cool lots to go on i'll stop hassling you. I ordered my boards today from modular addict.

Thankyou once again I will look into creating a logical table the LEDS are attached to boards as are the 10 pin headers. The board is an livid rgb omni board each board has two ten pin headers for controlling led feedback. http://wiki.lividinstruments.com/wiki/Omni_RGB. No shift registers on boards. I Was going to buss the boards together with an idc cable and then create one larger matrix using sparks fun type shiftreg break out boards then to a MIDIBOX DOUT BOARD. as i have 4 positions free on SR u12 common anode columns i thought i could connect a second 72 led matrix into SR U12 via q4-q7 Really just trying to reduce the number of separate cables connecting things together As i have 9 rgb 10 pin headers in total to deal with.

hi Created a diagram of sorts,drilling this down i twould like to join 3 separate matrices 2 by 12 by pigy backing the common anodes using idc cable cascade. wires 1/2/3/4 to shiftreg U12. the the cascade cable is cut at wires 5/6/7/8/9/10 wires 5 and 8 are for blue led go to SR U11 wires 6 and 9 are for green led go to SR U10 wires 7 and 10 are for red leds go to SR 09. below is a pic Thankyou in advance or the helpi am being given Schematic_rgb led common anode matrix 74hc595_2021-01-21_01-32-30.svg

Thank you latigid on im in the process off creating my first circuit diagram, at the moment it looks like noodles intermixed with blocks however i have just been reading up on net flags and net lables so i will tidy things up this week and then post the circuit diagram.

THANK YOU LATIGID Appreciate the input have looked into the shift registers i have more questions re going from the idc headers to the shift registers. I think what i would like to do is create 3 separate matricies of rgb leds each is 4 columns and 6 rows total (72 leds) have 3 sepaate matricies. if poosible can i pm you.

Hi guys hope every one is keeping well I am a midbox newbie and i was hoping that someone could help me with led matricies I am trying to resurrect a project which i initally started with a livid diy builder platform. my question centers around rgb led matricies At present i have several rgb matricies each are 2 rows 4 columns connected to a 10pin idc pin 1 is common anode column 1, pin 5/6/7/8/9/10 are for the cathodes and are assigned to rows 123456 respectivley. Not sure what pins 234 are doing but these are assigned to columns 234 respectivley. is there a way to hard wire the 2 by4 rgb led matrices to create a larger matrix so i can reduce the number of D outs i need. I have 72 rgb leds (standard) 56 are associated with encoders i am hoping to eventually hack the board (livid rgb omni) replace the leds with connectors that go to assignable leds layed out in a strip and get better visual feedback. i would greatly appreciate any pearls of wisdom anyone would like to share. feel free to PM me.
