| |
| 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. |
