Is there already code that allows us to interact with the sd card or do we have to write it ourselves? |
|
I will like to take this one today to start working on storage as discussed :) |

…#502 #570 (#590) Splitting PR into a number of PRs, these changes required to get SD card and other hardware changes live and verified. Helps fix #502 #570 Changelog: * Fixed debug mode in project, debug works using native UART via USB * Added native log collector and log levels info, debug, warning, error * Added support for automated cmake config to support overlay files for device specific config for SD card * Added support for various device configurations in build config (FYI Adafruit module pins needs to be updated) * Better build documentation in `README.rst` * Improved boot sequence with booting all LEDs for testing and verification of device * Improved errors using LEDs to show what has failed, allowing for better customer support * VScode default extensions added and whitelisted in gitignore _Screenshot with UART logging (one working and one with simulated failures), and working build showing._ <img width="1799" alt="image" src="https://github.com/user-attachments/assets/99435755-9e32-4af4-aa0e-5bdd71885b98"> _Screenshot showing how build settings is auto-detected_ <img width="1366" alt="Screenshot 2024-08-11 at 11 42 32 pm" src="https://github.com/user-attachments/assets/49093e3b-2952-418a-82a5-d1e714cd41a9"> _Screenshot showing multiple deployment types depending on device_ <img width="720" alt="image" src="https://github.com/user-attachments/assets/f1dbc938-4e1d-4bee-9e6c-e5f31b072eb7">

#570 How to test: 1. Flash the uf2 file in the file storage_build. Hopefully you have the sd card pins configured as in the hardware schematic. Please make sure your sd card is already in the slot when it turns on, otherwise it will not work. 2. To ensure this works, sever the connection from the friend app. After the flashing sequence the device should turn red, but it should start recording to the sd card. 3. Use the python file "discover_devices.py" to find your device id. Then in the file "get_info_list.py", place your id on line 12, labeled device_id. Then run the file. The expected result is a list of numbers. Numbers from left to right are the oldest created files to the newest created files. The amount of numbers is the amount of files. For examples, one list of numbers could be [1000 10000 20000] where 1000 is the oldest file with 1000 bytes, 10000 is the second file with 10000 bytes, and 20000 is the newest file with 20000 bytes. 5.On line 13 of the file "get_audio_file.py", place your device id. The run the file. You should be presented with a large wall of numbers indicating opus packets. This file downloads all available files on the device. Each packet is 103 bytes long. The first three bytes are the same as if mic data was sent. The fourth byte is how many numbers are in the packet. Let's call it x. The next x bytes are the opus-encoded numbers. The rest of the packet is filled with zeroes. All of this is stored into the file "my_file.txt" 6. Finally, "decode_audio.py" attempts to decode the file. My opus files are corrupted so I can't verify, but each packet at least appears to be preserved. You are welcome to try. For now, you can open the serial port to see a wall of text showing the data is being streamed into the sd card. If you want to create another file on the sd card, simply reset the device and new data will pour into a separate file. You can always check with "get_info_list.py." The mic should work as normal if you connect it to the friend app. Any blue tooth connection stops writes to the sd card. Any disconnection should resume data transfer to the sd card. You can always check with get_info_list.

Is your feature request related to a problem? Please describe.
I want my Friend to be able to store my recordings even when the device is disconnected.
Describe the solution you'd like
This ticket should be mainly on the firmware side, but ideally you create in capture/page.dart a button to view the list of of offline recording files available + an option to start receiving them and print them in the console.
