Basic LCD display question for you guys. Just got a Standard LCD 16x2 and followed the tutorial on Adafruit and on the Arduino site closely. Just trying to get the Hello World goin'. The potentiometer is working so that part of the wiring is a-ok.
I do get this error message when I try to upload (not every time..)
/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr/bin/avr-ar: wiring_digital.c.o: No such file or directory
Am I missing something?
I'd be happy to show a photo of my wiring but I was pretty attentive there. . Thanks
If you disconnect everything, will it upload reliably then ?. If it does, will the LCD work if you connect it back up once the sketch is loaded ? Most problems with LCDs are wiring related. A good picture of what you've got would be a big help. We don't have the benefit of having it in front of us.
I get that message occasionally. I simply save the code and then close and restart the Arduino software and everything works normally. Also check and see if the code will compile without uploading. Don't know why it happens.
Im also getting this kind of error time to time.
I clik Compile/Upload I get the error saying the Pin number is not in reference or something like that. Then I press the button again without changing anything and it work.
Ide v. 0020. one of the three annoying bug from that version. One got fix with 0021 (PWM) as for the others...
