2x16 LCD and Rotary Encoder

[jengil]

Hello,

I've been looking around to find the best way to interface the nRF52 DK with both an LCD screen for printing settings to a panel display, and a rotary encoder, used to scroll through and enter into various menus.

The rotary encoder would be any simple 5pin quadrature or 2bit grey code input that I could find, and the LCD screen would be something like this: www.newhavendisplay.com/nhd0216k1zflybw-p-284.html

I have worked with components like this extensively on Arduino and simpler interfaces but don't understand the software/coding necessary to get these working for the nRF52. I am confident I can hook them up properly however, which is a good first start.

I really have no idea where to begin and would like to find the simplest and most straightforward method of learning to interface these components.

Any help would be greatly appreciated.

Thanks and Regards

Personally I wouldn't recommend starting with the arduino drivers which in most cases (unless they were custom written for an nrf51 chip) are bitbangers.

The rotary coder shouldn't be too hard, the nrf51 has a QDEC peripheral built in which scans and reports movement on any compatible input device. There's a driver in the SDK for it, nrf_drv_qdec, which follows the same basic method of use of any of the other nordic drivers. Don't think there's an example for that one, but if you look at some of their general example code, you should get the idea.

LCD, you'd be better off with one with a I2C or SPI interface, if I read that one correctly it's got a 7-bit wide one which is possible to do, but again the nrf51 series has I2C and SPI peripherals, and drivers, and examples, so reading and writing those are easy.

Rotary encode and LCD .. not a reflow oven is it? :)
