    Problem with switch timing

    Problem with switch timing [SOLVED] I have an intermittent fault on a circuit with a Picaxe 18M2 It uses two manual push buttons and drives a motor that opens and controls my curtains. There are two additional open and close stop switches, these are reed switches activated by a moving magnet...

    Can I Program Picaxe if Supply Voltage is only 3 Volts ?

    Currently I'm running a Picaxe 18M2 from the 3.3V supply of my Raspberry Pi. The Picaxe was disconnected from the Pi and powered from 5Volts and I used the AXE027 lead to program the Picaxe. Is it safe to program the Picaxe if it was connected to the Raspberry Pi and being powered only on...

    Minimum Power Supply Voltage when Programming M2 Picaxe

    In Picaxe Manual 1 page 25, M2 and X2 parts can work between 1.9 and 5.5V However if the power supply was3.3V would programming a 20M2 Picaxe cause damage as the AXE027 USB lead supplies 5 Volt? I've already killed a 20M2, because I missed off the 22k/10k resistor network to serialin. My...

    Picaxe Programming Editor 5.5.1 on Linux

    Will there be a linux version of the Pixcaxe Programming Editor? The simulator is very useful. I thought I'd give thewindows version a try using Wine 1.4 and PCLinux. It installs properly asks for name and company but when run fails with a RunTime error 339. wave32.ocx missing or corrupt. I...

    Ways to Display Power Supply Voltage

    I don't know what the maximum input voltage is per pin on a 20M2 picaxe, but if the picaxe was powered from 5V and I wanted to read a 15V supply then I would use an attenuator of say 4.7k resistor pin C.1 to Ov and 10k resistor from Vcc to pin C.1 This would give 4.79 V on pin C.1 (no load or...

    Serin and Serout Timings

    For all M2 picaxes e.g. 18M2 if I dont use the setfreq command the picaxe will run at 4MHz What is the difference between these commands, if used with a picaxe running at 4MHz: serin B.0,N2400,b0 and serin B.0,N2400_16,b0 2400 is still 2400 baud but will the frequency suffix ( e.g. _16...

    Bidrectional Serial Link

    This is my first project and although its working, I am having some intermittent problems. I am using a network of Picaxes to signal Intercom data, over 2 wires, (bus) and Ov. My test setup is just 2 stations. Signalling from Station1 to Station 2 works, every time, however from Staion 1 to...

    Picaxe Online Shop Question (please move or delete if inappropriate)

    Made an online order about lunch time today, and realised I forgot to add a couple of items. Does anyone know how long it takes to dispatch an order, or if there is an email contact to possibly add a couple of items? Moderator Note: Please delete if this question is inappropriate, I can always...

    Table and ReadTable commands

    Looks as though I have some older Picaxe 18M2 chips. When I try to use Table and Readtable commands the Linaxepad compiler give me this error: Error: 18M2+ only commands cannot be used on older 18M2 parts! Picaxe manual 2, page 179 does not mention the Picaxe type for readtable and table...

    Storing and recalling ASCII Strings

    I'm looking at ways to store and recall strings of ASCII text on a Picaxe 18M2 I know I can store a string in EEPROM with a start address, e.g. EEPROM 10,("Voltage VC1=6.23") I am also assuming that this will require 1 byte for every character (including spaces) 16 bytes for above example...

    Serout and SerIn Command on Picaxe 18M2 and 20M2

    I need to send serial data from one micro-controller to another. Both chips will be same type , either 18M2 or 20M2 Page 204 and 208 of manual 2 describes the serout and serin commands SEROUT pin, baudmode, (data) e.g. serout 7,N2400,(b1) would transmit the data stored in variable b1 out...

    Picaxe 18 Tutorial Board AXE050U

    I bought a Picaxe 18 tutorial board, some months ago, just started using it. Mine has the older Picaxe18 chip installed. On the tutorial board are 3 push switches, 1 LDR and a 7 segment LED display. I've just checked through the PDF manual but cannot find which pins of the Picaxe18 connect to...
