I am starting a project to replace an analog controller and anticipate using a BBB. I am just looking for information to get started so I can do the work/have the fun. I need a lot of I/O connections. I think that I will need to control about 6-8 relays and read about 12+ relays plus I would like some A/D inputs (temperature, humidity). Some of the relays that I will control will switch 12VDC, but some will switch 2-5 amps at 120VAC. The relays that I will 'read' will probably be at 12VDC, hopefully using interrupts. In the past I have used Omiron LY1F and LY2F relays (12VDC and 120VAC coils) which have worked well for over 10 years. I know that I can buy capes for I/O but can I combine them to provide more I/O channels? If so, how? Where can I find this information? Should I purchase a book? What do I need to look for in a cape to select one/some that can provide this expansion? I have read that I can use I2C for address selection. Where can I get documentation for doing this? I know software well but not hardware.
