    For PICAXE users on a budget: $8 USB to Serial Adapter Working for Picaxe

    With most new computers coming out without a traditional COM (RS232) port, PICAXE users must find alternatives to program the chips. The most reliable method is to purchase the AXE027 USB PICAXE programming adapter cable, and use it as directed. However, some PICAXE users simply cannot afford...

    Need Ideas to Interface Trolling Motor Switch

    I'm bodging together a high-speed electric trolling motor out of other trolling motor bits. For speed control, I am having to use a 9-position rotary switch with very non-standard internal connections. The switch has 6 tabs. I'm trying to come up with ideas on how to use a Picaxe 08M (I have...

    Is There a Way to Retrieve an Existing Program?

    I have an older 08M project from which I'd like to retrieve the code. The original code file has been lost through several crashes over the past few years, and the hardcopy has been eaten by Dr. Who or gremlins or little green men. Is there any way to retrieve the code from the 08M without...

    08M and 28X2 PULSIN differences

    This may be covered someplace, but I haven't found it yet. Ok, I am on the next phase of my life-sized RC boat project. This is my first adventure into RC with PICAXE chips. What I'm going to do is use (temporarily, for tests only!!!) an aircraft radio set I already have to get the basic code...

    Using Just 1 Pin To Handle Many Buttons

    This is copied from a reply I made in another thread, but I thought some might find it useful enough to warrant its own thread. You can theoretically use one ADC channel and a multiple-resistor voltage divider to read up to 254 buttons. I've used that trick myself for up to 8 buttons (for a...

    Spice models for PICAXE chips?

    Does anyone know of any Spice/P-Spice models for the PICAXE chips? I've never seen any. Is a Spice model (with the ability to plug code into the model) even possible for a micro-controller? I ask because plugging a PICAXE model into a program like Circuitmaker would be a great way to breadboard...

    Joystick control of 2 motors w/ 08M chips

    I have 2 DC boat motors that I want to control using only 08M chips. My current configuration is independent motor control with 1 chip for 1 motor (like a bulldozer or skidloader control scheme for example), each chip reading a single POT to determine direction and speed for its own motor. This...
