Hi all!

Since upgrading to FC6. PIC + AVR I have in my eagerness to test the functionality dabbled a little with Arduino.

I made a small test program to Arduino uno + lcd keypad shield in FC 6.
Arduino Uno: http://arduino.cc/en/Main/arduinoBoardUno

The LCD keypad shield: http://www.miniinthebox.com/da/16-x-2-l ... 40888.html (randomly chosen page)

First, you need config compiler options, according to Ben's instructions: http://www.matrixtsl.com/mmforums/viewt ... 54&t=13084

There is a similar program to C + + for Arduino somewhere.
As you can see in the diagram consists keypad function of an analog input. The values determined by the resistor network. This way you get different values depending on which button you press. One input is many input on this way.

Maybe usefull

above is my old topic, ı tried everything but unsuccessful

Hi.

Are you using an Arduino Uno and arduino display/keypad (buttom) Shield ?

Maybe your Arduino or display are deffective. I guess. Have you tryed to add a 1 sec output flasher in your programm so you Can see that the controller is running.
Mine is working perfect.

arduino is running and even with arduino ide program, lcd keypad shield is working. in flowcode, arduino is work, but in flowcode ı could not do anything about lcd, not work lcd. ı can do control back light but write problem.
