Hi there, i just switched from aeroquad to multiwii. I have several different boards & sensors available. I started up with a Seeduino mega + Razor 6DOF (analog) which seems to work (although i'm not sure if i get too many vibrations to the gyros).
I also have a mongoose 9DOF board which i would like to run with a promini. The mongoose seems already to be supported. But with the MWC Firmware flashed onto the Atmel on the mongoose board. I would like to have more io pins available (and i didn't have a ppm sum receiver) so i would like to use a promini as Controller and just the i2c sensors on the mongoose as external sensors. Im not very familiar with i2c - is it possible to communicyte with the sensors directly or does it interfere with the AVR chip on the mongoose?
If it works, How do i have to setup the sensors? Include each sensor manually in the config.h instead of using the mongoose directive?
Thanks & best regards,
Ben
Promini + Mongoose as sensorboard only possible?
Re: Promini + Mongoose as sensorboard only possible?
ok i just checked my Pro Mini it seems to be a 5V/16MHZ. Instead of using different level shifters i just ordered a ppm receiver.
But i came across one thing in the mongoose implementation where i'm not sure why it can't be solved in an other way:
The PD2 pin is used as the interrupt pin for the PPM signal. (This pin is not on the breakout board and hast to be soldered manually)
PD3 is still unused and available on the breakout board. Is there any problem why not tu use PD3 (interuppt 1 instead of interrupt 0) for the PPM Input?
