I'm currently awaiting the arrival of a busted gimbal for just that purpose.
I forgot. On the wire it is packed doubles, then floats, then uint32, then uint16, then uint8. CRC hash is calculated after reorder, so....
Which makes more sense since it makes the target system id Decimal 0 (broadcast) and component ID decimal 1 (Autopilot)
So are you talking about the board behind where gopro sits?
Watching this because I have a DIY platform with a cube 2.1 and needing a gimbal
I have one guys, just tell me what you need
Closeup photos of all the numbered ICs of all the chips on the uppermost pcb, especially anything that looks like an accelerometer. Close up pictures of all the major ICs on the teardrops shaped sub-pcbs.
Is there anything on the back of that PCB you've got such lovely pictures of?
I can read the chip numbers on the big board, do you mean on the shaft?
I can't read the numbers on U10 (lower right corner, looks like about 4x4mm) can you?
Circle them in the pic and I will break out my magnifier
Nothing on the backs of the tears, might could tear one open
I don't think this is much better?
Well there it is
MPU-6000, Motion Sensor - 6 Axis, TDK InvenSense
THAT is where it was hiding. I knew there had to be one from parsing python all night, but hadn't found it in the images that were around.
Any chance there is an identifier on the potentiometer on that motor?
Nothing on it at all
Steve can you check yours, no identification on mine
I'm pretty sure the Piccolo (the big MCU in the middle) is doing a couple of things.
1. Reading the MPU-6000
2.Interfacing with the GoPro.
3. Managing the CAN-BUS (the vp232 is a CAN transceiver)
4. Chatting with at least the Piccolo on the uppermost PCB (the one with the hole for the yaw motor)
5. Fusing the potentiometer data with the relevant axes from the MPU-6000 (OR MAYBE NOT?)
6. Outputting PWM to hold/allow motion on the arm motor.
An impressive amount for an MCU, which I guess is why it's a 32 bit jobby.
