NUCLEO-WB55RG README
======================
This README file discusses the port of NuttX to the STMicroelectronics
NUCLEO-WB55RG board. That board features the multi-protocol wireless and
ultra-low-power STM32WB55RGV6 MCU with 1MiB of Flash and 256KiB of SRAM.
A dedicated M0+ coprocessor is responsible for performing the real-time
low layer operations via one of the available wireless stacks distributed
as binaries in STM32CubeWB package.

Status
======
April 2022: The nucleo-wb55rg board minimal setup compiles successfully.
June 2022: All STM32WB chip family is defined, many of peripherals are
supported - GPIO, EXTI, DMA, timers, flash, PWR, RTC, USART/LPUART, SPI,
IPCC. SRAM2 heap allocation works. Builtin apps work and ostest passed.
LEDs
====
The board has 3 user leds:
LED1 (Blue) PB5
LED2 (Green) PB0
LED3 (Red) PB1
These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
defined. In that case, the usage by the board port is defined in
include/board.h and src/stm32_autoleds.c.
Buttons
=======
The board has 3 user buttons:
SW1 PC4 (needs SB47 close)
SW2 PD0
SW3 PD1
Serial Consoles
===============
The MCU's USART1 is connected to the on-board ST-LINK/V2-1 and exposed as
a Virtual COM Port over the same Micro-USB Type B connection used for
programming/debugging.
Configurations
==============
nsh:
Configures the NuttShell (nsh) located at examples/nsh. This
configuration is focused on low level, command-line driver testing.
