How to #7

Hi guys

I saw this library on Arduino and I wanted to know how do you make it work with Arduino Uno for example. Because I have the LedControl library which works perfectly but can't make this one work for me with all of the examples.

How should I connect my wires on the Arduino ?

"const uint8_t LEDMATRIX_CS_PIN = 9;"

I think that it doesn't work because of this line that I may have not configure properly.

Thank you

Hi,

From what I see it should be clock (SCK or CLK) to pin 13, DIN to pin 11 and then CS (SS) to wherever you choose (except for pin 10 and 12). 9 should be fine. Don't forget GND and 5V.

You can also try to lower SPI baudrate in the spi settings to something lower (like few hundred kHz). The default I use for ESP 8266 is 5 MHz and it could be too much for UNO.

Cheers, Bartosz

Thank you it works perfectly now. Problem was that CS was connected to pin 10 which was forbidden.

I'm glad it worked for you, cheers :)
