Definition of pins for the SPI #49

Closed mkhornet closed 3 years ago

mkhornet commented 3 years ago

Hi! I am trying to use this lib with my new display over SPI. Somehow after digging through the examples or documentation I cannot understand the how are the hardware pins defined (in this call: DisplaySH1106_128x64_SPI display(3,{-1, 4, 5, 0,-1,-1}); // Use this line for Atmega328p (3=RST, 4=CE, 5=D/C) I assume there are pin numbers in here but what is the layout of this command (the documentation is unclear for me about this matter) BR

Yes, I have found those but that is exactly what i don't understand. You write there as if there are only RST DC and CE pins needed for displaying when using something like arduino. I leave MOSI and CS pins open but I can't get it to work on 3 pins only. I have tested it with other libs (adafruit for SSD1306) and the screen in working.

All supported displays are verified. So particular the problem is in your specific case. You need to provide much more details: platform, ide being used, hardware schematics, code example, etc. Next, you're saying "adafruit for ssd1306", and the constructor is for sh1106. The description of the problem is very confusing.

Sorry if I am confusing you. I have mentioned the ssd1306 only because that was the first lib i tested (with adafruit lib) that confirmed my screen works. The screen I am using is using the sh1106 (at least that is what the manufacturers page says). The platform i am using is arduino nano clone and IDE is arduino IDE 1.8.13. The code I am using is one of examples loaded with your library. for HW connections: D3 ->RST D4->CLK and D5 ->DC

Ok, I'm a potato. Got this solved, I missunderstood the pin assignment. Thanks for the support anyways!
