Any programming guide for nRF51822?

[peter]

Might I know any programming guide for nRF51822. The online documentation seems focus on the API instead. I would like to know more detail on SFR (special function register), any documentation / reference?

Hi Peter,

If you're thinking of the SWD interface (SWDCLK/SWDIO), most of the documentation is available from ARM. What we have is the chapter in the reference manual which explains how to enter debug/programming mode.

You should have a look at the document "ADI v5 Architecture Interface Design", which is available from ARMs website (requires login): silver.arm.com/.../AR551

Cheers, Håkon

Hi Hakon,

Before login the page you recommended, might I know if the document include GPIOTE_INTENSET detail such as the function of each bit? It just one of examples. It is a bit difficult for me to know the detail of the chip base on the header file (nf51_bitfield.h) only... I had experienced fail on change the pin from input to output just because the i hadn't disabled the gpiote... that is something hadn't shown on header file. I spent few hour on this... if I had a programming guide like atmel doing (e.g. www.atmel.com/.../doc8025.pdf) , I believe I can solve it much faster...
