@ Joe Thanks for the pointer to source code. I’m trying that now, but nothing is displaying on my LED Matrix. There are 6 pins on the SPI Input interface, as follows:
VCC = I have this hooked to 5 volt.
CS = I have this hooked to Digital Input 1.
GND = I have this hooked to ground.
I’ve got the following code running in my Main method:
using ( var spiBus =
new SPI(new SPI.Configuration(Cpu.Pin.GPIO_NONE, false, 0, 0, false, false, 1000,
var panel1 = new SparkfunLEDMatrix((Cpu.Pin)FEZ_Pin.Digital.Di1, spiBus);
for (var i = 0; i < numbersBitmap.Length; i++)
Debug.Print(i + ": " + numbersBitmap[i].Length);
if (i >= numbersBitmap.Length - 1) i = 0; // Display 0, 1, 2 forever
Any ideas why nothing is showing? I know the LED Matrix is good because when I unplug then replug the ground wire, it flashes.
