In Topic: Multiplexing 7-Seg Display

Stefan - Thats what my preliminary code is doing basically, but I'm not multiplexing yet. I'm worried about getting similar results to ggergely with flickering. Maybe this won't be an issue? Thanks for that link, though, thats EXACTLY what I was looking for!!
Mario - thanks for the info! I hadn't really considered that. I'm not terribly concerned with accuracy.
The project is actually a Rolling Ball Machine (inspired by this guy http://www.brucegray...ollingball.html ). I am triggering the marble run to occur on the hour.

Thread.Sleep(x) takes the argument as milli-seconds. What's your problem?
I just feel like there has to be an easier way to combine multiplexing portion with the counting than doing a sleep on the thread for 250 MS, writing the MINUTE variable to the 7 segs, then each 4th run increments the SECOND variable., and min & hrs appropriately.
I guess my question is, if i put the sleep to wait until the next second, how to i get my muliplexing to work??

Chris,
So if I understand this correctly, I would need to do the following:
1. Use the Netduino schematics to build a duplicate board for the USB to IC circuitry. I/O Ports, LEDs, etc would not be needed.
2. Have a breadboard insert or some sort of ZIF socket to insert the Atmel IC. This links the pins of the Atmel chip to the proper pins of the USB interface. This creates basically a new netduino, minus the cool packaging, I/O, LEDs, etc.
3. Use the SAM-BA procedures to flash the chip with the desired program.
Is this correct?

Chris,
Thanks a lot for the information. Do you have a fast-flash programmer that you recommend? Looking for something on a budget (i.e., cheapest I can get by with).
Also thanks for the tip on the chips.
