Error Opening V4L Interface: No suck file or directory

Hi,

Im having an issue getting the mjpgstreamer working. When I run ./startrobot I get the following. Any suggestion as to what the issues is? I have the Raspberry PI Camera and have tested that it works with raspistill.

pi@raspberrypi ~/robot $ sudo ./startrobot

4 wheel math?

Has anyone done the code/math for 4 wheels? Having the joystick interface on https://github.com/shaunuk/picar would be better.

L298N Motor Controller and PWM

Hi,

I received my motor controller and platform but Im having issues getting the motors to work and I believe its an issue with my PWM configuration and cabling. I have a Sainsmart L298N H-Bridge and unfortunately it came with no instructions and I cant find a lot of good examples on the net.

My question is how you have the your L298N cabled for PWM, Do you have ENA and ENB jumpers removed and then both of these connected to GPIO pins and if so which pins and what configuration do you have for them?

Regards,

Kassal
