I am currently doing a project wherein I have to display the information of a hardware matrix keypad on my computer screen. There will be a map on the screen resembling the keypad. Whenever a button is pressed the color of that particular virtual block in the map must be changed(eg. Green to Red). Hence if all buttons are pressed then all blocks must turn red. I am using PIC18f4550 for serial communication. I just want to know which software will be suitable for creating the map along with serial interfacing. Also I am a bit familiar with Matlab, so just wanted to know if this is possible using Matlab and how? Please do reply.
Thanking in advance

Hi, Have you considered using Visual Basic ?
I think VB will do.

you can use VB for Gui and serial communication
I understand that you want to represent more than on one pressed button at a time . so you have to use a bit mapping insede serial byte if the buttons are more than 8 then user a header of 255 value and map the other with 7 bits and end your message with 255 also. hope it helps
