[中文](README_zh.md)
|
||||
|
||||
本文档为 RT-Thread 开发团队为 NUCLEO-F412ZG 开发板提供的 BSP (板级支持包) 说明。
|
||||
## MCU: STM32F412ZG @100MHz, 1024KB FLASH, 256KB RAM
|
||||
|
||||
主要内容如下:
|
||||
STM32F412xE/G devices are based on the high-performance Arm® Cortex® -M4 32-bit RISC core operating at a frequency of up to 100 MHz. Their 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.

|
||||
- BSP 快速上手
|
||||
- 进阶使用方法
|
||||
STM32F412xE/G devices belong to the STM32 Dynamic Efficiency™ product line (with products combining power efficiency, performance and integration) while adding a new innovative feature called Batch Acquisition Mode (BAM) allowing even more power consumption saving during data batching.
|
||||
STM32F412xE/G devices incorporate high-speed embedded memories (up to 1 Mbyte of Flash memory, 256 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
|
||||
All devices offer one 12-bit ADC, a low-power RTC, twelve general-purpose 16-bit timers, two PWM timers for motor control and two general-purpose 32-bit timers.
|
||||
They also feature standard and advanced communication interfaces:
|
||||
In addition, STM32F412xE/G devices embed advanced peripherals:
|
||||
STM32F412xE/G devices are offered in 7 packages ranging from 48 to 144 pins. The set of available peripherals depends on the selected package.
|
||||
The STM32F412xE/G operates in the -40 to +125 °C temperature range from a 1.7 (PDR OFF) to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.
|
||||
These features make the STM32F412xE/G microcontrollers suitable for a wide range of applications.
|
||||
|
||||
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。
