For some reason I found myself reading these newsgroups which I haven't really used for many years. It seems that although the Parallax Propeller web forums are extremely active there never seems to be much discussion elsewhere. Aren't you all curious as to what you are missing out on? I have used just about every kind of micro and architecture over the decades and while I might still...

I haven't heard anyone talking about the Propeller since earlier in the year when it had just been released so I'd like to share my impression of it with anyone who is interested. BTW, I have been heavily into LPC21xx ARM chips the last year or so and this is something completely different. I received a Parallax Propeller eval board last week and I have been hooked on it since. At the...

Over time most embedded design people reach familiarity with a controller and mostly C language. And with time we do get better performance and more functionality from the silicon suppliers. I work mostly with the LPC (ARM7) family and I am happy with it. I spend 3 hours reading a short article and looking at the tools of the new Propeller Chip. Parallax designed a simple 32 bit CPU and li...

Still can't believe it... It has 8 custom processor. One can generate color video while the other 7 each do a task. Slight modification allows the video to be broadcast. Can this thing be for real? No word on price or relase date. http://www.parallax.com/propeller/ What can you do with eight 32-bit processors (COGs) in one chip? Real simultaneous multi-processing! The new Propeller c...


Translating Parallax Pic assembly to Microchip

I have a number of older PIC projects that were written using Parallax assembly mnemonics for the 16C56 and 16C57, and I need to firstly convert the source code to Microchip mnemonics, and then make the programs run on newer PIC's with flash memory instead of OTP. I've spent quite a bit of time googling to try to find a program to do (or help me do) the source code translation, without much...

OK, the subject isn't quite accurate. I've been hacking around with Parallax Javelin processors and Basic stamps for a few years, and I used a pair of Javelins to automate a home theater. The problem is the implemtation was 1) a hack and 2) not entirely stable. Unstable home theaters are annoying. So I'd like to do it over, but I've got large areas of ignorance and concerns, and I'm lookin...

Hello, I had a few real basic question about microcontrollers. I've been learning the motorola HC12 at school, but whenever I pick up magazines or any kind of hobby related embedded type of reading material, the microcontrollers I see most often mentioned are the PIC and the STAMP and now something by Parallax called the Propeller chip. Here's what I'm wondering: Are the HCS12 more powerf...

Hello, I wonder if anyone makes something like Parallax did with PIC, but populated with ARM ? Anyone selling DIP40 device with ARM and FPGA and ethernet? With bootloader, RTOS and interpreter for fast prototyping? Digi has Connect ME device, but it is not DIP and anly 5 I/Os and UART from the ARM device is accessible. Lantronix has Xport with 3 I/O and UART and they are releasing new...


UART design considerations

I've implemented a simple software-based UART on a 50-mhz Parallax uC. I'm operating it at a baud rate of 2mbps. It talks to an FTDI FT232BM chip (http://www.ftdichip.com/Products/FT232BM.htm) in a usb- serial converter. While I've done extensive testing of the transmit portion of my code, I'm still working on and refining my RX code. Most UART implementations use an over-sampling (I've ...


Servo resets demo board

I attempted to piece together a system composed of a sensor, continuous rotation servo from Parallax and a Dragon12 plus hcs12 demo board in order to test a control algorithm. The problem is that sometimes when the program gets to a point where the servo control signal changes, the whole board resets. The servo runs on its own regulator so I don't think its a power issue. Why does running the s...

Hi. I'm teaching an intro class to embedded processor applications. The first part of the class used the Parallax Basic stamp, which is based on the PIC. I'm planning on using one of the Atmel ATMega's (8535, 16, or 32. What I'm looking for is any intro to AVR books that cover the ATMega line. I'm going to have the students use a processor in a breadboard, no pre-made boards, so I'm only look...
