My Plan!

[rossmalone]

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

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
