Hi, I am a complete novice to the stm32f4discovery, I have made a 8x8 RGB led matrix using 4 74HC595 8 Bit Shift Registers with only 3 wires going to my now fried arduino, from the old arduino pins I had the 74HC595 8 Bit Shift Registers connected like this; DS to datapin, ST_CP to latchpin, SH_cp to clockpin, what pins do I use on the stm32f4discovery? Are they pd8 (TX), pd9 (RX), pd10 (CK)? if anyone know please could you tell me I wouldn’t like to fry another board :

 

Thanks for any help

 

Marin.
