Hi,

I just finished a project interfacing the Sony control stick. It's a very simple design, only three small components! (not including connectors)

Nice one, simple beyond belief! A couple of points to note: -

You may have problems with this design over the automotive temperature range, the RS232 timings may be a problem using the IRC, RS232 (from memory) about 5% tolerant on timing, the IRC over it's range is about +10/-15%, the unit may fail to communicate in extreme hot & cold conditions. The R/C timing ADC method may fall over again with temperature, capacitor selection, noise are all issues to be wary of. Still, a good low-cost solution that's cheap and easy to construct, well done.


Regards,
