I am having trouble accessing an Arduino Uno attached to my computer via USB.
The device driver shows up as "/dev/tty.usbmodem1a21"
I tried a simple open driver then read from driver then close driver. But
Livecode keeps crashing or worse my computer panics and dies.
on mouseUp
put "" into field "IOresult"
open driver "/dev/tty.usbmodem1a21" for binary read // tried text read,
text update, binary update
wait 50
read from driver "/dev/tty.usbmodem1a21" for 1 line in 4 second // tried
for 3 char in 3 seconds, tried until eof
if it is not "" then
put "it: " & it into field "IOresult"
else
put "result: " & the result into field "IOresult"
end if
wait 50
close driver "/dev/tty.usbmodem1a21"
end mouseUp
I just want to read data that is being sent from the board. In Arduino there is
a serial monitor which does read the data coming from the board. It is a bunch
of numbers one per line as in 1023 then 992 then 992 etc.
I can't seem to figure out what I am doing wrong. This seems pretty straight
forward.
I sent an email to Mark Weider but then thought that others might also have
ideas.
Thanks
