|
|
The default configuration can be found in the defconfig file:
|
|
``boards/arm/nucleo_f302r8/nucleo_f302r8_defconfig``
|
|
|
|
Connections and IOs
|
|
===================
|
|
|
|
The Nucleo F302R8 Board has 5 GPIO controllers. These controllers are
|
|
responsible for pin muxing, input/output, pull-up, etc.

Default Zephyr Peripheral Mapping:
|
|
----------------------------------
|
|
|
|
The Nucleo F302R8 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)
|
|
- UART_3 TX/RX : PC10/PC11
|
|
- I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
|
|
- SPI1 CS/SCK/MISO/MOSI : PB6/PB13/PB14/P15 (Arduino SPI)
|
|
- PWM_2_CH2 : PA0
|
|
- USER_PB : PC13
|
|

|
|
|
|
System Clock
|
|
------------
|
|
|
|
The Nucleo F302R8 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 F302R8 board has 3 UARTs. The Zephyr console output is assigned
|
|
to UART2. Default settings are 115200 8N1.
|
|
|
|
|
|
Programming and Debugging
|
|
