Prop to Python troubles

AGCB

I'm just learning to use Python in some very simple programs. I have gotten Arduino to talk to the Python program, but can't seem to figure how to get Prop to do the same.

I've been trying to use the Full Duplex Serial object. (or FDS Plus, have also tried PST) Maybe I'm wrong on this.

Here is the simple Python program

import serial


PropData = serial.Serial('com4',115200)

while (True):
    
    if (PropData.inWaiting()>0):
        myData = PropData.readline()
        print myData
        

And here is the Arduino program that works

int cnt=0;
void setup() {
  Serial.begin(9600);
}
void loop() {
  Serial.print("I am counting to: ");
  Serial.print(cnt);
  Serial.println(" Mississippi.");
  cnt= cnt+1;
  delay(1000);
}

And here is the prop program that doesn't work

CON       
  _clkmode = xtal1 + pll16x      '80 MHz system clock
  _xinfreq = 5_000_000

OBJ
  fds  : "fullduplexserialplus"
 'fds  : "parallax serial terminal" 
VAR
  byte num 
PUB main
  fds.start(31,30,0,115200)
  repeat   
    fds.dec(num)
    fds.str(string("  one-thousand  "))
    waitcnt(clkfreq+cnt)
    num++

I know it looks like baud rates are different (they are for the Arduino and prop programs) but they are right (matched) when I use them. The com port is also matched for each program.

So my ? is, am I using the FDS right or is there something better or easier? I get no errors but no output from the Python when using the Prop

Thanks

You are using println in the Arduino program but you are not sending out a new line in the Spin program. Perhaps your Python code needs to see a line termination (readline).
Try fds.str(string(" one-thousand ",$0d,$0a))

Thanks Peter. I'll try that right away (on a different computer)

Thanks Peter, That did it!!
