Ai-WB2-32S gpio驱动RGB灯 ​

前言 ​

本期文档介绍使用库编写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） ​

📜 点击展开：#
bash
#

## 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 := evb

export
 PROJECT_PATH PROJECT_BOARD

#CONFIG_TOOLPREFIX :=

-include ./proj_config.mk

ifeq ($(origin BL60X_SDK_PATH), undefined)
BL60X_SDK_PATH_GUESS ?= $(shell
pwd
)
BL60X_SDK_PATH ?= $(BL60X_SDK_PATH_GUESS)/../../..
$(info ****** Please SET BL60X_SDK_PATH ******)
$(info ****** Trying SDK PATH [$(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） ​

## Troubleshooting

For any technical queries, please open an [issue](https://github.com/Ai-Thinker-Open/Ai-Thinker-WB2/issues) on GitHub. We will get back to you soon.

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） ​

c
#
include

<stdio.h>

#
include

<string.h>

#
include

<FreeRTOS.h>

#
include

<task.h>

#
include

<bl_gpio.h>

#
define
 GPIO_B_PIN 3

#
define
 GPIO_R_PIN 14

#
define
 GPIO_G_PIN 17

void

blink_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
);
    }
}

void

main
(
void
)

{
    xTaskCreate(blink_test,
"blink"
,
1024
,
NULL
,
15
,
NULL
);
}

第8步 编写bouffalo.mk文件（代码如下） ​

📜 点击展开：#
bash
#

## "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_PSRAM
endif

ifeq ($(CONFIG_ENABLE_CAMERA),1)
CPPFLAGS += -DCONF_USER_ENABLE_CAMERA
endif

ifeq ($(CONFIG_ENABLE_BLSYNC),1)
CPPFLAGS += -DCONF_USER_ENABLE_BLSYNC
endif

ifeq ($(CONFIG_ENABLE_VFS_SPI),1)
CPPFLAGS += -DCONF_USER_ENABLE_VFS_SPI
endif

ifeq ($(CONFIG_ENABLE_VFS_ROMFS),1)
CPPFLAGS += -DCONF_USER_ENABLE_VFS_ROMFS
endif

二、编译并烧录 ​

第1步 进入~/Ai-Thinker-WB2/applications/get-started/gpio目录 ​

cd ~/Ai-Thinker-WB2/applications/get-started/gpio

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 ​
