Now, maybe this is just because I was a full time Zune user until now, but I wish the Tangara had:

- No repeat
- Repeat album/playlist
- Repeat 1 song

that worked with selecting individual tracks but still repeating the whole album.

I recently forked the Tangara code on codeberg to work on a couple things. Namely, I want to add a view on the device for Genres -> Artists -> Albums -> Songs. Looking at how the other similar views / DB navigation trees were setup, I assumed this would be pretty straightforward. However, my attempt has appeared to replicate instead the "Tracks by Genre" view! I tried a couple different ideas, but all produced the same behaviour.

I am not asking for you kind folks to debug the feature for me of course, but I am asking for where I should start looking in order to figure this out. There's a lot of code in this project! I wonder if there is a limit on navigation depth because of the way the DB is done? I am not sure...

The diff is here in case you are curious: https://codeberg.org/homoelectromagnetic...05686a60f8

Thanks all for your time!]]>

So far I implemented a very simple driver for the PCA8575 GPIO expander and used it to mount the SD card.

Any help would be appreciated! Installing the toolchain is easy, just follow Espressif's documentation to use esptool, which is like rustup for Espressif's fork of Rust.]]> https://codeberg.org/Be.ing/tangarust

Currently, on Tangara, if I leave the menu, I have to scroll back to where I was and it kind of makes me hesitant to browse and look around the player whilst listening to look at another submenu (say Genres) because if I return, I will have to scroll all the way down to get back to where I was.

Is having Tangara remember where you were in a submenu (like which track you had highlighted on an album, or which album of an artist, or which artist in Albums by Artist) something possible?

Thank you Smile]]>

As I currently understand things (not to be pedantic, but), Tangara Companion isn't directly developed by Cool Tech Zone project but by Hailey.

I bring this up for the long term future, as this distinction might confuse users who aren't usually in the usual Crowd Supply audience, as I might suggest Tangara to some other non-technical friends down the road.]]>

I'm sure this is something I can probably train myself to stop doing, but it also seems like this could be fixed in software. Something like a small delay between the last time a scrolling gesture was captured and that button being active perhaps? I'm curious if there are other ideas around this.]]>

I just got my tangara today Smile I really enjoy it so far but something that I am having trouble with is the long press function on the controls. I know that in the API, here, there is reference to controls.scheme, but I cannot seem to find that in the firmware tree to look at. I did find it on input_touch_wheel.cpp but I do not know if that is the right place to make changes.

I am really new to hacking anything, but I would really like to learn. One of the other things I'd like to do is change what the menu shows and I seem to be missing quite a few tracks, too. But I will make separate threads for those.

I just wanted to know if anyone could point me in the direction of;
  • How to change the control scheme
  • How to build(?) the firmware and then flash it on to my tangara

I think with the second point, it'd be kind of cool to have a pinned guide so other people who are new to this have a place to start.
