peteym5 Posted July 6, 2021 Report Share Posted July 6, 2021 Does anybody know how the driving controller is suppose to work in Atari 7800 Basic? I tried it, it seems like it is only reading going left. I am not sure this is suppose to read the Indy 500 controller, or some other type of steering wheel type device that plugs into the DB9 port.

RickR Posted July 6, 2021 Report Share Posted July 6, 2021 I'm not sure what the specifics of Atari 7800 are, but you have to write a "Gray code" interpreter for those driving controllers. If you're only reading one direction, I suspect you aren't polling often enough. https://en.wikipedia.org/wiki/Gray_code Quote Link to comment Share on other sites More sharing options...
peteym5 Posted July 7, 2021 Author Report Share Posted July 7, 2021 I suspect it might be an issue with 7800 Basic built in driving controller routine. I have written ML driving controller routines for the Atari 8-bit that I can just port over. Quote Link to comment Share on other sites More sharing options...
