#181218 - Either help with real-time or with wire count/length Responding to: ???'s previous message |

I see more potential in the low-end low-pin-count (and cheap) microcontroller than just be a controller of a simplistic device - "toy" - application. It has been discussed here more than once: they provide a nice way to split functionality in a more complex design.
While there are already "multi-core" devices around, they may be less flexible than a "let's stitch it together from these cheap chips" solution. JW Yes, but that was in some part what I meant. But for two different reasons. - On one hand get an extera set of interrupts etc, making multiple small processors into threads in a larger design - each with its own real-time requirements. - On the other hand to move some I/O way out from the master processor without needing lots of long I/O traces. In an lift, you may have a lift phone with buttons to call for help. But these buttons (with required pictograms) may be far away from the central unit with the phone line or GSM modem. So it may be meaningful to have intelligent slaves inside the cage, on the roof and below the cage. But the problem with wires are everywhere. A LCD monitor may have lots of electronics. But maybe not where the LEDs and control buttons are. |
