Touch Screen options

Post by gyrogale »

Good afternoon,

I am using an Arduino Mega 2560, coupled with a 3-axis accel and gyro to measure the angle of roll, speed of the roll and sending the information to a servo motor to correct the roll and keep my platform steady at all times. I am currently using pots to increase the gains to increase sensitivity depending on motions I am receiving. As of right now the information is displayed on the standard LCD screen.

I want to shift over from using knobs and pots to using a 4" to 5" touch screen. If you could please direct me in the proper direction it would be much appreciated.

Thank you

Zeyad

We do have a 5" LCD with touchscreen: http://www.adafruit.com/products/1596
You will need a driver board to go with that: http://www.adafruit.com/products/1590
We have a library for this product here: https://github.com/adafruit/Adafruit_RA8875

Thank you for the information, I did take a look at it...How would I upload graphics? Can I transfer JPEG images or how does that work? For example the arrows that I will be using to increase and decrease the values, and also to dim the screen as well?

The library supports all of the GFX library functions in addition to the touchscreen. The GFX library is documented here: http://learn.adafruit.com/adafruit-gfx-graphics-library
