Hi @chaosprint!
I will try to run this code in the afternoon (Rust starter for Daisy Seed - #26 by chaosprint) and report back!
Hi @chaosprint!
I will try to run this code in the afternoon (Rust starter for Daisy Seed - #26 by chaosprint) and report back!
I wrote a little example project. It has some abstractions for the Daisy Pod hardware built in, but don’t let them bother you.
Be careful to clone the example-sine-wave
branch!
Thanks for the work! The code looks super neat. I tried to compile it but still got no sound.
firstly, I need to remove the "sdmmc", "sdmmc-fatfs"
features from libdaisy-rust
and all the SD card related code in your template as it causes errors during compiling on my machine.
my rustc --version
:
rustc 1.66.0-nightly (a24a020e6 2022-10-18)
since I don’t have ST-LINK, I did
cargo objcopy --release -- -O binary a.bin
then:
dfu-util -a 0 -s 0x08000000 -D a.bin
everything looks fine but just no sound.
from cargo readobj --bin daisy-blank -- --file-headers

Could you please tell me your Rust version and how you flash the board?
No need to thank! I would have set up such a repo in the future anyway. Your issue gave me the motivation to do it right now. (It’s from a bigger project I’m working on, from which I stripped everything but the skeleton that is the Daisy Pod hardware initialization.)
You mentioned before that the SD card driver caused you issues. Most interesting. Honestly, I have no explanation for it.
When I do cargo readobj --bin daisy-blank -- --file-headers
, the output looks identical. The only difference is that the start of the section headers is slightly shifted, which should be of no concerns.
Start of section headers: 1677700 (bytes into file)
For the sake of completeness, my rust version. Also, I use an ST-Link with probe.rs
over JTAG to flash the Seed. However, since you can successfully flash your device, I wouldn’t stress too much about not having a ST-Link.
$ rustc --version
rustc 1.64.0 (a55dd71d5 2022-09-19)
For me, everything looks like it should work in your case. I will try to pull out the Seed from the Pod and see if it is related to the Seed not being in there at all. If not, I really don’t have any explanation, other than that you might have an older revision…
Confirmed working with the Seed sitting naked on the table.
Yeah! I get it working now with the same Rust version as yours. But I guess it’s good to also look into why the updated Rust version causes an issue as it may become stable soon anyway.
Nice, glad to hear!
