Recommended Touchscreen for nRF52810

Question

Hello, 
 I am designing a wearable using the nRF52810 chip and would like to ask if there are any recommended touchscreens to be used? My main concerns are 
 
 SPI bus (at 8MHz) is fast enough to drive a suitable refresh rate 
 Size, looking for something around a 1 inch diagonal/diameter 
 Touch interface that is compatible with the chip 
 
 Thank you!

Like I explained above, the 8 MHz SPI interface is capable of transferring more than double the data rate required for 240x240 pixels @ 60 Hz refresh rate. If the interface will be a bottleneck will depend on how data are written to the display, and how often you need to update the data being transmitted. 
 If you can reduce the refresh rate is not something I can answer. You will have to check the datasheet of your device about that. The nRF can control anything over SPI so if you display support lower refresh rates, there should be no problems.
