2.2 安装库 打开Arduino IDE,依次打开 工具 -> 管理库… 在搜索框输入需要安装的库名称,找到对应的库,点击安装即可。 本文需要使用的Arduino库如下: 3 LCD驱动的使用和测试 LCD驱动的方式一般是用SPI、并口或者IIC,我这里是以SPI为例。我之前也发布过一篇关于LCD驱动讲解的博客,有什么不懂的话也可以去看一下。
I found a comment block where the author notes potential problems with watchdog timers. It sounds like an ESP8266 is a platform known to work, so I should try that.
while (JpegDec.readSwappedBytes()) { // save a pointer to the image block pImg = JpegDec.pImage ; // calculate where the image block should be drawn on the screen int mcu_x = JpegDec.MCUx * mcu_w + xpos; // Calculate coordinates of top left corner of current MCU int mcu_y ...

语法: do { // statement block } while (condition); //注意分号不能丢 条件condition是一个布尔表达式:只有true 或false两种结果。 例子代码 : do { delay(50); // 等待传感器进入稳定状态 x = readSensors(); // 读取传感器的值 } while (x 100); //x小于100时,条件为真,进入循环 53 3.4 控制...

Serialobject works much the same way as on a regular Arduino. Apart from hardware FIFO (128 bytes for TX and RX) HardwareSerial has additional 256-byte TX and RX buffers. Both transmit and receive is interrupt-driven. Write and read functions only block the sketch execution when the respecti...
The ESP32 comes with 2 Xtensa 32-bit LX6 microprocessors: core 0 and core 1. So, it is dual core. When we run code on Arduino IDE, by default, it runs on core 1. In this post we’ll show you how to run code on the ESP32 second core by creating tasks. You can run pieces ...
Copy the code into the Arduino IDE. Compile and run the program. Start the serial monitor to see the output.void setup (void) { Serial.begin(9600); Serial.println("Arduino for loop"); for (int i=0; i<10; i++) Serial.println(i); } void loop(void) { } ...
I’m going to build an Arduino ATmega1284P circuit on a breadboard, burn a bootloader, and upload sketches to it, all using the Arduino 1.0 IDE. This will all go better if you have done it once first with a regular ATmega328P. Doing these things on that chip is well-documented, and...
