|
|
|
Other hardware features are not yet supported on this Zephyr port. |
|
|
|
The default configuration can be found in the defconfig file: |
|
``boards/arm/nucleo_f303re/nucleo_f303re_defconfig`` |
|
|
|
Connections and IOs |
|
=================== |
|
|
|
The Nucleo F303RE Board has 5 GPIO controllers. These controllers are |
|
responsible for pin muxing, input/output, pull-up, etc. |

|
|
Default Zephyr Peripheral Mapping: |
|
---------------------------------- |
|
|
|
The Nucleo F303RE board features an Arduino Uno V3 connector and a ST |
|
morpho connector. Board is configured as follows: |
|
|
|
- UART_2 TX/RX : PA2/PA3 (ST-Link Virtual Port Com) |
|
- USER_PB : PC13 |
|
- LD2 : PA5 |
|
|
|
System Clock |
|
------------ |
|
|
|
The Nucleo F303RE System Clock can be driven by an internal or |
|
external oscillator, as well as by the main PLL clock. By default the |
|
System Clock is driven by the PLL clock at 72 MHz. The input to the |
|
PLL is an 8 MHz external clock supplied by the processor of the |
|
on-board ST-LINK/V2-1 debugger/programmer. |
|
|
|
Serial Port |
|
----------- |
|
|
|
The Nucleo F303RE board has 2 UARTs. The Zephyr console output is assigned |
|
to UART2. Default settings are 115200 8N1. |
|
|
|
Programming and Debugging |
|
************************* |
|
|
|
The Nucleo F303RE board includes an ST-LINK/V2-1 embedded debug tool interface. |
|
This interface is supported by the openocd version included in Zephyr SDK. |
