## 简介
|
[中文](README_zh.md)
|
||||||
|
|
||||||
本文档为ST官方 NUCLEO-L433RC-P 开发板的 BSP (板级支持包) 说明。
|
## MCU: STM32L433RC @80MHz, 256KB FLASH, 64KB RAM
|
||||||
|
|
||||||
主要内容如下：
|
The STM32L433xx devices are the ultra-low-power microcontrollers based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 80 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all Arm® single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.
|
||||||
|
|
||||||
- 开发板资源介绍
|
The STM32L433xx devices embed high-speed memories (Flash memory up to 256 Kbyte, 64 Kbyte of SRAM), a Quad SPI flash memories interface (available on all packages) and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.
|
||||||
- BSP 快速上手
|
The STM32L433xx devices embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, proprietary code readout protection and Firewall.
|
||||||
- 进阶使用方法
|
The devices offer a fast 12-bit ADC (5 Msps), two comparators, one operational amplifier, two DAC channels, an internal voltage reference buffer, a low-power RTC, one general-purpose 32-bit timer, one 16-bit PWM timer dedicated to motor control, four general-purpose 16-bit timers, and two 16-bit low-power timers.
|
||||||
|
In addition, up to 21 capacitive sensing channels are available. The devices also embed an integrated LCD driver 8x40 or 4x44, with internal step-up converter.
|
||||||
|
They also feature standard and advanced communication interfaces.
|
||||||
|
The STM32L433xx operates in the -40 to +85 °C (+105 °C junction), -40 to +105 °C (+125 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V VDD power supply when using internal LDO regulator and a 1.05 to 1.32V VDD12 power supply when using external SMPS supply. A comprehensive set of power-saving modes allows the design of low-power applications.
|
||||||
|
Some independent power supplies are supported: analog independent supply input for ADC, DAC, OPAMP and comparators, and 3.3 V dedicated supply input for USB. A VBAT input allows to backup the RTC and backup registers. Dedicated VDD12 power supplies can be used to bypass the internal LDO regulator when connected to an external SMPS.
|
||||||
|
The STM32L433xx family offers eight packages from 48 to 100-pin packages.
|
||||||
|
|
||||||
通过阅读快速上手章节开发者可以快速地上手该 BSP，将 RT-Thread 运行在开发板上。在进阶使用指南章节，将会介绍更多高级功能，帮助开发者利用 RT-Thread 驱动更多板载资源。

|
|
||||||
|
|
||||||
2. 输入`menuconfig`命令配置工程，配置好之后保存退出。
|
|
||||||
|
|
||||||
3. 输入`pkgs --update`命令更新软件包。
|
|
||||||
|
|
||||||
4. 输入`scons --target=mdk4/mdk5/iar` 命令重新生成工程。

|
||||||
## 注意事项
|
|
||||||
|
|
||||||
- 开机时如果不能打印 RT-Thread 版本信息，请将BSP中串口 GPIO 速率调低
|
|
||||||
- 开机时如果不能打印 RT-Thread 版本信息，请重新选择 PC 端串口调试软件的串口号
