Hi, I try to program arduino sketch with bidirectional comunication between SAM3X and Android. I would like understand what are the analog and digital In/Out on the board. In my pov, I understand that : - Axx are Analog Input/Output - Dxx are Digital Input/Output - PWM are pulse digital signal Input/Output. Are you agree with this? Other question, When I manage Input/Output from SAM3x, how can I find the adress of each pin. For example : PWM13 -> addr : 13 (as we can see on tutorial) So you can define PinMode(13, OUTPUT). Now if I want define A0 to OutPut, is it correct to write : PinMode(A0, OUTPUT); I try to understand the following documents : http://udoo.org/download/files/pinout/UDOO_pinout_alternate_table.pdf http://udoo.org/download/files/pinout/Udoo_pinout_diagram.pdf Thanks for your help. Bye!
NO !!!! pin = ??; pinMode( pin , OUTPUT); and digitalWrite( pin, LOW); or digitalWrite( pin , LOW); The best way is to look at the examples , eg :- examples , basic , blink examples , analog , analoginput . - Axx are Analog Input/Output .. YES and NO , analog input or plane old input or output - Dxx are Digital Input/Output .. YES - PWM are pulse digital signal Input/Output .. pulse width modulation output , or plane old input or output
