SPI Receive Send Dma

1 功能概述

本例程演示如何使用 SPI HAL Driver和DMA HAL Driver实现dma方式的 SPI收发功能。

2 环境准备

• 硬件设备与线材：

  • PAN107X EVB 核心板与底板各两块

  • JLink 仿真器（用于烧录例程程序）

  • USB-TypeC 线两条（用于底板供电和查看串口打印 Log）

  • 杜邦线数根或跳线帽数个（用于连接各个硬件设备）

• 硬件接线：

  • 将 EVB 核心板插到底板上

  • 使用 USB-TypeC 线，将 PC USB 插口与 EVB 底板 USB->UART 插口相连

  • 使用杜邦线将 EVB0 底板上的 P11(MOSI)、P03(CS)、P04(CLK)、P05(MISO)分别接入EVB1对应相同PAD上

  • 使用杜邦线将 JLink 仿真器的：

    • SWD_CLK 引脚与 EVB 底板的 P00 排针相连

    • SWD_DAT 引脚与 EVB 底板的 P01 排针相连

    • SWD_GND 引脚与 EVB 底板的 GND 排针相连

• PC 软件:

  • 串口调试助手（UartAssist）或终端工具（SecureCRT），波特率 921600（用于接收串口打印 Log）

3 编译和烧录

例程位置：<PAN10XX-NDK>\01_SDK\nimble\samples\peripheral\spi_master_dma_send_receive\keil_107x

NDK>\01_SDK\nimble\samples\peripheral\spi_slave_dma_receive_send\keil_107x

双击NDK>\01_SDK\nimble\samples\peripheral\spi_master_dma_send_receive\keil_107x目录下Keil Project 文件打开工程进行编译并烧录至EVB0板。

双击NDK>\01_SDK\nimble\samples\peripheral\spi_slave_dma_receive_send\keil_107x目录下Keil Project 文件打开工程进行编译并烧录至EVB1板。

4 例程演示说明

1. 先烧录spi_slave_dma_receive_send hex至EVB1，芯片会通过串口打印初始化 Log，spi slave进入接收模式，等待接收160个16bit数据：
