No real time data in Multiwiiconfig after flashing with 2.0

[Wiidewd]

Hi, new to this BBS (forum) so greetz to all.

I have a multiwii board a friend brought back for me from China. The make is unknown sorry, it does have a cool feature, built in USB, otherwise seems fairly standard.

I fired up mutliwii config, selected COM3 and clicked start, real time data was working and all seemed well. I then flashed the board with 2.0. The first thing I noticed was the LED marked D4 came on and stayed on. I then went back in to config and selected COM3 and hit start. I noted the mode had successfully changed to X but alas no real time data anymore. While in real time mode an LED marked D3 blinks rapidly (LED D4 is also still solid at this point). Unfortunately I did not take note of whether this happened or not before the flash when all was well.

Anyone have any ideas?

Here is a screen cap in case its of any use.

Thanks again.

What version was on it that worked?

When you move the Tx sticks does the GUI show their movement?

I see that I2C errors are being reported. The I2C error register should be zero but your screenshot shows over 30K errors. Perhaps you don't have the correct sensors configured?

Thanks Thomas, I just noted that (30k+ errors, cant be good)

The first time I used wiiconfig it was version 2.0. I tried to flash 1.9 and also 1.7 but had errors on compiling (I believe I may need to use older versions of the Arduino sketcher to do this?)

I had not yet connected an RX, i shall do this today and report my findings.

Thanks again for taking the time to reply.

The version of wiiconfig you use must match the MWC version loaded on the board. So do you know what version was loaded on the board by the supplier? I realize the original code is erased, but this information will help determine what may be wrong.

Regarding your V2 upgrade, are you sure that you have selected the correct sensors (with the correct I2C addresses) in the config file? Hopefully you board is one that is already defined in the config file.

Stick inputs are working correctly. Roll, pitch, Yaw and throttle all seem to function fine.

Unfortunately I have little information. It did have a slip of paper with it.

Notable content:
atmega328P
ITG3205 Triple axis-gyro
DMA180 Accelermoeter
BMP085 Barometer
HMC5883L Magnetometer
MWC equivalent to Arduino Pro Mini
FFIMU 0.35 9DOF IMU
FTDI USB integrated

of Any help?

Unfortunately that does not help ID the MWC version they had used on the board. To install the V2 upgrade I suggest you start by using the config defines to enable only the gyro (with all other sensors disabled). If it is working error free then move to the ACC, then the Mag, and finally the Baro. Enable them one at time and check the GUI to verify they are OK before proceeding to the next sensor.

Thomas, thank you for pointing me in the right direction.

I enabled the following line of code in config.h

Code: Select all

#define FREEIMUv035_BMP // FreeIMU v0.3.5_BMP

It now appears to be working correctly!

Next step, test it on my known working setup (currently using a KK)

Again, appreciate your help

That is fantastic.
