At the beginning, I followed the tutorial, but a problem occurred. It was "send fault". The error message was that the Java class could not be found. Google found some solutions many times, but none of them worked, then, it was a miraculous

Root Folder
This directory should be filled in the Tomcat directory, where the Java project is located, and if it is wrong, "Invalid root" will appear. The Web-inf/flex folder must contain either Flex-config.xml or Services-config.xml. It hints that the directory Web-inf does not exist flex-config.xml or service-config.xml files, and if it is a normal Java project, there will be one in this folder and two files. such as: E:/lcds/tomcat/webapps/
I wanted to learn flex4.0, but there were very few 4.0 pieces of information on the Internet, most of which were 3.0 yuan. So I had to learn 3.0 yuan of space first.
After two days of basic learning, I finally integrated the flex project and Java today. However, it is only the first step. I hope to share it with my classmates, if there is something wrong, please help.

This time I'll talk about how the control flow from the MCU to the LCD is how our bitmap data is displayed on the LCD. Before we learned that the LCD display is implemented by dynamic scanning, each time a full line is displayed, each line in a frame is scanned once, so that there is a circuit to control the output voltage on the row and column, this circuit is the LCD driver, and the output of the driver and the image and the LCD is related to the mode of operation, The driver needs to accept t
