Software driver needed for the microchip MCP23017 I/O expander

jurato11@gmail.com on Sep 12, 2012

Hi everyone, I'm inquiring to find out if anyone has written a software driver for the ADI BF518 Blackfin Processor that controls the microchip MCP23017 16-Bit I/O Expander with Serial Interface. If anyone has written code for this and wouldn't mind sharing it, please let me know.

Thank you!

Hi Jeff,

We don't have a driver for the MCP23017 chip, but we can suggest you to use our ADP5589 part. The ADP5589 is a 19 channel GPIO (General Purpose Input/Output) port expander with built-in keypad matrix decoder, programmable logic, reset logic, and PWM generator. A generic driver for this device can be downloaded from our wiki page (http://wiki.analog.com/resources/tools-software/uc-drivers-all).

Best regards,
