[tocm] 看的舒服点的链接,~~论坛这个格式调起来好抽象~~ https://wwwangguan.github.io/2024/08/09/qian-ru-shi-ruan-jian/rt-thread/xmc7200evk-spi/ # BSP修改与SPI配置 首先在board/Kconfig里面加入SPI配置 ```bash menuconfig BSP_USING_SPI bool "Enable SPI BUS" select RT_USING_SPI default n if BSP_USING_SPI menuconfig BSP_USING_SPI0 bool "Enable SPI0 BUS" default n menuconfig BSP_USING_SPI3 bool "Enable SPI3 BUS" default n if BSP_USING_SPI3 config BSP_USING_SPI3_SAMPLE bool "Enable SPI3 BUS Sample" default n endif menuconfig BSP_USING_SPI6 bool "Enable SPI6 BUS" default n endif ``` ![screenshot_202408141359940.png](https://oss-club.rt-thread.org/uploads/20240909/815801e062097060599b146569d5166e.png) 然后在menuconfig开启即可,但是需要修改一下drv_spi.c的引脚 ![screenshot_202408130926156.png](https://oss-club.rt-thread.org/uploads/20240909/a9df0f9d7949247586d65aef41a4f724.png.webp) 引脚修改成EVK上对应的引脚即可,我这里用的是Arduino接口上的SPI,也是官方例程使用的SPI。 配置与应用代码如下所示 ```c /* * Copyright (c) 2006-2023, RT-Thread Development Team * * SPDX-License-Identifier: Apache-2.0 * * Change Logs: * Date Author Notes * 2024-05-22 LZero first version */ #include

//software reset // ADI_Write_Reg(imu, GLOB_CMD_REG + 1, 0x80); uint16_t send[2] = {((GLOB_CMD_REG | 0x80) << 8) | 0x80, (((GLOB_CMD_REG + 1) | 0x80) << 8) | 0x80}; uint16_t receive[2] = {0}; rt_spi_send_then_recv(imu->spi_device, send, 2, receive, 2); imu->K_G = 40; imu->KG_Reciprocal = (float) (1 / imu->K_G); rt_thread_mdelay(2000); // wait for reboot } ``` 这么写之后的波形是这样的,孩子怪可怜的 ![screenshot_202408121533643.png](https://oss-club.rt-thread.org/uploads/20240909/ba9a9f3c1f88a72101f97011ec3d997f.png) 对比HAL的波形 ```c void ADIS16467_Init(ADIS16467_T *imu) { uint16_t send[2] = {((GLOB_CMD_REG | 0x80) << 8) | 0x80, (((GLOB_CMD_REG + 1) | 0x80) << 8) | 0x80};

//software reset ADI_Write_Reg(imu, GLOB_CMD_REG + 1, 0x80); imu->K_G = 40; imu->KG_Reciprocal = (float) (1 / imu->K_G); HAL_Delay(4000); // wait for reboot } int8_t ADI_Write_Reg(ADIS16467_T *imu, uint8_t addr, uint8_t value) { addr |= 0x80;

// rt_spi_send_then_recv(imu->spi_device, &trans, 1, &result, 1); rt_spi_transfer(imu->spi_device, &trans, &result, 1); return result; } ~~~ 还是慢,两次transfer时间相差15ms ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/202408130858604.png) HAL对比,函数使用HAL_SPI_TransmitReceive,两次传输时间相差39$\mu s$,怪离谱的。 ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/202408130904775.png) 尝试提升线程优先级? ~~~C int main(void) { spitest = rt_thread_create("spitest", SPIRTTEST, RT_NULL, 4096, 20, 20); rt_thread_startup(spitest); /* set LED2 pin mode to output */ rt_pin_mode(LED2_PIN, PIN_MODE_OUTPUT); while (1) { rt_pin_write(LED2_PIN, PIN_HIGH); rt_thread_mdelay(500); rt_pin_write(LED2_PIN, PIN_LOW); rt_thread_mdelay(500); }} ~~~ priority改成10?试了,没用,这真的慢。 ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/202408130914709.png) # EVK板载QSPI Flash 换用QSPI,更换逻分之后再尝试 ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/Pasted%20image%2020240810170117.png) 原理图如图所示,型号为S25FL512SAGMFMR10,英飞凌自己家的,参数挺好 ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/Pasted%20image%2020240810170337.png) 引脚映射在下图 ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/Pasted%20image%2020240810170201.png) 使用SPI0/SPI3模式 ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/Pasted%20image%2020240810170802.png) 支持SFDP,这下好办了,可以直接使用RTT的SFUD ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/Pasted%20image%2020240810171424.png) ## Kconfig文件修改 添加以下内容 ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/Pasted%20image%2020240810171833.png) scons重新生成cmakelist之后提示 ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/Pasted%20image%2020240810172000.png) 尝试 pkgs -Update,发现无效 ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/Pasted%20image%2020240810172154.png) 尝试在menucongfig中启用对应软件包,该软件包对此报错无效,且在HAL中无法找到此文件 ![](https://raw.githubusercontent.com/WwWangGuan/pics/main/Pasted%20image%2020240810180618.png) 问题:有对应的头文件,但是其实现却在drv_flash.c中,疑似官方错误,英飞凌的官方包也没有这个东西,在cmakelist中删除文件后能通过编译,但是AC6编译未能通过。
