Hi all, I am considering building various analog interface cards such as temperature-measurement, DACs, current-DACs, etc. for instrumentation purposes. Any suggestions on what would be a good way to interface these to a mesa card? SPI: +Most ADC and DAC chips seem to have SPI interfaces, but some require additional IO for e.g. MUXs or programmable-gain amps etc. +fast enough, e.g. 10MHz data clock. -How much work is this on the hostmot2 driver/firmware side? Smart Serial: +ready made hostmot2 driver + firmware -what chip/uController is used in the smart-serial device? -speed? any other suggestions? regards, Anders W |
