Hi Steve, I have display working on my tracker, currently running V4.5.5. My autopilot is Speedybee wing mini F405.
I built the custom firmware using the Custom Firmware Builder, in ‘‘Other’’ dropdown box I selected to include I2C Displays build option.
Then set NTF_DISPLAY_TYPE to sh1106 since that’s the type of display I use. What display are you using?
On another note, I wish the ‘ARMED!’ message on the display could be turned off, because it’s there all the time and ends up making the display feature useless.
There’s an open issue about that problem Notify: Add parameter to enable permanent parameters on onboard OLED display · Issue #18215 · ArduPilot/ardupilot · GitHub
