While trying (and failing) to fall asleep last night I may have found a way to make one of the megaAVR timers do double duty - not at the same time but at least serving two masters.

I need to revisit how timers are used by my IR code first … yeah, I’ve already forgotten how my own code works 🫣
bradanlane.bsky.social Bradán Lane @bradanlane.bsky.social · Dec 29
I find it very odd (not in a good way) that the ATtiny16* has three timers (TCA, TCB, TCD) but the AVR64* has only TCA and TCD. (I'm leaving out the RTC and it has speed limits).

This may not be important for some projects but my IR designs need three different timers 🙁

Found this great image of the first #AVR #proto. This is the ancestor of the ATmega tinyAVR, megaAVR, and AVR Dx chips so popular amongst #makers and hardware #hackers.

Of course, I turned it into a shirt design. One with proto front and back on front and back of shirt. Also one with both in front.
Hand holding front view of the first AVR proto board, showing chip, resistors, battery holder, button, and four LEDs Hand holding back view of the first AVR proto board, showing traces and some identifying text. Hand-illustrated white line stylization of the front (on top) and back (on bottom) of the first AVR pronto board, with blaze orange highlights for the LEDm traces, and identifying text.
