MultiWii

There is no LPF filter for pressure sensor , i bet he didn't cover sensor with foam thats why graph is going up and down .

Hi.
I can't find any info what are those four DBG1..4 boxes and what they mean. I got problem with my quad and value at DBG4 changes between -4 to 4 value. Any suggestion what's causing problem?

OK my copter was drifting too. If its windy day its drifting but when there is no wind it drifts too. You should try to calibrate ACC only once , then try to fly and check if it still drifting . If it goes for example to the left , land , disarm motors , give full throttle then you trimm quad with P...

If it fly with original soft , you dont have to flash a fresh one . I always flash new boards with fresh multiwii firmware because then i know what is set up , and i know what i turned on and what is not . And i am sure that everything is ok and i did not crash if something is wrong whit preflashed ...

Ok if u connect board with connected motors to PC but battery isnt connected they will beep because the ESC detects that there is too low power to start them properly . If u connect battery first then board to pc they shouldn't beep. And you must remember that if you uploaded new firmware to board y...

It's not waste of money. U just don't know how to set it up . I gave u link to newbies guide and there is everything written how to do it . So read it well ,if u cant understand that , then in my opinion quad's aren't for you man . Referring to your point 1 : if u have QUAD X the u connect front lef...

It looks like mine MWC Crius SE. You should have an FTDI adapter that you connect to the board and to PC . Then in Arduino Ide open multiwii 2.2 or 2.1 preset it for your board and load it . If you dont understand this better read about using arduino IDE to load multiwii , and read the FAQ at multiw...

Maybe you need to cross TX with RX in FTDI and try it if it work.

If you flashed new firmware to FC , blue LED blinks because you have to do acc and mag calibration. Then it stops blinking. At least on my board i have that blink always after clearing eeprom then flashing fresh MW 2.2.

Hi. Take off props from motors . Connect to board by ftdi and uncomment : //#define ESC_CALIB_CANNOT_FLY and send to board . When its flashed to board it calibrate all ESC at one time. Remember to take off props beacause it spin motor at full throttle. When u done this comment back it and send to bo...

I did calibration but it doesnt do anything , its ESC fault i changed to one from my quad and it work as supposed to.

Ok i think i have wierd ESC min throttle must be 900 and max must be 1850 , other setting starts motor immediately.

Ok i got another problem. I got ARM under switch and when i arm the board, motor starts instantly something like in quadcopter. So i want to make that when i arm board the motor wouldnt start until i give more throttle. I tried to change min command , min throttle, and max throttle and no effect. An...

Ok i need little help with my strange problem. I connected everything to arduino nano as its in PatrikE tutorial and when i power up everything ESC is constantly beeping. Cant start motor even when i arm board with switch i get only fast beeping . All stick work correctly moving ailerons ,elevator a...

Hi can somebody explain me what do those parameters marked in a red line ? I searched what are they for but couldn't find a good explanation of that.

Hi,
Im wondering can i connect to i2c pins on crius se directly to ublox i2c pins to get gps working ? Or its impossible to do that without adapter ?

I had same problem with my Crius SE. First chceck at GUI is all signals for PITCH,ROLL,YAW is at 1500.If they aren't try to trimm on your TX to 1500 values, and check again motor. Second Thing could be a too much vibrations from motors.

You must do that from arduino software not from multiwiiconf. Its same as you want to flash new multiwii firmware but u select eeprom_clear , send it to board, wait 30 sec then flash again multiwii 2.1 .

No reset button , he mean's a sketch from Arduino IDE, open FIle --> Examples -->EEprom-->eeprom_clear and flsh it . After that Flash fresh multiwii firmware and try to calibrate mag now.

You didn't say what version of multiwii you have? Is it a Crius lite or SE ,or maybe AIOP ?
