| May 29 at 5:28 | comment | added | the busybee | Please add a link to the user manual and/or programmer's manual, which includes detailed descriptions of all registers, especially of the pin configuration. | |
| May 28 at 10:11 | comment | added | Lundin | I have never used a MCU that would allow these pins to be routed individually - you typically have to port route the whole CAN controller peripheral as one, and only to certain pins. Check the part of the MCU manual that speaks of "routing registers" or some such. | |
| May 28 at 9:46 | comment | added | Finbarr | What does the datasheet say about the options for CAN TX and RX pins? Based on the schematic they appear to be fixed and can't be swapped. | |
