idea/request led_mode=

[Zam]

Hi

Just an idea, not a real need (but it can be fun, and i will use it for sure)

something like a led_mode=blink for .NGC with associate parameter blink:on:100:off:300 for time in ms for each led state?

or defined time with 2 value map

or just 3 "blink" predefined mod, blink_slow, blink_mid, blink_fast

Anyway, the idea is to have a blinking led function when led is on, because a NGR script (set led and delay) is stopped a soon as another section is called

Hi, I come back with this.

Nobody interested? Or I miss some NG strategy already available to perform this?

I'm just thinking out loud, but maybe it's possible to use the dimmed= with very slow PWM setting, if the frequency is not locked by the sr clock ?

Hi

@Zam

I'm intrested in something like that too.

I'd like to indicate the speed of a lfo or arp/seq via smooth pulsating (fade in/out). Hard blinking would be useful for other things.

Hi

I'm still interested for such blink led function

If anyone have an idea ?

The leds do that on the matrix in the midi box sid. Maybe you could look in the code there for inspiration. Also there is the beat led on the midi box sequencer to look at as example.

Hi Gerald

Tks for info, I'm not aware of that, I only use NG with my custom controller/fader

I'll look at it !

My programming is very beginner level or I would help out more. Good luck with it!

I created some metas by myself already. So aren't you able to create a meta, that switches an LED (which is part of the meta-event) on and off with a delay of x-ms? I don't see why this shouldn't work... but I never tried it by myself... you could even add the delay to the meta-message. It's very easy to set up. You just have to edit the mios32_event.c and .h. You can use an already existing meta as example.

My C skill is not that good, but that's a good idea, I'll give a try asap

I can do some tests today evening... I'll let you know!

[Zam]

Can't say no :)

side note

I just have a look,

Also at mbng_dout.c , maybe another route is to have a non static value for DIM function or to add a condition at LED set for a specific value ?

I'm thinking out loud...

I tried it and I had no success. The first problem I ran into was, that the MIOS32_DELAY_Wait_uS only allows values up to 65535us.... not much. I will do some more tests.

[Zam]

For sure 65ms period for blinking led is fast...

I'll see what I can try too

Maybe TK will chime in and give us some clue

Hi

At mios32_timestamp.c

does this can be used ?

/////////////////////////////////////////////////////////////////////////////
//! Use this function to get the delay which has passed between a given and
//! and current timestamp.
//!
//! Usage Example:
//! \code
//!   u32 captured_timestamp = MIOS32_TIMESTAMP_GetDelay();
//!   // ...
//!   // ... do something ...
//!   // ...
//!   u32 delay_in_ms = MIOS32_TIMESTAMP_GetDelay(captured_timestamp);
//!   MIOS32_MIDI_SendDebugMessage("Delay: %d mS\n", delay_in_ms);
//! \endcode
//! \return the delay between the given and the current timestamp
/////////////////////////////////////////////////////////////////////////////
s32 MIOS32_TIMESTAMP_GetDelay(u32 captured_timestamp)
{
  // will automatically roll over:
  // e.g. 0x00000010 - 0xfffffff0 = 0x00000020
  return timestamp - captured_timestamp;
}
