Re: [SOLVED] Installing PyUSB 1.0.0rc1 on VM 0.6

Thanks kristoffer for updating the VM, this is the better option for me since I messed up my Eclipse setup as well and planned to clone my and Bitcraze's repos from scratch...

Looking forward to jumping into the CF project again...

[SOLVED] Installing PyUSB 1.0.0rc1 on VM 0.6

Hi guys, it has been about half a year since I fired up my VM the last time and there was huge progress at Bitcraze and Github! Really happy to see that! I found out that the CF Client runs on Python3 now which I can call using "python3 cfclient", but it always says CRITICAL:cfclient.cfclient:No pyu...

Re: [SOLVED] Selecting an ultrasonic sensor and interface

Alex, are you using the volage regulator that you mentioned, and if yes, where? It seems from the pictures that you didn't use it. And will the maxsonar sensor still work without the regulator? Ist schön deutsche hier zu sehen. Grüsse von einem deutschen in America! Hey, sorry for missing your post...

Re: CF 2.0 not restarting in firmware mode after flashing

It is working!! :D :lol: Connected pin 1 to GND to set the sensor's address to default 0x70 and initialized I2C1_DEV with 100 kHz. It works for RANGING_CYCLE_MS = 80 or 100, doesn't matter. I don't know what the reason was, actually. Tested with the same address in the beginning. To speak from my o...

Re: CF 2.0 not restarting in firmware mode after flashing

I followed your report step by step (except for grounding pin 1, I'm still using address 0x30), but no change. I double and triple checked the prototype board and also hooked the sensor up again from scratch without the board in between --> copter always shows the same symptoms i.e. freezing after f...

Re: CF 2.0 not restarting in firmware mode after flashing

Perfect, great job! Glad that my code works fine. Thanks for buying the sonar, even though I could have lent you mine! Where did you get it from? I'm going to play around with my equipment again tonight, check my prototype soldering and breakout board wiring. What's that software on your screenshot ...

Re: CF 2.0 not restarting in firmware mode after flashing

Yesterday, I did some more testing: Added function to change the I2C address of the sonar sensor. See my repo, branch "sonar-cf2" Successfully changed the sensor's address to 0x30. Verified the new address via sensor pin 2 by looking at the address announcement with an oscilloscope (pin 2 high for 4...

Re: CF 2.0 not restarting in firmware mode after flashing

Well to steps forward and one back :). I'm thinking there is still something wrong with the i2c buss then. If you flash the release software I guess everything is working as it should (to rule out cfclient issue)? Yes, with the original firmware everything's fine. Didn't even change the cfclient. I...

Re: CF 2.0 not restarting in firmware mode after flashing

I set the I2C1 bus (for EEPROM and sonar) to 100 kHz and the copter starts up normally. The LEDs are acting as the are supposed to and I get a stable connection. Pushed the changes to my repo. But: The telemetry data in the PC Client is still showing weird values (e.g. the ASL). Neither the data fie...
