RS232 Coms
Posted: Mon Dec 27, 2010 3:59 pm
HI all,
I am working on a project, where I need to communicate between 4 to 8 Pics, each pic on the board, will be given a Byte value and will only run a command if this byte value is seen first, this will be done either via a Master Microchip controller or a PC,
I plan on linking up all the boards to a common point, so I can either plug in a master controller or a PC connection.
Each board will be about a inch max away form each other.
I am trying to reduce cost as much as I can, but need it to be stable as this will be used in a industrial App.,
My Questions are:
Will I need to have a MAX232 or similar on each boards and link these to a common input connection?
or can I get away with just one MAX232 on the common input connection and then link each board to this?
any suggestions would be very much appreciated.
Thanks guys
Tristan
