Ben Nizette 92c548cd35 favr32: improve touchscreen response ... The ezLCD+101 board (to which an favr-32 is fitted) has a long, unshielded, nasty lead between the touch panel and the ads7843 touch controller. In order to get satisfactory response then, we need to employ every noise-reduction trick in the driver's arsenal. After extensive fiddling I've found some good settings: 1) We keep vref on all the time to dramatically reduce settling times (at the cost of a tiny increase in power consumption). 2) Despite 1 the settling time is still non-zero. 500uS is plenty of time for the signals to settle 3) Despite 1 and 2 there's still a little bit of noise around. By setting a pen recheck delay we make the panel feel less touchy and twitchy. Someone with more time and patience myself might be able to tune this numbers further but these settings are now perfectly acceptable for normal use. Tested on ezLCD+101 though should only improve response on other ezLCD+/ favr-32 boards too.
