As I mentioned on another thread, I have been on the hunt for a quadcopter flight controller. I narrowed it down to the MultiWii PRO Ez 3.0. witespyquad.gostorego.com/flight-controllers/multiwii-pro-ez3-0-flight-controller-w-gps-option.html
Here's my problem. It uses i2c. I don't know how to use i2c, and I don't know the different commands for the multiwii.
I found this page with serial protocol, but I don't know if this is what I need or not. www.multiwii.com/wiki/index.php?title=Multiwii_Serial_Protocol
Any help is appreciated. No I do not have the board yet but I am trying to see if this board will work.
All I want to do is get basic commands like forward, backward, left, right, up and down.
Im having a lot of difficulty with this board. Which raises the question again. Is there better and easier out there?
And one thing I thought of is, what if we need to use rc receiver outputs rather than multiwii commands?
Discovered that i2c isn't necessarily what I use.
Wires to the left go to the receiver. If this is correct it means all we need to do is figure out the pwm signal.
How do you mean figure out the PWM signal?
If this board is what I think it is, which is something that is constantly stabilising flight and has the ability for an external controller to tell it where to move (up, down, left, right, forward, reverse, etc) then what you need to do is get all of the datasheets available for it together and study the connections. The datasheet should have all of the correct wiring instructions etc. which will indicate how to connect it to the EZ-B and what controls to use.
That image doesn't really tell us much.
Are these some? http://www.multiwii.com/wiki/index.php?title=Flightmodes
No, that was just information on flight modes. You need the actual installation and operation instructions which will explain what you need to do to use the board, from that you can work out how to use the EZ-B with it.
They do have the download on the info page for the multiwii. I downloaded 2.3. Here's just a list of the file names in it.
If there's something suspicious ill post.
Serial Baudrate:9600(found looking through arduino code)
I posted on the rc forums and here's a response when I asked for serial commands:
"Why not just have the ez-b output a cppm to the MultiWii controller or 4-5 servo pulse (1000-2000us) outputs. If you are looking for modified MultiWii code to accept serial ASCII than go the the MultiWii forum and ask there. The people who write and modify the MultiWii code do hang on that forum."
Should I go to the multiwii forums and look for modified code?
