starting program

tigershark35

I would like to start the program that is on my stamp homework board by turning on a power switch.

How can I do that. The reset button on the board is not accessable and I will not be connected to a computer. I can wire a button that is accessable.

Thanks.

When the power is applied to the homework board any program in the chip will start running.

I thought that was the way it was supposed to do, but it doesn't. It has a series of light that are supposed to go on and off but they don't until I push the button on the unit.

Ideas?· Could it be a software deal?

If you would attach your program people here can have a look at your code.

Stephen. good idea.

Here it is. Very simple test program. It won't do the counting until I push the button.

Try putting the PBasic 2.5 directive at the top of your code. When the directives are missing, strange things tend to happen.

TigerShark -

Is the green "Running" LED lit when you power up the Stamp board, or only after you press the RESET button? I presume the button you're speaking about is the RESET button on the Homework Board?

Just a passing comment - there is no reason for your variable "n" to be a WORD sized variable. Since it can only contain the values 1-8, making it a BYTE or NIB would be adequate. Additionally, I trust you realize the pin ports are numbered 0-15 and not 1-16.

Regards,
