I try to revive this topic ...
I found here (http://vnnik71.narod.ru/termo_ds18b20.html) schematic and hex file (even source code...) for an thermometer... It works absolutely great ! NO FLICKERING despite the absence of external quartz/HS oscillator !
How is made ?! I have no ideea ...
BUT ... in PBP this can be done ?!? I gave up to many LED display projects, because of this issue - annoying flickering ...
Know somebody a GOOD method to get a stable, sharp display ? Thanks in advance !
