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 STM32F407 MCU used with STM32Generic Arduino core by danieleff.

Arduino core is located at:

https://github.com/danieleff/STM32GENERIC

Unzip it into [Arduino]/hardware folder

This HAL is in development.

This HAL is a modified version of Chris Barr's Picoprint STM32F4 HAL.
