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¶
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：
