I've got my development environment up & running now.  

I'm using the gcc-arm-none-eabi-7-2018-q2-update toolchain from Arm's website on my Mac.  Kind of happy about the Mac part just because it's nice to not to have to run say, Linux in a VM for this.

Next step will probably be to write some preliminary code using the Circle library.

Rebecca,

think you might find this, and the links you find there, interesting: https://github.com/phorton1/circle-prh-apps-Looper/blob/master/docs/software.md      

you can actually hear it at https://m.youtube.com/watch?v=tGht04neoQ8 

i would be more than happy if you could build guitar effects in that framework.

I am either gonna work on a synth, or try to do "time stretching" in the looper, and/or record more, so there's plenty of time, but effects are on my list somewhere down the road.

Hope you are well.

Peace,

- Patrick
