How easy is SPI with the OSHChip? I thought I'd find out by first controlling a module that has a very basic SPI-ish slave interface.

I'm using the LEDx16Module that I designed in the KiCad like a Pro course from Tech Explorations. It has dual 74HC595 shift registers that can be driven with SPI to control 16 onboard LEDs.

After bruising myself on the raw gcc toolchain - and although I got a program running - I think I want my toolchain to do more of the hard work for me!

So next I tried yotta, the software module system used by mbed OS. Building a simple program using the Official Yotta target for OSHChip and gcc on MacOSX proved quite straight-forward.

Can I build a program for the OSHChip using the gcc toolchain and Nordic Semi SDK on MacOSX?

Yes..ish!

Here are my notes and scripts for compiling and deploy a simple program, but there remain a few rough edges. There are probably easier ways to do this ... like using the Official Yotta target for OSHChip using gcc ... but I was curious to see how far I could get with just gcc and the Nordic Semi SDK.

I heard about the OSHChip on the embedded.fm podcast #146 and immediately wanted one!

An ARM Cortex-M0 32 bit micro processor (nRF51822) with 2.4 GHz Radio and other goodies all in a breadboard-compatible DIP16 package .. how could you say no?!

So far, so good. Literally 5 minutes to the first blinking LED, and hours of fun followed .. this is an awesome little package.
