AVR
This is an UNOFFICIAL AVR community.
This is a community for people who use AVR microcontrollers. This can include Arduinos, Arduino clones, Arduino like boards, and stand alone AVR chips and self-designed boards.
NOTE: If your circuit is doing something weird when you touch a wire or move your hand across it see this pinned post.
This is a community for everyone who is interested in AVRs and Arduinos from beginners to experts, kids to adults, hobbyists to engineers.

RULES:
-
All Lemmy.ca rules apply here.
-
Everyone (see rule 98) is welcome.
-
If you’ve seen a question 100 times answer it the 101st time or ignore it. Even better, write a complete, detailed answer and suggest that the mod(s) pin it to the community.
[Did you actually think there were 98 rules?]
-
If you present something as fact and are asked to provide proof or a source provide proof or a source. Proof must be from a reliable source. If you fail to provide proof or a source your post or comment may be removed.
-
Don’t be a dick. Yes, this is a catch-all rule.
-
The mod(s) have the final say.

For MIDI... I'm thinking AVR DB is the best of the new chips.
3x Rail to Rail op-amps, the signature of the AVR DB.
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.
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).
10-bit DAC -- You'll probably need to use one OpAmp to make this DAC usable as an output, but hey, its an option.
