I also have a SAM D21 Xplained Pro board. Does Atmel Studio support the printf function to print to the virtual serial port, or semihosting? I have used Nuvoton before and they all have this mechanism...
After using serial_8250.c for porting, there is a problem with the interrupt processing function. When data is sent to 16554, 16554 can generate a high-level interrupt signal, but the high-level signa...
I am using AT89S52. Everything is fine in my simulation in PROTUES. This should prove that there is no problem with the program, right? But after I soldered the board, the digital tube did not display...
