understanding how to configure LEDrings

Steven_C · July 21, 2003, 5:41pm

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?

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, 1:27pm

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!)
