BASIC Stamp Microcontroller

[cmavr8]

Hey guys, I can't make it work!
I get the "Error: No BASIC Stamp identified!" error, although I have done all the steps, including "sudo ln -s /dev/ttyUSB0 /dev/bstamp".

My dmesg gives

[ 3830.536104] usb 4-1: new full speed USB device using uhci_hcd and address 10
[ 3830.700882] usb 4-1: configuration #1 chosen from 1 choice
[ 3830.705536] ch341 4-1:1.0: ch341-uart converter detected
[ 3830.730779] usb 4-1: ch341-uart converter now attached to ttyUSB0

which means ttyUSB0 is the correct port.

Any suggestions?
(Using Ubuntu 8.10 and a usb to serial converter)

Thanks

What ever happened with this?

I let it sit aside for so long...

I may re-try when I get the time...

First, make sure you go through all of the install details on bstamp.sourceforge.net BASIC Stamp Tools for Linux

I was running into the same problems of the stamp not being detected. For all of your looking for a possible solution. This worked for me:

check to see if the stamp is connected (mine is via USB). If you have a USB version of the stamp you'll see a port assigned sort of like "ttyUSB0"

dmesg | tail

cd to /dev (you have to be a su to run the following command)

ln -s ttyUSB0 bstamp

Now try running your *.*tok file using bstamp_run yourfile.tok and see if it connects.

Thanks so much for the guidance!
I did what you said (installed the tools, tokenized code, linked USB to /dev/bstamp) but:

$ bstamp_run test.tok
Error: No BASIC Stamp identified!
Probably the stamp isn't connected, perhaps your stamp version isn't supported?
Try looking at the help, try 'bstamp_run -h' for more information.

When I connect the usb2serial adapter, dmesg gives:

[84464.000145] usb 5-1: new full speed USB device using uhci_hcd and address 3

[84464.309314] usbcore: registered new interface driver ch341

I can't see why it can't see it...
Even tried the bstamp_run command under sudo.
Any ideas?

Thanks for your time!

EDIT: I should note, that when I start the bstamp_run command, even if another program is running, it stops. I think this is normal for the stamp, but it still does not transfer the new program correctly...

I'm not a Linux expert, I just know what I tweaked to get my stamp working.

Do you see "ttyUSB0" in your /dev directory after connecting and powering it on your USB port? If so, then try removing using rm ttyUSB0 and run the ln -s ttyUSB0 bstamp again.

[cmavr8]

Yeah, ttyUSB0 work great.
I tried Putty and it can communicate with another computer's com port.
