Original question:

TIDA-010042 ： MPPT charge controller reference design for 12- and 24-V solar panels

TIDA-010042: Where is I2C part of code?

Part Number: TIDA-010042


Greetings,

I am working on design "www.ti.com/.../TIDA-010042" given by TI. In the schematic there are 2 sensors- TMP303CDRLR(for temperature sensing) and OPT3001DNPR(for sunlight intensity). At same link under software link I found the software for given design. In the code in main() Init_I2C(); function was commented and  there is no use of  I2C related variables in code.

My queries are:-

(1) Why exactly we want to calculate temperature and sunlight intensity using stated sensors? I am aware that these factors affect output power of solar panels but anyhow we are calculating  MPPT then what is the need of monitoring temperature and sunlight intensity?

(2)If monitoring temperature and sunlight intensity is important then where to find the complete software related with this design ? If not important then can I remove 2 sensors from the design?

Thanks

Best Regards

    Hi Bhushan,

    These additional sensors are provided in the circuit for applications that may need them. For example, if a charging voltage correction based on ambient temperature is needed, the temperature sensor can be used. The current software does not include them.

    You can remove these components without affecting the basic functionality of the circuit.
