To make a digispark boot into your app without the 5s bootup delay follow these instructions. If you need to (re)program the digispark, just shorten P5 to GND. I’m using a digispark as a speed controller for my grbl based cnc router. With the standard 5s boot delay, the ESC’s signal detection window was missed… Read More »
So the same issue hit me twice: the on-chip, programmable pullups are only reliably doing their work if the environment is clean: electrical noise from steppers triggered interrupts the zener diode on the pwm1b pin4 of a digistump made it float around Adding 10k/4k7 pullups and 33n debounce caps did the trick.
Added (semitransparent) topology as map overlay (Rss-icon / map / Topo overlay) to GeoFeeder . This adds a 3D/relief look to the map.
