Re: Temp sensor DS18B20 on STM32 sometimes read 85

Re: ST72681 usb 2.0 high-speed 8-bit mcu flash drive controller
during my googling i stumbled into this rather odd sku (apparently from ST) http://www.bdtic.com/ST/ST72681.html https://www.arrow.com/en/products/st72681r21/stmicroelectronics You found the ST7 MCU family, about 2000-2005 era. There was also ST9 family and ST6, I used them many many years ago in a...

Re: NTPClient_Generic Library to get time from NTP servers
+1!!!
Though ESP8266 and ESP have NTP syncronization in their core with timezone and daylight saving time too.

Re: STM8
I played with these cheap chinese STM8 boards some years ago with sduino
https://tenbaht.github.io/sduino/
that was the only core similar to the Arduino one before the new official ST core.
I translated to it an RGB lamp sketch, I used an Attiny86 too!
