#174262 - Is the display the master? Responding to: ???'s previous message |
Johan Smit said:
The master processor runs a RS485 network to 6 slaves, and each slave returns its state on being polled.
The display is graphical, and has to respond to the slave states, the keypad, and the master state. So the Master is currently (also) the display processor? Timing is getting tight. What processor are you using? I was thinking of using a seperate processor to do the display only. How about just "upgrading" the Master to something sufficiently powerful to cope? Suggestions on how to interconnect the display processor to the system? Can't you just make it another slave on the existing bus? Upgrading the processor would, of course, obviate this need... Some more background would be helpful to give (more) appropriate suggestions... |
