it seems that it suffers from exactly the same flaws as stock Multiwii - unnecessarily sluggish response to stick input in althold mode. I say that because the D-term completely ignores the stick input. Or have I missed some sneaky coding? Vario-based altitude hold [censored] is not implemented in ...

how to submit a patch to add a board.

this only require sensors orientation , you are using an 328p and did not add new sensors ?

post a patch here or create a pull request on github for reviewing , https://github.com/multiwii/multiwii-firmware .

best regards,

treym

fix :

Code: Select all

case MSP_EEPROM_WRITE:
        if (f.ARMED) {
            headSerialError(0);
        } else {
            writeEEPROM(0, true);
            headSerialReply(0);
        }

this way , you can still adjust pid while flying , just trigger the save when landed .

How difficult is it to get a standard Arduino Leonardo+IMU running MultiWii?

as hard as set MCUType=atmega32u4 , just refere to http://code.google.com/p/multiwii/source/browse/

with Arduino 1.0.1 so you just need to select the Leonardo to use it. It is fully supported by the MultiWii software since the 2.1 or later

Is there a way to have different “rates” selectable via tx-switch? (or inflight adjustable via proportional channel)?

yes, there is this code .. you can have more info here

This proposal allow a mild version of expo/rate for precision then another set for acro or more aggressive maneuvers.

It must be noted that you can find working implmentation for this serial communication written in C , C++ , .Net , java , javascript .. and probably some more languages ..

so , any news ? how did you handle the channel sync ? what about the replay and the implied delay when you switch from rx to tx ( is it full duplex ) ?

What feature are you looking for ?

- folow terrain contour (mostly like althold but using ground as reference)

- auto takeoff/landing

the sonar is not used .. yet .. but you can add it into the code if required

be sure that your 5vot bec can supply enough current for everything .. servo included.

be sure that everything use the same ground reference , ie : notably 5v bec and esc ground and servo ground sould be connected together .

mag calibration has nothing to do with your issue .

the request for MSP_ATTITUE is a zero lenght payload wich is implmented like this :

treym

it is both

with a generic customMSP one can use the payload to create additionnal mesages , and paved the way toward the ability to change any baseflight (or multiwii fork) variables.

the only requirement is to have a reserved msp for this purpose , ie #define MSP_CUSTOM 1
