just a quick look at the board powered on and in debugging mode.
the bluetooth module is plugged in and working.
I'm nearly done porting over the basic mixer code for the DSP ADAU1467 from the old ADAU1446 and i'm
starting to use safeload code loaded to RAM for the DSP coefficient on the fly changes.
I think I will make a digital AES3 IO board for bus B and just have 16 channels of differntial analouge IO using Bus A.
I sort of regret not putting on a 1" oled screen on there just so I can print some basic status info although its not really essential.
Would have looked cool and there so cheap ! maybe its for the best , could be just a waste of precious power since it will
eventually be a battery device !
The Debugger might stay on there for another revision. It might be useful for just updating firmware if nothing else.
Its just an STM32F10xx . Obviously I could'nt re-sell the board with the stm debugger software installed , but maybe I could
leave that to the end user :) I think my worst error on this board revision was to not connect the stm32f10xx to breakouts for
programming. For some reason I though I could just program it through the JTAG header connected to the STM32F769xx !!
Obviously that was not the case , so I ended up getting some really thin gauge wire and tacking onto stupid places to flash the
debugger firmware. I sought I'll do that again on this board !
these people are doing some nice Analouge Devices DSP boards but like me i'm not including the AD sigmastudio debugger on the main PCB :) http://www.freedsp.cc/
The next board will have a nice TC2030-IDC 6-Pin footprint on it as the massive 20pin header for JTAG /SWD is a gross waste of space :)
I ordered one from here
unfortunately I had to pay a massive postage fee to get one to Japan , they seam to have run out here !
Anyway , it will save a ton of board space in the long run..
