understanding how to configure LEDrings

Steven_C · July 21, 2003

from main.asm

;; used by lc_ledrings.inc
LEDRINGS_SR_CATHODES EQU 8 ; shift register with cathodes of the 8 LED rings
LEDRINGS_SR_ANODES_1 EQU 10 ; first shift register with anodes of the 8 LED rings
LEDRINGS_SR_ANODES_2 EQU 11 ; second shift register with anodes of the 8 LED rings

I assume I won't have to change these numbers?

can someone tell me what I have to change here to get the LEDrings working?

from lc_io_table

LC_IO_TABLE_LAYER0
;; 1st shift register
;; button LED
db ID_MBLC_SWITCH_LEDMETER1 , ID_REC_RDY_CHN1
db ID_REC_RDY_CHN2, ID_REC_RDY_CHN2
db ID_REC_RDY_CHN3, ID_REC_RDY_CHN3

db ID_REC_RDY_CHN7, ID_REC_RDY_CHN7
db ID_REC_RDY_CHN8, ID_REC_RDY_CHN8

if I modified it like this, would that mean that pin one on SR one would switch the LCD meter into a horizontal LEDring?

sorry to ask so many questions at once, thanks, from Steve

Hi Steve,

yes, the LEDRINGS_SR_* settings are used to define the position of the shift registers which are connected to the LED rings. In difference to lc_io_tables.inc the shift registers are counted from zero here!

See also this schematic:

http://www.ucapps.de/mbhp/mbhp_doutx4_lc_ledrings.pdf

it means that LEDRINGS_SR_CATHODES are located at the 9th SR, therefore number 8, and the anodes are located at SR 10 and 11.

SR 9 is reserved for seperate meters, but if you don't plan to add them, you could either change the default settings or use this spare shift register for additional LED functions.

ID_MBLC_SWITCH_LEDMETER1 switches to the meter mode, but doesn't switch back. So you have to assign at least one additional button to ID_MBLC_SWITCH_LEDMETER0

or use a single button with ID_MBLC_TOGGLE_LEDMETER for a toggle function, resp. ID_MBLC_HOLD_LEDMETER for a shift function

T...

Just seen this new pdf and i'm a lil concered, i thought your able to place the meterbar LEDs anywhere on the dout chain - not just after the vpot rings...

My design has the meterleds rings on a sep core, which is also used for the forthcoming MTC digits aswell as a single pot for the maser fader...is this still okay?, as i thought it was from a q i posted a while bak...have i got my wires mixed up - so to speak...or is just an example setup uve posted?

Best...

Yes, you can place the meter LEDs anywhere - damned! thats the problem when the application allows too much options - how to answer a simple question with one sentence when so much variations are possible? :-( You see: under these circumstances the LC documentation will never be finished... ;-)

Best Regards, thorsten.

Thanks Thorsten!

I'm just wondering, why my encoders work properly, when in the 13th and 14th SR, it says "db ID_IGNORE, ID_IGNORE ; (in my setup encoders are connected here)"

and I never changed this before I built the main.HEX file?

in the standard lc application, will the ledrings work straight away without configuring, if I just connect them to the right shift registers?

if I connect the ledrings like in the pdf, will they work straight away, or will I have to assign the SR pins in the lc_IO_table? I am using mios 1.2, as the faders go erratic when I try 1.3 (they kind of don't stop at the target position, they keep going!

Yes, you can place the meter LEDs anywhere - damned![

Your design is like Logic audio... too many options for beginners, but everything possible that an expert needs!

When I get time, I will make a step by step webpage on how to build the standard LC, with upgrade options and things... for beginners, maybe with a modular frontpanel or something! Unless someone beats me to it!

Thanks Thorsten!

If someone else can help, could they please save Thorsten from all the typing? ;)

Steven_C · July 25, 2003

don't worry about answering this, (unless it is for others) cos I probably won't fit Ledrings :P

Hi Steve,

this would be really helpfull! :)

Some infos to LEDrings and encoder settings:

buttons are "shadowed" by the encoder pins. Means: once you've assigned two pins to an encoder in mios_tables.inc, these pins will not trigger a button function anymore, therefore the appr. button entries in lc_io_tables.inc will never be processed.

digital output pins are "shadowed" by LEDring assignments. Means: the shift registers for anodes/cathodes which are assigned to the LEDring handler cannot be used for common LED functions defined in lc_io_tables.inc, since the handler overwrite the values every milisecond

Best Regards, Thorsten.

thanks Thorsten! That was helpful!

ID_MBLC_SWITCH_LEDMETER1 switches to the meter mode, but doesn't switch back. So you have to assign at least one additional button to ID_MBLC_SWITCH_LEDMETER0

or use a single button with ID_MBLC_TOGGLE_LEDMETER for a toggle function, resp. ID_MBLC_HOLD_LEDMETER for a shift function

can these functions be used to switch the LCD meters into ledring bars on 40x2? (sick of soldering!)

-> ToDo List :)
