Liudr,
I recently purchase 3 of your serial backpacks from your iNMOJO store.
I have mounted the backpack on to a 20x4 LCD display.
I have learned how to use Xloader to upload hex files to the serial backpack.
Currently, I have the phi_panel_20x4_panel_1_6_2.hex firmware loaded.
I have run the phi_panel_big_show_NSS.pde
Everything works fine except instead of the 4x4 keypad interface I wish to use a
Rotary encoder.
Can you provide or point me to the correct firmware that supports a rotary encoder?
Regards,
