Updated firmware 0x53 correspond to rev.32 and 0x33 correspond to rev.31
are attached hereto.
Updates are described below.
- Added an verification code at the end of binary, so the firmware can detect
flash failure.
It will return value 0xFF when host tries to access version information in
case of flash failure.
- Adjusted sampling parameters to fix ghost touch issues.
Ghost touches can appear due to oscillator deviation of touch IC or thermal
effect.
Algorithm for to detect and avoid noisy frequency band is added.
