Hi,

We have prepared a simple GFX library - maybe it will be usefull for you. infocenter.nordicsemi.com/.../lib_gfx.html

It is available in SDK13.x and SDK14.x but it shall be not a big deal to import it to SDK 12.3 (last one supporting nRF51)

Got it.

Thanks for your prompt reply.

I guess that has nothing to do with nRF5x itself. It doesn't have any graphic coprocessor nor any sopecific interface so just GPIO/I2C/UART/SPI displays are possible. Then if the library can run on ARM Cortex-M then it should work on nRF5x chips as well. What can be a problem:

If it uses some extended instructions (ARM Cortex-M0 doesn't support full Thumb 1/2 sets and also no DSP or floating point instructions). But if you have it in source you might substitute them during build by SW implementations (which will be much slower).
You can easily hit performance issues. Firstly because of ARM Cortex-M0 design limits and secondly when you will be using BLE radio (which will interrupt any other computation unless it is DMA assisted transfer on pre-buffered interface like SPI...)

However you can see some interesting demos with nRF52 (like this and this).
