Eachine1 Apm 2.5 2.6 2.8 Optical Flow Sensor Optical Flow V10 No Gps Point

APM 2.5 2.6 2.8 Optical Flow Sensor Optical Flow V10 No GPS Point Description: Item Name:Optical Flow V10 Material:Metal Features: To improve the precision when you can't use GPS, APM: Copter now support optical Flow V1.0 based on mouse sensor. Package included: 1x Optical Flow Sensor Known Issues: 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. Testing sensor: 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
