I’m glad to announce that the annoying watchdog issue has finally been fixed. It was a dumb error on my side, combined with a prevalence in some ATmega chips to have certain binary values in uninitialized registers after a cold start.
release 1.44
* Fixed “.init1” mistake –> watchdog_off_early.
Putting that into .init1 doesn’t work, as it requires R1 to be ZERO.
“eor R1,R1” comes later, so it blows up.
V1.44 release on Github.
Hello! Do you have any informations on the hot air handle with all of these wires coming out? Like the ones sold as replacement, i would like to build one with arduino, but i don’t have idea on the wirings, which temp sensor uses voltages etc!
Not really. The best starting point might be the schematic. It is in the firmware repo on github.
