I2C hardware + I2C software on the same chip

Post by WalkOver »

Hello !

Is it possible to have one I2C hard AND one I2C soft on the same chip ? I tried but without any success.
I'm working on a port expander but I need more than 8 MCP23017 ( 12 exactly ).
(I will use 18F6527 or 8527).

Thank you for your help !

Flowcode V3 only allows selection of one I2C component. V4 allows multiple I2C components to be selected (only one can be hardware, the others must be software - using unique I/O pins).

It is possible to add extra software I2C busses to Flowcode V3 either directly in Flowcode, or in C using a custom component.
