#The 8th Lichuang Electronic Competition# Ink screen clock

The hardware has been successfully verified, and the serial port download problem of the old version has been corrected.
The current progress: debugging iic, eerom, adc, buzzer
* 1. Project function introduction
  Based on the R7FA2E1A72DFL chip, the desktop ink screen clock design uses a 2.9-inch 2-color ink screen to display time, temperature, etc., and uses an aht20 temperature and humidity sensor to collect ambient temperature and humidity. The reset button, serial port circuit, SWD download circuit, and all io have been brought out to facilitate download, debugging and expansion.
 
 
*2. Project attributes
 
* 3. Open source agreement
Embrace open source and give the project unlimited value. It is recommended that more than 80% of the core functions of the project be open source;
if a part of the function is irreplaceable and the project cannot solve the corresponding problem after deleting it, then the function implemented by this part is the core function of the project; for example, if an electronic load is designed and a host computer software is designed to monitor power changes, the electronic load is the core function and the host computer software is an auxiliary function; for example, an isolated 485 module is used in the electronic load to communicate with the host computer, then the communication function implemented by this 485 module is an auxiliary function; if the project references other open source projects, the source should be indicated and the original author's open source agreement should be followed
; original projects are recommended to use the GPL3.0 open source agreement;
functions implemented by directly referencing the original circuit or original code of the open source project cannot be used as the core functions of your own project, and functions directly implemented by using general modules on the market cannot be used as the core functions of your own project. Please fill in the following in the competition stage↓ *4. Please enter the content for the hardware part ... Note: It is recommended to use Jiali Chuang EDA. If you choose other EDA tools, please upload the schematic diagram in PDF format, the PCB drawing in PDF format, and the PCB file in Gerber format in the attachment. Here you can explain in detail the implementation principle and mechanism of your project, precautions, debugging methods, testing methods, etc. It is recommended to introduce your ideas to others in the form of pictures and texts. *5. Please enter the content of the software part... Note: If your project involves software development, please upload the corresponding engineering source code in the attachment. Here you can explain in detail your software flow chart, functional module block diagram, explanation or popular science of related algorithms, source code structure, compilation environment construction and configuration, source code compilation method, program burning method, etc. It is recommended to introduce your ideas to others in the form of pictures and texts. *6. BOM list The battery uses 502540 specifications, 3.7v battery connection plug, plug specification "SH1.0" 1mm spacing 2pin horizontal connector, pay attention to distinguish polarity before connection. The battery wire is wound down and leaned against the side. Then cover the back cover. The buttons on the back cover are boot and rest buttons, which are convenient for debugging. The shell will be placed in a shell without debugging buttons. *7. Competition LOGO verification * 8. Demonstrate your project and record it into a video upload function to be improved. At present, it can only display date, temperature and humidity, and set time and other simple functions, and only release the screen demo. All source codes will be released after improvement. The shell file will be released after being sorted out, and the bom table will be released after being sorted out.
