Display doesn't work #32

Closed SkromnyNick closed 6 years ago

SkromnyNick commented 6 years ago

Hi! My clock doesn't work. The whole or half screen is all time on. Sometimes it blinks. D1 Mini and screen work because everything is good using a different script (https://drive.google.com/file/d/1cBPUl9tztSOoEt1IL99C2vWOICdgKlcq/view) Can you help me?

The code you tested with is using totally different pins.

// MAX 7219 WEMOS
const byte CS = 0; // D3
const byte CLK = 4; // D2
const byte DIN = 2; // D4

YOU MUST use the pins in the documentation for the code or change the code to use the same pins you have wired up right now. Does that make sense?

I know that. I connect the display to such pins as in the picture (D5, D6, D7). Below I give the video the screen blinks. https://www.youtube.com/watch?v=TMr1prFPcI0

Not sure what to say. The only time I have seen that behavior is when it isn't wired up correctly. Can you give some details about the hardware you are using? Is it a Wemos D1 Mini?
