I just got 7 new 8x8 panels. I’m trying to get the Sample Arduino Sketch to work.
Input SPI
GND → GND
MOSI → 11 From Sketch: #define DATAOUT 11//MOSI
CS → 10 From Sketch: #define SLAVESELECT 10//ss (cs is alternative naming?)
SCLK → 13 From Sketch: #define SPICLOCK 13//sck
VCC
VCC → 5V
In the sketch I see, #define DATAIN 12//MISO
On the board MISO is on the male, Output SPI. I don’t see any of the pics talking about wiring to both ends of the backpack. Is that right?
Output SPI
GND
MISO → 12 From Sketch: #define DATAIN 12//MISO
CS
SLCK
VCC
VCC
I need to set that somewhere in the sketch?
Will I need to reprogram the backpacks to make the 7 work together?
Surely I’m missing something fundamental. I see on the schematics that the Input SPI and Output SPI label the MOSI and MISO backwards from how the printing on the board does.
Thanks for patients, trying to get far enough to figure it out.
