How many calories did Lao Ba eat today?

Official persecution from the production team of "Too Many Noble Female Leads"!
A mysterious girl ate 10 kilograms of carbs but only gained 3 kilograms!
We still don't know how much Lao Ba can actually eat!
 
Okay, jokes aside, the official website of the "Noble Female Leads" anime provides a special page showing exactly how many carbs Lao Ba ate, which makes you smile and makes you want to replicate it. (Committee Independent Investigation of Hachina Mi Anna Carory Message | TV Anime "Too Many Noble Female Leads!" Official Website (makeine-anime.com), connection speed is relatively slow)
So, color silkscreen + OLED screen is the best combination.
 






The front of the board has a webpage layout, displaying numbers or other information through a 128x32 OLED screen; orange LEDs indicate the active episode; buttons allow you to select whether a particular episode is included in the statistics.
All control circuitry is concentrated on the back, centered around the ESP32-C3-mini-1 module, including power supply, communication, reset and download, LED driver, and OLED driver.
 
 
【About the Replica】
=====Program Description======
Developed using PlatformIO, the OLED uses software I2C driver. It can be easily converted to Arduino code.
The attached code only includes the demo shown in the demonstration video; not all functions are implemented.
Please refer to the circuit diagram for serial port pin definitions. When downloading, you need to press and hold the RST and BOOT buttons, then release RST first, then release BOOT.
Originally, we planned to add serial port settings, Wi-Fi connection, and online data acquisition functions, but since the hardware sample was almost finished and almost all samples were released, we abandoned this plan and directly wrote the data into the program.
 
=====Circuit Description======
The OLED screen is a 14-pin SSD1306 128x32 module, using the I2C protocol. The peripheral circuitry has high requirements and components cannot be arbitrarily changed.
The orange LED brightness is low; it is recommended to reduce the resistance values ​​of R8~R11.
The LDO is not the 1117; the pin definitions are different. I didn't notice this when designing, which caused me to waste several days buying a new chip.
Only one side of the Type-C connector was used, and the ESP32's USB virtual string recognition failed; I haven't investigated why. Also, the CC cable cannot be used, as it may not provide power.
 
======Other======
LCSC EDA requires color silkscreen printing to preview the effect; please be sure to select color silkscreen printing when ordering.
To ensure it's not contaminated, please minimize the use of flux and heating elements.
 
 
Finally, let's all say: Old Eight has a big stomach, no need for much salt!
