前言
一、具体流程
- 第1步进入目录
- 第2步进入gpio目录并创建如下文件/目录
- 第3步编写Makefile文件（代码如下）
- 第4步编写proj_config.mk文件（代码如下）
- 第5步编写README.md文件（代码如下，该文件不参与执行）
- 第6步进入gpio目录并创建如下文件
- 第7步根据原理图编写main.c文件（代码如下）
- 第8步编写bouffalo.mk文件（代码如下）
二、编译并烧录
- 第1步进入~/Ai-Thinker-WB2/applications/get-started/gpio目录
- 第2步执行make -j8
- 第3步执行make flash p=/dev/ttyUSB0 b=115200（此时模组需要连接到虚拟机）
三执行结果图
总结

前言

本期博客介绍使用库编写gpio驱动RGB灯。
如果想要使用下面流程，请先查看Linux Ubuntu下烧录固件的过程，点击此链接进行查看

一、具体流程

第1步进入目录

cd ~/Ai-Thinker-WB2/applications/get-started
创建目录gpio

第2步进入gpio目录并创建如下文件/目录

第3步编写Makefile文件（代码如下）

## This is a project Makefile. It is assumed the directory this Makefile resides in is a# project subdirectory.#PROJECT_NAME :=gpio PROJECT_PATH :=$(abspath.)PROJECT_BOARD :=evbexportPROJECT_PATH PROJECT_BOARD#CONFIG_TOOLPREFIX :=-include./proj_config.mk ifeq($(origin BL60X_SDK_PATH), undefined)BL60X_SDK_PATH_GUESS ?=$(shellpwd)BL60X_SDK_PATH ?=$(BL60X_SDK_PATH_GUESS)/../../..$(info ****** Please SET BL60X_SDK_PATH ******)$(info ****** Trying SDKPATH[$(BL60X_SDK_PATH)])endif COMPONENTS_BLSYS :=bltime blfdt blmtd bloop loopadc looprt loopset COMPONENTS_VFS :=romfs INCLUDE_COMPONENTS+=freertos_riscv_ram bl602 bl602_std newlibc hosal mbedtls_lts lwip vfs yloop utils cli blog blog_testc coredump INCLUDE_COMPONENTS+=$(COMPONENTS_NETWORK)INCLUDE_COMPONENTS+=$(COMPONENTS_BLSYS)INCLUDE_COMPONENTS+=$(COMPONENTS_VFS)INCLUDE_COMPONENTS+=$(PROJECT_NAME)include$(BL60X_SDK_PATH)/make_scripts_riscv/project.mk

第4步编写proj_config.mk文件（代码如下）

##compiler flag config domain##CONFIG_TOOLPREFIX :=#CONFIG_OPTIMIZATION_LEVEL_RELEASE := 1#CONFIG_M4_SOFTFP := 1##board config domain#CONFIG_BOARD_FLASH_SIZE :=2#firmware config domain##set CONFIG_ENABLE_ACP to 1 to enable ACP, set to 0 or comment this line to disable#CONFIG_ENABLE_ACP:=1CONFIG_BL_IOT_FW_AP:=1CONFIG_BL_IOT_FW_AMPDU:=0CONFIG_BL_IOT_FW_AMSDU:=0CONFIG_BL_IOT_FW_P2P:=0CONFIG_ENABLE_PSM_RAM:=1#CONFIG_ENABLE_CAMERA:=1#CONFIG_ENABLE_BLSYNC:=1#CONFIG_ENABLE_VFS_SPI:=1CONFIG_ENABLE_VFS_ROMFS:=1CONFIG_EASYFLASH_ENABLE:=0CONFIG_SYS_APP_TASK_STACK_SIZE:=4096CONFIG_SYS_APP_TASK_PRIORITY:=15CONFIG_FREERTOS_TICKLESS_MODE:=0CONFIG_SYS_VFS_ENABLE:=1CONFIG_SYS_VFS_UART_ENABLE:=1CONFIG_SYS_AOS_CLI_ENABLE:=0CONFIG_SYS_AOS_LOOP_ENABLE:=1CONFIG_SYS_BLOG_ENABLE:=1CONFIG_SYS_DMA_ENABLE:=0CONFIG_SYS_USER_VFS_ROMFS_ENABLE:=0CONFIG_BL602_USE_ROM_DRIVER:=1CONFIG_BT_CENTRAL:=1CONFIG_BT_OBSERVER:=1CONFIG_BT_PERIPHERAL:=1CONFIG_BT_STACK_CLI:=1CONFIG_BT_WIFIPROV_SERVER:=1CONFIG_WIFI:=0CONF_ENABLE_COREDUMP:=1LOG_ENABLED_COMPONENTS:=blog_testc hosal loopset looprt bloop gpio

第5步编写README.md文件（代码如下，该文件不参与执行）

第6步进入gpio目录并创建如下文件

第7步根据原理图编写main.c文件（代码如下）

#include<stdio.h>#include<string.h>#include<FreeRTOS.h>#include<task.h>#include<bl_gpio.h>#defineGPIO_B_PIN3#defineGPIO_R_PIN14#defineGPIO_G_PIN17voidblink_test(void*param){bl_gpio_enable_output(GPIO_B_PIN,0,0);bl_gpio_enable_output(GPIO_R_PIN,0,0);bl_gpio_enable_output(GPIO_G_PIN,0,0);while(1){bl_gpio_output_set(GPIO_B_PIN,1);vTaskDelay(1000);bl_gpio_output_set(GPIO_B_PIN,0);bl_gpio_output_set(GPIO_R_PIN,1);vTaskDelay(1000);bl_gpio_output_set(GPIO_R_PIN,0);bl_gpio_output_set(GPIO_G_PIN,1);vTaskDelay(1000);bl_gpio_output_set(GPIO_G_PIN,0);}}voidmain(void){xTaskCreate(blink_test,"blink",1024,NULL,15,NULL);}

第8步编写bouffalo.mk文件（代码如下）

## "main" pseudo-component makefile.## (Uses default behaviour of compiling all source files in directory, adding 'include' to include path.)include$(BL60X_SDK_PATH)/components/network/ble/ble_common.mk ifeq($(CONFIG_ENABLE_PSM_RAM),1)CPPFLAGS+=-DCONF_USER_ENABLE_PSRAMendif ifeq($(CONFIG_ENABLE_CAMERA),1)CPPFLAGS+=-DCONF_USER_ENABLE_CAMERAendif ifeq($(CONFIG_ENABLE_BLSYNC),1)CPPFLAGS+=-DCONF_USER_ENABLE_BLSYNCendif ifeq($(CONFIG_ENABLE_VFS_SPI),1)CPPFLAGS+=-DCONF_USER_ENABLE_VFS_SPIendif ifeq($(CONFIG_ENABLE_VFS_ROMFS),1)CPPFLAGS+=-DCONF_USER_ENABLE_VFS_ROMFSendif
