Hi! I've found a source code where the wheels of a rover are commanded with an Adafruit PCA9685 16-Channel Servo Driver. The library used is i2cpwm by Bradan Lane. Is it possible to use the same library connecting 2 DC motors to the L298 h-bridge? Or does anyone know to guide the rover with this hardware and ROS? Thanks a lot
Hello We had problems in controlling the 2 dc motor. You can find the solution in the our reporstory on Github. https://github.com/bekirbostanci/ROS_...
Could you please update your answer with a copy and paste of the solution? If your repository were to disappear, then your answer will become less than useful. Also, it's difficult to find the solution by searching in a repository with many directories and files.
Solution is not very short so that I published github link. I am developing this reporstory and ı will write a readme file how to use this repo. Re-share the file link below
You could use the pca9685 to Controller the enable Inputs and other io for select the a and b. Und Drive you Rover.
Or use one for MCP23017 for the io.
Other cheap solution is a something linke this http://s.click.aliexpress.com/e/EIOLVWva
as you rover has only 2 motors you could connect the pins to both pwm pins you do not use andy audio
it ist the bmc 12 and bmc13
see the positon from here https://pinout.xyz/pinout/pin33_gpio13#
It is not possible to use this library because the PCA9685 is an i2c to pwm chip.
If you like to drive with the full speed then you can use gpios of the pi. If you like to control the speed then you need at least a two channel pwm source. Something like the adafruit you said in you post.
Then you can use this library https://sourceforge.net/p/raspberry-g...
And generate pwm with the pi gpios
