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.
