Learn Robotics & CNC Control with Serial Ports

[Shawnzyoo]

I am interested in learning how to control various motors
via my linux computer for robotics projects and possible cnc machines
it seems that serial ports are the most prevalently used for basic robot control
does anyone have any suggestions on where to start?
thanks

Study the UART (universal asynchronous receiver-transmitter) used in PCs for serial port communication, typically compatible with the 16550A. You should be able to build a device around another such UART, thus one UART on each end of the serial communications channel.

You may also want to consider using an EZ-USB microcontroller from Cypress Semiconductor. It not only provides fast USB connectivity (with drivers for your PC), it's also a complete, enhanced 8051 microcontroller, meaning you might be able to complete your entire design on a single chip.

Hi there,

That's great to hear that you are interested in learning about controlling motors for robotics projects and CNC machines using your Linux computer. Serial ports are indeed commonly used for basic robot control, and it's a great place to start.

One suggestion for getting started is to research and familiarize yourself with the basics of serial communication and the protocols used for controlling motors. There are many online resources and tutorials available that can help you understand the fundamentals.

Additionally, you may want to look into specific software or programming languages that can be used for serial communication and motor control on Linux. Some popular options include Python, Arduino, and ROS (Robot Operating System).

It may also be helpful to join online communities or forums dedicated to robotics and CNC control, where you can ask for advice and guidance from experienced individuals in the field.

Overall, the key is to start with the basics and gradually build your knowledge and skills as you progress. With determination and practice, you will be well on your way to controlling motors for your robotics and CNC projects. Best of luck!
