Hardware > Connecting a RPM sensor to the link port

#11123 - Bad Mr Frosty - Fri Sep 26, 2003 6:07 pm

Hi,

Does anyone know of any technical documents that outline how the link port on the GBA works?

I basically want to connect a RPM sensor to it that would pulse on every revolution of a wheel then the GBA would read and act on this information. Does this sound feasable?

Does the port interupt on data recieved? Is it buffered?

So many questions, I hope someone can help out!

Many thanks

Start here.

You'll usually want to use "SIO UART mode" to communicate with devices not specifically designed for a GBA, as SIO UART mode uses a protocol that differs only from the popular RS232 in voltages used.

Nice one, I never knew the port was just a RS232. That will make life much easier!
