Attiny 212 badArg("Digital pin is constant, but not a valid pin");

i am trying to program attiny 212 with arduinouno but my sketch has some problems

const uint8_t czujnikPin = 3;  
const uint8_t przyciskPin = 6; 
const uint8_t port1Pin = 1;

int x;

void setup() {
  pinMode(3, INPUT);    
  pinMode(6, INPUT);  
  pinMode(1, OUTPUT);     
 
}

void loop() {
 
  
  if (digitalRead(czujnikPin) == HIGH) {
   
    x = 1;
  }
 

  if (digitalRead(przyciskPin) == HIGH) {
    
    x = 0;
  }
 
 if (x == 1) {
  digitalWrite(port1Pin, HIGH);
} else {
  digitalWrite(port1Pin, LOW);
}
}

there is code
and the error

Which pin is pin 6?

pin6 is pa6

4

PA6 is pin 0

Arduino pin numbers, in general, has nothing to do with chip pin numbers.

5

If you prefer to refer pins by their names like PA6 - you can use long pin names directly in your code:

okay code is working but many times when i am trying to upload it i have error

How are you trying to program the Attiny212 via your UNO?

With "Arduino as ISP" ?

that's not going to work, as you need a UPDI programmer.

no no i am using jtag2updii and one time sketch was uploaded right, but after many tries most of time i have this error
sometimes there is another error
RSP_NO_TARGET_POWER
*i connected pin reset and gnd with capacitor on arduino uno and iam using 1k resistor beetwen pd6(uno pin) and updi pin on my pcb
