ESP32-Kconfig配置

1. 新建Kconfig.projbuild文件

2. 写入配置项

1. 新建menu

menu "点灯配置"

endmenu

运行 idf.py menuconfig，结果如下
powershel

vscode

可以看到，power shell中文支持上有乱码，所以接下来选择英文
2. 配置menu，新增3个配置项

menu "WS2812"

	config LED_GPIO_NUM
		int "gpio pin"
		prompt "set esp32s3 board ws2812 GPIO"
		range 0 48
		default 48
		help
			This is help message
	
	config LED_RMT_CHANNEL
		int "channel"
		prompt "set esp32s3 ws2812 pwm channel"
		range 0 3
		default 0
		help
			This is help message
	
	config DELAY_TIME_MS
		int "period(ms)"
		prompt "set esp32s3 ws2812 blink period"
		range 0 2000
		default 1000
		help
			This is help message

endmenu

运行 idf.py menuconfig，结果如下

进入配置项

按？查看help帮助信息


修改闪烁周期值

按enter 修改完成

运行vscode，结果如下

3. 编译

1. 查看sdkconfig文件，已经写入了3个宏定义
   
   那么在C代码中就要替换这几个宏定义

}

运行结果：

;
vTaskDelay(CONFIG_DELAY_TIME_MS / portTICK_PERIOD_MS);
}
}

运行结果：
