8Mhz is recommended by the tooling and can be divided down to the required 2Mhz with the ADC prescaler

The qtouch configurator has changed the default output to not use the binding layer. Let's remove it to be more in sync with the configurator. No functionality is lost. All changes come from the new templates.
* Lower the ADC/PTC frequency to 2Mhz * Lower the analog gain as that introduces more noise * Higher analog gain of edge sensors that are less sensitive * Make filter 8x digital gain as per recommendation * Reduce threshold for active to 12 (to be tweaked) * Put sensor groups in AKS groups so that if one sensor is active no other sensor in the same group can become active. * Reduce hysteris to 25% to make "untouch" quicker * Speed up all calibration rates to 1 step per 200ms * Set a maximum touch time of 10s to eventually abort in case someone puts the device on a table * Remove force calibrate. The faster calibration rates should fix the sensors equally quick. * Add all functions from templates that was missing to make future diffs with atmel start smaller.

Commit qtouch: switch PTC to 8Mhz clock from 12 Mhz is changing a bunch of configs that seem unrelated to the PTC rate. Please explain them too in the commit msg. |

There was a problem hiding this comment.
rename scroller_active too, or keep the param name scrollerr, for consistency?
It is all related, I enable and configure clock number 5 and I configure the ADC/PTC to use that new clock. |
