#The 8th Lichuang Electronic Competition# Desktop electronic clock design based on Renesas

Note: * is a required field,
please fill it out during the registration stage↓
 
* 1. Project Function Introduction
The desktop electronic clock design based on the R7FA2E1A72DFL chip displays time, temperature, etc. through a four-digit 0.56-inch common cathode digital tube, and uses a DHT11 temperature and humidity sensor to collect ambient temperature and humidity. The reset button, serial port circuit, and SWD download circuit are all led out for easy download and debugging.
*2. Project Properties
1. Main control chip: R7FA2E1A72DFL;
2. Power interface: TYPE-C, 2Pin plug-in;
3. LED: one power indicator light, one charging status indicator light;
4. Buttons: one reset button, one BOOT button, and four function buttons;
5. Debug interface: SWD download debug interface and serial port download debug interface are both led out using a 2.54 pin header interface;
6. Peripherals: one 0.56-inch common cathode digital tube, one DHT11 temperature and humidity sensor, and one passive buzzer;
7. Shell: Acrylic shell is used.

Please enter the content of the open source agreement...
 
Note: Altruism is self-interest, please read the following content carefully.
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 deletion, 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;
the project should choose an open source protocol that suits it. If the project references other open source projects, the source should be indicated and the original author's open source protocol regulations should be followed; original projects are recommended to use the GPL3.0 open source protocol;
functions implemented by directly citing the original circuit or original code of the open source project cannot be used as the core function of your own project, and functions directly implemented by using general modules on the market cannot be used as the core function of your own project.
