Hi,
Once again, i am here ^_^. I suppose i'm quite familiar now.
Anyways, I would like to ask some tip about the optimal communication setup for my circuit. I have a Energy Meter IC (ADE7953), RTC, Heat sensor & MCU. I am planning to use I2C protocol for the Sensors and MCU, while UART using USB to UART chip for MCU to computer interface.
My question is this okay? in terms of practicality? I am thinking to separate the USB to PC interface from the rest of the Sensor so that it would add a bit of protection for my PC should there be some fluctuation in the high voltage side of the Energy Meter IC. By the way, can I trust the ADE7953? and omit using optocoupler (just to save some money :-D).
Also in terms of software implementation, will this setup cause future problems? To make my question more general, is it okay to implement different communication protocols (ex. I2C, SPI & UART) controlled by one MCU?
Thank you guys, as always!
