The main recording paper Devine screen using the serial port
Doing project uses a serial Devine screen, less information on the Internet, starting more difficult, after his own fumble after the start to give you a simple way.
Screen model DMT48270T043, kernel M100 (serial screen listed earlier, and now DWIN are DGUS screen, and note that the two are different), 8pin interfaces, 5V, DIN, DIN, DOUT, Busy, GND, GND , the two DIN Unicom, common ground GND, it is generally used, can be connected directly to 5V, and GND can be a DIN. Busy is whether the reminder data buffer full state, to prevent data loss occurs. Specific parameters of the screen can be found in the instruction manual for the model, not repeat them here.
Debugging aids:
Devine debugging aids 6.1
Methods of test screen Description:
May be used to TTL USB adapter plate, the adapter plate is connected to TXD Devin screen DIN, RXD then the DOUT Devine screen, while using direct power supply adapter plate.
It should be noted , have TTL level and RS232 level on the back of Devin screen jumper selection , if you use TTL level need to back screen corresponding jumper shorted. After connecting you can directly use the computer, the serial port can be used to debug a screen by Devin 6.1 debugging assistant directly.
First need to Devine screen handshake, the handshake that: select the correct port number, and set the baud rate is 115200 ( It should be noted , for the baud rate settings, on the back of Devine screen also has jumper selectable baud rate options, 1,921600,2,115200, general factory default is 115200), set up after the handshake will be able to click a button, and if successful handshake Devine screen, the software will automatically pop-up dialog box prompts handshake success.
Which can then be directly manipulated by a number of options for debugging aids inside Devin screen, including screen colors, text display, load images, display clock and so on, you can explore on their own. In particular, we can familiarize ourselves with the configuration parameters of the toolbar terminal, which is the initial configuration screen Devine, as well as the basic configuration, the problem no longer respond to instructions issued after touching the screen, for example, if they are in use, please pay attention to the initial configuration parameters.
It should be noted that without Devine debugging assistant, then assistant general serial debugging is also possible, but the first screen of the operating Devine hexadecimal command strings can only be achieved by. Specific commands described with reference to Di industrial serial HMI screen instruction set 2.4. Since we use the serial port to screen all its operations through the MCU control panel, and therefore familiar with the operating instructions or consult the documentation to learn, very helpful for project development.
For questions on how to download the font Devine screen, I have to share in another blog post.
