In this forum I read (https://industruino.com/forum/help-1/question/ind-io-digital-io-voltage-168) that to handle a 24 I / O, the IND.I / O uses an ITS716 Infineon chip. I have checked the datasheet of ITS716 and I have been able to understand how to handle outputs, but it is not clear how I handle inputs (using the same pin)
Any tips for implementing a Digital I / O port on PROTO kit?
Hello, I am quite confused.
Ind. I/O and Proto are different hardware, which one are you interested in?
The output chip only handles output.
Both input and output are handled via I2C by means of a PCA9555 16 bit I/O chip.
All the needed commands and setup are cantained in the Indio library.
