I have a project about designing a protocol between smart sensors. First i need to design some sensors. (I'm a beginner about ucontrollers.) I will use pic16f877 because of its ADC and SPI. I will use rs485 protocol between sensorsç But i don't know anything about addressing the sensors. Can i do it with that ucontroller and how? if anyone sends some codes it'll be better. (i use pic c compiler)
