Back on the saddle again, but the pc_debug is baffling a bit ...

Hi all,

been doing some other stuff for a while, but now I have some time for propeller gain.
Bad news is that I pretty much have to start from zero again...

Debugging

---

Reading the posts I understand that other people are able to use the PC_debug object to send string to hyperteminal.
Sadly I am not.
Is it the 3-transistor circuit that i'm using or something else ?

Are there any persons using the 3-transistor SerialToPropeller and debugging happily ?

Would someone who is debugging succesfully with pc_debug explain his/hers setup ?

thanks,

OK , I get it.

When I was doing the Propeller-dance the first time around, parallax was out of prop-sticks and plugs,
so I had to build the 3-transistor programming-kludge.

Now reading the description on webshop about prop-plug:
"The Prop Plug and Prop Clip each provide a USB-to-serial port connection that is convenient for microcontroller programming and communication."

Judging from that it's quite clear that if you want the pc_debug object to work the
right setup to have is a prop-plug.

So I'll order one pronto.

... correct me If I'm wrong though.

cheers,

Petri

Petri,
The 3-transistor circuit does work, but it can be tempermental about the type of serial port used with it. Some laptops provide a limited voltage swing that isn't really RS-232. With a PropPlug/PropClip or USB2SER (different pin connections, but functionally the same), you won't have that issue and it'll work with a USB port.
