Re: Temp sensor DS18B20 on STM32 sometimes read 85

From https://forum.arduino.cc/index.php?topic=201863.msg1488781#msg1488781 There is a footnote on page 4 which says "The power-on reset value of the temperature register is +85°C." so if you read 85 degrees it means it hasn't done a conversion since the last power on. You hadn't wired it u...

Re: STM8

I played with these cheap chinese STM8 boards some years ago with sduino

I translated to it an RGB lamp sketch, I used an Attiny86 too!
