#158785 - further explanation? Responding to: ???'s previous message |
Joe...can you share more of it? im just planning to do that slave thing...but its not of my priority, but if it will take less time...then ill make one...and on your project, if you have control on both side(master and slave), i think its easier..
What im really thinking is, using SPI protocol, slave would response to the master, and also the master would response with the slave, just like acknowledgment... How come, speed really matter lot? |
