Looking to Make a Simple Controller to Navigate Display Menu (FPS, ISO, Shutter, etc)

[Jamie A]

I'm looking to make a simple controller to do the following serial commands on DSMC2:

KEY_ACTION_NAVIGATION_CW
KEY_ACTION_NAVIGATION_CCW
KEY_ACTION_NAVIGATION_SELECT

Basically to go left & right through the on screen menu & have the select button.

I'm thinking of using an Arduino or Teensy controller with 3 or 4 buttons to send the commands to the camera.

I feel confident with the hardware build but am somewhat new to the programming side.

Does anyone know if these commands are still valid and how to program an Arduino or Teensy to send these commands?

Many thanks...
