[Can I send data via uart from Analog Discovery 2?]

Thank you. This is what I needed:

dwf.FDwfDigitalUartTx(hdwf, rgTX, c_int(sizeof(rgTX)-1)) # send text, trim zero ending

 

Line above is from this example (

But it would be VERY VERY useful if I could just write and send data from here:

 

[Can I send data via uart from Analog Discovery 2?]

Hi guys,

I'm messing around with some modem and I have lost FTDI uart to usb converter.

Can I use WaveForms and Analog Discovery 2 to send uart data somehow without bit-banging digital out?

If its possible - maybe someone has script example?

[Are there any plans for Analog Discovery 3 with deeper memory?]

AWESOME! 

And that linux on board...

But such awesome instrument will probably cost 3x more than AD2 and I will be not able to afford it :(

 

[Are there any plans for Analog Discovery 3 with deeper memory?]

Hi guys,

Are there any plans to release new version of Analog Discovery with a bit deeper memory? 

It is awesome instrument, very useful even in professional work. I have found that in many cases is waaaay better than some regular low cost scopes (like my 4ch Rigol MDO where XY mode is useless, there is no way to store setup, firmware is buggy etc.).

There is just one little problem: not enough sample memory. I'm forced to use Record feature sometimes when just 2x more memory could do the job. 

Can we expect AD3 with a bit deeper memory in near future? Probably 256k would be enough...
