Handling a steering wheel (analog input) #9

Open cyllboy opened 4 years ago

cyllboy commented 4 years ago

Could you please point me to an example of how to handle an analog input (eg. steering wheel)? Is there any example I could look at to learn? Thank you very much!

In this iona.ino configuration, iona reports 8 channels of analog inputs supports around the line 199. Once the host, e.g. naomi, recognize this report, it will start asking kCmdAnalogInput to retrieve the analog input status. The command is handled around the line 233 in the iona.ino.

Currently, it simply returns [0x80, 0x00] for each analog input channel, and this represents the center position in unsigned 16-bits integer.

If you have additional code to get analog inputs from e.g. USB gamepad, you can pass the value from your managed controller here. You may need to investigate which channel of analog inputs used for the function you are interested in.

Great! Thanks a lot for the explanation!
