# watch-watch
watch-watch — вбудована система на ESP32-S3 для нагляду за п’ятьма силовими модулями на базі Raspberry Pi 5. ESP32-S3 керує DC/DC перетворювачами через сигнали `EN`, а також надає USB CLI інтерфейс для налаштування та діагностики без окремого UART.
## Основні можливості
- **Керування каналами живлення**: 5 незалежних ліній `EN` (GPIO 2, 4, 5, 18, 19), які можна увімкнути, вимкнути або перемкнути з коду чи CLI.
- **Послідовний автотест**: у `app_main` реалізовано базову логіку — канали вмикаються по черзі з інтервалом 4 с, що дозволяє перевірити всі DC/DC.
- **Нативний USB-CLI**: ESP32-S3 підключається до Raspberry Pi 5 по USB і стає CDC ACM пристроєм; командний інтерфейс дозволяє керувати каналами та дивитись стан у реальному часі.
- **Модульна архітектура**: окремі компоненти `dcdc_controller` і `usb_cdc_cli` спрощують розширення (телеметрія, автоматизація, протоколи зв’язку).
## Структура проєкту

│ ├── usb_cdc_cli.c/.h // TinyUSB CLI для Raspberry Pi 5

## GPIO-призначення каналів
| Канал | GPIO | Призначення |
|-------|------|-----------------------|
| 0 | 2 | Модуль живлення #1 |
| 1 | 4 | Модуль живлення #2 |
| 2 | 5 | Модуль живлення #3 |
| 3 | 18 | Модуль живлення #4 |
| 4 | 19 | Модуль живлення #5 |
> Піни можна змінити в `main/dcdc_controller.c`, масив `s_dcdc_gpio_map`.
## USB CDC CLI
Після підключення ESP32-S3 до Raspberry Pi 5 з’являється USB-пристрій (CDC ACM). У CLI доступні команди:
| Команда | Опис |
|------------------|------------------------------------|
| `help` | довідка по командам |
| `status` | поточний стан усіх каналів |
| `enable <n>` | увімкнути канал `n` (0..4) |
| `disable <n>` | вимкнути канал `n` |
| `toggle <n>` | перемкнути канал `n` |
CLI з’являється після того, як Raspberry Pi встановить DTR (наприклад, через `screen`, `picocom` або власний скрипт).
## Збірка та конфігурація
1. Встановіть ESP-IDF v5.5.1 (шлях `IDF_PATH` має вказувати на `/Users/tarassivas/esp/v5.5.1/esp-idf`).
2. Один раз виконайте `idf.py reconfigure`, щоб підвантажити залежності з `idf_component.yml`.
3. Переконайтеся, що в `sdkconfig` увімкнено:
- `CONFIG_TINYUSB_CDC_ENABLED=y`
- `CONFIG_TINYUSB_CDC_RX_BUFSIZE=128` (або інше значення за вашим сценарієм).
4. Зберіть проєкт: `idf.py build`, прошийте `idf.py flash`, переглядайте лог `idf.py monitor`.
## Подальший розвиток
1. Додати протокол обміну з Raspberry Pi (наприклад, командний набір через USB CLI або окреме IPC).
2. Включити зворотній зв’язок: вимір напруги/струму, датчики температури для кожного DC/DC.
3. Розширити CLI (макроси, сценарії, логування станів) та інтегрувати з продакшн-скриптами.

# Espressif's additions to TinyUSB
[![Component Registry](https://components.espressif.com/components/espressif/esp_tinyusb/badge.svg)](https://components.espressif.com/components/espressif/esp_tinyusb)
This component adds features to TinyUSB that help users with integrating TinyUSB with their ESP-IDF application.
It contains:
* Configuration of USB device and string descriptors
* USB Serial Device (CDC-ACM) with optional Virtual File System support
* Input and output streams through USB Serial Device. This feature is available only when Virtual File System support is enabled.
* Other USB classes (MIDI, MSC, HID…) support directly via TinyUSB
* VBUS monitoring for self-powered devices
* SPI Flash or sd-card access via MSC USB device Class.
## How to use?
This component is distributed via [IDF component manager](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html). Just add `idf_component.yml` file to your main component with the following content:
``` yaml

Hardware-related documentation could be found in [ESP-IDF Programming Guide](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-reference/peripherals/usb_device.html).
### Device Stack Structure
The Device Stack is built on top of TinyUSB and provides:
- Custom USB descriptor support
- Serial device (CDC-ACM) support
- Standard stream redirection through the serial device
- Storage media support (SPI-Flash and SD-Card) for USB MSC Class
- A dedicated task for TinyUSB servicing
### Configuration Options
Configure the Device Stack using `menuconfig`:
- TinyUSB log verbosity
- Device Stack task options
- Default device/string descriptor options
- Class-specific options
### Descriptor Configuration
Configure USB descriptors using the `tinyusb_config_t` structure:
- `device_descriptor`
- `string_descriptor`
- `configuration_descriptor` (full-speed)
- For high-speed devices: `fs_configuration_descriptor`, `hs_configuration_descriptor`, `qualifier_descriptor`
If any descriptor field is set to `NULL`, default descriptors (based on menuconfig) are used.
### Installation
Install the Device Stack by calling `tinyusb_driver_install` with a `tinyusb_config_t` structure. Members set to `0` or `NULL` use default values.
```c
const tinyusb_config_t partial_init = {
.device_descriptor = NULL,
.string_descriptor = NULL,
.external_phy = false,
#if (TUD_OPT_HIGH_SPEED)
.fs_configuration_descriptor = NULL,
.hs_configuration_descriptor = NULL,
.qualifier_descriptor = NULL,
#else
.configuration_descriptor = NULL,
#endif
};
```
### Self-Powered Device
Self-powered devices must monitor VBUS voltage. Use a GPIO pin with a voltage divider or comparator to detect VBUS state. Set `self_powered = true` and assign the VBUS monitor GPIO in `tinyusb_config_t`.
### USB Serial Device (CDC-ACM)
If enabled, initialize the USB Serial Device with `tusb_cdc_acm_init` and a `tinyusb_config_cdcacm_t` structure:
```c
const tinyusb_config_cdcacm_t acm_cfg = {
.usb_dev = TINYUSB_USBDEV_0,
.cdc_port = TINYUSB_CDC_ACM_0,
.rx_unread_buf_sz = 64,
.callback_rx = NULL,
.callback_rx_wanted_char = NULL,
.callback_line_state_changed = NULL,
.callback_line_coding_changed = NULL
};
tusb_cdc_acm_init(&acm_cfg);
```
Redirect standard I/O streams to USB with `esp_tusb_init_console` and revert with `esp_tusb_deinit_console`.
### USB Mass Storage Device (MSC)
If enabled, initialize storage media for MSC:
**SPI-Flash Example:**
```c
static esp_err_t storage_init_spiflash(wl_handle_t *wl_handle) {
// ... partition and mount logic ...
}
storage_init_spiflash(&wl_handle);
const tinyusb_msc_spiflash_config_t config_spi = {
.wl_handle = wl_handle
};
tinyusb_msc_storage_init_spiflash(&config_spi);
```
**SD-Card Example:**
```c
static esp_err_t storage_init_sdmmc(sdmmc_card_t **card) {
// ... SDMMC host and slot config ...
}
storage_init_sdmmc(&card);
const tinyusb_msc_sdmmc_config_t config_sdmmc = {
.card = card
};
tinyusb_msc_storage_init_sdmmc(&config_sdmmc);
```
### MSC Performance Optimization
- **Single-buffer approach:** Buffer size is set via `CONFIG_TINYUSB_MSC_BUFSIZE`.
- **Performance:** SD cards offer higher throughput than internal SPI flash due to architectural constraints.
**Performance Table (ESP32-S3):**
| FIFO Size | Read Speed | Write Speed |
|-----------|------------|-------------|
| 512 B | 0.566 MB/s | 0.236 MB/s |
| 8192 B | 0.925 MB/s | 0.928 MB/s |
**Performance Table (ESP32-P4):**
| FIFO Size | Read Speed | Write Speed |
|-----------|------------|-------------|
| 512 B | 1.174 MB/s | 0.238 MB/s |
| 8192 B | 4.744 MB/s | 2.157 MB/s |
| 32768 B | 5.998 MB/s | 4.485 MB/s |
**Performance Table (ESP32-S2, SPI Flash):**
| FIFO Size | Write Speed |
|-----------|-------------|
| 512 B | 5.59 KB/s |
| 8192 B | 21.54 KB/s |
**Note:** Internal SPI flash is for demonstration only; use SD cards or external flash for higher performance.

# CI target runner setup
To allow a Docker container, running on a CI target runner, to access USB devices connected to the CI target runner, some modifications must be made.
In our case, it's an `RPI` target runner.
The main idea comes from this response on [stackoverflow](https://stackoverflow.com/a/66427245/19840830). The same approach is also recommended in the official Docker [documentation](https://docs.docker.com/reference/cli/docker/container/run/#device-cgroup-rule)
### Following changes shall be made on a CI target runner
- [`UDEV rules`](#udev-rules)
- [`Docker tty script`](#docker-tty-script)
- [`Logging`](#logging)
- [`Running a docker container`](#running-a-docker-container)
- [`GitHub CI target runner setup`](#github-ci-target-runner-setup)
- [`GitLab CI target runner setup`](#gitlab-ci-target-runner-setup)
## UDEV rules
- This UDEV rule will trigger a `docker_tty.sh` script every time a USB device is connected, disconnected, or enumerated by the host machine (CI target runner)
- Location: `/etc/udev/rules.d/99-docker-tty.rules`
- `99-docker-tty.rules` file content:
``` sh
ACTION=="add", SUBSYSTEM=="tty", RUN+="/usr/local/bin/docker_tty.sh 'added' '%E{DEVNAME}' '%M' '%m'"
ACTION=="remove", SUBSYSTEM=="tty", RUN+="/usr/local/bin/docker_tty.sh 'removed' '%E{DEVNAME}' '%M' '%m'"
```
## Docker tty script
- This `.sh` script, triggered by the UDEV rule above, will propagate USB devices to a running Docker container.
- Location: `/usr/local/bin/docker_tty.sh`
- `docker_tty.sh` file content:
``` sh
#!/usr/bin/env bash
# Log the USB event with parameters
echo "USB event: $1 $2 $3 $4" >> /tmp/docker_tty.log
# Find a running Docker container (using the first one found)
docker_name=$(docker ps --format "{{.Names}}" | head -n 1)
# Check if a container was found
if [ ! -z "$docker_name" ]; then
if [ "$1" == "added" ]; then
docker exec -u 0 "$docker_name" mknod $2 c $3 $4
docker exec -u 0 "$docker_name" chmod -R 777 $2
echo "Adding $2 to Docker container $docker_name" >> /tmp/docker_tty.log
else
docker exec -u 0 "$docker_name" rm $2
echo "Removing $2 from Docker container $docker_name" >> /tmp/docker_tty.log
fi
else
echo "No running Docker containers found." >> /tmp/docker_tty.log
fi
```
### Making the script executable
Don't forget to make the created script executable:
``` sh
root@~$ chmod +x /usr/local/bin/docker_tty.sh
```
## Logging
- The `docker_tty.sh` script logs information about the USB devices it processes.
- Location: `/tmp/docker_tty.log`
- Example of a log from the `docker_tty.log` file, showing a flow of the `pytest_usb_device.py` test
```
USB event: added /dev/ttyACM0 166 0
USB event: added /dev/ttyACM1 166 1
Adding /dev/ttyACM0 to Docker container d5e5c774174b435b8befea864f8fcb7f_python311bookworm_6a975d
Adding /dev/ttyACM1 to Docker container d5e5c774174b435b8befea864f8fcb7f_python311bookworm_6a975d
USB event: removed /dev/ttyACM0 166 0
USB event: removed /dev/ttyACM1 166 1
```
## Running a docker container
### Check Major and Minor numbers of connected devices
Check the Major and Minor numbers assigned by the Linux kernel to devices that you want the Docker container to access.
In our case, we want to access `/dev/ttyUSB0`, `/dev/ttyACM0` and `/dev/ttyACM1`
`/dev/ttyUSB0`: Major 188, Minor 0
``` sh
peter@BrnoRPIG007:~ $ ls -l /dev/ttyUSB0
crw-rw-rw- 1 root dialout 188, 0 Nov 12 11:08 /dev/ttyUSB0
```
`/dev/ttyACM0` and `/dev/ttyACM1`: Major 166, Minor 0 (1)
``` sh
peter@BrnoRPIG007:~ $ ls -l /dev/ttyACM0
crw-rw---- 1 root dialout 166, 0 Nov 13 10:26 /dev/ttyACM0
peter@BrnoRPIG007:~ $ ls -l /dev/ttyACM1
crw-rw---- 1 root dialout 166, 1 Nov 13 10:26 /dev/ttyACM1
```
### Run a docker container
Run a Docker container with the following extra options:
``` sh
docker run --device-cgroup-rule='c 188:* rmw' --device-cgroup-rule='c 166:* rmw' --privileged ..
```
- `--device-cgroup-rule='c 188:* rmw'`: allow access to `ttyUSBx` (Major 188, all Minors)
- `--device-cgroup-rule='c 166:* rmw'`: allow access to `ttyACMx` (Major 166, all Minors)
## GitHub CI target runner setup
To apply these changes to a GitHub target runner a `.yml` file used to run a Docker container for pytest must be modified. The Docker container is then run with the following options:
``` yaml
container:
image: python:3.11-bookworm
options: --privileged --device-cgroup-rule="c 188:* rmw" --device-cgroup-rule="c 166:* rmw"
```
## GitLab CI target runner setup
To apply these changes to a GitLab runner the `config.toml` file located at `/etc/gitlab-runner/config.toml` on each GitLab target runner must be modified.
According to GitLab's [documentation](https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-runnersdocker-section) the `[runners.docker]` section of the `config.toml` file should include the `device_cgroup_rules` parameter:
``` toml
[runners.docker]
...
device_cgroup_rules = ["c 188:* rmw", "c 166:* rmw"]
```

* @brief TinyUSB Disconnect Detection test case
*
* This is specific artificial test for verifying the disconnection detection event.
* Normally, this event comes as a result of detaching USB device from the port and disappearing the VBUS voltage.
* In this test case, we use GPIO matrix and connect the signal to the ZERO or ONE constant inputs.
* Connection to constant ONE input emulates the attachment to the USB Host port (appearing VBUS).
* Connection to constant ZERO input emulates the detachment from the USB Host port (removing VBUS).
*
* Test logic:
* - Install TinyUSB Device stack without any class
* - In cycle:
* - Emulate the detachment, get the tud_umount_cb(), increase the dev_umounted value
* - Emulate the attachment, get the tud_mount_cb(), increase the dev_mounted value
* - Verify that dev_umounted == dev_mounted
* - Verify that dev_mounted == DEVICE_DETACH_TEST_ROUNDS, where DEVICE_DETACH_TEST_ROUNDS - amount of rounds
* - Uninstall TinyUSB Device stack
