Instructions | Onion Omega Carputer

1

Step 1

Identify GPIOs to use on the Onion
2

Step 2

For Inputs develop an interface suitable for the signals to read, keep in mind Onion only reads digital inputs
3

Step 3

For outputs identify if PWM is needed, beware of maximum current to handle, relay may be more convenient than solid state devices.
4

Step 4

Initialize inputs and outputs in the bash script (in this case) at the begining.
5

Step 5

Debug reading inputs and setting an output
6

Step 6

Dive under the in-panel fishing for the correct signals to read and activate
7

Step 7

Connect experimental I/Os by twisting the wires until the set up is confirmed to work.
8

Step 8

Solder and tie wires, relays, transistors so that components won't rattle or fly during usage
9

Step 9

For specific Open Doors, Close Doors, Starter functions. Put the Bash scripts under /www/cgi-bin/* and call them from any browser with 192.168.3.1/cgi-bin/Script.cgi
10

Step 10

Debug with a terminal and ssh
