Ok. Here is my latest issue. When I connect via Multiwii my Rx values are jumping randomly all over the place. I am not referring to the graph. I mean where you are supposed to be able to observe the ranges in the upper right corner of the screen. I currently have connected from the nano harness to the Rx:
Ch1 aileron, 5v, and ground
Ch 2 elevation
Ch 3 throttle
Ch 4 yaw
Nano connected to computer via USB
Acc calibration- successful
Mac calibration-successful
Transmitter bound to Rx in PCM mode
Configuration written to Nano as standard PCM successfully.
I have not connected battery power via ESC yet.
What would cause these numbers to jump like that?
Could be one of many issues; can you try to eliminate any other sources of error and disconnect everything but that channel? Can you try the same pin but use a different receiver pin?
I found that the jumpiness was most likely caused by interference.
I had everything all set and I cold get it to arm. Then I discovered when I disconnected the USB that the Nano would not power up via battery. Any suggestions?
Can you post pictures of your wiring?
I have shots with ESC power connected and disconnected showing that it is sending 5v to the Nano. Everything works fine under usb power but once usb is,disconnected it loses power.
Sorry for the late reply.
Can you confirm which unit is used on the Quadcopter ? Is that the one we sent to you lately (brand new PCB) ?
It is the new one. Colin still has my other one.
Can you tell us what is connected to your receiver close to the right end ? The red positive connection seems to be on the same pin row as the Quadrino Nano receiver signal.
Also, the Receiver is usually powered from the Quadrino so the two power wires (black/red) should be connected.
The last time I tried to set up the receiver it was not powering on via the USB port through the Nano and the red/black wires. I had read that this receiver likes it’s own power source. On the far right you see the +5 and ground from an ESC to the receiver. I did not attach the red and black from the nano because I thought that would send juice to the nano from both the receiver and the ESC and overload it. The Nano gets its power from a dedicated esc and the receiver is also getting power from its own esc. There are currently no power leads between the 2, only signal wires from channels 1-4.
I can try again to disconnect the dedicated power from the receiver and connect the red and black wires between the nano and receiver. Wouldn’t the Nano power on regardless if the red and black wires were disconnected? The documentation shows red and black wires on channel 1 with the ail signal wire. I will put them there but not before I disconnect the receiver/esc power connection.
From the picture above, the Positive of the ESC which power the Receiver is providing +5V to the receiver signal wire.
Most Receiver have a row where there are signal than a row of +5V (all connected together) and another with GND (all connected together).
First - Disconnect all the wires from the receiver so the Receiver wiring harness is not connected to anything
Second - Try to power the Quadrino Nano with only the Orange/Red/Black connector for Motor D3.
See if that power the Quadrino Nano.
Disconnected everything except 3 wires from D3 ESC. No power.
This mean the Diode is blown on it as well.
On your picture, you clearly have your Positive and Negative going from the ESC to the Receiver on the wrong pins.
Does your Receiver still power-up if you connect the power to it ?
Usually those are protected against bad wiring.
The receiver does indeed power up with full functionality. I used it with the wires as attached as shown previously. The Nanos only power was from the USB port when I did the MultiWii calibration. The receiver is top pin=signal, middle pin 5v, and bottom pin ground. When I supplied the ESC power to the receiver it was to the bottom 2 pins on the far right. The only wires going to the Nano were channel 1-4 signal wires. I do not understand how applying receiver power to only the bottom two pins could give the Nano a problem. The only connections between the receiver and the Nano were signal wires. The only power wires ever connected to the Nano were the usb first then the ESC power. The red and black wires were never connected. That was the first question I was asked was why the red and black were not connected. Unless I am missing something there is no way that the Nano could have been over powered. I would expect that if I connected the red and black wires to the receiver with esc power and then connected additional power from a second ESC directly to the Nano that I would overload it but that didn’t happen.
The picture is indeed misleading, you probably have the top pin removed and power and ground correct.
You are right, you can’t have the Nano burn by only having the signals connected.
Sorry about asking that but maybe the board you have on hand is not the New one we sent for RMA lately ?
Also, is the Motor wiring harness fully inserted in the socket (we have to ask). We push the side of the connector with a screwdriver or something else to be sure here.
My preferred tool is the paper clip. I am going to double check when I get home from work and do a voltage check by disconnecting the wiring harness from the Nano and see if I have 5v there before I plug it back in. I will keep you posted.
Perfect, we will wait your update.
You are not going to believe this. I ran a continuity check from the esc end of the harness to the nano side of the harness (red and black on the red, black orange wire) no dice. I took apart the black plastic that is attached to the harness (at the esc end)(had to destroy it in the process) and I discovered the red wire was not attached to the appropriate metal lead within the black plastic. I soldered the red wire to the appropriate metal lead and attached the three (now single) metal leads to the esc power and bingo. The three separate leads do not stay in the esc without the black coupler piece though. At least I located the problem. Is it possible to get a harness so I can have a good connection?
So you mean the “Motor Wiring Harness” was problematic and didn’t have continuity from end to end ?
If that’s the case we can send you a set without problem.
