`audio` example produces no sound, or produces a loud tone.

[GregoryTravis]

With this command:

make flash WHAT=audio BOARD=seed_1_1

I get no audio output at all.

With this:

make flash WHAT=audio BOARD=seed

I get a loud 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 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"

Hey @GregoryTravis, thanks for reporting this.

If you look at your daisy, what is written on top? Is there Seed or Seed 1.1? If you have bought it recently, chances are it is seed_1_1.

The audio example is not producing any tone on its own, it only passes through the input audio and switches left input to the right output and vice versa. In other word - you have to plug in some sound input to get an output. Could you try that?

Let me know if you would have any other issues. Hope you'll have fun with Rust and Daisy!

[GregoryTravis]

It looks like 1.2:

I had audio coming in the input port, but I didn't hear it at all, only the loud tone.

[phoracek]

Oh interesting. I was not aware that there is a new Daisy release. Would you mind sharing a closer photo of the chip thats on the far side of the photo above? I would like to see what Codec it uses. I suspect it is the same one as used on the Daisy Patch SM. If that's the case, I could add support for that - if you would be willing to test it.

[GregoryTravis]

I would be happy to test it.

[phoracek]

Cool! I'll try to get a patch ready for tomorrow.

@GregoryTravis when you find some time, please try this with feature flag seed_1_2.

# Cargo.toml
[dependencies]
daisy = { git = "https://github.com/zlosynth/daisy.git", branch = "seed_1_2" }

[GregoryTravis]

I'm working directly in the zlosynth/daisy repo, on branch seed_1_2 -- how do I set the feature flag in this case?

I'm getting:

error: target board must be selected using a feature: "seed_1_2" | "seed_1_1" | "seed" | "patch_sm"

You have to specify it when flashing the example:

make flash WHAT=audio BOARD=seed_1_2

[GregoryTravis]

I can't build the project on branch seed_1_2. I get the errors shown above.

[phoracek]

Could you share the commands you run to build it?

[GregoryTravis]

I apologize -- I forgot that you don't need to build it first. I flashed it with make flash WHAT=audio BOARD=seed_1_2, but I'm still getting the loud tone.

[phoracek]

Darn. I'll check with the Daisy Discord. Speaking of - I found a mention of a libdaisy-rust that is patched with Daisy Seed 2 DFM support. I suspect that it may also cover Seed 1.2. Give it a shot https://github.com/CorvusPrudens/libdaisy-rust, so I don't block you with my troubleshooting. Plus, knowing that whatever is done on that fork works (or does not) would make my work simpler too. I recommend visiting #rust room on the Discord channel https://discord.com/channels/1037767234803740694/1039305128886403072

[GregoryTravis]

Thanks for the tip, I'll try it! I'm actually in that discord, I saw you asking about it :)

[GregoryTravis]

Forgive me, I'm a rust beginner. Below is what I got with that fork, running cargo objcopy --example passthru --release -- -O binary passthru.bin. I don't quite understand the results; it mentions 2 errors, but there were no errors.

   Compiling libdaisy v0.1.0 (/Users/gmt/pedal-stuff/rust-libraries/patched-libdaisy-rust/libdaisy-rust)
error: could not compile `libdaisy` (example "passthru") due to 2 previous errors

@GregoryTravis it is hit or miss, but I made some changes to the branch (commit fdca39e) and maybe (big maybe) it will work now. If you get to try it, please let me know if it is any better now.

Edit: If it would not work after this, I suggest trying this too:

        #[cfg(feature = "seed_1_2")]
        let transfer_config = TransferConfig {
            tx_channel: Channel::A,
            rx_channel: Channel::B,
            tx_sync: Sync::Slave,
            rx_sync: Sync::Master,
        };

[GregoryTravis]

The tone is gone! But I'm still not getting audio through. I tried it unchanged and also with the transfer_config change.

[phoracek]

Mmm, too bad. While trying to get to the bottom of this, here is another idea - could you try flashing the original version that produced the beep 6ace8b2? And once you flash it, try restarting the module by clicking the buttons or just power off-on. Sometimes the firmware gets stuck for me after flashing over USB, but after restart it works. If that won't help, try the other combinations of A/B Slave/Master.

[GregoryTravis]

I restarted the model after flashing using the two buttons, which made the beep go away. I tried all four combinations; only the original one produced a beep:

            tx_channel: Channel::A,
            rx_channel: Channel::B,
            tx_sync: Sync::Master,
            rx_sync: Sync::Slave,

Is there another way to do a power-on, other than the white buttons? If there is, I didn't try it.

I assume that the two buttons a full reset -- if I am running an LED-blinking patch on it, the blinking stops when I reset with the two buttons.

[GregoryTravis]

This is odd; only this one produces a blinking LED:

            tx_channel: Channel::B,
            rx_channel: Channel::A,
            tx_sync: Sync::Slave,
            rx_sync: Sync::Master,

I have finally got Seed 1.2. With 942ae2e it seems to be working. The only issue is that the output is very noisy. While that is not seen much with loud signal, this is what it looks like with 0.7 VPP.

Seed 1.0:

Seed 1.2:

Even with 3 VPP it looks pretty rugged on 1.2:

And it is not any better with the reference bypass example:

[phoracek]

I checked with Daisy Discord and it seems that this is expected and should not be too audible. It can be further countered using a low-pass filter. With the support for Seed 1.2 introduced to the create, I'm closing this issue.
