etagle 0566badcef Add memory barrier, optimal interrupt on-off 
Disabling an ISR on ARM has 3 instructions of latency. A Memory barrier is REQUIRED to ensure proper and predictable disabling. Memory barriers are expensive, so avoid disabling if already disabled (See https://mcuoneclipse.com/2015/10/16/nvic-disabling-interrupts-on-arm-cortex-m-and-the-need-for-a-memory-barrier-instruction/)

README.md

This HAL is for the STM32F765 board "The Borg" used with STM32Generic Arduino core by danieleff.

Original core is located at:

https://github.com/danieleff/STM32GENERIC

but i have not committed the changes needed for the Borg there yet, so please use:

https://github.com/Spawn32/STM32GENERIC

Unzip it into [Arduino]/hardware folder

Download the latest GNU ARM Embedded Toolchain:

https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads

(The one in Arduino dosen't support STM32F7).

Change compiler.path in platform.txt to point to that you downloaded.

This HAL is in development.

Currently only tested on "The Borg".

You will also need the latest Arduino 1.9.0-beta or newer.

This HAL is a modified version of Chris Barr's Picoprint STM32F4 HAL, so shouldn't be to hard to get it to work on a F4.
