·I want to run a led display board with a BS2 Stamp and a Max6552 Matrix Display Driver. I·am new to programing the stamp, the Shiftout and Shiftin· commands should work, but do not know how to set it up. Has anyone done this and have a sample program that·I can use to get started.

HC9494,

· While I have not used this particular chip, I imagine communication may be similar to the MAX7219 which has a lot of example code for. You may be able to use the code for the MAX7219 to help you out. Let us know if that is any help if nobody else posts example code. Also linking to the datasheet may help others to analyze the data.· Take care.

I was able to get somthing to work through the help of Don Jackson ( R4 Systems) and the people from Labcenter Makers of Proteus7. It turns out need to do the following sequence

1) specify intensities
2) specify characters
3) specify configuration
