mbedDebug.c – debug device I/O functions
The debug functions communicate with the host computer using a serial link.For mbed, this is the SerialPC link, which is on UART0. Note that on Windows a driver must be installed for this to work. See: http://mbed.org/handbook/SerialPC
| 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
It is recommended that a ‘standard’ baud rate be used, e.g., 9600 or 115200.
At 9600 about 38 characters can be sent in 40ms (one major tick); at 115200, 460 can be sent.
debugPutcIO – send character to debug terminal
void debugPutcIO(int ch);
ch – character to send
This waits for any previous send to complete.
