Howdy, trying to get the Circular LED (LED01113P) to work on a Mega. I tried the example sketch, it did not work (I changed the port numbers for circularLED1 to 2,3 3,2 and tried 4,5 and 5,4 as well.)
I thought this device was I2C but it looks like the library is bypassing the Wire library and sending data straight through to the ports. Does this mean only certain ports will work for a library? Can I use the device with the Wire library? If so, what is the address of the device??
UPDATE: Found the MY9221 data sheet. Oh dear, not I2C at all. Some serious bit-twiddling here, need to understand portOutputRegister, etc.
