Burning sketches on atmega644p using the arduino IDE

ShinranHL · August 6, 2016, 5:24am

Hello

I'm trying to use my atmega644p on an breadboard, first i burned the bootloader sanguino using my UNO as ISP conecting SCK, MISO, MOSI end the RESET if a 10uF capacitor to the ground and clicking on BURN BOOTLOADER and apparently worked.

My problem is that i can't upload any sketchs , i tried the blink example on the atmega644p using my UNO as ISP again and always says out of sync.

The arduino IDE can upload sketchs on the 644p or i need some burner like AVR USBasp to use the IDE? i already did this using atmega328 on an breadbord and worked.

Sorry for my english. KKKKK

Please list all the steps you took to do this.

I've never used ATmega644P but I use an ATmega1284P, which is very similar, all the time with no problems. I'm using MightyCore: GitHub - MCUdude/MightyCore: Arduino hardware package for ATmega1284, ATmega644, ATmega324, ATmega324PB, ATmega164, ATmega32, ATmega16 and ATmega8535. I think it's the best option for these chips.

You already have some problems with 3 party libraries ?

I tried to upload my sketch and only the adafruit_TFTLCD didnt work. I saw in the mightycore website that some libraries could not work.

Hi

I tried to upload my sketch through an UNO as ISP to my atmega644p, i'm using the MightyCOre library board and only the adafruit_TFTLCD library didnt work. I saw in the mightycore website that some libraries could not work.

Any one had some problems with 3 party libraries ?

Please do not cross-post. Threads merged.

Has your board uses external clock? If then you need an external crystal connected to xtal1 and 2, also a 22pf cap to ground.

You have to expect that sort of thing when you work with one of the non-standard microcontroller parts. A lot of libraries will work fine but others need code written specifically for each part and the authors just do the standard ATmega328p, ATmega168, ATmega32U4, ATmega2560. You can't blame them really because it's a huge job to try to add compatibility for every AVR. If you want an easy beginner friendly experience then just get one of the standard MCUs. If you want to stick with the ATmega644P then you have to be prepared to jump in to that library source code armed with a datasheet and make it work.

It's possible that people here could help you with getting it working but since you only posted a screenshot of a fragment of an error message it's obvious that you don't want any help. Good luck!

Wiring S board use ATmega 644p.

Have a look on Wiring project :

For your information arduino is a fork of Wiring project

Yes, i know that mics have diferent names for each register and that is the problem, i need help to change this ports in the library and i dont know where this configuration are because inside the folder has a lot of .h files like pinmagic.h , register.h and adafruit_TFTLCD.h, i have the Atmel studio installed to change the ports.

here is all the errors:

# MightyCore library porting
If you have used this core for a while, you might have discovered that some 3rd party libraries don't work with these microcontrollers. 
The ATmega8535, ATmega16 and ATmega32 are particularly vulnerable, while the newer generation (ATmega164, ATmega324, ATmega644 and ATmega1284) mostly work without modifications. Here's why: </br>

According to the [AVR505 Application note](http://www.atmel.com/Images/doc8001.pdf) which was released in 2006, the ATmega164/324 (as well as 644/1284) are new and enhanced versions of the ATmega16/32.
They feature lower power consumption, lower operating voltages and an extra USART port, but also different register names. These names are the ones that break compatibility.
While the new generation (ATmega164/324/644/1284) share the same register names as the ATmega168/328, the "old" generation (ATmega8535/16/32) share the same register names as the ATmega8. </br>
Just remember that the ATmega8535/16/32 doesn't have more than 4 PWM outputs and no pin change interrupt (PCINT), so some libraries will never work. Since PCINT is not present, the SoftwareSerial Rx pin can only be one of the pins that support interupts (INT0, INT1 or INT2). The Tx pin however can be any pin you like.

<b>Here's how to port a library</b>
* Download your library and open the header file (the one that ends with *.h)
* Copy the code below and paste it in the first line of the header file.
* Save and close. <b>The library should now be working!</b>

<b>Why am I still getting an error message?</b>
* The library is using a PWM pin that's not supported. Only digital pins 3, 12, 13 and 15 support PWM on ATmega8535/16/32 (using the standard pinout)
* The library relies on pin change interrupt (which the ATmega8535/16/32 doesn't support)
* You haven't pasted the code in the correct header file

Please don't post screenshots of error messages. Do you see that button on the right side of the orange bar that says "Copy error message"? Click on that button and then paste the output here on the forum using code tags(</> button on the toolbar). If the text is longer than the forum will allow then attach a text file. In this case you could turn off verbose output during compilation since the error messages give enough information. If you're smart enough to work with an ATmega644P you should know that posting pictures of words is not conducive to getting assistance.

You would also want to post a link to where you downloaded the library so we don't have to go hunting around for it. Help us to help you.
