Hi, its problem with dev version of multiwii (stable multiwii 2.1 work fine). At the moment I getting started to work on new sw version, whitch will support these changes in MW.

Good to know. Except now, PPM_ON_THROTTLE doesnt work. bah. I just can't win w/ this one.
Please MichalM, can I ask for support of the MWC POWERMETER? I would like to be able to read the current from the MWC verse connecting the current sensor to the mobiDrone.
1. I noticed a bad flickering, is there a known reason why the OSD is flickering randomly and is invisible sometimes for a few moments, which connection can be the reason.
2. I believe the artificial horizon is swapped How can this be corrected?

Is this video that has gone through a wireless transmission? (if yes, what setup) or is this direct feed to monitor from the mobidrone?
also, when flashing firmware onto this board... it is kind of dumb. you have to connect the tx/rx/gnd, then, once you push the "UPLOAD" button in Arduino, THEN you connect the 5v to it, and it will upload.
Hi, I am unable to connect to the osd chip, I tried to reflash the bootloader but nothing helped, I always get: avrdude: stk500_getsync(): not in sync: resp=0x00
Michal, can you help me out here?
Why should I connect the 5V at the moment the compiler is finished? Will 5V from FTDI be enough?

You should connect it the second it finishes compiling because he tells you to do so in the instructions. Seems he doesn't have a Arduino Bootloader on there which will throw the out of sync error if not connected correctly.
It sounds rather dumb, but once you get it figured out using the wire connectors like readerror said, it's rather simple.
gluck!
ps. now fix the arm function not working on 2.1+dev
The reason you have to connect the power to the OSD at certain moment is because the reset circuit present at normal arduino is not on this OSD. The timing is very important, since there is a short window where you can initiate the programming, if you miss it the OSD will just load the already loaded code. I usually keep an eye on the Tx LED on the FTDI, push 'upload' and after the first blink of the Tx LED I connect the Vcc pin. It may take few tries but it works most of the time just fine.
What deet says - almost always gnd - make sure use the camera one. It solved mine. If 5v is noisy try using a coil/cap putting a big cap accross 5v line to OSD. min 470uf. 3300uf usually does the trick!!
My RX is powered by the flyduino FC. So the 5V should be as noisy as before. The wire that connects the fc to the osd s very long. is it possible that the motors xause a magnetic flux?
Hi, I have 4,6V from the Serial Ports 5V pin 2Ohm between GND of RX and GND on serial port. I tried several things: Powering 5V from RX or ESC does not help
I tried to get GND from ESC but without the cam the OSD does not work.
Hello Can you help me? I tied Ultralight 50A Current Sensor (pin S) N1 entry, set sensor 3 and I have a problem. As I powered quad starts and counts 20-30mAh/sec and shows consumption of 25-30A engines find Not started. Do you know why? Thanks
Hi, gps data freezes when I use the osd.There seems to be a problem with multople serial ports in 2.1 on mega2560. would it be possible to send the data to osd via i2c?Maybe I can help programming it...
Hi guys. I have a problem with my bat 2 voltage sence. Im unning 4s and i have done the hardware and software mod to suit the 4s input. The problem is that the voltage display fluctuates. ie at a steady 16.5v input the display will fluctuate anywhere between 15.8 and 17.2v. Its not very acurate especially when im only oporating down to 15.2v. Any idea what the problem may be. Is their a sensitivity adjustment in the code? Its all grounded ok.

given the voltage divider is already on the board, not sure the zener diode solution can be applied, unless you have done so already. In which case what value zener did you use?
Ok, i inderstand the theory of the zener, but wouldnt i then have to change the divider R values on the board? Deet, i see that you run 4s input. Did you have the same issue? Im wondering if i have a faulty board. I'll try to measure the volts at pin 24 ot the ATMEGA328 chip and see if its steady.
ok with a input voltage of 16.52V at the batt input of the osd, im am getting a steady 4.133V at pin 24 of the ATMEGA328 chip. Therefor i know that the divider cct is oporating ok. But the osd Display is still fluctuationg aprox between 15.8 and 17V.

Thanks for your input guys.
If you use a 4.3V Zener inline, that should drop the voltage (4S to 3S) to a point where nothing else has to be changed

So are you saying to remove the extra 10k resister that i installed inline and revert the code change that michalM_sk said to do and instead install a 4.3V zener. Ok i will try.
MichalM_sk wrote: Hi,
there is needed two steps to 4S support:
1.HW modification it is possible change first 10kOhm resistor (from bat pin) to 20 kOhm or add one 10kOhm resistor.

No, what I am saying is to simply add the zener in series, in other words,
Ok i was just making sure that you know that i dont have a normal connection (as what is shipped) ive already added an extra 10k resistor as per michalM instructions for 4s.
So ill keep that 10k and add a zener. Will let you know how it goes. Thanks for your help.

Any ideas?
this is would indicate a fault on the board or in the code/processor itself
I have a problem when i press sensor calibration from mobiDroneOSD hangs in addition she throws trash in Aux and PID tuning. I have crius SE with MultiWii dev version r1240 (2012/10/31) and mobidrone with mobiDroneOSD_v2.3_PRE_RELEASE_7.8_REPACKED code . How can i remove this bug?
