You could totally implement that in the python client and map a button on your controller to toggle modes if you're feeling adventurous I only implemented the transmitter side in the devo firmware, though. I did recently implement a "cppm passthrough" commander type that emulates a standard multi-channel transmitter, and I decided channel 5 to switching between rate/level mode. It's good for playing around with, but it's ultimately a bit of a pain. Yes, for the non-persistant acro mode, I'm changing the values from within the client. You still need to lug the computer around, but you'll get the better stick precision. You also have the option of flying tethered to a computer via USB - most transmitters (devo, FrSky Taranis, Spektrum) also support a mode where they'll enumerate as a USB controller, and you can configure the crazyflie python client to use those. The ceramic antenna will be a bit better, but not as good as the external dipole (and I even managed to fit the dipole wifi-style antenna inside my devo7e by taking the plastic cover off and getting creative. Make sure you get a NRF42L01PA+ (pa stands for power amp) radio with an external antenna - the PCB antennas are junk.
You're basically soldering the radio used on the crazyradioPA to the SPI pins inside the devo.
YAW PTERM BETAFLIGHT MOD
Tobias has a post on the mod - it's not a very hard modification. I personally wish I didn't waste my money on the 7e and just saved longer for the 10 (It's like $120 instead of $60).Įither way, to fly untethered, you do need a transmitter mod. I think the Devo 7e is fine for flying the crazyflie nano around in level mode, but you'll quickly outgrow it if you want to fly a larger quad due to range of the stock transmitter (if you're using spektrum or other external receivers) and precision of the sticks. I'm now on the Devo10 (the white one) and I strongly recommend it. I started out on the Devo7e, which does a good job for the price. I was shocked how much better I could fly when I first moved to a real Tx (the crazyflie was my intro to the hobby - had zero RC experience prior). Hey hittstick - yes, a transmitter with proper gimbals/sticks will make a huge improvement.
I definitely see the benefit to a controller where the thrust stick doesn't snap back to center. When I can I'll try to get some video uploaded to better illustrate this.įor the first method for non-persistant acro mode, are you changing those values from within the client? The flip happens when I try to perform an orbit and start speeding up, and also when I attempt to change direction quickly. Which Devo transmitter are you using, specifically, Did you need to implement a receiver as well or can it connect to the signal from the stock antenna?Īll of my flying has been indoors, so far. Looks like I have some more saving to do. Which reminds me: I need to write a wiki on that. If you're interested in flying acro I suggest checking out a devo Tx running deviation - I recently added a commander protocol that can transmit up to 14 channels and made one of them map to switching between acro and level, and added support for this in the deviation code. rpyt.c#L70) to change the default and rebuild This doesn't persist across a reboot.Ģ) You can modify the source crtp_commander_rpyt.c, line 70 and 71 (.
The copter will still be in level mode.ġ) There are parameters for the roll and pitch PID mode (RATE and ANGLE where rate = acro and angle = level). "advanced mode" in the python UI means the advanced features in the pane below are unlocked - things like the ability to increase max angle setpoints.
