@brief Support for the STM32F3Discovery board
|
|
|
|
## Overview
|
|
|
|
The STM32F3-discovery is cheap evaluation board designed by ST for pushing
|
|
the STM32F3 microcontoller to a broad audience. It features an STM32F303VC
|
|
microcontroller with 48Kb of RAM and 256Kb flash memory running with up to
|
|
72MHz. Addionially 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).
|
|
|
|
The board does however not provide any radio capabilities, radio devices have
|
|
to be connected externally via I2C, SPI, UART or similar.
|
|
|
|
See [this page](https://github.com/RIOT-OS/RIOT/wiki/Getting-started-with-STM32F%5B0%7C3%7C4%5Ddiscovery-boards)
|
|
for a quick getting started guide.

## Flashing the device
|
|
|
|
|
|
The STM32F3discovery board includes an on-board ST-LINK V2 programmer. The
|
|
easiest way to program the board is to use OpenOCD. Once you have installed
|
|
OpenOCD (look [here](https://github.com/RIOT-OS/RIOT/wiki/OpenOCD) for
|
|
installation instructions), you can flash the board simply by typing
|
|
|
|
```
|
|
make flash
|
|
```
|
|
and debug via GDB by simply typing
|
|
```
|
|
make debug
|
|
```
|
|
|
|
|
|
## Supported Toolchains
|
|
|
|
For using the STM32F3discovery board we strongly recommend the usage of the
|
|
[GNU Tools for ARM Embedded Processors](https://launchpad.net/gcc-arm-embedded)
|
|
toolchain.
|
|
|
|
|
|
## Using UART
|
|
|
|
1. 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
|
|
2. done
