rotary encoder usb audio volume control
Posted: Mon Dec 26, 2016 10:59 am
We are planning to start a project for rotary encoder volume control on the xmos usb audio to replace the default HID button volume control(tough and hard to use).
I need to know if xmos also have plan or is already working on something similar to avoid duplicate work. The ADC VR volume control is a big surprise when I notes it few year ago.
It will make use of QEI code xmos develop for robotics three year ago(seems retired?), the latest comment from the xmos qei sample code:
QEI server algorithm now uses regular sampling of QEI ports (i.e. NOT triggered by change on port). This is more robust to QEI noise.
To detect rotary encoder change, SELECT should not be used? or no problem to use due to manual turning encoder is much slower than motor?
