[lsm6ds] Restructure component with _base, _i2c, _spi pattern
Major restructure to follow ESPHome conventions for multi-interface components: Component Structure Changes: - Renamed lsm6ds/ to lsm6ds_base/ to follow _base naming convention - Created lsm6ds_i2c/ for I2C interface implementation - Created lsm6ds_spi/ for SPI interface implementation - Both interfaces use AUTO_LOAD to automatically include base component - Updated C++ namespaces to match component folder names (lsm6ds_base, lsm6ds_i2c, lsm6ds_spi) Features: - Support for LSM6DSOX, LSM6DS3TR-C, LSM6DSO32 variants - Full 3-axis accelerometer and gyroscope support - Temperature sensor support - Configurable ranges: Accel (2G-16G), Gyro (125-2000 DPS) - Configurable output data rate (12.5Hz - 6.66kHz) - Two usage patterns: all-in-one and hub+sensor platform Implementation Details: - Base component (lsm6ds_base) contains shared code and abstract LSM6DSComponent class - I2C variant implements LSM6DSI2CDevice with I2C read/write methods - SPI variant implements LSM6DSSPIDevice with SPI read/write methods (MSB-based protocol) - Both variants support optional sensor.py for hub+sensor pattern - Added README_EXAMPLE.md files with usage examples for both interfaces - Added component test files for validation Documentation: - Added COMPONENT_STRUCTURE.md explaining architecture and usage patterns - Included example configurations for both I2C and SPI - Documented all configuration options and sensor variants

# LSM6DS Component Structure
|
||||
|
||||
This document describes the organization of the LSM6DS family IMU sensor components for ESPHome.
|
||||
|
||||
## Folder Structure

||||

||||

|

```
|
||||
|
||||
## Component Relationships
|
||||
|
||||
### Auto-Loading Pattern
|
||||
Both `lsm6ds_i2c` and `lsm6ds_spi` use `AUTO_LOAD = ["lsm6ds_base"]` to automatically include the base component when either interface variant is used. Users only need to configure `lsm6ds_i2c` or `lsm6ds_spi` directly.
|
||||
|
||||
### Dependencies
|
||||
- **lsm6ds_base**: No dependencies (standalone base)
|
||||
- **lsm6ds_i2c**: Depends on `i2c`, auto-loads `lsm6ds_base`
|
||||
- **lsm6ds_spi**: Depends on `spi`, auto-loads `lsm6ds_base`
|
||||
|
||||
### Class Hierarchy
|
||||
|
||||
```
|
||||
C++ Class Structure:
|
||||
|
||||
LSM6DSComponent (abstract base class)
|
||||
↑
|
||||
├── LSM6DSI2CDevice : public LSM6DSComponent, public i2c::I2CDevice
|
||||
│ └── Implements: read_register() and write_register() via I2C
|
||||
│
|
||||
└── LSM6DSSPIDevice : public LSM6DSComponent, public spi::SPIDevice
|
||||
└── Implements: read_register() and write_register() via SPI
|
||||
```
|
||||
|
||||
## Usage Patterns
|
||||
|
||||
### Pattern 1: All-in-One (Recommended for most users)
|
||||
Configure the sensor with all outputs directly in the component block:
|
||||
|
||||
```yaml
|
||||
lsm6ds_i2c: # or lsm6ds_spi
|
||||
id: imu_sensor
|
||||
# ... interface config (I2C address or SPI CS pin)
|
||||
accel_range: 4G
|
||||
gyro_range: 500DPS
|
||||
accel_odr: 104HZ
|
||||
gyro_odr: 104HZ
|
||||
accel_x:
|
||||
name: "Accel X"
|
||||
gyro_x:
|
||||
name: "Gyro X"
|
||||
# ... other sensors
|
||||
```
|
||||
|
||||
### Pattern 2: Hub + Sensor Platform
|
||||
Configure the hub separately, then add sensors under the sensor platform:
|
||||
|
||||
```yaml
|
||||
lsm6ds_i2c: # or lsm6ds_spi
|
||||
id: imu_hub
|
||||
# ... interface config
|
||||
accel_range: 4G
|
||||
gyro_range: 500DPS
|
||||
|
||||
sensor:
|
||||
- platform: lsm6ds_i2c # or lsm6ds_spi
|
||||
lsm6ds_id: imu_hub
|
||||
accel_x:
|
||||
name: "Accel X"
|
||||
# ... other sensors
|
||||
```
|
||||
|
||||
## Supported Sensors
|
||||
|
||||
- **LSM6DSOX**: WHO_AM_I = 0x6C
|
||||
- **LSM6DS3TR-C**: WHO_AM_I = 0x6A
|
||||
- **LSM6DSO32**: WHO_AM_I = 0x69
|
||||
|
||||
All variants support:
|
||||
- 3-axis accelerometer (±2G, ±4G, ±8G, ±16G)
|
||||
- 3-axis gyroscope (±125, ±250, ±500, ±1000, ±2000 DPS)
|
||||
- Temperature sensor
|
||||
- Configurable output data rate (12.5Hz to 6.66kHz)
|
||||
- Both I2C and SPI interfaces
|
||||
|
||||
## Code Generation Flow
|
||||
|
||||
1. User configures `lsm6ds_i2c` or `lsm6ds_spi` in YAML
|
||||
2. ESPHome auto-loads `lsm6ds_base` component
|
||||
3. Python `__init__.py` validates config and generates C++ code
|
||||
4. `register_lsm6ds()` function:
|
||||
- Registers component with ESPHome
|
||||
- Sets range and ODR configuration
|
||||
- Creates sensor entities for requested outputs
|
||||
5. C++ `setup()` method:
|
||||
- Detects sensor variant via WHO_AM_I
|
||||
- Configures sensor registers
|
||||
- Calculates sensitivity values
|
||||
6. C++ `update()` method:
|
||||
- Reads sensor data
|
||||
- Publishes to sensor entities
|
||||
|
||||
## CODEOWNERS
|
||||
|
||||
All three components list `@NonaSuomy` as the code owner for maintenance and review.

# LSM6DS I2C Example Configuration
|
||||
|
||||
This component supports LSM6DS family IMU sensors (accelerometer + gyroscope) via I2C interface.
|
||||
|
||||
## Supported Sensors
|
||||
- LSM6DSOX (WHO_AM_I: 0x6C, I2C address: 0x6A or 0x6B)
|
||||
- LSM6DS3TR-C (WHO_AM_I: 0x6A, I2C address: 0x6A or 0x6B)
|
||||
- LSM6DSO32 (WHO_AM_I: 0x69, I2C address: 0x6A or 0x6B)
|
||||
|
||||
## Example 1: All-in-one Pattern
|
||||
|
||||
Configure the sensor with all outputs in the component block:
|
||||
|
||||
```yaml
|
||||
i2c:
|
||||
- id: i2c_bus
|
||||
sda: GPIO21
|
||||
scl: GPIO22
|
||||
scan: true
|
||||
|
||||
lsm6ds_i2c:
|
||||
id: imu_sensor
|
||||
i2c_id: i2c_bus
|
||||
address: 0x6B
|
||||
accel_range: 4G
|
||||
gyro_range: 500DPS
|
||||
accel_odr: 104HZ
|
||||
gyro_odr: 104HZ
|
||||
update_interval: 50ms
|
||||
accel_x:
|
||||
name: "Accel X"
|
||||
accel_y:
|
||||
name: "Accel Y"
|
||||
accel_z:
|
||||
name: "Accel Z"
|
||||
gyro_x:
|
||||
name: "Gyro X"
|
||||
gyro_y:
|
||||
name: "Gyro Y"
|
||||
gyro_z:
|
||||
name: "Gyro Z"
|
||||
temperature:
|
||||
name: "IMU Temperature"
|
||||
```
|
||||
|
||||
## Example 2: Hub + Sensor Platform Pattern
|
||||
|
||||
Configure the hub separately, then add sensor outputs under the sensor platform:
|
||||
|
||||
```yaml
|
||||
i2c:
|
||||
- id: i2c_bus
|
||||
sda: GPIO21
|
||||
scl: GPIO22
|
||||
scan: true
|
||||
|
||||
lsm6ds_i2c:
|
||||
id: imu_hub
|
||||
i2c_id: i2c_bus
|
||||
address: 0x6B
|
||||
accel_range: 4G
|
||||
gyro_range: 500DPS
|
||||
accel_odr: 104HZ
|
||||
gyro_odr: 104HZ
|
||||
update_interval: 50ms
|
||||
|
||||
sensor:
|
||||
- platform: lsm6ds_i2c
|
||||
lsm6ds_id: imu_hub
|
||||
accel_x:
|
||||
name: "Accel X"
|
||||
accel_y:
|
||||
name: "Accel Y"
|
||||
accel_z:
|
||||
name: "Accel Z"
|
||||
gyro_x:
|
||||
name: "Gyro X"
|
||||
gyro_y:
|
||||
name: "Gyro Y"
|
||||
gyro_z:
|
||||
name: "Gyro Z"
|
||||
temperature:
|
||||
name: "IMU Temperature"
|
||||
```
|
||||
|
||||
## Configuration Options
|
||||
|
||||
### I2C Address
|
||||
- `0x6A` (default, SDO/SA0 pin LOW)
|
||||
- `0x6B` (SDO/SA0 pin HIGH)
|
||||
|
||||
### Accelerometer Range
|
||||
- `2G` (default)
|
||||
- `4G`
|
||||
- `8G`
|
||||
- `16G`
|
||||
|
||||
### Gyroscope Range
|
||||
- `125DPS`
|
||||
- `250DPS` (default)
|
||||
- `500DPS`
|
||||
- `1000DPS`
|
||||
- `2000DPS`
|
||||
|
||||
### Output Data Rate (ODR)
|
||||
- `12.5HZ`
|
||||
- `26HZ`
|
||||
- `52HZ`
|
||||
- `104HZ` (default)
|
||||
- `208HZ`
|
||||
- `416HZ`
|
||||
- `833HZ`
|
||||
- `1660HZ`
|
||||
- `3330HZ`
|
||||
- `6660HZ`
|
||||
|
||||
## I2C Configuration
|
||||
|
||||
The LSM6DS I2C implementation uses standard I2C communication:
|
||||
- **Speed**: Supports up to 400 kHz (Fast mode)
|
||||
- **7-bit addressing**: 0x6A or 0x6B depending on SDO/SA0 pin state
|
||||
- **Auto-increment**: Multi-byte reads automatically increment register address
|
||||
|
||||
The component handles the I2C protocol automatically.

- **MSB first**
|
||||
- **Read bit**: MSB set to 1 (reg | 0x80)
