In that case, I misunderstood the purpose of the cheat-sheet.  I assumed it was meant to document pin mappings for Arduino compatible cores.

[Reply #16 on:]

You didn't misunderstand: The new version of the cheat sheet was meant to do exactly that: For example, physical pin 11 on the ATTiny2313/4313 is PD6 (when programming in low-level avr-gcc) and is assigned to Arduino pin number 8: This is written as PD6/D8 in the cheat sheet.

In that case, PB3 needs to be excluded for the X5 family.  As far as I know, no Arduino compatible cores make use of inverted PWM outputs.

[Reply #18 on:]

You won't be able to use the inverted PWM for Arduino, but the sheet covers both Arduino pin numbers and normal port numbers (that's why it says D3/PB3). That said, there should be a note saying that PB3 is a "special" PWM pin.

Hey Karl_B
thanks for this cheat sheet, looks great. Wonder if you could also include attiny84 ?

[Reply #20 on:]

Thanks kermit,

attiny84 and attiny87/167 are on our TODO list.

[Reply #21 on:]

Good news, we have now added ATTinyX4 as well to the cheat sheet, you can find the updated version here: http://www.akafugu.jp/posts/resources/reference-sheet/

Nice.  Thank you.

I have a suggestion: use ", " (comma space) instead of "/" (slash) to separate the labels.  It's a little difficult to locate a pin from its function (like MISO).

[Reply #23 on:]

Thanks for the suggestion, we'll try it out and see how it looks

[Reply #24 on:]

Great post.
do you guys know what is the analog input pin numbers on the  2313
been reading the datasheet  and can not find it.

thanks

[Reply #25 on:]

For the analog comparator or the analog-to-digital converter?

I  guess the analog is the PB0/AIN0/D9

I have been trying to get the  analog input to work with a sensor
how is set this pin to be a alaog input

see sketch

Code:

///////////////////

int sensPin=PB0; //  analog  input  for  2313
int sensVal=0; //  value





int ledPin = 1; // The pin number of the LED  
int ledPin7 = 7;


//////SETUP////////

void setup() {
 pinMode( ledPin, OUTPUT ); // Sets the led pin to an output mode
 pinMode( ledPin7, OUTPUT );
// pinMode( sensPin, INPUT );
 
// Serial.begin(57600); //set Serial Data flow / debug/ read
 
}



///LOOP///////////

void loop() {
  
  digitalWrite(ledPin7, HIGH);
  
  
 sensVal = analogRead(sensPin); // READS sensor,  
 
 

 
 if( sensVal > 350 )            // object is close to sensor??
 {
  
  

    
       digitalWrite( ledPin, HIGH ); //Turn  LED pin on
     }
    
    
    
     if( sensVal < 450 )
 {
  
  

    
       digitalWrite( ledPin, LOW); //
     }
    
    
    
   }

An analog-to-digital converter.  The 2313 does not have one.

[Reply #29 on:]

That is one of the two inputs to the analog comparator. 

Code:

sensVal = analogRead(sensPin); // READS sensor,
