基于EPS32C3电脑远程开机模块设计
前言
缘起，手头资料太多了，所以想组一台NAS放在家里存储数据。在咸鱼淘了一套J3160主板加机箱，加上几块硬盘组建NAS。
对于NAS，我的需求是不用的时候关机(节省功耗)，要用的时候开机。
网上的开机棒太贵了，也不够安全。
还不如自己制作一个，趁暑假期间(没去实习好亏），刚好手头有一些之前本科毕设用剩下的ESP32C3模块。加上继电器就可以实现远程开机了。
云平台选择腾讯的物联开发平台。无他-因为有ESP32官方例程。
工程修改自乐鑫官方的
Smart Light 使用 ESP32、ESP32S2 配合 腾讯连连小程序 演示了一个智能灯控制方案。
所以这里就不展示其配置过程了，详细内容见Smart Light的README。
接线原理图
IO2–IN
COM–BN
NO–PowerSW
DC±-3V3
DC–GND。
代码
short_switch就是短按。短按开机。
long_switch就是长按。长按强制关机。
GPIO初始化
继电器控制的引脚初始化。对于IO2。
esp_err_t lgpio_init()
{
//zero-initialize the config structure.
gpio_config_t io_conf = {};
//disable interrupt
io_conf.intr_type = GPIO_INTR_DISABLE;
//set as output mode
io_conf.mode = GPIO_MODE_OUTPUT;
//bit mask of the pins that you want to set,e.g.GPIO18/19
io_conf.pin_bit_mask = GPIO_OUTPUT_PIN_SEL;
//disable pull-down mode
io_conf.pull_down_en = 0;
//disable pull-up mode
io_conf.pull_up_en = 0;
//configure GPIO with the given settings
gpio_config(&io_conf);
return gpio_set_level(GPIO_OUTPUT_IO_0,1);
}
app_main.c初始化
static esp_err_t example_driver_init(void)
{
lightbulb_config_t config = {
//1. Select and configure the chip
#ifdef CONFIG_LIGHTBULB_DEMO_DRIVER_SELECT_WS2812
.type = DRIVER_WS2812,
.driver_conf.ws2812.led_num = CONFIG_WS2812_LED_NUM,

return lightbulb_init(&config);
}
控制继电器开闭
简单的控制继电器的操作，通过输出引脚低电平控制继电器闭合。
esp_err_t lightbulb_set_short_switch(bool status)
{
esp_err_t err = ESP_OK;
LIGHTBULB_MUTEX_TAKE(portMAX_DELAY);
s_lb_obj->status.short_on = status;
if (status == true){
gpio_set_level(GPIO_OUTPUT_IO_0,0);
vTaskDelay(1500 / portTICK_RATE_MS);
gpio_set_level(GPIO_OUTPUT_IO_0,1);
s_lb_obj->status.short_on = !status;
}
LIGHTBULB_MUTEX_GIVE();
return err;
}
esp_err_t lightbulb_set_long_switch(bool status)
{
esp_err_t err = ESP_OK;
LIGHTBULB_MUTEX_TAKE(portMAX_DELAY);
s_lb_obj->status.short_on = status;
if (status == true){
gpio_set_level(GPIO_OUTPUT_IO_0,0);
vTaskDelay(15000 / portTICK_RATE_MS);
gpio_set_level(GPIO_OUTPUT_IO_0,1);
s_lb_obj->status.short_on = !status;
}
LIGHTBULB_MUTEX_GIVE();
return err;
}
获取腾讯云指令按钮的值
bool lightbulb_get_short_switch(void)
{
LIGHTBULB_CHECK(s_lb_obj, "not init", return ESP_ERR_INVALID_ARG);
LIGHTBULB_MUTEX_TAKE(portMAX_DELAY);
bool result = s_lb_obj->status.short_on;
LIGHTBULB_MUTEX_GIVE();
return result;
}
bool lightbulb_get_long_switch(void)
{
LIGHTBULB_CHECK(s_lb_obj, "not init", return ESP_ERR_INVALID_ARG);
LIGHTBULB_MUTEX_TAKE(portMAX_DELAY);
bool result = s_lb_obj->status.long_on;
LIGHTBULB_MUTEX_GIVE();
return result;
}
任务切换逻辑
-
获取腾讯云参数后进入相应的函数。
-
设置继电器引脚–控制继电器通。
-
设置继电器引脚–控制继电器断。
-
更新按钮的状态。
-
将值写回参数上传回腾讯云。

基于EPS32C3电脑远程开机模块设计资源-CSDN文库
后记
没时间折腾，直接更改EPS32的官方例程。
仅仅添加了几行代码实现了想要的工程。
原理很简单，代码写得也很简陋，仅供参考。
等有空了(大概率没空），后续添加电脑状态识别(Power LED+和Power LED-)，接入引脚读取电平。
有闲置电脑的同学可以折腾起来，实现NAS远程开机、电脑远程开机、服务器远程开机。
