mcudude / butterflycore Goto Github PK

If possible..
Please Add optiboot enable/disable.
Like MegaCore.
I want to Use Atmega329P with No Bootloader.
And free some bytes of flash memory.
Thansk.

In the description it says rtc support but I can't find any example or library for the rtc of the butterfly.

I've been spending a lot of time polishing on the Butterfly specific libraries such as LCD and temperature.

The ATmega169 (and the rest of its family) has actually two different device signatures. the ATmega169P/PA/V has one signature, and the ATmega169/A has another one. the problem is that the original avrdude.conf file only has one option; atmega169, which actually has the P/PA/V device signature rather than the 169/A.

To solve this I've added a modified conf file. The problem is that when you're uploading the code using a programmer (shift + upload), Arduino IDE refuses to use the modified conf file. I've tried everything, but I can't figure it out. I've attached the current core as a ZIP file.

Hello!

First of all - thanks for this great Arduino Core!

I have LCD which is 1/3 bias and 1/4 duty. It has only two digits (8 pins in total, 4 common pins and 4 segment pins).
I would like to try to use this LCD with ATmega329P. So I connected all four common pins to ATmega329P COM0...COM3 and also segment pins to SEG0...SEG3.

Now, questions:

1. where and how I can define which segments belong to which pins?
2. I have 16 MHz external crystal connected to ATmega329P - will it work with LCD? Everywhere is mentioned 32,768 kHz crystal, but not 16 MHz.

I search it ,but unfortunately no effort...or how can i use it in Arduino IDE
