Controlling six 17-segment digits using three I/O pins

Wardy posted this article:  Controlling six 17-segment digits using three I/O pins Decided to start making good use of my “Propeller Professional Development Board” (PPDB) which has been sitting sadly idle and forlorn on the bench for a while. Set a goal of making a simple video game with some of the advanced features available […]

Parallax Emic 2 text-to-speech module

Parallax has released their Emic 2 Text-to-Speech Module. The Emic 2 is a multi-language voice synthesizer that converts a stream of digital text into natural sounding speech. The module requires a 5 volt DC power supply at 30 mA, and interfaces with your project via 9600 baud asynchronous serial (TTL). The module is capable of […]

Known as, it’s the online home for materials relating to the Parallax Board of Education microcontroller development systems and robotics kits for BASIC Stamp, Propeller, and Arduino. The site is in the development stage, and is being populated with links to tutorials for […]

Parallax Propeller retro pocket mini computer

Jeff Ledger wrote informing us of a retro-style computer based on the Parallax Propeller described in this Instructable. It utilizes the Pocket Mini Computer Kit from GadgetGangster. This board is based on the Propeller chip and includes VGA, audio and PS/2 keyboard ports as well as a microSD card slot and Wii controller port. The […]

Draft: Propeller 2 code authentication and protection

Parallax is in the process of designing its next gen Propeller chip. Informally dubbed the Propeller 2, the design includes a 32-bit, general purpose multi-core microcontroller with 8 identical cogs, a 160 MHz planned maximum clock speed, core voltage 1.8 VDC with I/O pin voltage of 1.8 VDC–3.3 VDC, 92 I/O pins total with each […]

Parallax Propeller encryption objects

Parallax has recently added two new encryption objects to their Propeller Object Exchange. Mark Tillotson has released his AES object. He describes it as an “efficient implementation of the Advanced Encryption Standard in PASM. Supports 128, 192 and 256 bit keys, ECB and CBC modes. All heavy lifting in PASM.” Mark also recently released his […]

Parallax KickStart tutorials

Anticipating an increase in interest in their products now carried at Radio Shack and other retailers, Parallax has posted a number of useful tutorials on their Getting Started with Parallax Wiki Google code site. Designed to bring beginners up to speed with coding and interfacing peripherals with the Propeller multi-core MCU, the Basic Stamp module […]

Parallax introduces laser range finder

Parallax has introduced the Laser Range Finder. “Designed in conjunction with Grand Idea Studio, the Parallax Laser Range Finder (LRF) Module is a distance-measuring instrument that uses laser technology to calculate the distance to a targeted object. The design uses a Propeller processor, CMOS camera, and laser diode to create a low-cost laser range finder. […]

Parallax introduces Eddie robotics platform

Parallax is introducing a new robotics platform based on the Propeller microcontroller. Known as Eddie, which stands for Expandable Development Discs for Innovation and Experimentation, the platform consists of dual 18 inch round bases positioned one above the other. The upper is designed with mounts for a Kinect and a laptop (used for what Parallax […]

Gear: Parallax Propeller emulator/debugger

While it’s been around for a while, few users of the Parallax Propeller are aware of of the debugger known as Gear. Gear is an open source Propeller emulator, with support for step through debugging and component plug-ins. It runs under Windows XP and requires .NET 2.0. It does not appear as full featured as […]

Joe Grand’s laser range finder

Joe Grand has finished work on his Laser Range Finder (LRF) project. This project, which has been in development in cooperation with Parallax Inc., is now in final beta testing. Check out Joe’s development diary for all the exhaustive details and links to development videos. Joe reports that after final tweaking is completed, he expects […]

Parallax GPS + Arduino

Here’s a good video from Kevin Darrah for those new to GPS basics demonstrating how to interface the Parallax GPS module with the Arduino. Note that while this video is based on the discontinued PMB-248 module, Parallax indicates that their current PMB-688 module is pin compatible (as far as TTL interfacing is concerned) and will […]

Propeller software USB host

Beth from scanlime has posted this code for creating a USB host in software on the Parallax Propeller. Beth got interested in this concept while considering whether USB WiFi and Bluetooth modules could be interfaced to the Propeller. She wanted to see if a USB host controller could be implemented entirely in software on the […]

S/PDIF Digital Audio on the Parallax Propeller

Beth from scanlime has posted a detailed explanation of her development of an S/PDIF encoder object for the Parallax Propeller. The source code is open under an MIT-style license. If you’re a Propeller enthusiast it should be easy to implement this code to give your next sound project a digital output. Beth hopes that this […]

Parallax releases Propeller C3 board

Parallax has released their Propeller C3 application board. Features include: Multicore Propeller P8X32A-Q44 with 5.00 MHz socketed crystal to upgrade for over-clocking experiments, 64 KB Propeller boot EEPROM holds boot image plus 32 KB extra for data, USB or external power sources, dual high-current filtered 1.5 A 3.3/5 V voltage regulators, VGA port, RCA Video/Audio […]

Parallax Optical Finger Navigation module
