Hey,
Trying to set up a HiFiBerry DSP. Managed to get everything installed and running on the Pi4, and a connection to SigmaStudio to install dacdsp-v11 project/profile.
However trying to create a basic interface using DSPToolkit - it appears I can correctly set the MasterVolume fader:
eg: (0.0dB) dsptoolkit write-mem 0x2F 0x01000000
(Where the exported Sigma Header lists:
#define MOD_MASTERVOL_ALG0_TARGET_ADDR 47 = 0x2F)
But when I read the same register back, I get a different value:
dsptoolkit read-hex 0x2F
00 80 00 00
The data value returned changes when the fader is adjusted via the dsptoolkit, or via the SigmaStudio GUI, but never returns the expected value.
I cannot see any obvious relationship between the 'expected' and 'returned' numbers (they're not obviously byte-swapped, bit-shifted, or bit-reversed).
Have I gotten something obvious wrong, or is this maybe a bug in the SPI readback process within the DSPToolkit??
Expected: 0x00CB5918 Readback: 00 72 96 86
Expected: 0x0000068E Readback: 00 00 01 63
Expected: 0x00028F5C Readback: 00 00 63 97
Many thanks

HiFiBerry team Ok, I see the problem. We didn't create a Pypi package for quite a long time. Therefore, the latest release is not yet on pypi. You can either download and install directly from Github:
https://github.com/hifiberry/hifiberry-dsp
Or wait a bit until we packages and released it to pypi. -
HiFiBerry team If you already clones it, just change to the directory and run
pip install --upgrade . -
Keith Ovenden Problem resolved.
Just a quick note for anyone who ever has the same problem. I solved the issue by getting a fresh RaspbianOS install on my Pi4 then NOT installing the BEOCreate toolkit, and instead:sudo pip3 install --upgrade hifiberrydsp bash <(curl https://raw.githubusercontent.com/hifiberry/hifiberry-dsp/master/install-dsptoolkit) git clone github.com/hifiberry/hifiberry-dsp cd /hifiberry-dsp sudo pip install --upgrade . bash <(curl https://raw.githubusercontent.com/hifiberry/hifiberry-dsp/master/install-dsptoolkit)
reboot Test TCP-=IP Server is running: sudo systemctl status sigmatcp Should say 'ACTIVE'I'm guessing I probably didn't actually need the original pip3 install, and could have just checked out and installed the GitHub HifiBerry version directly. But that's the process that worked for me.
I now have the ability to connect via SigmaStudio, AND can control parameters via DSPToolkit - with 'set' and 'get' commands working as expected.
Thanks for the assistance. Great product :o) -
HiFiBerry team Interesting. I'm not sure why this happens. I haven't seen this before. Try using decimal numbers instead of hexadecimal. Maybe it's a bug in parsing the hex numbers.

Keith Ovenden I believe the write is working correctly - if I set the Fader to -6dB via Sigma, and send a value of 0x00800000 via DSPToolkit - I get the same level of audio at my output (although I haven't hooked up a test sinewave wav and measured the actual gain change on a scope).
So it's 99% likely to be the readback where the fault occurs.
Setting:
dsptoolkit write-mem 47 16777216
returns:
dsptoolkit read-hex 47: 00 80 00 00
dsptoolkit read-int 47: 8388608
dsptoolkit read-dec 47: 0.50000000
I've tried rebooting the Pi, and restarting beocreate-tcp, but always see the same behaviour.
Any pointers would be much appreciated. -
HiFiBerry team Just tested here:
# dsptoolkit write-mem 31 0x01000000
# dsptoolkit read-hex 31
01 00 00 00Seems to work fine. Are you using the latest version?
-
Keith Ovenden Thanks, I've tried a few things but still no joy with this board.
I believe im on latest version of the dsptoolkit:sudo pip3 install --upgrade hifiberrydsp
and I've run:
bash <(curl https://raw.githubusercontent.com/hifiberry/hifiberry-dsp/master/install-dsptoolkit)

Would the version of beocreate-tcp matter? (for a couple of reasons I've got the 'beocreate1' branch installed rather than 'beocreate2' -
Keith Ovenden Thanks. Glad you can understand what might be happening.
Sorry, I'm still relatively new to Linux - so apologies for the dumb question.... I've got a git-clone of the latest hifiberry-dsp repo.
How do I install the DSPtoolkit from there, rather than doing 'sudo pip3 install --upgrade hifiberrydsp' (which is obviously going to Pypi to look for a new version).
