digispark USB fun

Digispark doesn't allow using the normal Serial.println() that an arduino uses becuase it doesn't show up as a com port.

Instead you need to use hidapitester or https://github.com/Bluebie/digiusb.rb ruby app to read from USB data.

Digispark has VID/PID of 16C0/05DF

bluebie/digiusb

Start the digterm ruby app and enter 1 in the terminal. When 1 is pressed, the blue LED (pin 1) should turn on for 1/10 of a second

  • HKS0802A1U

Hardware

Option A:

  • USB to RS232 Adapter (Any should work, but I use this one )

Produces 360 images

This uses --animate which doesn't work with more than 3 frames when running in a docker container spuder/openscad-dockerhub#2

openscad /dev/null -D '$vpt = [0,0,0];' -D '$vpd = 20; $vpr = [0,$t * 360,0];' -o 'foo.png' -D 'cube([2,3,4]);' --imgsize=250,250 --animate 360 --colorscheme "Tomorrow Night"

The following all work, but not very well
