Text LED Panel

[Fluence]

I've inserted 1280 LED, but anyway there's no need to add more, even if i wanted i can't because the "limits" it's kinda dissapointing having such limits, but aw well...

For now i need to know how to connect the 74HC595 on the ATMega32. I have the first schematic saying how to connect them to the older microprocessor, but since i will use ATMega32 the connections may be different.
The pins i need to know where to connect are: G(13), RCK(12), SCL(10), SCK(11), SER(14).

If it's like the other schematic i need to connect like this:

G(13) connects on ATMega32 - PD3/INT1(17)
RCK(12) connects on ATMega32 - PD5/0C1A(19)
SCL(11) connects on ATMega32 - PD4/0C1B(18)
SCK(10) connects on - VCC
SER(14) connects on ATMega32 - PD2/INT0(16)

Do you thinks this is correct for the ATMega32?

Here's the schematic if you want to take it a look: View attachment Message Displayv3.zip

SCK is 11. /SCLR is 10.

Look at the Serial Peripheral Interface on the Mega32. It would allow you to write 8 bits with a single instruction. I think you could consider connecting:

SCK(11) to ATMega32 PB7(SCK) (shift register clock)
SER(14) to ATMega32 PB5(MOSI) (shift register data)

others:
/SCLR (10) to VCC (shift register clear) - consider assigning to a pin so you can blank the display?
G(13) connects on ATMega32 - PB3/OC0/AIN0(4) (output enable)
RCK(12) connects on ATMega32 - PB2/INT2/AIN0(3) (register latch)

But i can't connect anything more to PB3, PB4, etc, because that pins are controlling the LED. D:

About SCLR, yeah it would be much better if i assign a pin to clear it, but what should i choose?

Sorry for being kinda lost on ATMega and microprocessors, but i've never touched this subject before, so it's all new to me. :3

Hello
This led displey but I did have some problems. Installation works but does not display the characters correctly. Instead I used at90s2313 ATTiny2313. Request if somehow you hex me for ATTINY 2313.
Thank Doru68
