Lazy?

Yes I am lazy.
But not to lazy - measuring current is tiresome
This makes me want to try two different +5V for the VCC%Ds.
Thanks!

PS. Can you see any variation in current one either of them while playing audio?
I might as well tell as you otherwise will never stop asking
one VCC5 (pin 2) is for the FPGA Core voltage DC-DC switcher, the other (pin 1) is for everything else, via the 3.3V lin regulator.
I don't see any big advantage by using two 5V regulators, but I have noticed that some people have different opinions here
I use Aten UC232A USB to RS232 adapter try to connect to the uManager of dam1121
USB to RS-232 Adapter (35cm) - UC232A, ATEN USB Converters | ATEN ANZ
Unfortunately I can't invoke the uManager. What was wrong?

The most asked question...

Yes.
I tried hundred times before (in dam1021 and dam1941), sometimes it works finally so I can upload firmware. But most of the time it failed. I never remember how to make it works.
Therefore I tend not to connect to uManager because I am lazy to try.
The answers are in the thread. I once had brain fade (not for the first or last time) and took the easy way out and asked here. But it is a longish read if you’re in a hurry (or lazy
) and as I’ve just had that essential morning espresso.... Of course you know the 1121 interface is TTL. Like the isolated TX/RX on 1021. So a different PC-to-1121 interface is needed compared to good old RS-232 as used for the non-isolated connection on the 1021. But you know this.
From memory, with the communications software I’ve used (HyperTerminal), in my setup, YMMV depending on what you use, yadda, yadda I find it necessary to set the software to NOT append line feeds and NOT send line ends with line feeds under ASCII Setup.
Hope that eases the state you’re in....
Thanks for your big hint. Dam1021 has two kinds of connections available, one is non-isolated RS232, another is an isolated TTL.The answers are in the thread.
