Re: [ts-7000] TS-7300, DIO & Keypa

["Don W. Carr" <>]

I don't thing the attachments work, so I will paste it in directly. This program has two modes, as either inputs or outputs. In the output mode, it flashes the outputs on and off every second. Don.

Hello All,

I've just spent the entire day trying to get the keypad to work on the
7300, and it still doesn't work.

The output lines on the DIO will not go LOW, they stay continuously
stay high. I can configure the DIO as inputs, and see the line toggle
when I pull it low. So I'm sure I've gotten it working the way you
expect in software.

I'm starting to wonder if I fried something on my board. Does anyone
have any working code for the keypad on the 7300. If so, could you
email it to me. Or if you can think of something else to try, reply
to the post.

Thanks
Jim Newton
