#holtek — Public Fediverse posts

Something's wrong with the ESP32 based SNTP clock project I designed. This is the fourth display issue, this one worked for months and then went dead. I suspect the source of my HT16K33 display controller part, but I'll need to break out the oscilloscope to be sure. It's probably time to start working on the replacement project again. #maker #esp32 #time #clock #microcontroller #holtek #ht16k33

Trying to harness the #fediverse #electronics #hobbyist #brain ...

I've got a busted consumer product here that has 2 #Holtek #microcontrollers in it. Either one would be sufficient to run this product (a brushless-motor tower fan), but #MCUs are cheap, so why not throw a second one in if it saves a few centimeters of wire?

I'm trying to determine if there's a #standard #serial #physical #layer in use here to communicate from one #MCU to the other. It's one-way communication.
