ATtiny2313 Pin Defintions

[ko4nrbs]

This is the pin out for the Programming Header on the PCB I am using.  It is a ATtiny2313 IC.


and this is the pin out for the programmer I am using.


Which pins on the Programming Header correspond to those on the programmer? Wanted to make sure before I start programming my ICs. 

Thank you,
Bill

it's Pickit3, right? PIC is Microchip, AVR is Atmel, two completely different companies. although Atmel was acquired by Microchip in 2016.

Pickit4 should be able to write AVR. But Pickit3, of course, a debugger for PIC microcontrollers only.

I suggest buy a USBASP. very cheap.

MPLABs assured me my Pickit 3 would work ok.  I'm new at this so was doing a lot of research.  In any event I would like to find the correct corresponding pins between the two.
Thanks,

See attached file about using a PICkit 2 to program AVRs using AVRDUDE.  If you've got a PICkit 3, I believe AVRDUDE  needs it to be put in PICkit 2 mode using PICkit3 Programmer Application and Scripting Tool v3.10 and you will need to revert it to PICkit 3 mode aka: MPLAB mode afterwards.

I don't know  for sure if the same connections will work natively with a PICkit 3 under recent MPLAB X, but if the device support matrix shows PICkit 3 support for your AVR, its a fair bet they will, and its unlikely to damage anything so worth a try.

I did find this but still confused.

Microchip, PIC, Pickit, and MPLAB have nothing to do with Atmel or AVR. Not compatible; before 2016.
Since 2016, there has been integration into MPLAB and a move to an AVR architecture similar to PIC, but of course the ATtiny2313 is an Atmel-era design.


I don't think MPLAB supports programming with Pickit3.

nice information, might be able to get by with AVRDUDE.

So simply match the pin functions to column 2 of the table in my text file.  Ignore the colors, those in my file are for a proprietary PICkit 2 breadboard ICSP cable and don't match the ones on that pinout diagram.

PK2  AVR        2x3 ISP
     Signal     Header
===|=========
 1 - RST       - 5 
 2 - Vcc Targ. - 2   
 3 - Gnd       - 6   
 4 - MISO      - 1 
 5 - SCLK      - 3     
 6 - MOSI      - 4 

I will begin with these.  Thanks to all!!

Here's how I'd match that up:

Code: [Select]

PK2  AVR        2x3 ISP ATtiny2313
     Signal     header  pin
===|===========|=======|==========
 1 - RST       - 5     - 1 (PA2) + 10K pullup   
 2 - Vcc Targ. - 2     - 20 } + 100nF
 3 - Gnd       - 6     - 10 } decoupling
 4 - MISO      - 1     - 18 (PB6)
 5 - SCLK      - 3     - 19 (PB7)
 6 - MOSI      - 4     - 17 (PB5)
assuming the pinout you posted is correct.
