大部分Arduino开发板上面就有一个LED灯连接到PIN13。如果你不连接硬件就运行这个例子,你应该也可以看到LED闪烁。 原理图 你插好电路板,连上电脑之后,打开Arduino IDE软件,输入以下代码。 样例代码 以下代码用 millis()函数来闪烁LED灯,如果开发板开始运行,会返回微秒的数值 ...
In the previous tutorial, we learned to blink LED by using the delay method. That method blocks Arduino from doing other tasks. In this tutorial, we are going to learn another method to blink LED without blocking other tasks. The detail instruction, code

So I assume you are using arduino-esp32 as a component with your own sdkconfig settings? Let's say portTICK_PERIOD_MS = 10 and you call delay(9). Do you really want to block and spin for 9ms? with current core7dbda4 to console i = 0, actual sleep = 0ms ...
所以去网上查了,说millis()能代替delay执行延时的功能。但是却没有找到如何使用。。所以再次请教各位大神了 杰克船长1412 默默无闻 1 millis()返回arduino从启动到当前所经过的毫秒数,大约42天后溢出。如果将当前的时间记录下来(时间戳),记为timeStamp,然后在之后某一时间进行一次(millis()-timeStamp)计算,就...
void initSystems(void *param) { esp_task_wdt_add(NULL); // SPIFFS unsigned long now = millis(); while (!SPIFFS.begin(true)) { while (millis() - now < 100u); } esp_task_wdt_reset(); now = millis(); while (!Wire.begin()) { debug("Failed to start Wire"); while (millis(...
Usingmillis()admittedly takes a little bit of extra work when compared to usingdelay(). But trust me, your programs will thank you for it, and you can't do multitasking on the Arduino without it. If you want to see an example ofmillis()used in a real-world Arduino project, check out...
