Thanks, @xarolium, @latigid on already completed the boards - we're now working on the case and the software.

That is wonderful news, Hawkeye!  I am happy to hear we may get a second chance.  I’m still kicking myself for missing that first group buy.

Here here! I just hope I don't forget to keep on checking back with this thread. Is there a waitlist or something we can get on?

Cheers!

[latigid on]

No waiting list! There might be a teaser soon but it's hard to guess timelines at the moment. Hopefully there'll be something to tease shortly.

Best,
Andy

Any news ?

[latigid on]

We're making good progress! It's a fancy new app with a fancy new display and fancy new other things. :)

[Altitude]

was the alt-page thing ever fixed?  so you could scroll up and down in note view?

[latigid on]

No it wasn't. Peter is into the code now and would know if it can be implemented /reimplemented.

Well, from bad to worse, looks like my board is shorted now.  Not sure how that happened but I measure 2.5 ohms resistance between ground and 5V.  That was a waste. :-/

Should have updated this....an air-driven reflow station is your friend when it comes to making fixes to SMD parts!

 

This was a lot of fun to do and get working.  Looking forward to building another one day.

[latigid on]

I'm very glad; that's a great resolution! :)

hey @latigid on ... do you know how to: offset the DIN-SR-NR (Code > 32bit) ? >  i need a DINx4, in the start of the SR-Chain > then after this the BLM...

i ask because the BLM has no "Thru" Port...

i already put the blm_scalar.c and blm_scalar.h into my project (so i can change it - if necessery)

 

( i dont need any info about the LED-Part --- there i dont need a offset)

 

[latigid on]

Hello,

Not sure sorry... But you should be able to interrupt the J8/9 header with your module.

Best,
Andy

[Phatline]

to add an DINx4 module in front of the BLM16x16+x-Module, do following...

blm_scalar.c   

add  the     SR_off     Part....

/////////////////////////////////////////////////////////////////////////////
//! This function gets the DIN values of the selected row.
//! call it from APP_SRIO_ServiceFinish() hook!
/////////////////////////////////////////////////////////////////////////////
s32 BLM_SCALAR_GetRow(void) {
		
		// decrememt debounce counter if > 0
		if( blm_scalar_button_debounce_ctr )	{ --blm_scalar_button_debounce_ctr; }
		
		// since the row line of the buttons is   identical to   the row line of the LEDs,
		// we can derive the button row offset from blm_scalar_selected_row                  909  >>>>>>>>>>>>>>>>   here is the offset?
		int selected_row = (blm_scalar_selected_row-1) & 0x7; // &: bitwise AND     0x7: 7
		
		// check DINs
		int mod;
		for(mod=0; mod<5; ++mod) {	// 5: Module-Nr
									int sr = blm_scalar_config.din[mod];
									
									static u8 SR_off = 4;		// Shiftregistor Offset -- if you have a DINx4 Module before the BLM-Module
									if( sr ) {	MIOS32_DIN_SRChangedGetAndClear(sr-1 + SR_off, 0xff); // ensure that change won't be propagated to normal DIN handler
												u8 sr_value = MIOS32_DIN_SRGet(sr-1 + SR_off);
												
												// ignore as long as debounce counter != 0
												if( !blm_scalar_button_debounce_ctr ) {
													
																// determine pin changes
																u8 changed = sr_value ^ blm_scalar_button_row_values[mod][selected_row];
																
																if( changed ) {
																				// add them to existing notifications
																				blm_scalar_button_row_changed[mod][selected_row] |= changed;
																				
																				// store new value
																				blm_scalar_button_row_values[mod][selected_row] = sr_value;
																				
																				// reload debounce counter if any pin has changed
																				blm_scalar_button_debounce_ctr = blm_scalar_config.debounce_delay;

												}

wow.  this looks amazing!

Super small demo of the newest hardware variant:

Enjoy the weekend and many greets!

Hello,

 

man this is a huge setup, i think i am going to built one of those kits for myself.

I just signed up to the mailinglist in the midiphy shop.

But as soon es one is available feel free to hit me up personally, i also cold be some kind of beta tester :)

I did built the Midibox SID, it seems to work :) and the Midibox sequencer.

If i understand right this matrix controller only works together with the sequencer.

 

Thanks a lot for all that effort.

Best wishes.

or other midi devices... or you could program your own custom sequencer into the matrix (it is a32bit core now?...thats whaz i did with V1 off the blm16*16+x

[Hawkeye]

@mex very cool! We're still sourcing a few parts and finalizing documentation, as well as expanding the software a bit - so it will still require some time, but it's working nicely (the build is also already externally verified :))

@Phatline yes, 32-bit :)

Many greets and have a nice weekend,
Peter

[Hawkeye]

The new version now is finally available! Check this thread:

Best regards,
Peter

now i need this for the DOUT-Registers... i got the 16x16 working with following code .... but the Extra-XY stay dark - any Idea? cant get forward, since Latigid Ons BLM has no J89 thru, i have to put the BLM at the end of the SR-Chain (3xDIN, 4xDOUT in front off the BLM)

 

/////////////////////////////////////////////////////////////////////////////
//! This function prepares the DOUT register to drive a row					DOUT-SR-OFFSET HERE!!!!!!!!!!!!!!!
//! should be called from   APP_SRIO_ServicePrepare()
/////////////////////////////////////////////////////////////////////////////
s32 BLM_SCALAR_PrepareCol(void)	{

		if( ++blm_scalar_selected_row >= 8 )	{ blm_scalar_selected_row = 0; }

		// select next DOUT/DIN row (selected cathode line = 0, all others 1)
		u8 dout_value = ~(1 << blm_scalar_selected_row);

		// apply inversion mask
		dout_value ^= blm_scalar_config.cathodes_inv_mask;

		// output on CATHODES* registers
		u8 SRo_off = 4;	//Shiftregister offset

		int mod;
		for(mod=0; mod<5; ++mod) {	int sr = blm_scalar_config.dout_cathodes[mod];	// 5: Module-Nr

									if( sr )	{ MIOS32_DOUT_SRSet(sr-1 + SRo_off, dout_value); }	// SR-CHain: BLM > Dout....
									//if( sr )	{ MIOS32_DOUT_SRSet(sr+3, dout_value); }	// SR-Chain: DoutX4 > BLM
								}

		// output colours
		for(mod=0; mod<5; ++mod) {

									int colour;	// 5: Module-Nr
									for(colour=0; colour<2; ++colour) { // 2: Color-Nr

												int sr	= blm_scalar_config.dout[mod][colour];

																	// Module        8 Rows            Color   Blink
												u8 STEPs= blm_scalar_led[mod][blm_scalar_selected_row][colour][0];

												if (blinky && BLM_BLINK_ACT) { 	// turn of the blinking Steps

																u8 FLAM = blm_scalar_led[mod][blm_scalar_selected_row][colour][1];

																// compare FLAM and STEPs    with   Bitwise XOR!
																val = FLAM ^ STEPs;
															}

												else { val = STEPs; }


												// Set it
												if( sr ) { 	MIOS32_DOUT_SRSet(sr-1 + SRo_off, val); }	//Shiftregister offset, val); }	// SR-CHain: BLM > Dout....

		return 0;
}

 

[Phatline]

ok i got it...

if you have for example follwing Shiftregister Chain- Scenario:

DINx3 > DOUTx4 > BLM   (instead of BLM > DIN > DOUT... which is not possible because of not having a J8/9 output on the BLM)

go to blm_scalar.c

and change following:

/////////////////////////////////////////////////////////////////////////////
//! Initializes the BLM_SCALAR driver
//! Should be called from Init() during startup
/////////////////////////////////////////////////////////////////////////////
s32 BLM_SCALAR_Init(u32 mode)	{

	  // define default configuration (can be changed during runtime)
	  int mod;
	  for(mod=0; mod<5; ++mod) {// count thru Scalar Modules

								// DOUT
								int mod_sr_offset = (3 * mod) + 4;	// 4: DOUTX4 OFFSET      3: 1-Cathode, 2-Color1, 3-Color2

								blm_scalar_config.dout_cathodes[mod] = mod_sr_offset + 1;

								int colour;
								for(colour=0; colour<2; ++colour)
								blm_scalar_config.dout[mod][colour] = mod_sr_offset + colour + 2; // offset 2..3(..4)


								// DIN
								blm_scalar_config.din[mod] = mod + 1 + 3;	// 3 = DINX3 OFFSET

								}
  .......................................

have fun!
