Led On Communication

lolobond

Hi, I am a beginner in spin language and I would appreciate ideas on how to write a spin language code that expects to receive a number '1' from a matlab program and after receiving the number turns on a led of the PE microcontroller. This is my way to confirm that there is communication between MATLAB and the propeller chip.

Thank You

Below is some simple code that worked for me on using FullDuplexSerialPlus an a demoboard

CON

  _clkmode = xtal1 + pll16x
  _xinfreq = 5_000_000
  
rx = 31
tx = 30

baud = 9600
OBJ
ser   : "FullDuplexSerialPlus"

PUB main  |  Number

ser.Start(rx, tx, 0, baud)
waitcnt(clkfreq+cnt)

repeat
  Number := ser.rx
  if Number == "1"
    dira[16]~~
    outa[16]~~

Thank You! I will try it soon and let you know how it did. Do you know if it can be used for FullDuplexSerial? I don't have the FullDuplexSerialPlus program included on the files that the parallax software has.

FullDuplexSerial is readily available on OBEX.

It is not working. Does it matter if what I expect to receive from Matlab is a numeric one? Do I need to change anything? My simple Matlab code is below

s=serial('COM3','BaudRate',9600);
fopen(s);
ledon=[1];
fwrite(s,ledon)
fclose(s);

Thank You
