LCSC* Diwenxing Voltage and Current Meter Training Camp

Compilation of Mishaps During the Replica Process (Currently Stuck on Experiment 5)

2. Panel Printing Notes
2.1 If the panel printing is done as a line drawing with light transmission, you need to clearly tell customer service which side will be the display side so that customer service can make a left-right mirror image
3. OLED Transplantation Notes

3.1 It was mistakenly believed that the pins of the Diwenxing development board were also numbered, but this is not the case. As shown in the figure, B10 refers to GPIOB10, not number 15 in the EDA design software
(when I2C is outputting normally, the SCL voltage is approximately 0.05V, and the SDA voltage fluctuates between 0.05V and 3.3V [because of communication]).
      Figure 3.0 shows the PIN pin diagram of the development board .
Figure 3.1 shows the corresponding PIN pin diagram.
      Figure 3.3 shows the misleading serial number. Figure
3.2 shows the source code of my open-source temperature and humidity sensor project (https://oshwhub.com/lingyundesign/shengsirui-pre), which uses Python to implement Chinese characters on an OLED display. The non-model extraction method uses GB font library extraction (all attachments are publicly available and can be directly downloaded).
Here, I will attach the OLED Chinese character display implemented in C language (model extraction implementation, font library extraction has not yet been learned), see the attached source code, which can be directly downloaded.
