Great to find an AVR community here! Let’s get some good content going. I used to work on some homebrew AVR-based projects (not Arduino, raw atmel ASM/winavr-gcc). I am reviving one project slowly…

Currently enjoying learning KiCAD, to move away from EagleCAD.

Anyone else working on MIDI-related projects?

    Honestly, I have just gotten back to it after a few years… the projects I am resuming were atmega8, but now I want to try the 88a, as it uses way less current and it looks like I can run at 4-8mhz on just MIDI bus power, yay no battery!

    I will look into the families you mention, I am waaay out of date :)

      For MIDI… I’m thinking AVR DB is the best of the new chips.

      1. 3x Rail to Rail op-amps, the signature of the AVR DB.

      2. Multi-voltage I/O – Port C runs on a second power supply, meaning you can mix 3.3V (main power, for portA, PortD, etc. etc.) and then 5V on PortC. Basically an integrated level-shifter.

      3. Full 24MHz speed at 1.8V – No more looking at charts to figure out what speed you can go. 24MHz is always available (true on all DA / DB / DD and EA chips).

      4. 10-bit DAC – You’ll probably need to use one OpAmp to make this DAC usable as an output, but hey, its an option.
