Hi all:
I need to create a data bus system to have the bus carrying up to 8 bytes of data which is updated and transmitted sequentially by a master MCU 16f886.
The data can be updated every 20 msec, this is flexible.
The slave PIc's (up to 8 of them) (also 16F886's) must receive their single data byte that is individually flagged . Each slave uses 1 of the 8 data bytes (8bit).
The 8 data bytes can be repetitively transmitted from the Master PIC, every 20 msec.
The master PIC is already running a code loop that cycles faster than 1msec.
The less data wires used the better.
thanks for any advice.
