    The main problem I would guess is there is no PAUSE command before your GOTO MAIN at the end. This means the program runs incredibly...

    An RTC doesn't have the current local time programmed into it when delivered but it can have its time programmed. That can either be...

    I couldn't even find a 26C16 datasheet via Google, but if it is a good old fashioned parallel EPROM I would suggest you would be better...

    Never used the DS3221 or alarm functions but I'll have a read of the datasheet and see what I would would best guess at. Others are more...

    hippy replied to the thread Picaxe Timing Accuracy.
    It's not clear why you would be storing data at address 0 through 11, why there's so much data. Or why there's any need to store any...

    That could be a problem. The way multi-tasking works is it executes one command from one task, then executes one from another. That...

    You could potentially 'dither' the outputs with an appropriate RC filter; continually switch between two levels to achieve a third. For...

    A year is 365*24 hours = 8760 3 hours is (3*100)/8760 = +/-0.034% A PICAXE has an internal oscillator with +/-2% accuracy. I have...

    hippy replied to the thread Understanding max min.
    MIN means ensure greater than a minimum. 4 is bigger than the minimum 0 so it remains as 4. When you subtract 'b0', if that's greater...

    hippy replied to the thread sim900.
    It is more common to connect hSerOut to an RXD pin, because that's how it is from the device's perspective, but sometimes a pin can be...

    hippy replied to the thread sim900.
    HSEROUT sends the "AT", everything received is automatically handled by the background receive code by the PICAXE firmware, specified by...

    hippy replied to the thread sim900.
    That would seem to be correct. I would double check the wiring. Especially that the wires are not crossed over. You shouldn't receive...

    Start with something a little simpler - #PICAXE 28X2 #Terminal 9600 hSerSetup B2400_8,%001 pause 2000 SerTxd ("Started.....",cr,lf)...

    Post the full code you are using and we can check if it looks like it should work, and what you should be seeing.

    hippy replied to the thread 14 m chip coding.
    The 14M has fixed inputs and outputs, the 14M2 allows more flexible configuration of which pins are used for input or output. So long...
