Perl RPi-WiringPI Support for PIFACE Digital
Posted: 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.
