Porting Multiwii to Arduino DUE - Done

[MHefny]

Hi,

I worked during the last three weeks on adding Arduino_DUE to Multiwii v2.3.
The end result is a code that can be compiled on ordinary 8-bit Arduino as well as Arduino DUE.

Awesome Job, I recently ordered a DUE for testing.

I use these mega shields available on eBay, maybe you can used one for this project.

[copterrichie]

DUE for 23.75.

Great work! I have barely touched my Due since I got it at release, the flash is starting to get rusty .
Tried it quickly yesterday before going to bed and noticed that the MPU6050 gyro values did not return to 0 when I tilted the sensor.
I was too tired to debug it yesterday, will try to see what it could be today if I find any spare time. Do you have any idea what it could be?

[MHefny]

I recompiled the code again to make sure there is no versioning issue in the uploaded one, and it worked as expected.
I found that the HK_MultiWii_328P is enabled in config.h by default so I commented it.

I think it is that the MPU6050 got both a ACC and GYRO on the same address that messes things up. When using both the acc and the gyro the values seem to get mixed, the gyro values acts more like a accelerometer and the acc values returns to 0 like gyro values.
When I disable the ACC in def.h the gyro values are working as they should.

I'm the proud creator of the worst explanation in the history of MultiWii.
Maybe this will make it clearer

Question for you please, considering the DUE is a large board anyway, would it be of any benefit using an add-on i2c eeprom device verse the eeprom emulator?

Example: AT24C256 Serial EEPROM Module I2C EEPROM Data Storage Module Arduino PIC

Sure this is possible. I think using DUE memory is one things that makes this porting useful and straight forward. Same idea implemented in Naze32. Yes sure you can do that but what is the benefit you will get over internal memory giving the current data you need to save for multiwii.

Please correct me here if I am wrong but is there a limited number of times the flash memory can be written to?

Thank you.

We're talking into tens of thousands of rewrite cycles, not something to really give a shit about.

depends on WHAT flash:
- MLC
- SLC

the later is ok - MLC can be as low as 800 read/write cycles.
depends what you pay for

chinese stuff is prob. write only ...

I was referring to internal flash on -modern MCUs.

Can you confirm the status of the I2C GPS functions working on the Due? I'm working on a project that leverages portions of the Multiwii code base. We have all of our code working on the Due, except for the I2C functions which communicate with the I2C GPS Nav board. We have incorporated the portions of your code that are pertinent to these operations. We can get a successful detection of the I2C GPS NAV module, but cannot successfully retreive data from the registers.

Thanks for your great work on this project!

[timecop]

Why the FUCK would you care about I2C GPS on a board with like 5 serial ports?

Pls chk my I2C updates in sensors.cpp i kept the function signature i changed the code.
But i never tried gps

Ciao MHefny
Scusa se ti scrivo in italiano.
Ho visto il tuo lavoro su arduino due e sono rimasto colpito complimenti.
cosi mi sono attrezzato o aggiunto External I2C EEPROM to Arduino (24LC256)
http://www.instructables.com/id/Adding- ... duino-Due/
Ma al momento non comunica con la MultiWiiWin GUI
vedi filmino, poi ce la SPEKTRUM sat che al momento della compilazione fa un errore

Dai MHefny che ce la facciamo se mi dai una mano.
In caso fai delle modiche al software, inserisci un file zip. nel forum.

Ciao, scrat

Molto molto bene complimenti a Tinnakon Kheowree

Ho appena provato il programma ma non abbiamo gli stessi sensori fa in piccolo errore, vedi filmino
lui utilizza MPU6050C, ed io FreeIMU_v0_3_5_MS mi domandavo se e possibile
integrare la FreeIMU_v0_3_5_MS e la spektrum satellit che funziona a 3.3V nel programma
cosi da evitare il bec da 5V. a me piacciono le cose semplici meno cose ci sono e meno problemi ci sono.

Vedi foto la nuova configurazione e molto più semplice senza EEprom e con solo spektrum satellit.

Hello, scrat

Very very good compliments to Tinnakon Kheowree

I just tried the program but does not have the same sensors in little error, see home movie
he uses MPU6050C, and I FreeIMU_v0_3_5_MS I was wondering if it is possible to
integrate FreeIMU_v0_3_5_MS and spektrum satellit that runs at 3.3V in the program
so as to avoid the bec from 5V. I like things simple, there are fewer things and fewer problems there are.

See photo the new configuration and much easier without EEprom and with only spektrum satellit.

Sorry for taking so so long to answer .
i suspended the work on multiwii DUE since a while, it was a POC. that it is doable.
