瑞萨e2studio(19)----串口获取数据通过SPI存储于W25Q128外部flash
瑞萨e2studio.19--串口获取数据通过SPI存储于W25Q128外部flash
概述
SPI是串行外设接口(Serial Peripheral Interface)的缩写,是一种高速的,全双工,同步的通信总线,并且在芯片的管脚上只占用四根线,节约了芯片的管脚,同时为PCB的布局上节省空间,提供方便,正是出于这种简单易用的特性,越来越多的芯片集成了这种通信协议,比如 EEPROM,FLASH,实时时钟,AD转换器。
W25Q128 是一款SPI接口的Flash芯片,其存储空间为 128Mbit,相当于16M字节。W25Q128可以支持 SPI 的模式 0 和模式 3,也就是 CPOL=0/CPHA=0 和CPOL=1/CPHA=1 这两种模式。
本篇文章主要介绍如何使用e2studio对瑞萨进行spi配置,同时移植stm32上的W25Q128到瑞萨上,同时通过对该FLASH进行读写操作,验证是否正确。

硬件准备
首先需要准备一个开发板,这里我准备的是芯片型号R7FA2L1AB2DFL的开发板:
Flash就是淘宝上SPI接口的W25Q128模块。

芯片配置
本文中使用R7FA2L1AB2DFL来进行演示。
工程模板选择
SPI配置
点击Stacks->New Stack->Driver->Connectivity->SPI Driver on r_spi。
SPI属性配置
片选CS管脚设置
设置P103管脚为输出管脚,作为CS片选。
设置e2studio堆栈
e2studio的重定向printf设置
C++ 构建->设置->GNU ARM Cross C Linker->Miscellaneous去掉Other linker flags中的 “–specs=rdimon.specs”
uart配置
点击Stacks->New Stack->Driver->Connectivity -> UART Driver on r_sci_uart。
uart属性配置
配置串口,用于打印数据。
printf输出重定向到串口
打印最常用的方法是printf,所以要解决的问题是将printf的输出重定向到串口,然后通过串口将数据发送出去。
注意一定要加上头文件#include <stdio.h>
#ifdef __GNUC__ //串口重定向
#define PUTCHAR_PROTOTYPE int __io_putchar(int ch)
#else
#define PUTCHAR_PROTOTYPE int fputc(int ch, FILE *f)
#endif
PUTCHAR_PROTOTYPE
{
err = R_SCI_UART_Write(&g_uart0_ctrl, (uint8_t *)&ch, 1);
if(FSP_SUCCESS != err) __BKPT();
while(uart_send_complete_flag == false){}
uart_send_complete_flag = false;
return ch;
}
int _write(int fd,char *pBuffer,int size)
{
for(int i=0;i<size;i++)
{
__io_putchar(*pBuffer++);
}
return size;
}
STM32移植瑞萨说明
在STM32的W25Qx.h中,有个片选定义,代码如下。
#define W25Qx_Enable() HAL_GPIO_WritePin(CS_GPIO_Port, CS_Pin, GPIO_PIN_RESET)
#define W25Qx_Disable() HAL_GPIO_WritePin(CS_GPIO_Port, CS_Pin, GPIO_PIN_SET)
修改后如下所示。
#define W25Qx_Enable() R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_01_PIN_03, BSP_IO_LEVEL_LOW);
#define W25Qx_Disable() R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_01_PIN_03, BSP_IO_LEVEL_HIGH);
在STM32的W25Qx.c中,有对数据进行发送和接受,代码如下。
/* Send the read status command */
HAL_SPI_Transmit(&hspi1, cmd, 1, W25Qx_TIMEOUT_VALUE);
/* Reception of the data */
HAL_SPI_Receive(&hspi1,&status, 1, W25Qx_TIMEOUT_VALUE);
修改后如下所示。
/* Send the read status command */
g_transfer_complete = false;
err = R_SPI_Write(&g_spi0_ctrl, cmd, 1, SPI_BIT_WIDTH_8_BITS);
assert(FSP_SUCCESS == err);
/* Wait for SPI_EVENT_TRANSFER_COMPLETE callback event. */
while ( g_transfer_complete==false)
{
;
}
/* Reception of the data */
g_transfer_complete = false;
err = R_SPI_Read(&g_spi0_ctrl, &status, 1, SPI_BIT_WIDTH_8_BITS);
assert(FSP_SUCCESS == err);
/* Wait for SPI_EVENT_TRANSFER_COMPLETE callback event. */
while ( g_transfer_complete==false)
{
;
}
W25Q128说明
W25Q128将16M的容量分为256个块(Block),每个块大小为64K字节,每个块又分为16个扇区(Sector),每个扇区4K个字节。W25Q128的最小擦除单位为一个扇区,也就是每次必须擦除4K个字节。芯片ID如下所示。
0XEF13,表示芯片型号为W25Q80
0XEF14,表示芯片型号为W25Q16
0XEF15,表示芯片型号为W25Q32
0XEF16,表示芯片型号为W25Q64
0XEF17,表示芯片型号为W25Q128
演示效果
开机会打印W25Q128的ID,ID为0XEF17,实际如下所示。
并且之前保存的数据也正确读取出来了。
定义数组DataBuff,其中DataBuff[0]表示写入扇区, DataBuff[1]表示写入位置,剩下的为写入数据,同时以0xff结尾。
分别输入数据 01 02 01 02 03 04 ff与02 20 aa bb cc dd ff
