Firmware and example PCB for MSP430G2553 based Pick and Place machine.

Using a STM32L476 MCU to control stepper motor speed, direction, and step type.

The system uses a reflectivity sensor to sort 4 different types of objects into categories: black plastic, white plastic, steel, and aluminum.

Axis control with Atmel ATmega328 and saved positions in 24LC256 EEPROM.

This library enables you to use Hardware-based PWM channels on Generic boards to use PWM to control continuous Stepper Motor. The most important feature is they're purely hardware-based PWM channels, supporting very high PWM frequencies. Therefore, their executions are not blocked by bad-behaving functions or tasks

Controller board to use two steppers via DRV8825 drivers and provide accelerated / decelerated movement, constant speed mode, etc. via an I2C command channel

This library enables you to use Hardware Timers on RP2040-based RP2040 board to create and output PWM to pins. These PWM channels, using RP2040 Hardware-PWM channels, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software ISR-based PWM, using mil…

A MSP-EXP430G2 LaunchPad firmware to control the BOOST-DRV8711 Stepper Motor BoosterPack through a simplified UART protocol.

This is a prototype 8-legged spider with 2 pincers, 2 cameras for eyes, moving vision, and a mandible with pointy teeth to scare the little children, all made mode LEGO Technic. The MCU is an ESP32 Dev module, and software is written in C++.

This library enables you to use Hardware Timers on nRF52840-based Nano_33_BLE or Nano_33_BLE_Sense board to create and output PWM to pins. These PWM channels, using nRF52840 Hardware Timers, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software …

This library enables you to use Hardware Timers on an STM32H7-based Portenta_H7 board to create and output PWM to pins. These PWM channels, using Portenta_H7 Hardware Timers, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software or ISR-based PWM…

This wrapper library enables you to use Hardware-based PWM on STM32F/L/H/G/WB/MP1 boards to create and output PWM to pins. The most important feature is they're purely hardware-based PWM channels. Therefore, their executions are very precise and not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mi…

Unix-like operating system for CNC / Machine Control applications

A simple arduino CNC plotter which uses GRLB with H-bridge for driving Stepper motors. Uses DC motor for pen control mechanism.
