How to connect nRF52 with Waveshare LCD

[lcj]

I just receive a nRF52-DK and purchased a Waveshare 1.3inch lcd module. I am really new to this but wanted to create a simple "hello world" with it using Arduino. Is there any tutorial for something like this? I'm not sure how to connect them either. Just a little help to get started would be great. On the Waveshare I see connectors for:

• VCC
• GND
• DIN
• CLK
• CS
• DC
• RST
• BL

What do I connect them to on the nRF52-dk?

Hi,

If you want to use Arduino SW I suggest to have a look at some Arduino documentation and use Arduino forums. There is support for some nRF52 boards in Arduino, but Nordic supports nRF Connect SDK and the nRF5 SDK, so that is primarily what we can assist with here. There are some guides out there ofr using th enRF52 DK with te Arduino IDE, for instance this one.

The Display module use SPI, and the nRF52 has configurable GPIOs, so where to connect the pins depend on the firmware running on the nRF (which pins you configures for which usage). Note that if you use Arduino, the nRF DK has arudino compatible pin numbering, so you can see the pin numbers on the DK. And the documentation for the display module is also relevant.

If you want to skip Arduino and use the nRF Connect SDK instead we are happy to help here, but note that you will need to write a driver for the display yourself (unless you can find some existing to use). There are some examples of this already: Display samples.
