APM 2.5 2.6 2.8 Optical Flow Sensor Optical Flow V10 No GPS Point
Item Name:Optical Flow V10
To improve the precision when you can't use GPS, APM: Copter now support optical Flow V1.0 based on mouse sensor.
Sensor can only work under good lighting condition
Using fixed foucus lens, so it cannot focus lens of objects that within 30cm
Rotate sensor will make sensor in disorder
Connecting sensor to APM2.5, APM2.52, APM2.6, APM2.8 all can be used
As shown below, connect VCC, GND, MISO, MOSI, SCLK and NCS pins
The default installation is shot down, pin forward
Power Off the back of the board MISOLVL jumper, re-welding work so MISO pin at 3.3v. This is very important to ensure that the optical flow sensor does not interfere MPU6000.
Update testing sketch to APM:
If you use APM2, you can download hex files at download zone, then use Mission Planner's original setting> Install Firmware> Load custom firmware connections to your APM2
If you use APM1, you need to open Arduino IDE and loading AP_OpticalFlow_test.pde, and update it to your APM1
Using serial port monitor or AP Mission Planner terminal to connect with APM
Input 'c', to make sure sthe sensor will respond APM
Input 'm&apos, start the front or back camera, check the changes of X Y value. If ther is no change, rotate the lens to adjust focal distance
you can track your packages after an order has shipped.
