Re: How important is Linux?

and the only code we have on the RC is code to send input updates and receive output updates (only 5 lines of code (and a lookup table (It's dang fast))).
Since there is no code within the user PIC processor - which PCI boards are you using to do data aquisition (analog and digital) on the PC? How expensive were they? Did you find it difficult to write the linux drivers for these boards and for the sonar, gyro, accelerometer, etc. drivers? What was the interrupt latency you measured? Really interested in this last one since latency needs to be down under 20us for things like the GTS sensor. The only unix kernel I know of that has decent real time latency are unix kernels built on top of the MACH OSF/1 microkernel.
