I’ve decided to go ahead with my midibox64 project.
I’m planning a design with
53 rotary knobs
11 faders
32 buttons
11 Leds
and an LCD!
The plan is to use
1 Core - PIC18F452 (Kit from Mike’s)
2 AINs (Kit from Mike’s)
1 DIN (Kit from Mike’s)
1 DOUT (Kit from Mike’s)
Plus:
LCD 16x2
LED, red 3 mm
from Mikes
11 faders
53 rotary knobs
32 buttons
(from RS).
I want to build the device on breadboard and then transfer into a box when it works!!
Is using 11 LEDs on a DOUT going to lead to issues?
also, is using only 1 DOUT and DIN going to cause problems?
if any one has any ideas, help or anything get in touch!
heres a photo of a very rough layout!
Cheers

no & no

It looks to me, that you’re driving 10LEDs from the DOUT. - It makes more sense to hook the Power-LED to the 5V side of the PSU.

It looks to m e like 8 Leds. 2 are for midi in /out. They should be connected to a ltc. Power led like screaming rabbit said

from main.asm
; For MIDI activity monitor: define the DOUT pins for the Rx and Tx LED
#define DEFAULT_MIDI_MONITOR_ENABLED 1 ; if 1, the Tx/Rx LEDs are enabled
#define DEFAULT_MIDI_RX_LED 0x40 ; DOUT SR#9, pin D0
#define DEFAULT_MIDI_TX_LED 0x41 ; DOUT SR#9, pin D1
