Hi,
Basically I followed those 2 pages I listed before - Trying to use PySerial to drive a serial lcd (parallax)? - this one provides the following python code that I used:
import serial
ser = serial.Serial(“/dev/ttyS0”, 57600)
ser = serial.Serial(“/dev/ttyGS0”, 9600)
for i in range(10): #I added these 2 lines
ser.read()
I just added a loop for it to listen to a certain number of requests. I could send data from the serial monitor in the IDE and it would display in python. So the /dev/ttyS0 port could be monitored in this way. I am trying to write data from sensors to the /dev/ttyS0 UART from the sketch - and I tried serial.print(data); and serial1.print(data) and serial2.print(data) but I never receive any data from the ser.read() in pyserial.
I hope that makes sense - thanks for the quick response.
