16 LEDrings : http://www.ucapps.de/mbhp/mbhp_doutx4_ledrings.pdf

You can read about programming voltage testing for Pic Burner in Uccaps too. "+" probe to Pin 1 , MCLR "-" probe to Pin12 or Pin31, GND , both pins are connected. Regards, Janis

Hi Read in some forums: - better to use a 12V AC adapter instead of USB, or powered from other's computer's USB port, - tWC= 8-10, tWP=30 There are many fuses for Pic Mcu's too Be patient Regards, Janis

You can made your own MB64 configuration in the setup_midibox64.asm file (open it in the Word Pad , easy to edit) . Regards, Janis

I could be wrong, but for another MBHP projects may be similar data velocities from the MIDIO128 design page : "The software captures all 128 inputs within a period of 1 mS. If the status of an input pin has been changed, the program searches for the predefined MIDI event in a big table and sends it out"

1. 74HC595 + ULN2803, 2. TPIC6B595 from: http://www.edaboard.com/topic293467.html

B40C800 0,8A 100V from datasheet. W04 to be better and can be used instead of B40C800.

:D Hi, Wilba, Chips arrived . Thank you very much ! ! ! Regards, Janis

I think, you mean a double pole power switch. It's enough for switching on and off two separate secondary voltages as 5VDC and 9VAC simultaneously. Regards , Janis

for the audio on the PC: - In the Mios Studio > Options > Midi Device Routing > You need connect left side Midi Device-Readable : Mios Studio Out Port with Midi Device-Writable : ..... ( in my computer it's Microsoft GS Wavetable SW Synth ) - For MB 64e is possible up to 8 pots in unmuxed mode(J5), editing in : setup_midibox16e.asm file

Is a plus sign is near pin 2 ? Electrolytic capacitor value partly depends on which : external or internal 5 volts PSU will be used.

From the DOUT Module additional info section : http://www.ucapps.de/mbhp/mbhp_doutx1_reed_relays.pdf

If you now using yours 5V psu with J2 its quite so ,redraw a schem without the power supply stuff at the bottom right on this schematic: http://www.ucapps.de/mbhp/mbhp_core_v3.pdf on a new maded pcb.

In the midibox tutorials may be you read about a special feature which will be assigned to the buttons : Toggle value - Send learned value with the first keypress, send zero value with the second keypress.

Hi. Mios suports your's Epson SED1278 chip LCD display. You need compare are you soldering wires as in : http://www.ucapps.de/mbhp/mbhp_lcd.pdf In your case LCD pins are grouped in the odd and even columns, but pin meanings are the same as in a one row, I think. Regards , Janis

Yes, it's right. Only , when mirrored text, pots connections looks like reversed. Redrawing some lines for better understanding. Regards, Janis

If you returned to the scheme MBHP_CORE_V3 to the connector J15, will see pins in the two columns. Right sizes first 2 upside pins are marked : B+ , B-. These pins supply voltage "+" and "-" polarity ( or need suplly voltage ) to the yours LCD backlight pins. I have simpler this part of the scheme with only one 10E resistor , but its not so important. Regards, Janis

Why 12volts to the LCD module ? If you see scheme of MBHP Core , you see only +5V and gnd connections, right? Your comments about more than 1 amp of the LCD backlight current sounds : all is not so good. You need against checked every connection to the LCD module . Regards, Janis

I could be wrong. You can use LTC out, 2nd Midi out from MBHP_LTC_V1a sch. and also add in a similar way 3rd Midi out. I think you may connect additional 74HC00 i-c to J1 MI , MO pins as in scheme are connected IC3 , R7, R8, J5 , socket components for getting needed out. Hope, you will find solution ! Regards, Janis

hey for members of another forum only, many as one year old info : http://launch.groups.yahoo.com/group/midiguitar/message/27224?l=1 but for free find only Microswitch Charts for MG-500/510 : http://jpsongs.com/troubadortech/casmgtr.htm Regards, Janis

As I understand from Pic Burner manual and : http://www.sprut.de/electronic/soft/pbrenner.htm I say : YES Regards, Janis

crimp sockets made in copper and soldering well. I made in some steps : - at first cuting and soldering ribbon cable leads,but very short lenght! When heating , insulation decreases fast, - puting on working place all needed crimp sockets together in one peace, fixing it, - then acurately soldering one by one, - after, working with a pair of flat pliers. Regards, Janis

Similar size crimp sockets I made with a soldering iron and with a pair of flat (~5mm width), long pliers. It's simply, only sometimes, need more patience. Result is fine , too. Good luck, Janis
