PicoMite V6.00.02b6 now supports capacitive touch using the FT6336 chip.
In theory this chip supports touch reporting of up to 2 points at once AND simple gesture control.
There are lots of boards with the chip available from the usual places
I bought a couple as they look to have great potential with the PicoMite.
The display itself is an IPS 320x240 controlled by the ILI9341 chip and this works nicely (It does need the INVERT option on the setup). In theory there is a SDcard socket but on my boards various of the required pins are not connected so that is useless. The FT6336 works and the firmware does support dual touch however touch seems very laggy. Gesture controls do not work and google reveals the manufacturer of the chip has produced versions both with and without this facility.
Overall, the module is disappointing. I suspect the reason they are available cheap is that a large batch were produced with a wiring error on the PCB (no SDcard connections) and sub standard FT6336 chips.
If you just need a bright display with touch they are OK but no real advantage over the standard ILI9341 with resistive touch.
