    ? PC cd-rom drive controller

    Dear all, If this has been posted before then please return me the link, if not: has anyone ever built a PC cd-rom drive controller with a picaxe to play audio CD's? I'd like to connect a picaxe to a stand alone PC CD-rom drive to control start, stop, next track and previous track. And, if...

    Daisy chaining 28X1?

    Dear all, Now the 28X1 has the SPI bus available I think of several daisy chained slaves with one master. Would this be possible? Thanks, Herman, NL

    maximal length of digital input line?

    Dear all, I have the Picaxe 18 Project board (CHI030) with all inputs modified for digital use. The ULN driver IC is fed by 20V and the Picaxe 18 by 5V from a 78L05 also fed by the 20V by a series resistor of 470R. The level of the input signals is 20V so a voltage divider is created by 33k...

    extended serial communication

    Hi all, For an application I need serial communication at 2400 baud with 8 bits + 2 stop bits or, equivalent, 9 bits + 1 stop bit. The Picaxe can only communicate with 8 bits + 1 stop bit. So I think an external hardware solution has to be made. Has anyone some experience on using an external...

    i2c bit banging

    Dear all, Does anyone know if there are any examples somewhere on programming a picaxe as an i2c slave device? There seem to be lots of examples about programming a pic as i2c slave but I don't speak the pic language. thanks, Herman, NL

    stepper motor wiring

    Hi all, I have the Astrosyn stepper motor (Y129-5) as supplied by my Picaxe supplier. I build the circuit as in manual 3 of the Picaxe manual but it does not work. When I measure the resistance between the wires I measure the following: orange -> yellow 182 Ohm orange -> black 99 Ohm...

    Bi-colour LED fun

    Might be obsolete. But, ever wondered how to alternate between the colours of a bi-coloured LED with two legs without reversing the polarity of the power supply? Just connect each leg to e.g. output pins 1 and 2, then toggle the pins in such a way that when pin 1 is high pin 2 is low or when pin...

    Serial Keyboard Emulator

    Hi all, Has anyone ever programmed a serial keyboard emulator into a picaxe? I like to do the following: send a character to a picaxe (e.g. an 18X) by RS232 communication, then the picaxe converts this character and sends it to a device on the output, for example the serial keyboard input of a...
