I am trying to get an xbox 360 (clone) to work with my pi3b+. I follwoed the instructions for installing and running the driver (xboxdrv) and initially it seemed to work but.. 1) The suggestion to blacklist xpad on boot caused sudo nano /etc/modprobe.d/blacklist.conf blacklist xpad makes the xbox un...

Wireless Xbox Controller

As of today I am the proud owner of an Xbox controller (wireless). Install went fine, the pi recognises the controller and all is well.
But..
Why do I need to SUDO xboxdrv ? How can I make it work without sudo ?
And where are the install files of xboxdrv ?

Many thanks

Re: Servo jitter and GPIO 29(??) SOLVED

Thank you everybody for your answers My problem was the extreme shaking caused on the camera mount caused by the engine when running. Small jitter appears to be an inherent problem with small (cheap?) servos and it appears that it is difficult to solve. I finally solved the violent shaking using a t...

Re: Servo jitter and GPIO 29(??)

Thank you pootle for your reply Will you please elaborate your answer? Did you use a servo board? I am NOT using such a thing getting the pulses directly from the pi with pigpio. What do you mean "decoupling caps right by the servos as well as on the driver board" ? Did uou remove them? It has been ...

Re: Servo jitter and GPIO 29(??)

Thank you rpdom and rpiMike for clearing the GPIO 29 issue. Joan, thanks for getting involved. I am using pigpio throughout my project which involves an engine and 3 servos.

Servo jitter and GPIO 29(??)

I am trying to detect what causes my two servos (MG90) jitter. Having tried a few solutions (that failed ) I used pigpio's PISCOPE just in case it provided with some more info. The image below shows activity at GPIO 29(??) which coincides with the jittering. I am not using and have nothing connected...

Weird pi happenings

I hope that this forum is the appropriate one.
I am using a pi 3B+
Weird thing 1:
While thepi is off, an LED connected to pin 2 or 3 is swiched ON!
Weird thing 2:
With the pi off, a connection to pin 2 or 3 switches the pi ON (it boots)!
Any idea why?
Is this normal?

Thank you all for your replies. The pi pins are 16 and 20. So how about this?
And how would it be if I wanted both lets to switch on together?

2 LED wiring

I need to connect 2 LEDs to a pi3b
Does the image below show the correct wiring or does each led need to connect to ground through a 330 resistor?

I have just realised that the Broadcom chip gets very hot (too hot to touch).

Re: Have I destroyed my pi / my ESC from low voltage?

Thank you pcmanbob for this very quick reply. I will do what you suggest but, just out of curiosity, could the card be corrupted and still run the module without problems? And why pyscope does not show pin activity? Some more info: I use pigpio throughout the module. Now, from command line I set a p...

Have I destroyed my pi / my ESC from low voltage?

Untill a couple of days ago my py 3B was running my robot car module perfectly using pigpio. It would even display the pin status on pyscope. I then suffered from poor (low) voltage supply to the pi and since then when running the module I get no response from the pins and ESC controller and pyscope...

Re: GPIO to PIGPIO "translation"

Thank you bensimmo for your answer.
The first bit of code using RPi.GPIO prints values according to light conditions (dark/light)
The second, using PIGPIO prints 1 and does not change to light intensity.
There are no errors on running the code

I am using a pi 3B with the 2018-06-27 version of Stretch. I am not 100% sure but I believe that the previous version (2018-04-18) did not present this problem. I also just noticed that there is a new version of stretch and at some point I will try it.
