only one ledring for multiple encoder?!

[bosone]

i'm currently building my new midibox, and i will mount both 16  pots and 16 encoders.

but i have decided not to mount 16 ledring for each encoder (TOOOO much work...), and to use them without indication.

but i was thinking this:

is it possible to mount only one "ledring" (in the form of a meter... i.e. not a "ring" but several led in a straight line) and assign this only one ring to every encoder?

my idea is that, when i move an econder, this single ledring will monitor the state of the encoder that i'm moving.... swithcing its state depending on the encoder used in that moment....

i will not monitor the status of every encoder, but only see a single  encoder value...

Hi Matteo,

it's impressing that you are never giving up to save money and effort ;-)

A change should be simple, open mb64e_ledrings.inc and replace following lines:

	incf	MB64E_LEDRINGS_CTR, W, BANKED
	andlw	0x0f
	movwf	MB64E_LEDRINGS_CTR, BANKED
[/code]


by:

[code]
	;; always display status of last modified encoder
	movff	MB64E_LAST_ENTRY, MB64E_LEDRINGS_CTR

Best Regards, Thorsten.

ahaha!! :-)

thorsten, you are right!

i try always to achieve the maximum i can with the minimum expense...

also this is part of the funny to build the midibox! :-)

there is always the behringer BCR control to buy, if one wants the simple  things!!!

(this topic could also be name: "one ledring to rule  them all".... i'll throw my MidiBox in the flames of  Mount Doom... ;-) )

uhm.. i tried but it didnt worked. when i change encoder, the leds simply turn off... by:

	;; always display status of last modified encoder
	movff	MB64E_LAST_ENTRY, MB64E_LEDRINGS_CTR

How did you connect the cathodes of the LEDs, and to which shift registers (SRs) are the anodes connected?

Best Regards, Thorsten.

[bosone]

the connections are the one indicated in hte schematic.

only one ledring is presetn: the cathode to SR1, and the 11 leds to SR 3 and 4...

So, with a single LED ring it makes sense to connect the cathode line directly to ground, so that it is always powered
