+# DAPLink Bridge MicroPython Driver
+
+Low-level I2C bridge driver for the **STM32F103 DAPLink interface** on the STeaMi board.
+
+This driver handles all direct I2C communication with the bridge: device identification, status/error registers, busy polling, and persistent config zone access (1 KB internal flash).
+
+# I2C Address
+
+Default 7-bit I2C address: `0x3B`
+
+# Basic Usage
+
+```python
+from machine import I2C
+from daplink_bridge import DaplinkBridge
+
+i2c = I2C(1)
+bridge = DaplinkBridge(i2c)
+
+print("WHO_AM_I:", hex(bridge.device_id()))
+print("Busy:", bridge.busy())
+```
+
+# API
+
+## Initialization
+
+```python
+bridge = DaplinkBridge(i2c, address=0x3B)
+```
+
+Create a new DAPLink bridge instance.
+
+Parameters:
+
+* `i2c`: initialized MicroPython `I2C` bus
+* `address`: I2C address of the bridge, default is `0x3B`
+
+## Device identification
+
+### `device_id()`
+
+```python
+bridge.device_id()
+```
+
+Read the `WHO_AM_I` register. Expected value: `0x4C`.
+
+## Status
+
+### `busy()`
+
+```python
+bridge.busy()
+```
+
+Returns `True` if the bridge is currently busy, otherwise `False`.
+
+## Config zone
+
+The config zone is a **1 KB persistent storage area** in the STM32F103 internal flash. It is separate from the external flash file storage and survives `clear_flash()` operations.
+
+### `clear_config()`
+
+```python
+bridge.clear_config()
+```
+
+Erase the entire config zone. Raises `OSError` if the operation fails.
+
+### `write_config(data, offset=0)`
+
+```python
+bridge.write_config("board_rev=3", offset=0)
+bridge.write_config(b"\x01\x02\x03", offset=100)
+```
+
+Write data into the config zone at the given byte offset.
+
+Parameters:
+
+* `data`: `str` or `bytes`
+* `offset`: byte offset in the range `0` to `1023`
+
+Notes:
+
+* existing data outside the written range is preserved
+* raises `ValueError` if the write would go out of bounds
+* raises `OSError` if the bridge reports a write error
+
+### `read_config()`
+
+```python
+cfg = bridge.read_config()
+```
+
+Read back config zone content.
+
+Returns:
+
+* `bytes` up to the first `0xFF`
+* `b""` if the config zone is empty
+

+```
+
+* [`daplink_flash`](../daplink_flash/README.md) — high-level flash file operations
+* [`steami_config`](../steami_config/README.md) — persistent board configuration (JSON)
+
+# Notes
+
+* The bridge uses a `WHO_AM_I` value of `0x4C`.
+* The config zone (1 KB) is separate from the external flash file area.
+* All I2C operations go through private helpers (`_read_reg`, `_write_reg`, `_writeto`, `_readfrom`).
