AVR Freaks

I'll keep it on mind. And what of the code that I wrote, why arduino gives an error?

#define MYUBRR (FOSC/16/BAUD-1)
#define FOSC 1843200
#define BAUD 9600
unsigned char data = 1;
unsigned int ubrr;
void setup() {

  UBRR0H = ubrr >> 8;
  UBRR0L = ubrr;
  UCSR0B = (1 << RXEN0) | (1 << TXEN0);
  UCSR0C = (1 << USBS0) | (3 << UCSZ00);

}

void loop() {
  while ( !( UCSR1A & (1 << UDRE1)) ) ;
  UDR1 = data;
}

Here it is already compiled, but what variable ubbr should be?

avrdude done.  Thank you.

as you wrote)) thanks for the help) but that's what writes arduin in response to this sketch. Tomorrow I am soldering the new board, there will be all capacitors in place, I will also use external quartz to definitely exclude all variants of the "wrong printed circuit board"

n this case sketches are loaded, fyuzes are read and written. Tried to light the LEDs and standard blink, as well as ddrd portd

Maybe it's worth it ... I think it would be easier ... but that's only one thing we have about $ 10 ... not that I'm sorry, it's just that something can not happen again ...

I have nothing and is not confined anywhere

But you see everything there. And the components are signed

it's a matter of days gone by, now the problems are completely different

Well, really, you really think that I would not have noticed this

It's not solder, it's dirt, well, I'm not an absolute beginner in this business, I've been soldering and much more complicated things, I will not allow such an elementary mistake. I have a multimeter and it's not possible to install any pin at all (not just the one on which there is no LED)

There is perhaps a small nuance, the two previous boards had a signatureavrdude: Device signature = 0x1e9803
avrdude: Expected signature for ATMEGA2561 is 1E 98 02while this 2561 has the correct signature ending at 3 (although the MK is from the same batch.) Tomorrow I will get a microcontroller 2561 from a trusted store, and I ordered these in China (and as a result, one local 2561 cost me like 5 Chinese ((() But I do not think that the Chinese 2561 are unoriginal ... the same 328 I ordered 20 pieces from them and everything is fine.I also want to clarify that the LED on the previous cards it turned out.

" I find the GND and power traces to be a bit "skimpy" what this means, do not quite understand. Are the paths too narrow?

"have you checked the pin with a VOM or SCOPE during your blink test?" you mean a multimeter or what are those abbreviations (abbreviations)

I have quartz at 8 MHz

The simplest code, in order to at least check the LED

void setup() {
  DDRD = 0b11111111;
}

void loop() {
  PORTD = 0b11111111;
}
