    An occasional keyboard?

    There is the option also to use a USB keyboard that has the ability to fall-back to PS/2 mode. You can connect those keyboard either using a female USB connector on your board or using a combination of a PS/2 port an a PS/2-to-USB adaptor. IchigoJam is using those type of keyboards.

    Light Chaser; Preloading EEPROM data

    I also needed to do a similar thing for a smart toy and I was thinking of either using a serial eeprom programmer or use a side loading program running on Picaxe. I end up using the side loading program and another liberty basic program to read the file with the data and push it through the...

    14m2 and Touch16 'channels' ids

    Thank you for clarifying this Technical. My main issue, though, was that B.4 didn't seem to be able to work as a touch sensor and that was tested on 2 different chips. I did get a value back every time I used the touch16 command but the value didn't change when I was touching the pad.

    14m2 and Touch16 'channels' ids

    Technical, any ideas about pin B.4 and touch16 command?

    14m2 and Touch16 'channels' ids

    Alan, I am using touch16 already, it's easier to detect the 'touch' on the pads based on the size of the copper pads and the 4mm plywood in between. Currently, I just check the value of the touch against a fixed value, that I managed to find out during the calibration. I do have the available...

    14m2 and Touch16 'channels' ids

    I know what you mean Alan. I had a look at the application notes for capacitive sensing, had some great tips on the size, distance, in between material, so I already know what I had to expect. I wasn't expecting to have a huge variation on the values when switching from headphones to a line in...

    14m2 and Touch16 'channels' ids

    I did the syntax check trick, the results don't make any sense. So, nobody uses touch pins on Picaxe? Is it maybe 'cos of the calibration hell? Different values when using a power bank, a powered USB hub or power from a 5V phone charger. Not to mention the mess in the touch values when I connect...

    14m2 and Touch16 'channels' ids

    I tried cross checking between the datasheet and the 14m2 pin out, but it didn't work. For example, I don't get to use channel ids 6 or 7 (I get compile errors) but 8 is available which, on the other hand, is not defined in the datasheet. That means I have no clue where channel 8 is mapped to. I...

    14m2 and Touch16 'channels' ids

    Hello all. I am making a small audio player using the Picaxe 14m2. For the control buttons (play/pause/prev/next/stop) I am using the touch capabilities of the chip. I saw in the picaxe site that the command refers to 'channels' and not port names but I couldn't trace any details on how the...

    What's next after M2?

    Hello Technical, thank you for taking time to reply to this thread. Yes, I do understand the effort required to include a newer chip in you range. Still, I more interested in the features that you wish to include in newer chips. As Buzby said, there are new peripherals available on the Pic chips...

    What's next after M2?

    The trademark on Picaxe and who actually owns it is indeed weird. But this is something between RevEd and Microchip Technologies. I only care about RevEd and us, the customers. Alan what was that 'new' product that had a 8051 core?

    What's next after M2?

    It's been 9 years since the M2 chips were released, at least for the 8, 14 and 20 pin versions. Since then I haven't seen any announcement on this forum for new chips to be released. Don't get me wrong, M2 chips are still a great option for doing quite a lot of things, but looking at similar...

    IR decoding

    Yes, that one! Madeby Fotorama. You can get this toy in my country (Greece) for less that 10 euros. I have decoded the IR data and I am currently using it to turn remote Rd plugs on and off. I am planning to write a description on the project at some point.

    IR decoding

    I like the price and the built-in ISP feature. I think I might order a few to have a go, just for fun. I still have some arduinos around to have a go with, which I haven't even touched yet. Every time I have an idea for a fun project I just pull out a picaxe from the drawer and start building on...

    IR decoding

    I don't think it's an STC chip. I just checked the pinout, I get GND on pin 1 and Vcc on pin 16. Have you used an STC chip? Any change this comes with a bootloader? They are pretty chip though!

    IR decoding

    Unfortunately, it is an unmarked 16pin chip. I tried sourcing the manufacturer/factory in alibaba or made-in-chine but no luck. Also, since this toy doesn't emit RF I couldn't find anything in the FCC site as well. It does make sense to use a simple serial protocol and cut down on development times.

    IR decoding

    Well, I learnt a new thing today! I will look up SIR to see if it matches what I have found already. The transmitter and the receiver don't use any IR decoding chips, e.g. PT2221/PT2222, it's just the micro controller, so it's all happening in the firmware. My guess is also that they tried to...

    IR decoding

    Hello all. I am tying to decode an IR toy in order to 'expand' it's uses. The toy uses a wand (ir transmitter) and a 'magic egg' (ir receiver). I used a logic probe to peek on the signals transmitted from the wand and then tried to lookup the start bit, pause, logic 1/0 bit duration in order to...

    Words&Letters - Connected wooden blocks toy

    Update: Source code is now attached in the first post! If you are curious to see how to emulate a keyboard using a picaxe with either AACKeys(windows/mac) or inputattach(linux) you can see it in the code.

    Words&Letters - Connected wooden blocks toy

    Hello all. I have been working on a connected educational toy for the past few days based on the 08m2 chip. It's the traditional wooden blocks game augmented with RFID tags and a companion HTML5 application. The RFID reader is connected to the computer, reads the tags inside the...
