Report Can't implement GADC in Support Posted February 3 I did it. I found that the ADC values should be passed as a parameter "rawvalue" to the function DialCallback(gU16 instance, gU16 rawvalue) called by poll timer. Dial attached to sliders works ok. From ADC as well as from encoder. Now new question. May be not for this topic. How to do text string controlled by dial? Something like frequency readout. I think there is only one way. This is Label. But label can not be attached to simple variable in memory as dial and toggle to objects. Maybe there is an elegant way to do this?
