A brief description of how to edit the code for the Fly Screen Firmware.
Code File Location
The main code file can be found in jni/logic/gcodeLogic.cc. Double clicking the file in the IDE will open it up.
There are different timers available to denote how often something is queried. Each one is in milliseconds.
On the below example, the ID is set to 0. ID 0, as shown above, is ran every 1000ms or 1s. The serial port is used every second to send M408 to the firmware.
