Hi every one,My name is prasad,an Engineer (Electrical) from Andhrapradesh India.
“My past is everything I failed to be.”
I always love to work with electronics, it has taken years to learn all the stuff that i'm going to post in my blog.hopefully if you are interested to learn,it will take just a while to learn.
On openpilot and open the firmware tab. Click rescue then plug in your Quad to computer via USB (no power)
Click open and select .bin that you downloaded.
Click the checkbox, I know what I’m doing!
WAIT TILL 100%
IMPORTANT! Leave USB plugged in and power the board via esc input
Click boot (in same firmware window), motors will beep and wait till blue light on the cc3d is steadily blinking
Power your Quad and plug usb back in now.
Click connect. (if it fails, try changing the port)
Congrats! You now are on Cleanflight. To connect your Quad to Cleanflight you always need to use power now, plug in your battery!
Place Quad on flat surface and under setup, click calibrate accelerometer.
Change minimum throttle to 50 above what your receiver shows on Receiver tab. (usually 1000, so put 1050)
Click Save and reboot
Now goto your PID tuning.
Change PID Controller to LUXFloat
Now change the following Change roll rate to 0.70 Change pitch rate to 0.70 Change YAW rate to 0.40 TPA should be 0.00 TPA breakpoint should be 1500
Now goto receiver tab, and check all your transmitter channels are correct, they usually are different and you will need to reconfigure.
I have the FlySky FS-R6A receiver, so for me, I had to move the following. Ch 1 moved to Ch3 Ch 3moved to Ch 5 Ch 4 moved to Ch 1 Ch 5 moved to Ch 4 (You may need to swap Ch 2 and Ch 4 around if your pitch and roll is incorrect.
Now on the right (still receiver tab) change throttle to 0.50, throttle EXPO to 0.00, RC rate to 1.00, RC expo 0.00 – Save
Now you want to set up your AUX Switches, open the Modes Tab.No mode selected = ACRO+ / Rate mode by default.Altitude mode = Angle Mode Rattitude mode = Horizon Mode If you your switch only has two positions it would look something like this. 0 = Horizon Mode 1 = Acro/RateIf you have a switch that has 3 positions it may look like this. 0 = Angle 1 = Acro/rate 2=Horizon
If you have more than six channels you may want to setup ARM as a switch, as well as a buzzer, or lights.
Now save your settings. By moving your switches you should be able to test the setup. Green = mode activated, grey means Acro/Rate mode.
Now we need to calibrate ESC, go to the motor tab. remember, you should have removed props at the start, if you didnt, DO THIS NOW.
Slide Master to MAX
Plug in battery, wait for beeps.
Slide Master to MIN
ESC Calibration is now complete, however you must test that it has worked corectly. Arm copter, and all motors should spin at 0 throttle. If only some do, you need to redo the above steps until they are all spinning correctly.
