Lets start with something simple like "1234" Assuming the data from the Arduio code is right, then the 8-bit data for the numbers would be: "1"=&H60, "2"=&HDA, "3"=&HF2 and "4"=&H66. How do I combine those bytes in the correct way, to generate the 32-bit word to send? Smoke makes things work. When the smoke gets out, it stops!
