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.

- Fixed bug on clearing queue during sleep/wake-up.
Writing sleep command while touch IC is pushing data into queue,
could have caused non-empty queue after wake up sequence.

Firmware 0x31 is made up based on 0x50 and have reduced number of sampling
performed, to reduce chance of circuit getting in unstable condition.
Updates for 0x50 are described below.
- Analog parameters for sample circuit has been optimized to new
hardware.
- Embodied new feature that firmware automatically recognizes noisy
environment and changes it's operating mode.
- Precision on bottom of touch screen has been improved.
