My module only has up to pin d8?

[joeybab3]

How might i go about connecting clock and data when my module only goes up to d8?

Im sure you have long since fixed this, but Wemos and NodeMCU boards are label the pins different to the base ESP8266 pins

See the pin out here https://www.wemos.cc/product/d1-mini.html

CLK is D5 CS is whatever you want (I used D3) DIN is D7

I'm having trouble with this, too. Using a D1 mini with its LED matrix shield.

From what I can see here, and here, the pins should match. D5 is CLK (GPIO13 in this library), D7 is DIN (GPIO14 in this library).

Tried the example but can't make it work, all i can see is garbled text

I did end up Fixing it, ill go back and see what i did

[joeybab3]

Yes, it goes: D7->DIN D5->CLK D4->CS And the code should work

Thank you for your answer after all this time.

Setting CS as D4 will actually blink the embedded LED on the wemos!

Here's my code:

#include <cp437font.h>
#include <LedMatrix.h>
#include <SPI.h>

#define NUMBER_OF_DEVICES 1
#define CS_PIN D4
LedMatrix ledMatrix = LedMatrix(NUMBER_OF_DEVICES, CS_PIN);

void setup() {
  Serial.begin(115200); // For debugging output
  Serial.println("begin");
  ledMatrix.init();
  ledMatrix.setIntensity(10); // range is 0-15
  ledMatrix.setText("A");
}

void loop() {
  ledMatrix.clear();
  ledMatrix.scrollTextLeft();
  ledMatrix.drawText();
  ledMatrix.commit(); // commit transfers the byte buffer to the displays
  delay(200);
}

I can't figure out what's wrong and right now, actually, I can't even see the garbled text anymore. No output at all.
