Re: Teensy 3.0 to STM32f 103

Well, Teensy implement some Class/API which are not implemented in Roger's core. Ex: IntervalTimer Class https://github.com/PaulStoffregen/cores/blob/fc79132670ac83ce7cae8e2bac64be109fbfe35e/teensy3/IntervalTimer.h analogReadResolution API https://github.com/PaulStoffregen/cores/blob/556b4b4c5d4c6cf...

Re: Designating variables to backup SRAM (LibMaple)

OK ;)
Ok, don't know if libMaple have API for this.
Anyway, it should be achievable if not available using some example available on the net and using datasheet.

Normally the default windows VCP driver is enough.

Re: Introducing the new Arduino core for STM32

Hi Robca, DFU should be available soon. Probably in the next release. BennehBoy made a PR to add the support: https://github.com/stm32duino/Arduino_Core_STM32/pull/415 About CMSIS DSP, I never use it, I guess you have to include the proper header, probably the path should be added in the platform.tx...

Re: Square wave output from timer pin

Don't know how you handle install but Arduino_Core_STM32 require arm gcc v6.
So install it from the board manager then it will install all required dependencies (tools, arm gcc and CMSIS).
