[中文](README_zh.md)
|
||||
|
||||
本文档为 tyustli 为 STM32H743-st-nucleo 开发板提供的 BSP (板级支持包) 说明。
|
||||
## MCU: STM32H743ZI @480MHz, 2MB FLASH, 1MB RAM
|
||||
|
||||
主要内容如下：
|
||||
STM32H742xI/G and STM32H743xI/G devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC core operating at up to 480 MHz. The Cortex® -M7 core features a floating point unit (FPU) which supports Arm® double-precision (IEEE 754 compliant) and single-precision data-processing instructions and data types. STM32H742xI/G and STM32H743xI/G devices support a full set of DSP instructions and a memory protection unit (MPU) to enhance application security.

### 进阶使用
|
||||
|
||||
此 BSP 默认只开启了 GPIO 和 串口3 的功能，如果需使用更多高级功能，需要利用 ENV 工具对BSP 进行配置，步骤如下：
|
||||
|
||||
1. 在 bsp 下打开 env 工具。
|
||||
|
||||
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。
