Re: GPS integration

Hi,

About improving cpu time, it should be a better idea to just read one char or some char from serial line by loop
So after some loop the GPS string will be complete and one more loop later we decode it.
By this way , there is some gain improving the loop() for RC and sensors

Re: GPS integration

@patrike You can use my previous post , it should work, i get data from my GPS, but it is hard to debug with this board. Don't forgot to comment the part about INT on PORTD in newsoftserial. I report this part in RX.pde to handle interrupt and forward it to NEwSoftSerial class. @alexinparis, if you ...

Re: GPS integration

Just for information if you did not use SERIAL_SUM_PPM receiver, you have to comment out in NewSoftSerial the PCINT2_vect, because it is already used in multiwii for standard receiver interrupt and there is no more free port on portD i want to use the other motor pin which are free for my tricopter ...

Re: GPS integration

Hi,

The NewSoftSerial libray works with interrupt, buffer and allow highest communication baud, better than old softserial.

Re: New stable mode idea

Ok i will do a reflash with real 1.8, not SVN :) i think i miss a comit 2 days ago

I want autolevel too, to try FPV with remzibi OSD, i look at remzibi dev for arducopter and discover that sending correct serial data can display attitude :) so why not
But it is another thing to do once evrything is ok

Ok so, i can continue to look at part of code from ardupirat, which took pid loop for lat / lon, and maybe heading can be read from gps too when copter is in move.

Code is there just need to extract part for NMEA serial, reading / pid loop

Re: PDF controller for level mode

En lieu et place du code deja present, cette portion de code existe deja et elle commence comme pour l exemple par :

//**** PITCH & ROLL & YAW PID ****

et se termine aussi par :

lastGyro[axis] = gyroData[axis];

axisPID[axis] = PTerm + ITerm - DTerm;

Re: MultiWii program seem to freeze

Ok the capacitor was a really bad idea :)

But like ziss_dm says and as Hamburger confirm. I took the power from one of the three ESC and connected it directly to servo power.

Now all looks good :)

Tomorrow i ll do more test outside.

Thanks again

Yes it still look strange.

Just moving quickly radio rudder can hang the atmega.

If it is a power issue, why atmega does not reset and restart normally ?
