After I replicated @BatchDrake I2C over coax setup (mastodon.radio/@jeffpc/1094252), I wondered if the 's outputs are weak. Tonight, I finally got a few minutes to try out a similar thing on a . I fed the SPI clock output through the same 30.5m coax. It looks quite good!

This time, the setup was a bit different, the connections were:

AVR -> ~1m long coax -> T adapter to channel 3 (cyan) -> long coax -> T adapter to channel 4 (green) -> 30dB attenuator as a 50ohm load

Just discovered Enhanced Music Controller.
It finally allows me to control my Pioneer A/V receiver without their buggy app 👏

Since still haven't got around to shipping any non-absolutely-ancient `avr-libc` files, I've written another "reminder to self" blog post about how to build for the new ATtiny 2-series chips, as a followup to my previous 1-series one.

A driver for an ST7735 colour TFT display running on an microcontroller. What's great about mine is that I can read values back from the display, by putting the SPI controller into hiZ output to read the bizarre half-duplex IO mode this display chip uses.
(The actual colours on the display look much nicer to the eye than my phone camera can pick up)

I have two questions and I'm hoping to find one or two folks who can answer them before I make an account on the AVR forum.

First, how does one load a byte from a pointer and increment that pointer? Here's a few screenshots to show what I'm doing.

I've been building a MAX7221-inspired -powered code to drive up to 16 7-segment digit display. For whatever reason, it was trying to display N-1 blanks and a "0" as the first digit when fed with valid input. After several evenings of debugging, I realized that I had the SDI wire hooked up to the wrong pin on the . *facepalm* Moving the wire to the correct place made everything work.

I though I’d learn code and programming at the same time. I started with an ATmega48P gating a 555 generating a tone. But that’s boring. So, I extended my code to generate messages toggling D#6 on and off.

OK. Conjecture: Apple will have some fairly tight integration between their A/VR headset, Apple Watch and Apple Pencil. If it doesn’t, I’ll be disappointed. Both the watch and pencil are unique to Apple. Anyone can do AVR.

Will we get a SightKit?

Blinky and UART TX on the ATtiny414. Cute processor in an SOIC-14 package and runs at 20 MHz. It requires only VCC and GND to run. Programming occurs via the RESET/UPDI pin. I use JTAG2UPDI from github on an Arduino Nano as programmer. Unfortunately, AVR-GCC does not have the headers or libc for this uC by default.
