The 'A' version of the MSP430 offers even better performance when released. The MSP430 controls and samples up to 1500 12 samples per second from multiple analog inputs while sleeping 750 msec out of each second. The Zarlink offers two way communications (keeps the device synced with the PC). The data transfers are managed by the MSP430 DMA through an SPI port to the Zarlink. We should end up with 1 milliamp current draw at maximum throughput of 3000 bytes per second. -- kc0ukk at msosborn dot com _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
