pin number 9-12 of Arduino UNO R3 is connected with LCD. you just have to write these pin numbers in LCD library functions arguments which tell Arduino that which pin of Arduino
使用Arduino IDE新建一个项目,并编写代码。 示例代码如下: 该代码利用图形库绘制了一些线条和图案,这一讲主要先测试一下LCD驱动,下一讲我会介绍图片的显示。 #include<SPI.h>#include<TFT_eSPI.h>#include<Adafruit_GFX.h>floatp=3.1415926;// TFT_eSPI tft = TFT_eSPI(240, 240);TFT_eSPI tft=TFT_eSPI(...
you can start to develop quickly. At the same time, Arduino has a large global user community, providing an abundance of open source code, project examples and tutorials, as well as rich library resources, encapsulating complex functions, allowing developers to quickly implement various functions. ...
The LCD shield supports contrast adjustment and backlit on/off functions. It also expands analog pins for easy analog sensor reading and display. The LCD Keypad shield is developed for Arduino compatible boards, to provide a user-friendly interface that allows users to go through the menu, make...

Reserve the pins on the Arduino connected to the LCD and used by the library. Reserving prevents other functions from using these pins, giving your library exclusive use of the pins. Send commands, including pin data, to the server using sendCommand. function createLCD(obj,inputPins) try cmd...

前面的博客使用了第一种方式,然后也将C数组存储在sd卡,然后读取sd数据,构建lv_img_dsc_t结构体来进行描述。但是可能是构建的数据不对,或者 lvgl不太兼容这种方式,显示效果不好,图片有很多噪点,所以想了想,当图片数据在sd卡上时,还是的用第二种方式。
The second step was to amend two private functions write4bits(uint8_t) and write8bits(uint8_t) as this is where my code would push data to the PIO to drive the LCD. In fact it turned out that it was simpler just to call the PIO routine from the send function using a new single...
