Any one know how my program should be like when i need to pass in information for example "a" and display it in a display box... through serial communication.
none of my beeswax, but what does this have to do with Keil software? Are there no websites for PC programming. so, 1) this is not the place and 2) the right place will, probably, have more answers. Erik
"Are there no websites for PC programming." For all Microsoft development issues, your first port of call should be the MS Developer Network, MSDN: http://msdn.microsoft.com/
