2.2" Color LCD Booster Pack with Touch

Recommended Posts

LCDs are here, will ship them in few days (SA, yours is shipping on Monday so you don't have to drool anymore :) )

 

BTW, the touch chip will not be included, you have to get one and solder it by yourself.

I can get them, but that would further delay this board.

Is there a pre order for there goodies? :D

 

Looks awesome as always RobG! Will keep an eye on the 43oh store. Hopefully I can manage to get one of these before they sell out. :D Any info regarding the touch chip and what all is required to get it to work? Either way, a 2.2" SPI based screen for that price is darn nice regardless.

Not sure if I should laugh or cry, but it seems that this board is cursed.

After unsuccessful tests with my first board, assembled and tested the second one, still no touch.

Took a closer look at the LCD, bam! datasheet is wrong again, Y-, X+, Y+, X- are actually Y-, Y+, X-, X+.

No wonder the touch chip didn't work.

Looks like it's going to be another 3 weeks :(

Still needs some work, but it's a good start.

With just one small adjustment to the board, I can use MSP430's ADC to read the touch panel.
The speed should be comparable with touch controller chip (TSC2046's max clock speed is 2MHz.)

Looks like the controller chip might not be necessary. Software touch works pretty good, just needs some filtering.

The only thing, software touch uses P1.1-P1.4 and P2.1, so forget about UART. Hardware touch uses P1.4, P2.0, and P2.2.
