T bit confusion
Hi,1.As it is mentioned in CM4 user guide and also explained in tutorial, 0th bit of PC is directly loaded to T bit.And CM4 supports only thumb state ISA.To execute/decode instructions in Thumb state 0th bit of PC should be 1 which means PC should al...
STM32F7 MCU CAN error passive interrupt can only be triggered once
When a CAN message is not ACKed by other nodes, if auto re-transmission is set, bxCAN will re-transmit the message infinitely. This floods the CAN bus, especially if the message is of high priority.My solution is to enable the error passive interrupt...
