The pin definition table in the STM32 datasheet states that CANtx & CANrx are available as remap functions for VFQFPN36 on pins PD0 & PD1. However the AFIO section in the reference manual says that PD0 & PD1 are only available for remapping for the 100 and 144 pin packages. Which is correct?
I would like to piggy-back on your question if i mayI have 64pin package. I hear a lot that it's either USB OR CAN (not both) for this chip. But now i read about the remapping and seems like with 64pin package it's possible to remap to PB8, PB9 for CAN hopefully someone who actually tried this CAN remap chimes in
From what I understand, you can remap, but you still can't use CAN and USB at the same time. They share the same memory:From the Reference Manual-> Note: The USB and CAN share a dedicated 512-byte SRAM memory for data transmission and reception, and so they cannot be used concurrently (the shared SRAM is accessed through CAN and USB exclusively). The USB and CAN can be used in the same application but not at the same time.
