Hi all,
finally I found a successful and easy way, at least to me, to use any
resistive touchscreen with the BB on any OS . My experiences ( I hope
will be useful for some of you):
EGALAX TOUCH DRIVER: Usb touchscreen controller very common on small
monitors (overcoat for cars). Not HID compliant. Drivers are not
compatible with ARM architecture. I couldn't make it work in any OS
(Ubuntu, Angstrom and Android).
TSHARC OCTOPUS. USB touchscreen controller for 4,5 and 8 wires. Ideal
if you buy the TFT and the touchscreen separately. HID compliant.
Drivers work perfectly with ARM. CONS: board is quite expensive (80$)
and hard to find.Don't work in Android. On other hand you can build
your own board, the schematic is easy and you just need the IC (10$)
and few additional components but.. the minimum order for the IC
rounds 40 parts (distributed by Microchip).
ADS7846: Probably the most robust solution. I'm newbie on ARM and
almost on Linux. By now I think I'm not able to rebuild the kernel and
make it work. In the future I would like to use this solution.
CUSTOM CONTROLLER. The way I've taken finally. Use any 8bit
microcontroller with USB DEVICE and AD converter (5$-8$). Use the AD
converter to take the touches later send the data to the BB emulating
a USB mouse (the protocol is easy). Cheap, easy and driver is not
needed: works with UBUNTU, ANGSTROM and ANDROID. CONS: 1. You need to
have some experience in uC&USB. 2.The mouse cursor is not elegant, at
all: I'm working in hide it.
Regards.
