First off - this has to be said - i’m utterly new to Particle/Spark development, and my knowledge of code in general is quite limited, so please bear that in mind
Right then - the project that I have in mind requires a multitude of digital IO pins for a load of switches and LEDs - 8 digital IO just isn’t going to cut it. I’ve stumbled across this particular bit of kit PCF8574T Module IO Expansion Module For Arduino and it touts itself as a stackable 8-pin IO expansion running off of i2c.
The only example code that I have been able to find (towards the bottom of that page, although that code is replicated elsewhere on the internet) sets P0-P7 on the expansion board to a high signal, and it’s doing that through a
I, on the other hand, could do with P0-P7 being initialised as individual pins (in both input and output modes) - has anyone had any experience with this particular IO board, and has anyone done individual pin addressing on it?
Any assistance in this one will be sincerely appreciated.
