Hi, What is easy vary to convert Atmel program to Arduino ?
October 1, 2016 at 11:55 am #13045Ligo GeorgeKeymasterWhich is the compiler you are using for Atmel ?
Arduino has a separate compiler. You might need to manually convert the program.
October 1, 2016 at 10:18 pm #13047heat_z0neParticipantI am using Arduino 1.6.10 , i think its latest version.
I have Atmel 8MHz code for cable tester and pin used are ADC0( PA0) to ADC7(PA7) as analog pin and PC0 to PC7 as digital pin.
If i want to use same program for Arduino mega 16Mhz with A8 to A15 analog pin and 42 to 49 ad Digital Pin.
My question is what i have to change to get it work on Arduino Mega.
Here is code:
#include <avr/io.h> #include <util/delay.h> #include <stdio.h> #include <stdlib.h> #include <stdbool.h> #include <math.h> #include <avr/pgmspace.h> #include "hd44780.h" // LCD #include "lan_tester.h" #define F_CPU 16000000UL //8 //---------------------------------------------------------------- float GetADCData (uchar nChannel) { ADCSRA = 0;

October 2, 2016 at 1:52 pm #13048Ligo GeorgeKeymasterYour code seems to be based on Atmel Studio, so you need to manually convert the entire code for Arduino.
October 3, 2016 at 10:18 am #13049heat_z0neParticipantIs there any simple way??
I am not expert (*~*)
October 6, 2016 at 10:51 am #13050Ligo GeorgeKeymasterI don’t think there will be simple way for that. You need to manually convert it.
