    Programming Adafruit 4-Digit Displa7 (HT16K33)

    Hi All, Well, I'm at my wits end, so I thought I'd ask the experts. I'm attempting to use an Adafruit 4-digit display that uses an I2C IC, specifically the Holtek HT16K33. I haven't located any PICAXE code for this, but I've poured through the datasheet and attempted to reverse engineer the...

    Mini Jet Engine Control - Measuring High Temp and Speed

    Hi All, A buddy is interested in some help making his own controls for a small jet engine. While the one he'll be using is normally for RC planes, he plans to put it on an RC boat. I'd like to ask if anyone's had any experience interfacing high temperature sensors and high speed rotary...

    2-Line Serial Backpack

    Hi All, I've been working with another member to develop a cheap serial backpack for LCDs. We came across a recent article in Nuts & Volts that uses two lines to communicate to an LCD through a 74HC595. The code was written in GreatCow Basic for a PIC and after much trial and error, I...

    Using USB Programming Cable, TTL-232R-5.0V

    Hi All, Finally got my first set of PICAXE chips and I was hoping to avoid the expense of buying the USB PICAXE programming cable as I already have some RS232 to USB cables. I'm trying to use an FTDI TTL-232R-5.0V cable to program the PICAXE, but I'm not having any luck. I'm using the 22k and...

    Button Inputs Occassionally Not Detected

    Hello All, I've finally gotten my first PICAXE program to function the way I'd like. The only problem at the moment is I'm using the button command to check the status of four buttons and while this works most of the time, once in a while the button press is not detected and must be pressed...

    Countdown Timer Using MAX7221

    Hello All, I'm new to PICAXE but I've written several PBP programs in the past. I'm working with Tracecom to help someone on another forum with a project. The other member doesn't plan to get into uC's much but wants the ability to modify the code so a PICAXE seemed like the ideal choice...
