Mouse/keyboard/touchscreen alternatives?

This is about as far as I have gotten. The screen is a 7" 800cd/m2 touch. There is no touch controller yet and the Adafruit TFTFriend only provides 125mA, instead of the 180 needed for max brightness.

Hi mkeveney,
I think i've made what you dream of .. I've found an old NAVIONICS GEONAV 6 CABIN which was unusable ... and too old. I've taken out the screen and the board and put a 5" HDMI screen, a PI3, a serial NEO 6 GPS, a bluetooth dongle, a RTLSDR dongle all in the box. In order to keep the keyboard usable, i've developp a board with usb interface recognised as a keyboard. You can program the shortcuts as you want. Everything works perfectly except the RTLSDR dongle but i'll open a new thread. And the good thing is that the box is waterproof and, if you need to tune it, simply turn on the BT keyboard with touch pad (few $ on ebay). If you want more details, just ask me.

That is cool! Do the buttons work?

Yes, each button correspond a keyboard shortcut.
Page = F2 Zoom plus = + Zoom minnus = - Enter = enter Clear = Escape Goto = Alt The light button drives a transistor with 4 leds The good thing is tha i can add multi touch shortcut if needed. I only have to modify the source code, build the hex file and load it into the ATMEGA8A of my board. |
