#The 7th Lichuang Electric Competition# Based on the national technology USB power meter

 
* 1. Project function introduction:
 
USB power meter, supports 0-33V, 0-11A measurement range.
 
* 2. Project attributes
 
are disclosed for the first time, original.
* 3. Open source agreement
 
GPL3.0
 
 
* 4. The hardware part
is based on the ina226 chip for current and voltage detection, and the mcu of national technology is completed. Use LiChuang EDA design, (pd decoy chip is placed, but the software implementation still needs subsequent updates)
 
 
* 5. The software part
 
uses the i2c communication that comes with ina226. This project uses io to simulate i2c, which is convenient for debugging. At the same time, a 0.96-inch screen is used for display
