How did you make the connections from the smartphone to the quadcopter?

Thank you and Kudos on your accomplishment.

copterrichie

May I ask if we can reserve the follow MSP code for Airspeed which would be used in connection an Airplane or Flying wing?

Example:

Code: Select all

MSP_AIRSPEED   125
MSP_AIRSPEED_CALIBRATE 216

Thank you.

copterrichie

It would be nice to have a heartbeat with basic telemetry data, would cut down on traffic too.

copterrichie

Add to the above, much of the development on the 8bit platform has almost come to a stand still. The few people that are still developing are fearful of being BASHED in my opinion.

copterrichie

That makes total sense about the loop time, it has been a pain in the .... for sometime now.

Is Baseflight DEAD? If so, others should be able to pick up the ball and run with it right?

copterrichie

My mistake, it is not that easy. Here is some information from the datasheet, seem if the mpu6050 is not in the master mode, it is in the pass-thru and this explains why the MAG still answered up. Sorry Auxiliary I2C Serial Interface The MPU-60X0 has an auxiliary I2C bus for communicating to an off-...

copterrichie

If the MAG is still answering, then it is connected directly to the i2c bus and not to the mpu6050 aux.

But I tested on my AIO board direct and HMC5883 is still answering..
Sorry it don't seem to work for me anyway.

Did you try remarking the following out for your board?

Code: Select all

#define MPU6050_I2C_AUX_MASTER // MAG connected to the AUX I2C bus of MPU6050

copterrichie

If the MAG is connected via the mpu6050 AUX, then it is not connected on the main i2c bus, just disabling the aux master should do the trick. It will just sit there and draw power but not do anything.

copterrichie

Just thinking out loud here, if the MAG is connected via mpu6050 aux, you MAYBE able to remark that out in the def.h #define MPU6050_I2C_AUX_MASTER // MAG connected to the AUX I2C bus of MPU6050 and to set the MAG in the Config file. /* I2C magnetometer */ //#define HMC5843 //#define HMC5883 //#defi...

Maybe it is time to start bread boarding again until some vendor jumps onto the bandwagon.

copterrichie

Maybe of no interest however, there were a bunch of crappy cheap MPU6050 on the market. Had a few failures myself.

copterrichie

Even tho you have a MAC, it still requires installation of the USB Driver.

The original intent of the fail-safe was to prevent fly-aways when using the traditional RX (no ppm). nothing more and nothing less. There has been lots of talk of having it do RTH and auto-landing but nothing has been done.

copterrichie

Where is the unity folks? Ha, flew out the windows I assume.

copterrichie

TC has a lot going on as a one man operation. Sadly however, he does not allow anyone to help him unless they conform to his standards.

copterrichie

I was toying around with the configuration on the APM and noted it also had an auto tune feature. I have no idea where it is within the code but APM is also open source. You might have a look around to see what you can see.

copterrichie

The cleanliness of code is very subjective and a matter of opinion. I know of MAJOR corporations that have a two stage process, get the code working, then clean up / make it more efficient.

The favorite bookmark link is gone, you have to bookmark the direct link now. Now sure just how much longer Google will support Development, seems to be on a major decline..

copterrichie

Open Source right?

copterrichie

Sidebar: There was some talk earlier of porting the MWC code to the APM hardware, I think the only real issue is, the APM uses SPI sensors.

Here is a preview of my version of the MultiWii Airplane, she will be using an ATMega328P with a MPU6050 for starters. Once the design is perfected, I May use the NAZE32 I have sitting on the shift once I am able to compile Baseflight or Harakiri on my Linux box. I am using a special modified Bicopt...

copterrichie

I had a cheap MPU6050 on its own breakout board that totally and completely failed in-flight. Talk about one hell of a crash but the good news is, I replaced the board and all was good to go with some repairs to the frame of my copter.

DUE for 23.75.

Awesome Job, I recently ordered a DUE for testing.

I use these mega shields available on eBay, maybe you can used one for this project.

SxpscquBIo4 I may be an odd egg in that I don’t like to use an IDE when developing uC firmware. Generally I rock the text editor and a makefile for 8-bit, adding OpenOCD and GDB when working with ARM. I probably shouldn’t be surprised that there is already OpenOCD support (and by extension GDB supp...

Mainly, you need to change the baud rate of the BT connected to the FC, the BT on the Macbook will adjust automatically when the IDE sends the data. How to change the Baud of your BT connected to the FC, you will need to check the BT manufacture's manual for it. Not trying to discourage you here how...

copterrichie

You will need to change the BT speed to 19200/57600 (don't recall which) baud and because many of the BT adapters do not have the DTR/CTS pins connected, at the point when the IDE starts to send the data, you will have to press the reset button providing there is one on the board. I personally have ...

TC, does this mean that We MAYBE able to use the Arduino IDE to compile Baseflight in the near future?

The following video is the most successful implementation of an ultrasonic sensor on a MWC. Take note, the copter is always below eight feet (2 meters - 2.5 meters)

copterrichie

Maximum RANGE with any accuracy(2cm) is 2 meters, any over that is junk readings. Best of Luck.

copterrichie

I hope the best for you on this project. I have been working with some HC-SR04 (four) on a ROVER and the best accuracy is 2 meters. Not very good for Altitude holding in my opinion.

Yes, that's right. But technically I don't see a problem to use D12 as Throttle. Agreed, I never played with the Throttle Channel but D12 is on a difference Port, B to be in fact.

Not all the pins are equal in their functionality.

I heard from the vendor and they are sending a replacement esc and I ordered another one from a different source. Maybe I was too quick to judge, lets see what happens upon receipt.

copterrichie

These EMAX QUATTRO 25A x4 in 1 Brushless Speed Controllers ARE JUNK, I would not recommend them at all. Within 30 Seconds of Initial test without props, one of the four ESCs burnt. Please save your money and get some standard ESCs. https://dl.dropboxusercontent.com/u/266727/Pictures/Builds/DSC02409-...

copterrichie

Just curious, any updates to this development?

copterrichie

The transitioning is difficult for any VTOL including military versions. With this said, Kudos to your accomplishment.

copterrichie

Not directly related but along the same line: http://www.gadgetify.com/autonomous-dro ... r-filming/

copterrichie

I am developing a HD video downlink using a Raspberry PI and Camera. The Latency is very tolerable however, I have yet to flight test the system.

copterrichie

Understandable, I was just toying with you. As mentioned above, the BeagleDrone maybe an option especially in a package deal of some sort.
