Altitude hold in dev_20120225 only works well at temperatures above 20 degrees. In a room works well, but outside no. In my workshop I have 18 degrees. Sometimes I get this in the GUI: Thank you for pointing this. I suspected something wrong about the MS baro code, as I also had a baro alt issue ou...

Stalk

What do you mean "not working"? It's working in both cases. No, windows ALT and debug1 should be nearly the same. Quad is in this case almost unmanageable. Both are in the same place, so the ALT should be approximately the same. I can not speak English well, so I can better explain. Stanley

And where we can define EXT_MOTOR_RANGE?

I added an external pullups 2k2. WMP and BMA020 are supplied directly from 5V.
In v1.8p2: WMP and BMA020 work, errors are about 600 in 5 minutes.
In v1.9.: Both work debug2 = 0 for 5 minutes.
Good job, thank you very much.

Stalk

1) Now is the BMA020 5V.
2) New Pullups I add Tomorrow, I go to sleep.

Stalk

When I powered WMP and BMA020 of 5V, it is the same. V1.9 many errors, status led permanently lights, WMP not works. V1.8p2 errors steps by 6, status led no lights, alarm sometimes flash, WMP and BMA020 works.
Pullups are not so easy to connect to the finished shield.

Stalk

1) BMA020 is connected via a 4-pole connector to JP17.
2) 4.69V
3) 4.95V
Thank you for your efforts

Stalk

I have Arduino Pro Mini 5V. Accurate Wiring is on previous page (in pic named Wii03.ch). My DIY board have two connectors for I2C device: one powered from D12 over diode (as recommended in the early) a another powered 3.3V.

Stalk

1. Using your voltmeter, with the meter's ground probe on the BMA020 GND pin, what voltages do you measure at its UIN and UPullup pins? 3.29V That would indicate that you are using a 3.3V version Arduino CPU board. Is that correct? If possible, please post the URL to the exact Arduino CPU board you...

2. What switch position did you choose for your Seeeduino ATMEGA1280's 3.3_VCC_5V switch?

Sorry, here is right scheme of my plate:

Stalk

@Stalk, unsolder the SDA and SCL wires from the BMA020 board. In the V1.8p2 and V1.9 sketches, disable the BMA020, enable the internal pullups, and select 100KHz speed. Repeat your tests on both software versions. Are the error counts the same as before? Anything change? BMA020 unsoldered and disab...

Stalk

I suggest that both users install V1.8p2 with the I2C R/W test code patch discussed elsewhere in this forum. If there are no I2C errors with that test then we can be assured that the sensors and I2C buss are fine and that problem with V1.9 is only in the new code. If the V1.8p2 I2C chirp test fails...

Stalk

Nothing has changed, WMP does not work, BMA020 works.

Stalk

When I this uncommented, does not work.

Stalk

BMA020 is from ELV. recapitulation: WMP BMA020 Pull-ups(internal) version working enable disable disable 1.9 yes enable disable enable 1.9 yes enable enable enable 1.9 no enable enable disable 1.9 no enable enable enable dev201129 yes enable enable enable 1.8p2 yes ITG3205 enable disable all yes

Stalk

I found that when commenting BMA020, WMP will work and i2c_errors_count = 0
When he Uncomment i2c_errors_count WMP does not work and continuously increasing.
Apparently there is a collision WMP and BMA020 on the bus. What to do?

Stalk

I have Pull-ups For WMP enabled, for ITG disabled.

Stalk

I work at 100kHz with WMP

Stalk

In your new V1.9 release the debug2 window now shows the I2C error count. You haven't said if yours has any errors being reported. What number do you see?

The number is constantly and rapidly increasing with WMP. With ITG3200 is 0.

Stalk

Hi all,
In version 1.9 I have no response from WMP (original) in the GUI. BMA020 shows movement. With ITG3200 BMA020 the response from both.
In previous versions, everything was OK.
Thank you for your help.

Hi Alex,

Hi Heiko,
thank you for your help.
For 12A I use the hex file from this site?
Sorry, but I'm not a programmer and I can not assembler.
Good luck,

Hi,
I tried to fly with the ECC with the firmware from this forum. After about 8 flys one burnt ESC.
There was talk here about the removing three capacitors. What are they please? I have Mystery20A/HK Blue 20A and HK Blue 12A (see pictures).
Thank you in advance for your help.

Hi zis_dm,
Thanks for the advice. I will try it later. How do I remove cooler? It's probably glued?

Stalk

Hi,

I reprogrammed the ESC HK Blueseries four and three 20A Mystery 20A firmware from this topic. One piece Mystery 20A does not work with this firmware (see my posts above). When the ESC is still working normally with the original firmware.
Can you deal with someone?

Regards

Stalk

Hi ziss_dm,

I tried ESC HobbyKing BlueSeries 20A and ... functions. ESC HK has Atmega8A, while Mystery Atmega8.
I do not know the difference. I can not generate a hex for ATmega8A. Would you assist me please?
thank you

Hi ziss_dm,

Mystery20A_pwm_fast_200.hex this works just as wrong - just beeps and twitching. Just I drive through servotester.

Hi ziss_dm,
the original firmware. I thought that you want to verify the correct operation of my programmer.
Mystery20A_aerduino_pwm.hex not working for me.

Hi ziss_dm, I flash normal RC firmware back intu ESC and its work normally. However, when I flash fast firmware again, it does not work. Only four beeps and turn choppy when I turn on the motor. It would help remove the three capacitors, which you talked about earlier? I'm running on 3 lipo. thank y...

Unfortunately I'm at work. I will try it tonight. Should I remove the capacitors, which are discussed above?
I do not know but ktré are.
thank you

Hi ziss_dm Thank you for your reply. I tried MINTHROTTLE until 1250, but unsuccessfully. I also tried a bigger engine 20-22L, but nothing.

I reflashing alternative firmware to ESC Mystery 20A. I modified the MWC by ziss_dm. I have connected the engine Keda 20-50. The engine does not start. Only slowly rotate jerky.
How can I be wrong?
Thanks for any reply.

Stalk

In this way I program without soldering.

Stalk

Correction:
The motor will beep four times. They try to spin, but not spin. Only turning jerkily.
Where's my mistake, please?

Stalk

We figured it out. The Mega Seeduino it is:
Reset - 53
MOSI - 51
MISO - 50
SCK - 52
Everything went as it should

, but the ESC will beep three times and just enough. Arduino Pro Mini MWC him start.

What to do, please help.

Stalk

I use Mega Seeduino v1.22 as a programmer. ISP pins are 10,11,12,13 or 50,51,52,53? Here I could be wrong.
Thank you for your answer.

Hi everyone,
I have a similar problem (WMP + NK both original), but only in a stable mode.
With ITG3200 + BMA020 it is OK.

Stalk

Hi, I discovered there is an overflow variable error here: PTerm = errorAngle*P8[PIDLEVEL]/100 ; //680*10 = 6800: 16 bits is ok here For the moment, this should be changed to: PTerm = errorAngle*(P8[PIDLEVEL]/10)/10 ; //680*10 = 6800: 16 bits is ok here Something similar happens to me with version ...

Hi Your honor ziss_dm, this is spectacular!!!!! Already after the first flight, it is clear that it is much better. I do not understand too much calculation in the IMU, but it seems to me similar to dev0607. Still dev0607 did not work well with my ITG3200. Can I use your modified sketch with WMP or ...

Thank you for your help, I'll try your tips and I'll know. ITG3200 I was connected directly to the Arduino, now I have a 4k7 pull-ups to 3.3V and internal disabled. But it is the same.

This initialization code I use, but is very nervous tricopter compared to WPM.
Nevertheless, I thank you, you're the only one who tried to help me.

Stalk

My tricopter and quadrocopter fly very well with the WMP and BMA020 with software version 1_7.

But ITG3200 and BMA020 are turbulent, does not help tuning PID. I tried 1_7, dev0529 and dev0607.
I've spent with it for several weeks without result.

You advise someone what is wrong?
