Re: [softrock40] peaberry theory of operation?
- Hang on Rick,
I longed to see the back of vacuum tubes forever having got a number of shocks from them.
I have built many transistor and FET PA's over the decades but never got up the courage to use that 813 which is still in a box in the loft since I got it in July 1966.
73 ... Sid.

Sorry, but I am not willing to spend the time to learn PSoC Creator just so I can understand in general how the Peaberry works.

Rick,PSoC Creator is very visual with all the top level design done in schematic capture. What you're looking for is in the source code. Maybe you're not a Windows user so I've attached a picture of the top design.73 David AE9RBOn Wed, Oct 24, 2012 at 8:21 PM, Rick Simpson <goatguy101@...> wrote:
David,I had seen the posts here on the Peaberry but did not realize it used a PSoC. I examined the Peaberry website and wonder if anyone has generated a description of how the transciever works -- an overall flow diagram and description of what parts of the PSoC are used in what way to implement the necessary SDR functions.Rick----- Original Message -----From: David TurnbullSent: Wednesday, October 24, 2012 10:30 PMSubject: Re: [softrock40] Re: Interesting SDR project funded by DARPA
Rick and Sid,My Peaberry SDR transceiver kit uses the Cypress PSoC chip you are talking about. There are lots of models, including some with a Cortex M3, but I'm using the smallest 8051 version that supports USB.Source code and schematic here:73 David AE9RB
