Hello everyone, I'm new at this and am very lost. What I need is the following. When my mini2440 start we open a screen with 3 timers associated with 3 buttons on the board. When you press the button corresponding to any timer that comince to count, and if pressed again it stops. According to the 3 timers that has a box where you indicate the number of machine it is. These data do not have to delete ever, and from time to time that this program will connect via wifi to a computer to send data from the 3 timers and number of machine. If you can's take me a hand. Thank you very much.
