Hi!

The question is just how to send and get data, , what interface I have to use to send and receive data from the sensor. The rest, like decoding data, CRC, I'll implement myself.

Cheers

Hello,

I recently bought a DS18B20 temperature sensor, but I got no idea how to connect it to Mizar32 and grab data from eLua. This is the datasheet:

Which interface I have to use, UART, some PWM pin??

Any help is appreciated ;)

Neither, you'd have to use 1-Wire (https://en.wikipedia.org/wiki/1-Wire). We don't have support in eLua  for that yet, although it should be relatively easy to implement.

Best,
Bogdan

Cheers
