![]() What’s the Same? What’s Different?īeing a member of the Propeller family, the P2 is multi-core it has eight 32-bit processors that run simultaneously. Thankfully, the features that I hoped for (and that are not part of the P1) are built into the P2. I deliberately waited for the P2 hardware to be locked and Spin 2 (its native HLL) to be available before I spent time with it. That said, the hardware is done now and is very exciting - exactly what we would expect from Parallax, a company that has always been user-focused and done things a bit differently.įor the record, I was not part of the committee I just spoke of. Designs by committees always take longer, and when the committee giving input and feedback is literally hundreds of passionate users, things slow down. ![]() ![]() It’s quite unusual for a microcontroller to be developed so publicly and for the manufacturer to incorporate user feedback and suggestions. Many will ask what took Parallax so long to finish the P2 - especially since the P1 was introduced way back in 2006. What I’m hoping to do in this article is give an easy preview and show you how some of the neat new features can be leveraged in your applications. Those who give it a try and experience true multi-core programming are going to have a lot of fun and be tremendously productive. People that know my history know that I’m biased (I once worked for Parallax I’ve written extensively about their products and 90% of my consulting work is for the Propeller 1), but still, I believe that I can objectively say that the Propeller 2 is a very cool device. ![]() The next time I looked at the clock it was past 10 AM the following morning! A few weeks ago, I started digging into the Propeller 2 (P2) and have found myself having more wildly-fun all-nighters! After dinner one evening, I opened the kit and started to experiment. Well, about six months later, I had a change of heart and decided to order the BASIC Stamp 1 starter kit. My cynical side thought it too good to be true, so I ignored it. Back then, they were introducing an SBC (single-board computer) called the BASIC Stamp. Dimensions: 2.0 x 3.0 x 0.36 in (5.0 x 7.6 x 0.84 cm) mounting hole centers separated by 2.75 x 1.75 in (59.85 x 44.My first encounter with Parallax was through an ad that appeared on the back of Nuts & Volts in late 1993.Power Requirements: 3.3 or 4 to 9 VDC, up to 500 mA.Pads for sigma-delta A/D circuitry (two resistors and two capacitors, both 0603) for using the Sigma-Delta A/D AppNote.External brownout reset may be installed by removing SMT jumper.64KB EEPROM (32K for P8X32A program, 32K for general-purpose use).Bus-powered USB coupled with 3.3V regulator for 500 mA.Open hardware reference design through our Altium and DipTrace PCB layout files (more export options may be possible).5 MHz crystal on board may be disabled by removing SMT jumper, allowing replacement with external through-hole crystal.Expansion header provides access to Vss, Vdd, 32 I/O pins.With USB power and a selection of QuickStart Project examples it's also the fastest way to get up and running. As a project board the QuickStart is fully expandable and provides unimpeded access to all I/O pins through an expansion header but includes some button inputs and LEDs to demonstrate programming. Developers may use our PCB layout files as their own to speed their project towards completion. As an open-source reference design the QuickStart board provides basic Propeller circuitry. ![]() The QuickStart is an evaluation board for the Propeller. The P8X32A QuickStart is a simple and accessible development platform for the P8X32A Propeller microcontroller. ![]()
