    I feel your pain.... For me it's usually bad breadboards. So many hours wasted troubleshooting

    Harmonic series problem

    Hi Alan, Yes you're right - it seems like the adc value is almost redundant, and the frequencies end up just as a by-product of the code execution time. Thanks for the code suggestion. I think 50hz to 60Hz might end up too slow for the project though. Cheers Chris

    Harmonic series problem

    Hi guys Hope all is well, and glad to see Hippy back again these days! I'm using 5No 08M2's to generate sine waves in a harmonic series. E.g/ Pic 1 - f0 = 100Hz Pic 2 - f1 = 200Hz Pic 3 - f3 = 300Hz Pic 4 - f4 = 400Hz Pic 5 - f5 = 500Hz Have tried this in a 'do' loop: Do Readadc C.4, w1 PWMout...

    20M2 - using an idle timer

    Thanks both - I never realised there was a TIME command.A very simple solution!

    20M2 - using an idle timer

    Hi guys I'm using a 20M2 with an external clock input, which then triggers an output pin to light a few LEDs. The clock is manually introduced to the circuit and so there might be long periods of time where I'd like the LED to remain off, when the clock isn't being used. I'd like this time...

    LED Light Brightness Regulator

    Hi Bill I would use a regular Light Dependent Resistor (LDR) and use it in a voltage divider set-up. As the light fades it's resistance will increase, and you can use this in your circuit to send a voltage to your Picaxe. Use the 08M2 ADC input to monitor the voltage as it changes. Calibrate...

    Audio recorder module needed, any ideas ?

    Keeping a keen eye on this thread :) I've been tinkering with the ISD1820 myself lately. Looking forward to seeing what you come up with Buzby!

    Thanks alot guys that makes sense.

    Using 2 buttons in combinations

    Hi guys, hope you're all well If you have two buttons A and B connected to separate input pins, is there a logical way of achieving: While A is pressed and held (i.e pin A is high) then subsequent presses of B can act as one-shot inputs. While B is pressed and held then subsequent presses of A...

    "Need for speed" - help needed optimising code

    IT WORKS!!! 😀 Thanks Buzby. That has turbocharged the program. Going to start adding back all of the features I'd trimmed off. Cheers Chris

    Setfreq em64 !? 😮 I never realised it needed stating to activate it. Wow thanks Buzby that gives me some hope! Will give it a try Cheers Chris

    "Need for speed" - help needed optimising code

    Hi guys I've hit a speed wall in my program. I purchased a 40X2 with 16MHz resonator in the hope to include some extra code/features with an ongoing circular buffer program I've been working on to drive a home-made drum machine at the desired speed of 120bpm. A quick summary of the program's...
