LCD does not work
LCD does not work for me, how to integrate a Telescope Display Unit? (RepRapDiscount Full Graphic Smart Controller with smart adapter)
I have the same problem. Wiring diagram has a mistake. 5v and gnd are not correctly depicted on the image. However, even with this correction the display does not show anything
hi alexscuer... i finally solved it by connecting the U8glib library and my own menu #ifdef LCD_ENABLED #include "U8glib.h" U8GLIB_ST7920_128X64_1X u8g(23, 17, 16); // SPI Com: SCK = en = 18, MOSI = rw = 16, CS = di = 17
Where are you adding this code @Despo71 ? In the dobson-star-tracker.ino ? I too had to do some readjustments of wiring the display, do you by chance have a picture of your wiring ? I have found GND and 5V so far.
If I get this running I might fork the repo and adjust the wiring as needed for anyone else who might encounter the same.
I have tried connecting to stellarium directly because the display seems impossible at this moment. Conecting to stellarium seems to work as the program shows a "conected" status. However the motors do no to move at all. In my humble opinion the shield is not correctly wired either, I think it must be placed on top of the arduino mega as this is how it is designed...
@atxbyea If you decide to fork the project please let us know. I will be willing to help
Forked it @alexescuer so I'll try to update with my current new findings as I have time going forward, please submit any PRs to my forked version and I can merge as needed.
@Despo71 if you can come back with what you have I can try to incorporate it in a fully working repo
The display still doesn't work, I added an encoder, nothing has changed. The author didn't even indicate the display on the diagram. I installed everything in the libraries, nothing has changed

This is the second Arduino board, the first for RAMPS. two boards are connected by only 2 wires). Now I'll try to upload a sketch for the display. Why an external power supply, without a USB connection, 2 arduinos. I'll write what happens.
