Hi Mike! Thank you so much for the great work~!

I attempted to connect Raspberry Pi Pico w to an MCP23017 and encountered the OSError: [Errno 5] EIO.

Raspberry Pi Pico was able to find the MCP23017, but the error shows up when creating an MCP23017 class
mcp = mcp23017.MCP23017(i2c,0x20)

could you help me with this issue?

It turns out is just me fried my raspberry pi pico pins during soldering...
