SUMMARY

This discussion focuses on controlling motors for robotics and CNC machines using serial ports on Linux computers. The UART (Universal Asynchronous Receiver-Transmitter), specifically the 16550A, is identified as the standard for serial communication. Additionally, the EZ-USB microcontroller from Cypress Semiconductor is recommended for its fast USB connectivity and integrated 8051 microcontroller capabilities, allowing for streamlined design on a single chip.

PREREQUISITES
  • Understanding of UART (Universal Asynchronous Receiver-Transmitter) communication
  • Familiarity with Linux operating systems
  • Basic knowledge of microcontrollers, specifically the 8051 architecture
  • Experience with serial port programming and interfacing
NEXT STEPS
  • Study UART communication protocols and implementation
  • Explore the capabilities of the EZ-USB microcontroller from Cypress Semiconductor
  • Learn about serial port programming in Linux
  • Research robotics control systems and CNC machine interfacing techniques
USEFUL FOR

Robotics enthusiasts, CNC machine builders, Linux developers, and anyone interested in motor control through serial communication.

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.
