    Getting AXE027 working

    Hi Buzby, Hippy, Success!! Thank you for both taking the time to reply. Buzby, your comment that the cable passed the hardware test was very reassuring. This forced me to go looking elsewhere, rather than assuming that the problem was with the computer. I tried a second -08 chip I had- but...

    Getting AXE027 working

    It is many, many years since I have used a PICAXE, but I now have a simple application for using one. I found some -08s in the junk box, which I had forgotten about, but they will be ideal for my application. I decided to start by programming one with the simple Flashing LED program to make...

    Reading inputs on 28X2 port A and some of Port C?

    I used several smaller PICAXEs about five years ago for projects, but I have not done any more with them since then- until now. I am doing a project using a 28X2, because I need to use almost all the I/O pins. I am absolutely fine with the hardware aspects, but very rusty with the programming...

    Out B.x for an 18M2

    This seems such a simple problem that I feel embarrassed about asking it, but I cannot solve my problem. A few years ago, I did several projects using 28X1 chips. These projects included 2 row by 16 character displays. I wrote my own program to drive this display. Now, I want to do a project...

    Saving software changes

    After a break of several years, I have got back to PICAXE for a new project. As I am now using a new computer with Windows 7 (instead of XP and a serial port), I have therefore had to use the new Editor (V 6.0.5.9 Beta) and install the USB cable driver (AXE027) in. (Why oh why does this AXE027...

    Basic i2c problems and questions

    I have done a few successful PICAXE projects, although my programming skills are not particularly good. I am now wanting to do an i2c project for work. So far, everything is looking good, except for getting the i2c driven 12 bit ADC working. I have bought a Linear Technology LTC2305 demo...

    Pins, LCD and Manual 3

    Have I missed something? I have been using an LCD panel with a 28X1, and controlling it using the PICAXE connections and steps broadly as described in Manual 3, at around page 39. My understanding is that the "pins" command works on all 8 input or output bits simultaneously. In the Manual 3...

    20M- programming?

    Have I decided to use an orphan? I can not see how to use the latest edition of the programming software to work with a 20M chip? I have not been able to get any references using the Search facility. Solution? Thanks

    ADC reading stabilty- suggestions?

    I am using the ADCs in a 28X1 in 10 bit mode. I am not happy with the stabiltiy of the ADC value I am seeing. I suspect it is a hardware issue, since, when I use a voltage divider from Vss to ADC1 and from ADC1 to Vdd, I get a reading which does not vary in the last place. When I use my...

    10 bit ADC result stored?

    I am wanting to change from using the 8-bit adc to a 10-bit adc in an existing 28X1 program, by changing the "readadc" statement to a "readadc10". The 8-bit read requires one word for the result. But a 10-bit read requires a word plus 2 bits. Where are the additional 2 bits stored? Is there...

    Memory Words, Bytes and Bits

    This is a very naive question, but I can not find an answer which I fully understand and can feel confident about, when writing my first piece of code. This is despite Searching through the Forum. It concerns bits, bytes, words and variables. A word consists of two 8bit bytes. The manual...
