Hi Everybody!
I am building a HAM Transceiver-Shield for 23/13/9/6 cm wavelenghs for the Arduino Due. On the shield there ist a MAX2871 PLL_SYnthesizer-Chip, which i want to control over the second SPI, then there also is mixer i have to turn on/off, two SHF-switches to select the right bands and bandpass-filters, and a reflectometer with two A/D - conversters to meassure forwarded and reflected SHF-power. Furtermore i need a rotary-encoder with push-button and the touch-display to show and modify parameters in the menu.
So i am already using up quite a lot of analog and digital pins of the due. Thats also why i want to connect the touch-shield with dupond-cables and make it work, my shield will sit on top of the arduino, the display will be mounted to a metal-case...
I have looked into the GitHub - ImpulseAdventure/Waveshare_ILI9486: Arduino library for Waveshare ILI9486 supporting the Waveshare 3.5" & 4" TFT Touch Shields for Arduino. Includes GFX-compatible API and touchscreen driver resources and was able to compile the examples for the 4'' display and also the ws_graphictest, but only on create.arduino.cc.
On windows 10 and on my Raspberry, some examples didnt compile, i dont know why, but at least i can use create.arduino.cc...
Here is a short example (just a rudimentary test for the menu) with some graphics, which is working, using the ws_graphictest:

}
At this moment i am not sure, if the Display uses software or hardware SPI, the shield connects to the due hardware 3x2 SPI header...
In the next step i will investigate, which pins on the due i have to use, at the moment i am using more than i would like to, because i will need every pin available for my transceiver-shield...
With best regards
