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.

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...

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.

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

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...

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...

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...

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...

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...

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...

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?

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...

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.

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...

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!
