Analog-to-Digital Converter Code

I'm an experienced embedded programmer, but new to the IFI hardware.

I tried deploying your gyro code on the small EDU controller. I discovered that when I included the new ADC module I got a program run error light, so I dropped back to the standard iti_utilities code for the ADC conversion. (I assumed a basic hardware incompatibility....)

My only problem is that now I'm not sure where to put the call to Process_Gyro_Data().

I'd like to put it in User_Routines_Fast.c but I don't have your ADC code installed so I don't know when the converters have got new values. D'oh.

Am I flogging a dead horse here, or is there a simple way to use the standard IFI analog utilities to drive your Gyro code? I'm only using a single analog channel (for the Gyro) so that may simplify things. I don't need fully calibrated data for my initial testing... I just need it to basically run. If I can get the calls IN, I can get the rest to work.

Thanks for your time.
Phil.

Phil,

Gyro code for the EDU-RC can be found on my website.
