The idea for this project comes from the SPA algorithm transplantation by forum friend 54chenjq. I still don’t understand this algorithm, and it actually involves a lot of things. The benefits this algorithm can bring are also obvious. The obtained solar azimuth and altitude angle errors are also within 1%. It has applications in solar panel tracking, object light avoidance, etc.
This design only implements the establishment of the basic framework, such as protocols, business processing, task processing, upper and lower computer interaction data, etc., and makes abstract interfaces one by one, and calculates the solar altitude angle and azimuth angle at this time through SPA. Simply use the obtained azimuth angle, altitude angle, etc. to convert the PWM duty cycle to control the corresponding rotation of the servo. There is actually a lot that needs to be done.
