Parallax 32150 Propeller Mini
The Parallax 32150 Propeller Mini is a compact, single-chip microcontroller featuring eight independent 32-bit processors running at 80 MHz, designed for embedded systems and robotics applications requiring parallel processing capabilities. Professional engineers, hobbyists, and educational institutions use this platform to develop multi-threaded applications where traditional single-core microcontrollers fall short in real-time performance. This device solves the complexity of coordinating multiple simultaneous tasks by offering true hardware parallelism, enabling developers to run servo control, sensor acquisition, and communication protocols concurrently without software overhead.
Product Overview
The Parallax 32150 Propeller Mini operates on a revolutionary multi-core architecture with eight Cog processors, each capable of executing independent program threads simultaneously. Unlike conventional microcontrollers that use interrupt-driven multitasking, the Propeller Mini's hardware parallelism allows each Cog to run at full 80 MHz clock speed without context switching overhead. This architecture eliminates race conditions and timing conflicts inherent in traditional RTOS implementations, making it exceptionally reliable for time-critical applications. The processor includes 32 KB of hub RAM shared across all Cogs, 32 KB of ROM containing the Propeller interpreter, and 64 KB of additional RAM for program storage and data manipulation.
The Propeller Mini integrates 32 I/O pins with configurable digital, analog, and PWM capabilities, enabling direct interfacing with sensors, motors, and communication modules without external logic level converters for 3.3V systems. The built-in phase-locked loop (PLL) and clock management circuits provide flexible clock generation options, while the integrated counter modules on each Cog support hardware-based pulse width modulation, frequency measurement, and quadrature encoding. This compact form factor maintains full compatibility with standard breadboards and development shields, making it ideal for rapid prototyping while delivering enterprise-grade parallel processing performance.

How to Use
Begin by connecting the Parallax 32150 Propeller Mini to your development environment using the Propeller Tool IDE, which includes the Spin language compiler and assembly language support. Install the USB driver for your operating system, then connect the development board via USB to enable programming and serial communication. Configure your clock settings in the Spin code using the Propeller's clock configuration registers, typically setting the PLL multiplier and divider to achieve your desired system clock frequency. Each Cog is programmed independently using Spin or Propeller Assembly, allowing you to define separate methods that execute in parallel without interference.
To implement a multi-threaded application, declare separate methods for each Cog's functionality and use the cognew() function to launch them on available Cogs. Utilize the mailbox mechanism in hub RAM for inter-Cog communication, implementing semaphore-based synchronization if multiple Cogs need to access shared data structures. Configure I/O pins using the dira and outa registers for digital output, or leverage the built-in counter modules for PWM generation and pulse measurement without dedicated software loops. Test your application using the serial terminal to monitor Cog execution and verify that each processor is running its assigned task independently and concurrently.
Frequently Asked Questions
What is the difference between the Propeller Mini and the full-size Propeller chip?
The Propeller Mini is a compact breakout board version of the Parallax P8X32A microcontroller, offering the same eight-Cog architecture and 80 MHz performance in a breadboard-friendly 40-pin DIP package. The full-size Propeller development boards typically include additional onboard components like USB programming interfaces, voltage regulators, and expansion connectors, while the Mini provides the core processor with minimal supporting circuitry for maximum flexibility in custom designs.
Can I run eight independent programs simultaneously on the eight Cogs?
Yes, the Propeller Mini's architecture allows each of the eight Cogs to execute completely independent code threads at the same time. Each Cog has its own 512-byte instruction RAM and executes at full 80 MHz clock speed without any time-sharing or context switching. You can launch different methods on different Cogs using the cognew() function, enabling true parallel execution of servo control, sensor reading, communication, and data processing tasks simultaneously without performance degradation.
What programming languages are supported for the Propeller Mini?
The Propeller Mini is primarily programmed using Spin, a high-level language specifically designed for parallel programming on the Propeller architecture. Spin code compiles to bytecode that runs on the Propeller's interpreter, making it easy to develop multi-threaded applications. For performance-critical sections, you can write Propeller Assembly language, which executes at full speed on individual Cogs. The Propeller Tool IDE includes both Spin and Assembly editors with integrated debugging and simulation capabilities.
How do I communicate between different Cogs running on the Propeller Mini?
Inter-Cog communication on the Propeller Mini is achieved through shared hub RAM, which all eight Cogs can access simultaneously. You can implement mailbox-style communication by designating specific hub RAM locations for passing data between Cogs. For synchronized access to shared resources, implement semaphore mechanisms using Propeller Assembly's lockset and lockclr instructions, which provide atomic operations for thread-safe data sharing. The Spin language provides high-level abstractions for common inter-Cog communication patterns.
What is the maximum number of PWM signals I can generate simultaneously?
The Propeller Mini can generate up to eight independent PWM signals simultaneously using the hardware counter modules built into each Cog. Each Cog's counter can be configured to generate PWM output on any of the 32 I/O pins, allowing you to control eight servo motors or speed-controlled devices at the same time without CPU overhead. This is a significant advantage over traditional microcontrollers that typically support only two or four PWM channels through dedicated hardware.
