Picaxe Cloud not seeing hardware

I am trying to program a picaxe using a raspberry pi5.
I loaded chromium and signed up for picaxe cloud
I have set up a USB port (checked it using terminal in cloud and it is working) and plugged in my AXE027
when I try to program my chip I keep getting "hardware not found"
I am at a loss of what I am doing wrong
Any advice greatly accepted
 
Where is the Picaxe chip mounted? Is it on a breaboard?
Have you tried hard resetting the Picaxe chip (remove and put back the power) just before you upload the new code?
 
If it's a unprogrammed PICAXE do you get the "Hello, I am your PICAXE" message in the terminal?

I'm not familiar with your setup but as the chips are fairly robust it's usually some types of running program, or possibly download corruption, that can cause this issue and a hard reset is the answer.

You can monitor Serial_Out with an LED and resistor to 0V. An unprogrammed PICAXE will flash every second, a programmed chip may be silent or be seen chattering. After a few seconds you can raise Serial_In to logic high and the LED will flash every 3 seconds if it can respond to what it thinks are soft-resets (download requests).

I did some work on Wireless Terminal/Download comms earlier this year and was distracted to other work after getting the 1st bluetooth connection working. I aim to pick it up again next year but the attached gives some insight to the PICAXE download workings.

Hi,

"Hardware Not Found" is usually an indication that the Serial Port is not set correctly (in the Program Editor), or the PICaxe's Power Supply is not functioning adequately. The standard PICaxe Editor provides a LoopBack Test and other diagnostics aids, but as you're not using a "normal" Windows installation, I'm not sure what is available.

However, the installation of the AXE027 does seem to cause a number of people problems (apparently it requires a "two stage" process), even with Windows, so a forum search should find plenty of associated threads (perhaps too many).

Cheers, Alan.

Thanks for the download, it looks very interesting.
 
Hi,

I don't use the axe027, I prefer an FTDI board coupled with a hex inverter. The difference being, the PID of my board is the standard 6001, which just works in linux with zero hassle and nothing to do.

I just signed up for Picaxe cloud and my 20x2 worked immediately on my pi5. I just changed the port to ttyUSB0 and selected picaxe 20x2 and away it went.

My version of Chromium: 139.0.7258.154.

Do yourself a big favour and use Picaxe's axe 027-programming tool to change your cable's PID to 6001 and you'll be good to go.

Make sure you're in the dialout group:

groups $USER in the terminal

If not:

sudo usermod -a -G dialout $USER

Good luck!
