Ported Control Serial Display Via Commands. Uses Highest Speed BAUD Rate Possible. You can DRAW,TYPE Create Menus or whatever you like just by communicating with the mbed over serial connection. I did this a while back however Ian Uploaded most of the files i published a while back to his account.

Dependencies:   mbed

Everything should be working. If not start a discussion and i'll help you asap.

Here is some VB.NET code to help you get started playing with the tft screen through serial. This code will create a menu based graphics which you can select the menu on the left of the screen You can create your own in menu graphics and items however you like, and modify the code to make the mbed do anything you like from inside the windows vb.net application, All you will need is 6 buttons on the form.
