The read byte, read bytes and timeout functions have been 'discovered' already. Highly recommended when conversing and talking to picaxe etc.
I imagine it would be somewhere between the port command and the port.readline() command I imagine.įor anyone interested the above port.readline() example works FAB with serial data arriving at the GPIO ad hoc / variable length and responds to the 13/10 LF/CR very nicely. Can someone indicate where and how such a clear buffer command would go in the above example so it runs once on startup. #This sets up the serial port ttyAMA0 GPIOĢ/.
Port = serial.Serial("/dev/ttyAMA0", baudrate=2400) Import serial, time #this imports the libraries needed This can be time consuming / messy esp if processing and forwarding data off the UART as we are doing to a web server etc. When (re)starting the program the Pi seems to have happily accumulated everything and anything seen on the UART Rx line. Would be interested in how to clear the input serial buffer (and output ?) as the following program example starts.
