Adafruit_MCP230XX : wrong adresses for MCP23008

[aboudou]

Hello,

The code for Adafruit_MCP230XX uses wrong adresses for MCP23008. To make it work, I had to make the following changes (addresses come from MCP23008 datasheet)

MCP23017_IODIRA = 0x00
MCP23017_IODIRB = 0x01

MCP23017_GPIOA = 0x12

MCP23017_GPIOA = 0x09
MCP23017_GPIOB = 0x13

MCP23017_GPPUA = 0x0C

MCP23017_GPPUA = 0x06
MCP23017_GPPUB = 0x0D

MCP23017_OLATA = 0x14

MCP23017_OLATA = 0x0A
MCP23017_OLATB = 0x15

It would be better to define mcp23008 constants as I proposed.

Should be fixed ... I just tested with an MCP23008 and it works for me

Thanks for the fix.

I can confirm it works with an MCP23008.
