hi all, today i spent the whole day adapting PSC08-12 display to work with the LEDmicroreader project. Although the difference in the name is minimal, the pinout is completely different, and willing to keep the awesomeness of direct soldering i had to rebuild the font table. here in europe it appeared to be a big problem to find PSC08-11, only -12 which don't even have a decimal point working... poo poo, however, here is my creation, i hope it will save someone like me a day of unusually unhuman binary operations: PSC08-12 font table:

it all would be probably useless without the soldering instruction:


all pins on the right side of attiny2313 go directly to the display:

19 -> 1
18 -> 2
17 -> 3
16 -> 4
15 -> 5
14 -> 6
13 -> 7
12 -> 8
11 -> 9


left side is less lucky

2 -> 18
3 -> 10 <- attention!
4 -> 16
5 -> 15
6 -> 14
7 -> 13
8 -> -
9 -> 11
10 -> 12 <- cathode

pin 8 of the attiny doesnt go anywhere!

now happy soldering Wink

Thanks for documenting all of that-- I'm sure that someone (like yourself) will find it pretty darned handy! Big Grin

just noticed a mistake,
the left side wiring shall be read as


2 -> 18
3 -> 10 <- attention!
4 -> 16
5 -> 15
6 -> 14
7 -> 13
8 -> -
9 -> 11
10 -> 12 <- cathode

pin 8 of the attiny doesnt go anywhere!

I've edited the post above to reflect the changes-- better that a "wrong" set of instructions isn't around anywhere!
