pri2Debug.c – debug device I/O functions
The debug functions communicate with the host computer using a serial link over a USB Virtual COM port.For primer2, this is via the “STM32” USB connection.
Note that on Windows a driver must be installed for this to work; this should be automatic (using Internet search).
| Functions | |
|---|---|
| debugGetcIO | get character |
| debugInitIO | initialize port for I/O |
| debugPutcIO | send character to debug terminal |
debugGetcIO – get character
int debugGetcIO(void);
returns character read from host, or −1 if none there
This function does not block.
debugInitIO – initialize port for I/O
void debugInitIO(uint baud);
baud – rate to run debug communications
The baud rate is ignored because this is a Virtual COM port.
debugPutcIO – send character to debug terminal
void debugPutcIO(int ch);
ch – character to send
This does not block; if too many characters are sent they will be quietly discarded.
