#146402 - How much control do you have ? Responding to: ???'s previous message |
Do you have complete control of the firmware of all three devices ? Do you have control over the hardware, too ?
Maybe an I2C or SPI interface could work, the biggerst problem is that the CD-players themselves broadcast data at "any given time" (the tracktime and so on) so I must figure out how to do this with master/slave configuration. <p> Well, "any given time" is a fairly fuzzy term. What kinds of delays could the system tolerate ? (1 ms ? 10 ms ? 100 ms ?) You could set up a polling scheme in which the master polls the slaves every couple of milliseconds. Or the slaves could use an additional line to signal to the master that they're ready to send data. |
