nRF51822 Support

[netthier]

Hey, is any support for the nRF51822, used by the Calliope Mini, planned?
If not, how hard would it be to implement?

We don't currently have a PAC for that chip, so you'd have to add one to https://github.com/nrf-rs/nrf-pacs. Then, adding HAL support should be relatively straightforward (you can check #148 for an example PR adding support for a new chip).

Do you know where I could find the SVD file for that chip? I tried downloading the MDK, and while it does contain SVD's for a lot of chips, there are only the following, relatively short, files for the 51822:

• nrf51822_peripherals.h
• nrf51822_xxaa.ld
• nrf51822_xxab.ld
• nrf51822_xxac.ld

Furthermore, the header file contains the line
/* This file is deprecated */
How would I generate a PAC crate for this chip?

Oh, nRF51822, that's already supported by the nrf51-pac and nrf51-hal. I thought it said nRF52822, which does not seem to exist.

Ah, that's awesome. Thanks!
