Now think of is the debug debugging and printf information step by step to the serial port, there are other good method?

CodePudding user response:

Can also use a serial port interrupt to do some commands, such as via a serial port to send a p command to program MCU to stop, what other commands, or send a to perform some other task

CodePudding user response:

No other good method

CodePudding user response:

Directly attached to debug program, many models of the chip can directly through the programmer debugging (STM32, new tang, on STC, etc.)

CodePudding user response:

Gpio or write memory, a lot of time to print behind need to write memory

CodePudding user response:

Step through really couldn't keep up with the CPU speed
