Overview[Bearbeiten | Quelltext bearbeiten]
serialUSB is a c code-example for STM32F4xx.
It will create a virtual com port VCP using the built in USB device stack. On the host PC the VCP acts like a physical terminal (COM-port).
The default device name is /dev/ttyACM0 .
Make sute to blacklist the device and/or shut down modem-manager as it tries to sent AT-commands to it.
/dev/ttyACM0 can be accessed like any other terminal /dev/tty0 (physical) or /dev/ttyUSB0 (PL2303).
Virtual Com Port[Bearbeiten | Quelltext bearbeiten]
void VCP_send_str(uint8_t* buf)
will sent a string to host
note: too long strings may cause buffer overrun
void VCP_put_char(uint8_t buf)
will sent a single char to host
uint8_t VCP_get_char(uint8_t *buf)
nonblocking:
return 1 on success, 0 otherwise
on success buf contains the read character
uint8_t VCP_get_string(uint8_t *buf)
nonblocking:
return read bytes on success, 0 otherwise
on success buf contains the read characters
