    08M strange power up

    If the resistors are not there, what exactly is the picaxe doing when first turned on? It seems to run the program after several seconds. Is it waiting for a time out, on the serial port, if no data on the serial port appears?

    Picaxe self on/off power

    The attached schematic shows how to have a picaxe turn on and off its own 5vdc supply. External components: H11B1 opto isolator 2N2907 transistor 10k resistor 330 ohm resistor

    Yep. That's what it was. Thank you

    08M strange power up

    The 08m is programmed on a programmer I built and then moved to a bread board. No I don't have the 22k or 10k connected. I will do so. Thanks. I'll have to remember that one.

    08M strange power up

    I'm running this simple program on an 08M. Main: high 4 high 2 wait 3 low 2 wait 3 low 4 end I'm assuming that on "power up" the 08M starts running it's program immediately, yet it take eight or nine seconds to start running. Am I missing something in the program. I've worked with 08M's before...

    Controlling a stepper motor/motors (21-02485-03 and a 28YBJ-48) with a 08M or 20M2 Picaxe

    Attached is a PDF of several schematic showing the wiring to connect the steppers and also the programs: One 21-02485-03 stepper being directly controlled/driven by an 08M Picaxe. One 28YBJ-48 geared stepper motor being controlled by a 08M Picaxe and driven via one ULN2003 chip. Two 28YBJ-48...

    running a stepper using high/low, problem

    I'm using a Windows XP laptop and had to get some files from Microsoft and download them to the laptop before I could install the Editor 6. I had version 5 already on the laptop, but I think the new M2 models are not on that version, that's why I had to use 6. I've got the all the stepper...

    running a stepper using high/low, problem

    I'm using real hardware. The editor wasn't set up to open automatically and I couldn't find any reference about monitoring, on the Editor screen. I put "#terminal 4800" in the main program, like you suggested, sure enough it came up. I had to change the setting to ASCII and can now finally...

    running a stepper using high/low, problem

    I'm trying to read a 10k pot connected to +5v and common, with it's wiper going into C.7. The program is as follows: readadc C.7,W12 W6=W12*200 sertxd (#W6,CR,LF) I entered this and monitored the "code explorer" W6 just registered zeroes. I tried with the "debug" selected and not selected. Is...

    running a stepper using high/low, problem

    Been doing yard work. I stumbled across the fact that you can, IF pinc.1=1 then :W1=15. I'm trying to use the Editor to monitor the values in a running 20M2 picaxe. I've done this before, but can't remember how I did it. I got the stepper program running, I'm using the pot to set the number of...

    running a stepper using high/low, problem

    Thanks for all the suggestions. Since I'm running the steppers, one at a time, I'll try the binary method and fool around with that. But before I do that, I'll speed the processor up to 32Mhz just to see if that gets rid of the pulsing, LED's, just out of curiosity. I would have been nice, if...

    running a stepper using high/low, problem

    Maybe someone can shed some light on this. I'm running two stepper motors using an 20M2 via two ULN2003 boards. You know the ones with the LED's' and connectors. I'm controlling the steppers by doing in a typical "high b.0: low b.1: high b.2: high b3 then a pause. This is done for every step. I...

    Program ceases running momentarily when serial comm. is interupted.

    Thank you very much. I'll do that and remember it in the future.

    Program ceases running momentarily when serial comm. is interupted.

    I was wondering if someone could explain this phenomena to me. I have a picaxe 08M running a stepper motor. The programming cable is connected from my laptop to the 08M serial port. The 08M program is running fine. When I turned on my laptop (windows XP) the 08m program stopped running for...
