futz f&ts v.i. To tinker experimentally; to change something just to see what it does

Wired up a 128x64 OLED display which uses the SSD1309 controller. Very similar to the SSD1306. I modified my 1306 code to work, and... No init. Tried tons of things until finally wiring up the reset line (this display pins it out - the 128x32 didn't) and writing a few lines of code to do the correct...

I have a bunch of various size SSD1306 OLED displays kicking around. I've always used them with downloaded drivers and told myself that "one of these days" I was going to dig through that datasheet and write a SSD1306 driver. Since I'm caught up with work and have some free time, and there is really...

So I ported some my old (working) MicroPython TM1637 code over to the Milk-V Duo and... it wouldn't work. Then, out of the blue, it worked, one time, and then never worked again. Very weird, because I could look at the output with the logic analyzer and it looked fine. Well... as fine as it's possib...

I spent the last few days doing my first real programming for the Milk-V Duo. I have one of Sparkfun's very nice LCD-16397 16x2 SerLCD - RGB Text displays, and wanted to get it working on the Milk-V Duo.

So I grabbed some PIC code for the display that I wrote a while back and ported it. Basically...

It's been a long break from electronics tinkering. Super busy year - all work and no play. I'm finally kind of caught up, cleaned off my bench and have some new toys to futz with.

First up is the Milk-V Duo board, based on the CVITEK CV1800B chip, which, if I understand correctly is two C906 p...
