Hi!
I'm working on a compact aquarium controller with Ferduino software. I've made a board with 8 solid state relay (Triac BTA12 and MOC3043M) all controlled by a PCF8574.
Can I use this expander with Ferduino to replace PCF8575 (with all the changes that are needed)?
Can you suggest me the best way to change it? With PCF8574 outputs I'll control the heater, the chiller and some other things with the timers integrated in the software.
Also can I use the same I2C bus (SDA pin 20 - SCL pin 21)for both DS1307 RTC and PCF8574?
Thank you very much
Simone
