Quick solution for use some ATmega microcontrollers in newer Arduino IDE ver. 1.6.4
As we know, recent changes in the Arduino world have boosted development of Arduino IDE, now reached version 1.6.4.
I do not want to talk at all of the war Arduino LLC vs Arduino SRL (not now, not here). In fact I think my opinion on this topic is not important.
So, I downloaded and try versions 1.6.2/1.6.4 from Arduino.cc and 1.7.2 from Arduino.org (1.7.3 not tested yet).
And I decided to go ahead with 1.6.4 from Arduino.cc / Arduino LLC http://www.arduino.cc/en/Main/Software.
I took the opportunity and did some cleaning in the files pins_arduino.h for ATmega1284, ATmega32 and ATmega16. I remove defines for A0-A7. We can access all 32 digital pins with digitalRead(0 ... 31) / digitalWrite (0 ... 31,[...]) and ADC pins with analogRead(0..7).
Step 1: Select Preferences
Select Preferences from File menu.
Edit Additional Boards Manager URLs field and put this link:
Step 3: Open Board Manager
And wait a little...
Step 4: Install Boards
Yes it is easier now.
Step 5: Done
Now it's done. Almost :)
For ATmega1284 any change is no longer necessary.
For ATmega32 and ATmega16 we need to edit
we will replace:
#if defined(__AVR_ATmega8__) config |= 0x80; // select UCSRC register (shared with UBRRH) #endif
#if defined(__AVR_ATmega8__) || defined(__AVR_ATmega32__) || defined(__AVR_ATmega16__) config |= 0x80; // select UCSRC register (shared with UBRRH) #endif
Step 6: Finally
Please note: This is a project in progress. It may have some errors. I tested compiling and uploading some examples for ATmega1284/32/16.
At this moment are defined six "boards"(usually I work with these microcontrollers.):
I intend to include ATmega644 and ATmega1284P, but it will take some time (I have no one handy). I plan to buy two of every and and put them on these small boards like above.
