Peter,
?
I have been experimenting with getting CW to work smoothly on this device.? Previously I had published a modification that I made to sbitx_gtk.c which turned off the water waterfall (and more) on the dual GUIs whenever the device was in Transmit Mode.? That made it much more responsive in CW Mode.? Especially when using a Straight Key.??However, it still stutters if it is off doing something else whenever it should be switching right into Transmit Mode.
?
Today I setup the DASH input pin as a pin IRQ.? That works.? I have it switching into Transmit Mode immediately on a key down.? But I have been struggling with figuring out a way to pass the key-down / key-up state form the IRQ processing routine to the complex string of CW processing functions.? I have not given up on that.? But I'm out of time for today.
?
So, I don't think it is so much the load on the device, although running waterfalls on two GUIs contributes to that load.? I think it is more of a control issue.? Just an opinion.? ?
?
