打开导出的文件并将十六进制代码复制到Arduino IDE。 x和y是图像的位置。 w和h是图像的大小。您可以在最后一个输入中更改图像的颜色。drawXBitmap(int16_t x, int16_t y, const uint8_t *bitmap, int16_t w, int16_t h, uint16_t color),xbm是一种简单的双色图片位图格式,在早期的cgi中运用较多...
In this tutorial, you’ll learn how to use ESP32 interrupt pins in Arduino Core. We’ll also discuss how to use interrupts and write your interrupt service routine (ISR) for ESP32 external interrupt GPIO pins. Then, we’ll move to the Arduino Core libraries that implement drivers for the...
setup( ) :In Arduino IDE, setup function is used for declaration or initialization. A pinMode function is used for declaration of digital pins. So it will be defined inside setup function. It will become more clear when you see the example code at the end of this article. Loop( ) :In...
这是基于我的硬件的配置文件 // USER DEFINED SETTINGS// Set driver type, fonts to be loaded, pins used and SPI control method etc/// See the User_Setup_Select.h file if you wish to be able to define multiple// setups and then easily select which setup file is used by the compiler./...
However if we simply intialise two instance of the SPI class for both of these buses both can be used. However when just using these the Arduino way only will actually be outputting at a time. Logic analyser capture is in the same folder as this example as ...

Which GPIO pin can be used as a digital input-output pin? Which GPIO pin can be used as an analog pin? And which pin should not be used to use this board safely? You will get the answer to these questions in this article. So now let’s begin with the introduction of GPIO pins ...

In this section, I’ll give you a step-by-step approach to using ESP32 I2C in Arduino IDE for your project code. Step1–Include the Arduino Core I2C wire library #include <Wire.h> Step2–Define the I2C_Frequency and GPIO pins to be used for (SDA & SCL) lines 1 2 3 4 #define ...
