Overview

The STM32F4 platform implements the Platform Library private API for a subset of STM32F4 processors. The STM32F4 platform implementation uses the following resources:

• Timer 2, to provide the CPU tick as part of platform_cpu_tick.
• Port interrupt handlers for each port, to enable hooks on pins with platform_hook_pin_edge.

SPI communication is DMA-driven.
