Perl RPi-WiringPI Support for PIFACE Digital

Wed May 29, 2019 6:39 pm

The GPIO explander documentation for Perl Modul RPi-WiringPI describes the support of the GPIO expander MCP23017. Is the SPI GPIO expander MCP230S17, which is used by PIFACE Digital, also supported? What address parameters should be used? At wiringPi, 200 must be given as the base address.

The SPI version is not supported in the RPi::GPIOExpander::MCP23017 distribution, as I don't have an SPI version of the chip for testing.

Currently, it only supports the i2c model. I'll update the software if I ever get my hands on the SPI version.
