Almost free keyboard for portable prop?
Micro DataPad Mini Keyboard for Palm PDA m100/m105 Series $0.39
If it wasn’t for shipping, these are almost free keyboards for a portable prop project…
IIRC, the m100 is a serial interface.. I’ll let you guys know how I make out with these..
UPS shipping is the same for 1-8 of these..

ok here is what I an doing. I assembled a portable PROP unit it has a miniPS2 keyboard built into the top of a simple case and an LCD from a portable DVD player (it accepts NTSC) it has speakers and an NES port, and an SD card. all of this is conifigured to Jeff Ledgers PROTO-board cookbook wich i will upload so you dont have to track it down. with this little setup I have convinced my collage to start a TECH-CLUB based around the PROP and some gear i put together. this SD card has just the right combo of show ...This archive contains the official new release of AiGeneric Video Text V2.1. This zip is divided into two files: Version 2.1cf (which supports loading of Commodore fonts .64c files) Version 2.1 (which supports the original AiGeneric font system; replace old font files.) Both support the following commands: .redefine - Redefine characters on the fly .center - Center the line of text .putchar - Exact placement of characters .getchar - Exact retrieval of characters .color - 16 text colors amp support of most tv_text commands The AiGeneric_Video_DEMO in demonstrates all commands. Thanks to the collaborative efforts of Doug, Hippy, and Baggers this is truly a remarkable driver! Ok, I'm sick of editing this one for ...Wanted to share some thoughts about a new Propeller board project I've just started... Want to combine Propeller, for easy programming, SSD1963 for VGA graphics, and VNC2 for USB interface. Going to attempt to use FT232RL (or maybe FT231X) to program both Prop and VNC2. Also, going to try using 2X SQI chips on the 8-bit data bus of the SSD1963 to allow direct transfer between the two. If it works, should have GUI speeds and resolution that resemble earlier versions of Windows or Unix... Here's how the Prop Pins might be used: P0..P13 SSD1963 and SQI P14..P17 micro SD P18..P21 SPI connection to VNC2 P22..P23 PS/2 mouse P24..P25 PS/2 ...I have a robot that I would like to be able to plug into a computer's USB port, so the robot could type on the computer. I don't want to interface the keyboard with the Prop, just Prop to PC with no keyboards. I thought I saw a board on Sparkfun that allowed a microcontroller to act as a USB HID/Keyboard and I looked this morning and cannot find it. I also thought I read a post on this forum from someone who was also doing this with minimal hardware and pulled it off, but I cannot find that either. Thank you ...Will the Propeller fail to be detected if the eeprom is bad/missing? I just wired up a board to use the Propeller chip that I got in the "Mystery Bag". I had checked all the voltages and checked for shorts and everything looked good. I then plugged in the Prop and the eeprom but somehow when doing that one of the LM317 resistors broke and both chips saw 6+ volts. I fixed the problem and replaced the Propeller but I don't have another eeprom. The Propeller Tool still doesn't detect a Prop. I just need to know if the eeprom ...I had not been paying close attention to the Forums for awhile and missed the passing of the GG Propeller Platform. I sold the last two through hole PP kits that I had made up last week and was encouraged that I was able to come up with 8 PCBs for eight more kits, which are now available. The price is $38 plus shipping or $52 plus shipping with a Prop Plug. The kit comes with beefed up regulators with heat sinks, 5 and 6.25 MHz crystals, 2 24LC512 EEPROMs. I also have a test run for an updated PP pcb ...The Propeller DNA is fully backward compatible with the Propeller Platform USB. Propeller DNA - $49.99 Propeller DNA (w/RTC) - $69.99 Please see the WIKI for complete information on the Propeller DNAOk, beta testers... I have run this DEMO and tested over 100 Billion data Bits with no Transmission Errors over the distance of 10 feet from one Propeller to another Propeller. Here is a beta release before I place it in the object exchange.I am considering making a microSD add-on board with a difference... - ~0.8"x0.7" (~20x17.5mm) pcb smt - microSD socket - Propeller chip - Xtal (non-socketed?) I think 6MHz because they are cheapest - 24LC64 (8KB) eeprom with SD boot code - 1/2/3/4 wire connection to your propeller board (various protocols) - requires 3V3 and GND (i.e. no regulator on the pcb) Purpose... To provide fast and buffered connection to the microSD card. The included prop can read ahead and write behind, compare before writing to save wearing out a card if write is not required. Interface... 1pin for simple and therefore slow interface ...With the beta of Propeller GCC, and in the announcement of the beta of Propeller GCC the mention of 'all the development will be fed into Propeller II', I have some questions about the future that perhaps someone from Parallax can answer. I apologize in advance if this is answered somewhere else, but I couldn't find it. - With the advent of GCC for the Propeller, will further development continue on SPIN for the propeller, and more importantly will Propeller 2 be a GCC / Assembler only chip. Is SPIN going to continue on to the next generation of chip? ...Hello hoping someone on here can help me. I have an old BPI-216 serial LCD that I used to use for Stamp projects and now I want to use for a Propeller project. But I cant seem to get it to work with the Propeller at all. The LCD works fine with my Stamps and in its test mode. I downloaded the code from column #134 of Nuts amp Volts of BASIC Stamps, featuring Propeller Projects "Spin Baby Spin" which contains a demo for the BPI-216 with a custom object for it. Everything Ive read about the Propeller indicates that ...So this is something that I have been giving alot of thought too lately. What would it take to get more I/O lines with the propeller that are reasonably quick closest to directly attaching something directly to the propeller? Heres a case use to make the question more clearn. So lets say your building a board and you want to put a few expansion headers on it lets say 3 or 4 headers/slots with somewhere between a 4-16 pin interface. Now the propeller obviously only has 31 io lines so if you hooked vga/sd/keyboard up there is no way you could ...Hello, The problem I want to address: I want to build a robot that will run 5 Propellers in parallel. Each Propeller has a specific mandate (and many concurrent tasks are done by each propellers). Prop. 1- Control motors to move the robot Prop. 2- Power management Prop. 3- Image analysis (1 camera) Prop. 4- Sensors data analysis (distance, ...) Prop. 5- General tasks + robot mission Propeller should be able to communicate directly with any other Propeller at any time. Actually, I need (would like) to create a "fully connected network of Propellers". I think I2C is probably the ...For a project that I can't be too specific about at the moment, I am looking for a Propeller board like the SpinStamp, but with through-holes instead of the soldered-in pins. Non-Parallax products are fine, but they have to be: a) In *commercial* production, now and for the near future (minimum 6-9 months) b) In inventory of at least a hundred units, with reasonable lead times (lt30 days) for new inventory as needed c) Fully featured, with its own regulation, EEPROM, crystal, etc., just like the SpinStamp d) Orderable by consumers in quantities starting at 1, from the Web with online payment tools (PayPal, ...We had little trouble connecting a PS/2 keyboard to the demoboard, but we can't get a USB keyboard working. We've been trying to connect it to the Vinculum chip on Memory Stick Datalogger. We've been really digging into the USB HID spec. There ought to be a way to do this? Does everyone who connects a keyboard to Propeller use PS/2?About a month ago I bought a proto board but didn't need it until tonight. Alas, when I tried to use it tonight I discovered that it doesn't work. I know there's a problem because when I connect it to my computer via a prop-plug the propeller tool can't find a propeller. I checked the prop plug on another the pe lab I have and it worked fine there. Anyone interested in a prot board that doesn't work? From now on I'm going to test everything the day I get it for proper operation. Oh well.I can't make sense of what the Propeller data sheet has to say about power consumption for the Propeller, so I thought I'd ask for a ballpark estimate here. I want to run a Propeller Protoboard in a repeat loop and provide a single PWM signal at roughly 500 Hz, ~5 % duty cycle. The PWM signal drives an application that uses very little power, so that part of it is not a concern. I would like to know approximately how long a Protoboard will last on a 9 volt PP3 battery. Hours? Days? Months? Right now I haven't got a ...I'm designing a new kind of Propeller sticker for attaching multiple props together with wiring/pin information for a parallel machine, and put this list together with links to existing prop stickers etc. Any new prop sticker designs?

Has it being done ? or documented ? ThanksIn a project I am developing I am looking to incorporate the FTDI FT232R series chip for a USB interface. I was looking at several circuit designs and I noticed several variations regarding the I/O voltage interface to the Propeller RX / TX pins. In Ray's Logic PSB board he uses a FT232RL but according to his schematic does nothing with the 3.3 volt output from pin 17 but instead uses the USB 5 volt supply to feed the VCCIO pin 4 and then uses a 1K resistor to limit voltage to connect to the Prop on the RX and ...
