Is it possible to have the eQEP counter count more than a 16 bit number? If so, how do I set that up?

Hi Andrew,

Thank you for your inquiry. The position counter in the eQEP peripheral is a 32-bit counter. Where are you seeing the 16-bit value?

Regards,

Peter

It seems to roll over at count 65535.

Hi Andrew,

Can you verify the maxPosition value in your Position Counter configuration settings? I've attached screenshots of the function or GUI, depending on if you're using DriverLib or SysConfig.

The max configurable value is 4294967295, which is the maximum for a 32-bit unsigned integer.

Regards,

Peter
