Hi Dave! Awesome explanation!!!
I started already reading about the _hw.tcl, as I received this recommendation already. Writing my own?? I think this is still a bit too... but I'm getting there to understand it better, I think. So, I understand the naming of the conduits is really up to me, how I like to group my signals, e.g. a SPI group, and an I2C group, i.e. in my easy example, read/write which is all the same data conversation would be fine in the same conduit, anyway it doesn't make a practical difference to use plenty of conduit names. Great! Thx!
