This is a C++ framework for STM32F4. It is based on ST-provided stm32f4xx.h The folders are (most of the time) organized as follow:

• plat-* contain low level drivers. There is plat-unix which is are just stubs, and plat-stm with actual code. plat-inc are the matching headers. The philosphy behind them is to be a close match to actual STM32F4 registers. It hides the access to RCC clocks though, and there are some helper functions.

• drivers contain higher level drivers. They are for components external to the STM32F4 itself.

Supported drivers:

• AX-12 (one half-duplex wire, three wires, En + Tx + Rx)
• Bluetooth
• Three wires Half H-Bridge (PWM + EnA + EnB)
• HD44780-like lcd
• WS82(1112b)
• Neato XV11 Lidar

Supported STM32F4 function:

• Adc (only one shot, no DMA)
• DMA
• EXTI
• GPIO
• NVIC
• SPI
• Timer
• Uart
• UsbSerial
• Watchdog
