Hi everybody,
I am owning a CTC Prusa i3 diy printer for about 5 months now and its my first printer. I think it was the best decision to learn as much as possible about 3D printers. And I am modifying it heavily. I recently bought a new mainboard, the Trigorilla 14 Board, because I want to use the TMC2204 stepper drivers. The stock Anet A8 mainboard clone has fixed stepper Drivers, so I had to buy a new board to change the stepper drivers.
When I decided to buy the Trigorilla board (it's the same board, the Anycubic I3 Mega is using afaik), I made sure it is supporting my old Zonestar (LCD2004) display, which the printer is originally using. When I started to edit the firmware of the Trigorilla board, so that it mostly fits to my printer, i came along a problem. And because I am still quite new in terms of the firmware, I was not able to solve that problem on my own so far.
The description in "Configuration.h" tells me:
#define ZONESTAR_LCD // Requires ADC_KEYPAD_PIN to be assigned to an analog pin.
// This LCD is known to be susceptible to electrical interference
// which scrambles the display. Pressing any button clears it up.
// This is a LCD2004 display with 5 analog buttons.
And when I try to compile that sketch, an error about that "ADC_KEYPAD_PIN" occurs:
Arduino: 1.8.9 (Windows 10), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

OK, the Keypad pin has to be assigned to an analog pin. But I don't know, what the adc keypad pin itself is and I also don't know, what pins on my board are analog. And even if I knew it, I am not sure, how to saflefy change the pin assignment in pins_trigorilla_14.h, so that nothing is broken afterwards. And furthermore the ADC_KEYPAD_PIN doesn't even appear in the pins_trigorilla_14.h file.
The pins of the Trigorilla board can be seen in the following link:
Trigorilla 14 Pins
I would be very glad, if somebody could help me solving this problem. If any further information are needed, please ask and I do my best to provide it.
And I am sorry for my bad english.
Best regards
Hoast
