I recently aquired a 24GHz presence module, and read the docs and tried an tested a bit. But i find the provided data is not sufficient and the library also lacks some functions. @Seedstudio here are some Questions:
- In the manual and datasheet interface 2 is described to be re definable but no information about how is provided.
- A function to send data packages is also missing in the library.
- Is there a larger datasheet / manual for the mic radar chip and or this module used so i can try to figure this out myself?
- How will the gear setting affect the range
- Which pins are only 3.3v tolerant or are all pins 5v tolerant
