【Digi-Key Follow me Issue 2】Task 1: Control the screen to display Chinese [Copy link]

 

First of all, I am a student at Zhejiang Gongshang University. I saw Brother Long's video on B Station and was quite interested in it. After waiting for 2 months, the board finally arrived. I would like to thank the EEworld community and Digi-Key Electronics for giving me this opportunity. The board is really very beautiful and exquisite.

Task 1: Control the screen to display Chinese (mandatory task)
Complete the screen control and display Chinese
Matched device: Adafruit ESP32-S3 TFT Feather

Task 1 Preliminary preparations:

1. Espressif Burning Tool
2. Factory firmware Adafruit_Feather_ESP32S3_TFT_FactoryTest.bi
3. CircuitPython Firmware
4. IDE (I use Thonny)
5. Font Files

Here are the specific steps:

1. Connect the board to the computer. When you connect the board for the first time, the original interface will be displayed, which contains information such as battery voltage and power.
2. Next, press the ret button twice to enter DFU state
   

3. Then a USB drive named FTHRS3BOOT will pop up on the computer.
4. Drag the pre-downloaded circuitpython firmware into the USB drive. As long as the file is copied, the burning is successful. No other software or other operations are required. It is more convenient than other boards I have played with.
5. Because we need to display Chinese, we need to call two library files, adafruit_display_text and adafruit_bitmap_font, drag them to the lib folder under FTHRS3BOOT
6. Next, create a new folder in FTHRS3BOOT, name it fonts, drag the downloaded font file into it, pay attention to the size, and do not use fonts that take up too much space.
7. The next step is to write the program. The program is very simple, but the challenging part is to adjust it slowly, such as font, position, color, etc., to achieve the best effect.

   import board
   from adafruit_display_text import bitmap_label        //导入库文件
   import terminalio
   from adafruit_bitmap_font import bitmap_font
   
   font = bitmap_font.load_font("fonts\wenquanyi_10pt.pcf")//定义字体
   color = 0x11ff11//定义颜色
   
   text2 = "浙江工商大学"//文本内容
   scale = 2//定义字体大小
   
   text_area2 = bitmap_label.Label(font,text=text2,scale=scale)
   text_area2.x = 10//控制文本的位置
   text_area2.y = 30
   board.DISPLAY.show(text_area2)
   
   while True:
    pass

Drag the downloaded font file in, pay attention to the size, don't use a font that takes up too much space, okay.

It is indeed difficult to choose the font. Too small is hard to read, too large is too big to download.
