Hello!
After using the stm32 to communicate with BMP280 through IIC, I have some questions about BMP280 is shown below:
1. What is the accuracy of BMP280 conversion height?
2.Can the three-axis attitude angle and altitude be maintained when the four-axis hovering? (No GPS)
The four-axis itself has three-axis attitude angle and height information, but the XY positioning function is missing
It should be able to maintain roll pitch yaw&height when hovering, leaving only XY drift
If you play with the optical flow algorithm... is it possible to ignore the interference of roll pitch yaw & height changes on the image?
I found some posts on which has detailed info about BMP280, but it seems not very clearly.
Hope for the advice!
Thanks in advance!
