This device has an MCP23017 connected to it as shown below and apparently worked under R120
I had the I2C set up as follows under R120:
I have similarly configured Mega 20111 as follows:
Now however, when I enable the mcpgpio device, my log fills up fast with
Code: Select all
6621858: MCP : Port=0 is offline (EVENT= -1)
6621860: EVENT: mcpgpio#Switch=-1
6621958: MCP : Port=0 is offline (EVENT= -1)
6621960: EVENT: mcpgpio#Switch=-1
6622058: MCP : Port=0 is offline (EVENT= -1)
6622060: EVENT: mcpgpio#Switch=-1
6622158: MCP : Port=0 is offline (EVENT= -1)
6622160: EVENT: mcpgpio#Switch=-1
6622258: MCP : Port=0 is offline (EVENT= -1)
I fail to see where I have gone wrong as yet. Thoughts / advice would be appreciated.
Thanks,
