Hello,

When I try to flash my daisy board with an example (for instance blinky), the program does not start.

It works if I revert to stm32h7xx-hal 0.13.1 with the following patch:

--- a/Cargo.toml
+++ b/Cargo.toml

 panic-rtt-target = { version = "0.1.2", features = ["cortex-m"], optional = true }
 lazy_static = { version = "1.4.0", features = ["spin_no_std"], optional = true  }

The issue seems to happen quite early at initialization: I tried to reduce the system::System::init() method to a minimal code that blinks a led, and it does not blink with 0.14.0 (while it blinks with 0.13.1).

I use rust 1.70.

Is anyone else seeing the same issue?
please @dobrite, can you confirm it's working on your side?

Hi,
I forked your library and updated the audio.rs file to support the new codec WM8731 of the Daisy Seed rev 1.1.
Unfortunately, I have some audio distortions when passing audio through. At 1 kHz, I can see on the oscilloscope that the wave has artifacts.

As stated here

In case you want to take a look:
https://github.com/backtail/libdaisy-rust

Implement QSPI for flash memory access.

Implement working DMA. Enable dcache.

it has been released for a while..

@x37v has a WIP

see http://blog.reverberate.ca/post/zero-latency-convolution/

This would be my learning project, figure other might like it too, but you could get it working much fast than me. It's useful for reverb & cabinet/mic simulation via impulse responses. I assume it's what all the impulse response (IR) guitar pedals are doing.

After DMA lands write working looper demo.

I just wanted to query the status of this project. I would really like to start experimenting with rust on the daisy hardware platform, but it looks like it still needs a bit of work to make it work flawlessly. And as a total noob in rust and embedded rust I am quite sure to be currently completely useless as a contributor :)

How far do you think we are from that goal ?
What do you see as the biggest chalenges ?

After DMA lands have working delay example with delay length and echo controls. Other controls?

When creating a new libdaisy-rust project you'll need to copy or create your own memory.x and .cargo/config files to tell the compiler how to build the binary image.

blinky works fine. passthru doesn't pass audio through, but just produces a tone. I'm a total beginner with embedded programming, but it sounds like it produced one buffer of data and it's just looping that.

I don't know how to receive the log data, so I don't know if something is going wrong internally.

I don't know the revision of the Daisy Seed, but I get this from dfu-utils:

Found DFU: [0483:df11] ver=0200, devnum=1, cfg=1, intf=0, path="1-1", alt=1, name="@Option Bytes   /0x5200201C/01*128 e", serial="200364500000"
Found DFU: [0483:df11] ver=0200, devnum=1, cfg=1, intf=0, path="1-1", alt=0, name="@Internal Flash   /0x08000000/16*128Kg", serial="200364500000"

if not.. remove the _bss from the name

After running for a minute or so the sound stops working in the volume example.

Need to update to work with stm32h7xx-hal 0.9.0.

Docs.rs compiler needs correct arguments.
