【Topmicro Intelligent Display Module】Part 4: Comprehensive evaluation of text scrolling, RTC, etc. [Copy link]

Topmicro intelligent display module has powerful text display capabilities, including static strings, dynamic strings, and switching between Chinese and English.

The display string is designed as follows:

Step 1: Create VP variables

○1 Right-click "String Variable" in the Project Resource Bar
○2 Select "New VP (Automatic)"
○3 Rename VP to "Text Display", as shown below:

Step 2: Create a string control
○1 Right-click "String Variable" in the project resource bar
○2 Select "New VP (Automatic)"
○3 Rename VP to "Text Display",
○1 Click "String" in the toolbar or press the shortcut key Ctrl + T
○2 Create a string control in the PG0000 page
Step 3 Set the string control properties

○1 Set font "32_ASCII_NewSong (16x32)"
○2 Set font color (red = 0xFF0000)
○3 Set background color (blue = 0xFFFF00)
○4 Set VP address 0x000080-text display
Other properties follow default values

The effect diagram is as follows: , the text can be scrolled and displayed, but unfortunately the text can only display 127 characters at most.

Display Chinese characters
○1 The "font" attribute needs to be set to a Chinese font, such as: 24_GB2312_SONG (24x24)
○2 Re-download the project
○3 Write the data "Top Micro" string to VP address: 0x00000080 through the serial port
To display the "Top Micro" content, send the following command:
AA 42 00000080 CD D8 C6 D5 CE A2 00 CC 33 C3 3C
- To display Chinese, the font attribute must be set to the Chinese font library. Displaying other fonts is similar.
- The last character must be the '\0' end character (i.e. 0x00)
- The Chinese characters should be sent according to the selected font library, whether it is GB2312 or GBK, etc.
The corresponding encoding of the Chinese characters.
- In this example, the GB2312 encoding corresponding to "Top Micro" is: CDD8 C6D5 CEA2

Analog clock: RTC can be corrected online

If this Taiwan return timing can be successful, Topmicro will have made a great contribution.
