开发板介绍

板子非常漂亮哦。

资源也很丰富：

1个复位按键

2个用户按键

2个触摸按键

3个LED

2个PMOD接口

板载USB转TTL模块，可用于串口通信和烧录

板载SWD接口，方便用户调试与下载

支持 TrustZone 的 100MHz Arm Cortex-M33

安全芯片的功能

512kB 闪存、64kB SRAM（支持奇偶校验）以及 64kB ECC SRAM

8KB 数据闪存，提供与 EEPROM 类似的数据存储功能

1kB 休眠用 SRAM

100 引脚封装

电容式触摸传感单元 (CTSU)

全速 USB 2.0，支持主机模式和设备模式

CAN 2.0B

四线 SPI

SCI（UART、简单 SPI、简单 I2C）

独立SPI/I2C 多主接口

SDHI 和 MMC

开发环境

采用e2stuio进行编码开发。

FSP非常好用，管脚配置方便。

代码实现

这里学习一下，LED的驱动。做一个流水灯效果

参考代码如下：

#include "hal_data.h"

FSP_CPP_HEADER
void R_BSP_WarmStart(bsp_warm_start_event_t event);
