Is there a guide somewhere how to enable 1wire support on a rock64 using stretch or xenial.   Im trying to read a dallas DS18b20 sensor.

 

I see some examples for other boards but cant figure out how to apply them to the Rock64.

Thanks

If you want reliable, go for a 1wire to i2c bridge like the ds2482 or something.

 

Bit banging timing sensitive protocols in a multi user OS is never a good idea. It wastes CPU time with spin waits and if the process gets pre-empted it will probably fail.

Thanks!  I'll get some and check it out.   Apperciate the help!

 

It then gives you the freedom of using a w1 kernel driver or doing it all in userspace.

Being i2c, it's a master clocked protocol, so there are no timing issues even if you don't have a hardware i2c port available.

OWFS supports the Maxim i2c chips too
