#The 8th Lichuang Electronic Competition#Digital electronic clock

Note: * is a required field,
please fill it out during the registration stage↓
 
* 1. Project function introduction
Digital electronic clock based on R7FA2E1A72DFL (LiChuang training camp)
*2. Project attributes
The project is public and can be reproduced for free for non-commercial use
* 3. Open source agreement
GPL3
*4. Hardware The
main hardware includes:
1. R7FA2E1A72DFL
2. DHT11
3. Digital tube
4. TP4056
5. AO3401
6. 1N5819WS
7.0603 chip capacitor
8. 0603 chip resistor
9. 0603 chip LED
Note: The current battery pins are too close, you can consider welding the battery pin holder, or loosen the spacing; if the time needs to be more accurate, it is recommended to add an external crystal oscillator (the circuit diagram has been set, see if you need to weld)
*5. Software
The software is mainly provided by e2 studio for development. Currently, it mainly realizes the display of clock, temperature and humidity, and time adjustment
. Note: Since I don’t have JLink on hand, the touch pin is not debugged accurately, and it needs to be long pressed to display the temperature and humidity.
