Hi,

In the nRF5 SDK you can find low level drivers to use the SPIM peripheral, to send and receive any arbitrary commands and data you want.

You will need to read the documentation of the HT1632 on how these command and data should look like. If there exists a library for the HT1632, then it should be possible to include that in your project. I assume the HT1632 will require an underlying API to control chip select and send spi data, so you will likely need to modify these low level functions to provide the same functionality, by using the low level drivers from the nRF5 SDK.

Best regards,
Kenneth
