Elecrow 2.8" tft pin layout?

Other Hardware Displays

Hi,

Just purchased the Elecrow 2.8" tft display, plugged it on top of a Uno, installed the TFTV2 library, ran an example script... and all works well! Played with it for an evening and it works like sunshine. Nice device.

Now I want to have it run detached and wired, so not stacked on the UNO), and am searching for the minimum pin layout. According to Elecrow's site the pin layout (see link below) involves 11 pins, to which I added 5V and GND. Does not work.

I could of course wire all 34 pins and unplug one by one to see when it breaks... but maybe someone out there tried this already (he said, naively)...

Thanks!

Got a fast reply from support at Elecrow. Great service (thanks Bruce).

Rather than stacking the 2.8 display on the Uno, wiring is possible, with only 12 wires: pins required are:

Regular pins: 5V, GND, Reset, A0, A1, A2, A3, D5, D6
On the SPI block: MISI, MISI, SCK

Works fine! Touch and display.

Aologies - typo which may confuse future readers:

Correct text should be:

"Regular pins: 5V, GND, Reset, A0, A1, A2, A3, D5, D6
On the SPI block: MISI, MISO, SCK"
