Hello.
On this page http://radiokot.ru/circuit/analog/receiv_transmit/12 you can find two different schematics. Which one to use ? Also, what firmware to use ( because there is several of them posted here )? I tried to simulate schematic in Proteus, but it's difficult because it's not real time ...

Hello from Belgrade. I made this preamplifier ( using TDA7313 ), but have problem with display ( see picture ).
Previous time Nastya helped me with this problem, but now he did not respond on my e-mails. Btw "problem" is in display controller KSA006.

Hello.
I tried to simulate project min8 in Proteus. But simulation failed because "AVR CPU is out of memory size" error.
Why is this happening ?
