DMX Sequenced Servos

Description: The project is inspired by the successful implementation of DMX sequencing with various Parallax products. The objective is to utilize the Propeller microcontroller to control not only lights but also motors, solenoids, servos, and other types of actuators. The analysis of Vixen, a free software tool, has been conducted to facilitate this endeavor.

The proposed circuit design leverages the capabilities of the Propeller microcontroller, which is known for its multitasking abilities and versatility in handling multiple inputs and outputs. The circuit can be structured to include a DMX512 interface, allowing for the transmission and reception of DMX signals. This interface will enable the Propeller to interpret DMX commands and convert them into control signals for various actuators.

To implement this, the circuit will consist of a DMX receiver module connected to the Propeller's GPIO pins. The receiver will decode the DMX signals, which will then be processed by the Propeller to control actuators such as DC motors, stepper motors, and servos. Each actuator can be assigned a unique DMX address, allowing for precise control over multiple devices from a single control source.

The output stage of the circuit will include driver circuits tailored to the specific types of actuators being controlled. For instance, H-bridge circuits can be utilized for DC motors to allow bidirectional control, while PWM (Pulse Width Modulation) signals can be used for servos to dictate their position accurately. Solenoids can be controlled through relay modules that switch the power supply on and off as needed.

In addition, the circuit should incorporate adequate power supply management to ensure that the actuators receive sufficient voltage and current without compromising the stability of the Propeller microcontroller. Proper decoupling capacitors and voltage regulators may be employed to maintain a clean power supply.

Furthermore, safety features such as current sensing and thermal protection can be integrated into the design to prevent damage to the actuators and the microcontroller. Overall, this circuit aims to provide a robust solution for controlling a variety of actuators using DMX sequencing, expanding the applications of DMX technology beyond traditional lighting control.I was inspired by the excellent work done by others on these boards using DMX sequencing and various parallax products to interface with them. I decided to take my crack at it using the propeller only with a slightly different spin, pun intended.

I decided rather than control lights, why can`t I control motors, solenoids, servos, or other kinds of actuators? I spent some time analyzing a free software called vixen which others have pointed out as a great tool.

Since all I need are the..
