    Automatic "zero-point" detection, how?

    In another thread, I solved, how to utilize Picaxe's TOUCH -command to detect something else than living material (dry "dead" material, water level) It seems, that "real world" apps (sensoring) is not as interesting in this forum, as coding. That is why, I am starting a new thread, for the...

    18M2 touch, details wanted/given

    18M2 touch, details wanted/given, SOLVED SENSORING LIQUID/DRY MATERIAL Just got my first M2 chips, and had afew hours to experiment with touch sensors. Seems promising, that the chip could sense also "more difficult" objects, than human parts... My project is to sense level of non-conductive...

    different chip versions - choosing/tips

    PROLOG: (TRYING to keep it short) Less than two months ago I first "found" Picaxe chips, and saw the potential: here is the means to do the projects I have had in mind (with Picaxe, do-able with my skills,which do not include assembler code). BEFORE really starting to learn Picaxe coding, I had...

    push-button circuit - a question

    I've already made/tested a bunch of Picaxe circuits, that use pushbuttons for various reasons. Connected the "usual way": button between Vdd and inputpin, a 10K pulldown resistor between inputpin and ground. In the code, handled the "bounce" with pause 25. BUT not until today have I noticed...

    problems-win7 32bit

    I have tried all I can... reloaded and reinstalled, no use. The problem is, that in BOTH, programming editor AND winaxepad (newest ones),any operation ,that needs "options"-window takes 1/2 to 2minutes (on the titlerow is the text "program not responding".Usually, not always) AND both programs...

    Very simple DAC - 2 solutions here

    Saturdays project, dac's... 0-10V output is needed to control various equipment. Output voltage has to be rail-to-rail, and with good resolution. If we don't look at adding an external dac-chip (that is covered well by Westaust55) ,there is still pwm-command... If one is carefull, the command...

    Backlighted LCD - one solution

    There have been questions about "fitting" LCD's and backlight wiring on AXE033. Here is a little help. If someone has done like me, made some boxes for Picaxe products (using AXE033), wouldn't it be nice to find a lcd, that fits in the same hole than ACM1602B (the one delivered with AXE033)...

    simple DAC with DS2890 - done

    My project today was to make a working setup of DS2890 digital potentiometer ,with Picaxe. Goals: -To learn using ow-commands. (I am quite new with Picaxe, and manual is not much help with those commands...) -I have seen quite many questions about a SIMPLE dac in the forum... DS2890 can accept...

    readtemp takes 750ms - utilizing the time?

    EDIT:WHAT WAS ACHIEVED IN THIS THREAD. -new code to read temperature in 100ms (9-bit resolution) -several codes to translate DS18B20's temp readings to degrees I wan't to confirm, that I have thought right... (or wrong) Most examples show someting like this. Readtemp 1,b0 pause 750 use the...

    eeprom adresses for data - howto?

    I am working on some control devices, powered by mains only. NEED to retrieve a few bytes (1-5) of data after a mains down. (so that program could continue from "where it left", and to storage "user settings") When got in programming to the state, where that was needed, I was surprised, what I...

    ADC-improving stability by math

    This is an idea / a project. Haven't yet even thought if it is possible with Picaxe, but still I tell what I've been thinking today... Very often, when reading a sensitive sensor with ADC, one gets quite many "wrong readings", too. Normal way to smoothen things is to take average of, lets say...

    X2 adc voltage reference

    According to manual2, adcsetup-page, there IS a way to use external Vref for ADC. As a new user of Picaxe, I need some feedback from the more experienced users... Have I understood correctly: If i put a resistor divider (10k-10k) to Vref-input, I get full adc-reading at 2,5V? This would help...
