Can it be easier? Just configure your I/O, make your FSM, connect a com port at 128k and get testing!
It is now possible to download the VBA debug application. You don't have to code the VBA application, just add the serial com port to the shortcut and start the application. Standard speed on 128K. The debug application will setup the communication with the board. The standard functionality is available for monitoring, forcing en masking I/O tags. Also the current state(s) of the FSM(s) are presented in a checked listbox together with the current cycle time, the free RAM on the board and the current time of the board. Funny!
