I am having a problem communicating with an LED. (Never thought I'd hear myself
say that!)
I have code in LC in a slider:
-- We are open driver ... for text update
on mouseUp
put the thumbPosition of me into tValue
doUpdate(tValue)
end mouseUp
on doUpdate tValue
put gThePort into theP
Try:
write numtochar( tValue ) to file thePort
This will only work for values less than 256, however. You can increase that
range by breaking the number down into individual bytes and sending those in
sequence.
What you should do instead is send the number as ascii as you are now, but
end it wit

For safety's sake...

Well, Thank you very much the numtochar worked perfectly. SInce most of these
are either two or three numbers being sent for motor/stepper and LED and will
not be more than 255 I will stick with the numtochar() for this. I will still
try to come up with a parser for the Arduino for passing comma
Is this right?
char cmd[255];
int param = 0;
char buf[255];
int bufloc = 0;
while ( true )
{
buf[ bufloc ] = Serial.Read();
if ( buf[ bufloc ] == 13 ) // CR EOL
{
sscanf( buf, "%s %i", cmd, ¶m );
if ( !strcmp( cmd, "LED" ) ) // if cmd == "LED"
DoLed( param );
Glad it helped. Though as a longtime hardware serial interface user, I DO
strongly suggest going the ascii route. That Arduino function should work
as-is (with the bug fixes). Couple it with really simple code on the LC side
and you're done.
write ("LED" && tValue & CR) to file thePort

As long as you have DoLed( int ) and DoBeep( int ) functions, that looks
right to me now. It should be clear how to modify that to your needs, and if
not, feel free to contact me off-list and I'll give you a hand. :)

I had that problem when I was bringing up the MakeBoard as well. I was

Hi tom,
I am working with the same. What I undersrtand and have found on forums etc
you need to use atoi() to convert from type char to int.
You send out 3 chars when sending for instance, 125.
The arduino seial.read routine will fetch 3 chars (125)
I use a startChar 1 or more data chars and then
Mark,
I know what you mean. I spend so much time, sometimes, tracking down a problem
in my code that I just want to join the army and charge up a hill screaming
"Kill, kill, kill" until someone jumps up and shoots me in the shoulder and the
force of the shot spins me around and now I'm falling
Claudi,
What is your atoi() code like? Why tDataStr[8] ? is that the number of chars
you can read in? can that be more?
What if we want to send "<13-125>" can we parse that to separate out the 13 for
Pin 13 and the 125 for brightness?
What about "<13-1-125>" and "<13-0-1>" for pin 13 output 12

I'm not a real big fan of the "muscular morons," but it might improve
your opinion of Sylvester Stallone if you were aware that he not only

Yeah, yeah, that's all certainly possible.
At last I am getting somewhere, a relaiable connection and communication with
the arduino with all kinds of data.

Sorry for the wrong link I posted yesterday night. ( the arduino scetch instead

Tom,
There defenitly is hope. We can win that hill. It's also our's and we deserve
to be there.
It looks like I have assembled quite a stable setup. A kind of basic framework
which will first establish contact between
the arduino and LC and for both sides the routines to recieve and deciever
