Detailed Description
Support for the STM32F3Discovery board.
Overview
The STM32F3Discovery is cheap evaluation board designed by ST for pushing the STM32F3 microcontroller to a broad audience. It features an STM32F303VC microcontroller with 48Kb of RAM and 256Kb flash memory running with up to 72MHz. Additionally it provides USB host capabilities, 8 LEDs and sensors for a 9-degree of freedom initial measurement unit (3-axis accelerometer, 3-axis gyro and 3-axis magnetometer).

Flashing the Board
A detailed description about the flashing process can be found on the guides page. The board name for the STM32F3discovery is stm32f3discovery.
Using UART
- connect your usb tty to: RX=PA10 TX=PA9 and GND=GND
- PA10 is connected with TX on the UART converter
- PA9 is connected with RX on the UART converter
- done
