Yes, I have outputs on both channel 1 and 2
It still seems somewhat noise related. Even the first time I had it working, I had to stop and start a few times (power off and on) the device, and then suddenly it worked.
And then after I made my loom again it did not work, and after a few restarts it did. Whenever it does not work, green led stays on.
Key is that green led. If it turns off, you are initialized and it works, outputs nicely follow PC controls.
I think the noise makes it sometimes fail initialization. The pullup helps, but does not eliminate all noise, so its a bit of a try-again game.
You know, I used to work with audio frequencies, and breadboard and ad-hoc wiring is OK. But whenever I try and go about a few MHz, I find that all that spagetti wiring is really disruptive. Stray capacitance, inductance, loops cause all sort of ugly signals.
Here too, I think if we want reliable testing, we should solder a BP to a proper veraboard and proper headers directly for the FY6600 connectors, without any breadboard wiring in between.
PS: with no PC control, the BP seems to send out a channel 1 10KHz 2V square wave by default. So first keep USB unconnected, and turn on/off the FY6600 and/or reset the BP
