    Recording to an SD card in FAT32

    I do love a challenge - especially when it works!! I have, over several months, been developing a programme that will write data to an SD Card in FAT32 format. It has not been an easy ride and did feel like giving up at times. I am please to say that I persevered and now the programme is...

    Fill an EEPROM with data from a computer

    I have two LM386 audio amplifiers being fed from an MP3 module. Everything is working well on the prototype apart from the switching arrangements. I have a 5v supply to the picaxe and a 9v supply for the LM386 I need a picaxe to turn on the power supply to the amplifier so that it can be used...

    Interrupt on 18M2

    Please can someone tell me if it is possible to pull and 18M2 out of sleep with an interrupt. Looking through the manual I can only find reference to this with the X2. I need to pull an 18M2 out of sleep when an 08M pulls a pin high so that it can subsequently send a serial signal with an...
