Re: [Freetel-codec2] Thoughts

A lot boils down to the question. I think codec2 is well documented and list has always been helpful. I also think the last question asked about the UART was really a question about how to use the UART on the STM32 without breaking Codec2. The answer was use interrupt driven UART (or DMA UART)

You shouldn't have any problems doing that via DMA UART On Tue, Sep 6, 2016 at 9:52 AM, wrote: > I'm wondering if any body has managed to implement the serial USART in a > manner that does not interfere with the encode/decode process. > > Will be doing away with the switch menu

Re: [Freetel-codec2] options wanted-codec2 stmf4 code optimization question

My last project working with codec2, the code is coupled to kissfft. I don't believe its using any of the arm cmsis optimizations. Going to SHARC would put building outside realm of most users. C4FM and GSMK along with codec2 have been no problem for the F4 and F7 should have some headroom.

[Freetel-codec2] PICA/COMBO Star

I have been toying around with integrating CODEC2 within two of my P2 Star's . Its design is aging and I i'm interested if there is some interest in doing a modern version with CODEC2 built in and with STM32F4 as the GUI controller and replacing the AD DSP. KJ4WLC Shane

Re: [Freetel-codec2] VHF Frontend for VHF experimentation

I'd suggest looking at newer parts for the TX/RX switch, LNA section as well as considering using parts that reduce the part count. There are a lot of them on the board and generally parts back and front is really hard to assemble by hand. Maybe a reduction in part count if you used minicircits

I've settled on the stm32f4 as it has the MIPS and peripheral support. I also have had good luck with am3517 and the stellaris you mentioned as a full Linux setup. Ideally with the stm32f4 I hope to take the work David is doing with current codec2 and have a hardware module. Sent from my

Re: [Freetel-codec2] Freetel-codec2 Digest, Vol 36, Issue 36

The OMAP is not a great platform to use for the volumes of units that might make it into the ham world. I don't think the integrated DSP is needed when you have several hundred mhz arm and fpu anyways. At least from what I see and what I've been working on the idea is to come up with something

Re: [Freetel-codec2] Codec2 for uC or DSP

All of the Sitara lineup do have FPU but do not include the TI DSP. You will have to step up to OMAP platform for that. Any of the linux based offerings at this point have plenty of power to process a codec2 stream. How many of you are more interested, as I am, in getting this consistently
