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

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...

Today's tiny project was to add a display for the temperature and humidity instead of printing it to the console. I added another toy from the recent buy - a 1.3" OLED display.

I'm using the robert-hh SH1106 driver. Too lazy to write one for now.

The display's i2c address is $3c, so it works...

Universal-Solder had a year end sale. Couldn't resist grabbing a small pile of toys. One of the devices I bought was an Asair AHT21B temperature and humidity sensor. Asair says, "AHT21 is equipped with a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor e...

On my last post I had barely scratched the surface of what the LP55231 could do and was reading about the three program execution engines. After a bit of research I found that TI supplies a dashboard program and an assembler for the chip, but only for their own LP55231SQEVM evaluation board.

The...
