A couple of beginner questions about the Propeller.
I am brand new with the propeller and have a question about line levels. I have prototyped a sample circuit with a 44-pin prop and an eeprom as shown in the prop manual. It shows BOEn tied Low with Vss and states that BOEn is active low, I see that this makes RESn an output and assume that BOEn should remain low for normal operation. I am using the prop clip for an interface so I assume after dumping the program into the eeProm the RESn line remains in a high state due to an internal pull-up…
Am I understanding this right?
Also I am using a 3.3 Volt (100 ma.) booster circuit to supply Voltage to the Chip via a AAA battery “I only have two LED’s attached to the chip for a simple test circuit but experiencing burnout problems with my booster IC. after about 4 or 5 dumps into the eeProm … Any suggestions?
Is there a way that I can monitor a single step through sequence to make sure that my circuit is working the way it should? The software is seeing my prop on com5 but my LED’S are not blinking the way the program is telling it to. I am using the internal Slow Clock mode …

I will be programming the EEPROM out of circuit so therefor I never need to reset the prop. What states should the RESn and BOEn lines be hardwired to? Tnx, WilliamI just opened the Prop, Prop clip, read the manual through, circuits etc. and read quite a lot, what I could find on these forums. So when the Prop boots up, Cog0 looks for a PC connection first. If it's available, it'll load the program into memory. This mean the EEPROM is optional as long as I have a good PC connection running Propeller Tool right? Is there anything I need to do to terminate those open pins on the Prop then? I'll have more, don't worryWill 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 ...In 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 ...Many have seen the development thread I started on my M44D40+ module and I recently showed them off at UPEW. I still have some modules left, so this will now be the official thread about any further development, feedback, etc. My module's features are: 1) DIP40 form factor, 0.7"x2.0" (0.6" lead spacing) 2) 44 pin QFN Propeller microcontroller 3) 5 Mhz socketed crystal (Samtec machined socket pins for firm contact) 4) Socketed 32Kb EEPROM, DIP8 package 5) Right Angle 4 pin programming header (Propplug compatible) 6) Two header options: a) stacking headers b) machine pin socket compatible headers (0.025"square top pin, 0.018 round bottom pin) 7) 3 bypass caps ...The Q44 Prop on by board has Ground going to all 4 VSS pins and the Brown Out Enable, 3.3v going to all 4 VDD pins, P28 amp P29 going to EEPROM, P30 amp P31 amp RESn amp Ground going to a propellor USB adapter, and nothing is touching the XO or XI pins. I'm getting 3.3v coming out of my unused prop pins, but when I connect my prop to the propellor tool via the mini-USB adapter it comes back saying it cannot locate a propellor on any port(Port 4). When I move the USB cord over to my ...This gets raised often, so here goes again... (this is my take on what happened) Chip realised that switching programs under windoze caused the comms status pins (DTR amp RTS) to be reset when the COM port was released by a program. The next program would presumably then make these signals active. Under normal circumstances, using the DTR or RTS pin (at TTL level) would cause the prop to reset. When downloading a program to the prop it is normally held in SRAM and we do not bother to program the eeprom (it has a large but limited number of program cycles). ...I have a prop circuit (see below) that uses a dual channel Vishay ILD213T optocoupler to interface a prop output and input to an external device requiring and returning a 5v signal. I have a separate (but not isolated) 5v supply for this side of the interface. I need to (occasionally) power the +5 side on and off via a prop pin. The 5v logic and load will draw less than 15mA. Could someone recommend a solution? I'm not experienced enough with FETs and Transistors to know the best and most economical way to do this. A circuit diagram would ...I am wanting to use the MCP73831 to charge the Li-Po battery running the propeller. I then want to use the MCP73831's State line to tell the propeller when the battery is charging (so I can display a charging icon on an uOLED display). The data-sheet for the MCP73831 states that the State line is tri-state logic (VSS-NC-VDD). It also states that it can be connected to a microcontroller if pulled high (presumably to make it high when in the NC (floating) state. My question is, what effect will this have on the propeller if the state pin switches between VSS, floating and 5V, ...I did a search on digital POT's for the propeller chip but only found a driver for a MCP4141 which is acting a little weird( see note 1). Also there is mention of pull up resistor on the CS pin and I don't see it being used with any other micro, with that chip. Is it required for SPI? I do remember pull-ups being used on some SPI sd cards. I have to control a set of LED lights with 0 to 5VDC and I'll keep experimenting with the MCP4141 for now but would like other options in case I ...I'm currently experimenting with extremely low power solar powered circuits and decided to test if I could use a Propeller in the circuits. Figured the tests would be useful to someone else so I'm sharing my results. My test setup consisted of a DIP prop on a bread board with boot EEPROM. The brownout detector was disabled for all tests (unless otherwise stated) and reset was pulled high with a 2 Mohm resistor. Initial tests were done with a 100 ohm current shunt, but voltage drop during bootup and resolution were poor. I repeated the tests with the setup in ...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 ...--------------------------------------------------------------------------------------------------------- My initial question has been solved several times over. Thanks everyone! See post # 21 for Beau's push on/off circuit challenge --------------------------------------------------------------------------------------------------------- Hello everyone, I've been a long time lurker here. I have not yet had a question that I could not find an answer to by searching. I now have an excuse to post I have been playing with Xbees and Props amp have some wireless control projects in mind. I'm putting together a handheld remote amp would like to power it with a single 9V battery. In an effort to make the battery live more than a couple days I have ...Thinking about a board with both a Propeller and VNC2 on it... I think most of us use the FT232R to program the Propeller. But, it's also what is used to program and debug the VNC2... Just took a look at the idea of using a single FT232R chip for both... I think it's doable. The Propeller is a simpler interface actually. One thing that concerns me is that the VNC2 programmer has DTR connected to DSR and CTS connected to RTS. I'm not completely sure what affect, if any, that will have on the Prop Tool... I guess another question is: Can I use the ...Ok so I finally got all my stuff in the mail, I built a simple power regulator circut on some pref board then followed the simple propeller schematics on in the prop manual, have not added a crystal yet though. When I hit f7 spin tool says no propeller chip found on com 3, but when i use the serial terminal and type RX, and TX both light up, when i hit my reset switch RX, flashes, when I hold the reset button as I type only TX will flash and RX stays dead until I let go of the reset. ...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 ...ok i have a few just sorda random questions about things that dont really require there own thread. first off what is a line driver used for? more specifically a tri state octal buffer like the one parallax sells http://www.parallax.com/Store/Compon...3/Default.aspx i see these sort of chips everywhere.. ive been tearing apart old 486 and p1 mobos and there all over the place. i see them in alot of projects too. i read the data sheet but that didnt really give me an idea of there genral use either. from what i can tell somehow maybe there used to save data pins and create ...So, the issue is simple: When I plug a TV into an RCA jack I soldered onto my proto-board the Prop Chip resets. I think this is due to the ground planes being different. I don't really know a good solution to think problem. Not all TV's I plug the prop chip into cause the prop chip to reset. Any suggestions? More capacitors near the prop chip? I have 1 uF ceramics on the 4 power lines and 0.1 uF on 2 of the 4 power lines. Should I put some 10 uF caps near by? Thanks,I have a robot that I'd like to be able to monitor the 12v battery voltage on. The motor controller has all this built in, but I want redundancy built into my telemetry. I have a couple pins left on the Prop, is there an analog circuit I can build to monitor the battery? It could even be as simple as a High/Low indicator with .5v accuracy.Is the Quickstart the cheapest Prop board being sold? I think it's $25 from Parallax, more through other vendors. The new FTDI FT231 chip has me thinking about how cheap a Prop board could be... I also noticed yesterday that Digikey has Props for $5 in qty. 100. Haven't gone through the numbers extensively, but it seems that very basic Prop board could be made for ~$10 in parts... $5 Prop $2 FT231X $1 USB connector $1 EEPROM $1 Crystal + passives Add in a dollar or two for the PCB and maybe you have something that can be sold for $15?
