    X / Y Working round integer maths to simulate floating point...

    A cheeky ask... I am trying to output the result of X / Y. I suspect it would be easy using a Floating Point Unit or FPU and then picking the digits one by one off the left of an output string discarding initial zeros. That it what I would do in my other programming domains. But, this needs to...

    Is this a known Bug in 'Time' or is this just me?

    OK I am making a rate meter. 18M2+ chip When I run it in what I call 'One Shot' mode it malfunctions. I think my logic is OK. What I am trying to achieve, in 'One Shot mode' is measuring a rate for a period of time, then stopping it after a defined period of time, (time needs to stay fixed) and...

    Serial Communication Input and Output, compare and contrast commands...

    Can you point me in the right direction please? I see several ways of serial input and :confused: output. I think I understand the pin limitations of some methods and the baud speeds available, but can you explain the strengths and weaknesses of the commands Serout, SerTxd and Hserout. For...

    Small solid state calibrated radiation monitor (gamma, beta, x-Ray)

    Overview... Ok. The proof of concept bit is finished, it works, but it is still being enhanced and its performance is being explored and it is not in a box yet. I could not find anything quite like this in the projects, so I thought it was worth posting. The concept... To make a simple accurate...

    OLED versus LCD Display and power consumption.

    When selecting a serial display to buy for a battery powered project, power consumption is crucial. I have read the specs of the OLED displays in the shop and the description clearly states in several places they draw less power than LCDs making them more efficient than LCD! I can't imagine how...

    Pulse Counter (using 18M2+) on an interrupt routine.

    Simple question, perhaps the answer is not so simple? Can you give me an idea of how wide in time a pulse must be to be reliably caught every time by an interrupt routine? Might a short pulse of 40 microseconds be missed, if the interrupts are polled after each command runs? My application...

    Gosub nesting limit. What happens when you reach it?

    I have a complex program, but one that worked. I then wanted to add another 'twiddly bit', I put it into another GoSub routine, thinking it would be easy to identify and test the new bit. It would not work. Bizarre things happened when the new routine was triggered and specifically when it...

    Neat Chips and Components to Inspire Picaxe Projects. Niches defined and filled.

    I'm not sure if this thread will run. We all should be familiar with the Picaxe sites selection of chips to complement these remarkable little microprocessors. I'm wondering what your favourite supporting chips and components are that may help others to get a project off the ground. Ideally...

    I have got confused with Ports and pins. Help Please.

    I have got in a muddle trying to move a program from one chip onto another. I built a project on the AXE50 board using 18M2 and It seemed simple to control outputs The 7 segment LED is labelled 0-7 and High 0 lights the Top segment labelled 0, High 1 lights segment labelled 1 etc. 7 lights the...

    Battery monitoring.

    Battery monitoring. (There is a happy ending!) I'm new to this forum and I have read the manuals but failed to find the answer to many simple questions. I think these chips are really neat and the forum impressive. Question 1 what is the likely consequence of enabling or disabling brown out...
