GLCD_OLED_FONT = 1 this reads the tables called OLEDFont1Index and OLEDFont1Data. Replacing this is one way.

I am still trying to grab this method. Hope to get success.

Two devices as above arrived today. There is no DO- lines on the display are
gnd, vcc, clk, cs, din
using hardware spi didn't work.
I wired a display and print or scroll chars go from display 1 to display 3, 2 to 4.
using the demos.
the thread is Using GCB with Generic MAX7219 Module and Arduino Nano.
I wonder how generic my displays are, I bought 2...only £3.50.
I will see the include for a clue. https://youtu.be/3iNgVcDLKIU

The include looks complicated imho.
Is Sub Max7219_LED4Matrix_SendBuffer the part that send to each display?
case 1 to 8
case 9 to 16
case 17 to 24
case 25 to 32
edit no
hows it work? is there a a memory matrix of bytes and each byte's a row of leds, ie bit per led ?
what does Max7219_LEDMatrix_Update do I'm looking at. Difficult because no idea how spi works.
So no idea what DOUT is for.
£3.50 for 4 displays joined is nice. You can pay twice that for one. Worth supporting ephemeral Chinese clones?
That is not way I would do it. As I am not guess.
