. The transceiver modules I am using has the CAN bus terminating resistors built in resulting in a 60ohm resistance between the H and L lines. I've ended up putting together a basic test Tx and Rx bread board in hopes of figuring out whats going on with no clues. The Tx loop eventually goes dead for some reason which makes me think the HAL_addTx started locking up. Linked is a github repository with both projects. Also a video of the boards.
