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?

Implement QSPI for flash memory access.

Implement working DMA. Enable dcache.

Need to update to work with stm32h7xx-hal 0.9.0.

Docs.rs compiler needs correct arguments.

it has been released for a while..

@x37v has a WIP

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 ?

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.

After DMA lands write working looper demo.

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

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.

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:

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

if not.. remove the _bss from the name

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:
