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(...
之前在淘宝买了一块2.4寸240×320像素的SPI串口屏(使用的驱动芯片是ST7789V),下面尝试使用TFT_eSPI库在Arduino+ESP32上快速点亮这个屏幕。屏幕上有8个引脚,我对应的接线如下(我买的这个屏幕背光线不接悬空的话屏幕不会亮) 在Arduino的库管理器中下载TFT_eSPI库,之后在该库的路径下(C:\Users\xx\Documents\Ardui...

1,lvgl采用Arduino_GFX Library库来移植到TFTlcd上时,显示会畸变,颜色不对(我的是这样的)。 2,所以要使用lvgl,得用TFTe_SPI库,但是该参考项目是基于Arduino_GFX Library库的,我们的移植过来。 视频格式采用MJPEG,这样更快点,视频支持的帧率会更高。 视频播放是在前面博客搭建的框架下加入的。 移植: 1,参考前面...
