Atmel programmer query

Hi,

I know I'm probably missing something really obvious but am not having much
luck with Google on this one.


I bought this kit some time ago:
http://www.matrixmultimedia.com/resources/files/datasheets/EB194-30-2.pdf

It works fine with a Mega423P, but the 20-pin socket will not work for me.

This 20-pin socket is wired as on the link above:

+5v pin 5/15
Gnd pin 6/16

MOSI pin1
MISO pin2
SCK pin3
RST pin 10


This does not agree with a typical Atmel 20 pin uC - I would like to use the
Tiny2313, which this board allegedly supports, but it can't do as
MOSI/MISO/SCK are pins 17/18/19.
http://www.atmel.com/Images/doc8246.pdf


I tried Googling to find out which uC's DO use this boards' pin
configuration but got nowhere and frustrated.

I usually learn a lot more posting on usenet than Googling anyway, hence my
post here.


Cheers,


Gareth.

This doesn't answer which *do* use the pins shown but it looks like if
you use the header J3 ("40P") then the ISP signals get routed to the
proper pins (19:SCK, 18:MISO, 17:MOSI) on the 20-pin socket. Do a
continuity check with nothing plugged in first, of course.

Hmm, this is even curiouser then:

J3 Header:

MOSI not connected to 20 pin device
MISO pin 9 20 pin device
SCK not connected to 20 pin device
RST pin 10 (all 3 headers' reset lines are commoned)


J9 header

MOSI pin 4 + Reset.


There is screen printing on the board saying J9 is for 28 pin socket, J10
for 8 & 20 pin socket, J3 40 pin socket, as also stated in the manual.




If I was Scooby Doo I'd be going "Uuuuurrrumph?"



Thanks,



Gareth.

Yes -- I was looking at the pin designations for the device (ATtiny2313)
vice the designations on the schematic. <thwack thwack>

However, it does look like there are current ATtiny chips that do have a
pinout that matches the one on the programmer. Look at the ATtiny26 and
the ATtiny261/461/861 chips and their A-rev brethren.

Ah, the *61 family is what I am looking for. Doh! Thwack!




Much obliged,
