+CH347 Module
+------------
+
+The `ch347` module provides functions for interacting with the CH347 USB-UART/SPI/I2C/JTAG bridge.
+
+Initialization:
+----------------
+
+- Use `ch347.init()` to initialize the CH347 device.
+
+Configuration:
+--------------
+
+- Use `ch347.set_spi_config(clock: int, mode: int)` to configure the SPI parameters.
+
+SPI Communication:
+------------------
+
+- Use `ch347.spi_write(device_index: int, chip_select: int, write_data: bytes, write_step: int)`
+  to write data to the SPI bus.
+
+- Use `ch347.spi_read(device_index: int, chip_select: int, write_data: bytes, read_length: int)`
+  to read data from the SPI bus.
+
+Closing:
+--------
+
+- Use `ch347.close()` to close the CH347 device.
+
+Usage Example:
+--------------
+
+import ch347
+
+# Initialize the CH347 device
+ch347.init()
+
+# Configure the SPI parameters
+ch347.set_spi_config(clock=1000000, mode=0)
+
+# Write data to the SPI bus
+ch347.spi_write(device_index=0, chip_select=1, write_data=b'\x01\x02\x03', write_step=3)
+
+# Read data from the SPI bus
+data = ch347.spi_read(device_index=0, chip_select=1, write_data=b'\x00', read_length=3)
+
+# Close the CH347 device
+ch347.close()
