Bom, é mais ou menos isso que o knob_all já falou; é esperar o inÃcio do mês e começar a vaquinha. Vou entrar em contato com a Giga pra ver se eles têm fotos das placas já prontas, para termos uma idéia do acabamento. Quem conhecer alguém que queira começar, chama para o fórum e vamos começar - são só 10 unidades - 4 já certas.
Mais novidades, respondo aqui.
p.s: fazendo uma busca rápida, não achei nenhum dos outros PICs (18F4620 ou 18F4685) no Brasil - não valeria à pena importá-los?
Aqui +1 para a vaquinha
Na farnell tem +de 500 peças R$31,37 + impostos/sedex http://www.farnellnewark.com.br/cimicrocontrolpic18fxxx40mhz40pdip,product,89H0709,1271.aspx

Hi,
May be this is not new for advanced users.
This XR-2206 Monolithic Function Generator is very usefull to use with analog out module, for example to control 3x XR-2206.
Low-Sine Wave Distortion, 0.5%, Typical
Excellent Temperature Stability, 20ppm/°C, Typ.
Wide Sweep Range, 2000:1, Typical
Low-Supply Sensitivity, 0.01%V, Typ.
Linear Amplitude Modulation
TTL Compatible FSK Controls
Wide Supply Range, 10V to 26V
Adjustable Duty Cycle, 1% TO 99%
Waveform Generation:
Sweep Generation
AM/FM Generation
V/F Conversion
FSK Generation
Phase-Locked Loops (VCO)
FM OPL3 and SID are hard to find parts, so this XR are too cheap and easy to find.
Any inputs are wellcome, let´s do it.
-
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
Yes, I discovered this today that we dont need core connected to listen the sounds from keyboard, this is too simple, I did many search here but there is nothing about this.
-
That´s OK I´m stopping by now and reading/learning:
Introduction to uCApps.de
http://www.midibox.org/dokuwiki/doku.php?id=introduction_to_ucapps.de
- recommended reading! 98% of all newbie-questions in the forum are answered in here
Thanks for all inputs
-
OK this first lesson I got it and is OK.
Now the second lesson.
Was loaded the MIDIbox 64e I'm using the MIOS Studio midi keyboard controler, MIDI has DATA out but no audio on the PC.
There´s only 5 pots in unmuxed mode(J5)
-
I'm having a bit of trouble understanding the problem.
You say that Pin 25 RX has no outgoing data..
Pin 25 is TX, pin 26 is RX..
You show in a pdf that you uploaded MIOS in smart mode.
For this to happen, both TX and RX MUST be working, or the upload would never have completed.
SO the problem is not TX or RX... or you never would have made it this far.
You have demonstrated so far that you have working MIDI IN, MIDI OUT, and LCD display.
Sounds like you are doing quite well. Next is to upload your application.
Good Luck,
LyleHaze
Yes Pin 25 is TX sorry for my confusion.
mios_v1_9f_pic18f4620.hex was programmed
s_v1_9f_pic18f4620.hex was uploaded
You said
"Next is to upload your application"
What this mean?

Hi!!
There is a PIC ID Value Calculator here
http://www.avishowtech.com/mbhp/idgen.html
For PIC18F4620
PIC ID Header: 0000 0000 0000 0000
This is the same I´m using but no way, no DATA on pin 25.
This is the LCD message start:
MIOS V1.9f
© 2007 T.Klose
and them
READY
I´m feeling too bad, why me???
-
Thank you for your help.
Elnec SmartProg2 is a profissional programmer, this is best them ICD2BR, I have beem programed DSPIC/PIC/ATMEGA88/AT90S2313 and many others.
Flash Microcontroller Programming Specification "39622F.pdf" page 9;
"Users may store identification information (ID) in eight
ID registers. These ID registers are mapped in
addresses 200000h through 200007h. The ID locations
read out normally, even after code protection is applied."
SmartProg2 GUI let user store ID location.
Could someone provide correct ID location for 16F4620?
ID Location 1=?
ID Location 2=?
ID Location 3=?
ID Location 4=?
ID Location 5=?
ID Location 6=?
ID Location 7=?
ID Location 8=?
Hey AC, I will write something in English, so it's better to everybody understand.
It's sad heard that you are finding problems in your project. Which project you are building?
You know, I'm just a newbie here but did you already made all of the midi test/troubleshooting steps?
Try to post your tests here.
Home-made pcbs maybe can be your issue too, and I would suggest you another application to burn your PIC. Anyway, if you have a free time, you can build an MBHP BURNER or even the out-of-date JDM Module.
Good luck troubleshooting your project, and I hope to hear good news in soon!
K.
OBS to AC: AC, to planejando fazer uma 'vaquinha' para mandar fazer uns cores v3 numa fabrica aqui dor Rio, então se tiver interessado em entrar nessa vaquinha para pegar um core para você, mantenha contato, pois uma placa profissional pode lhe ajudar no seu projeto

Now LCD is READY not DEAD.
I´ll try to explaim step by step all procedures for newbie like me.
Please look PDF for more clear undestanding, english is not my native language and some time I have some difficulties to explaim what I´m thinking.
1-I made my mbhp_core_v3b using an universal PCB this is very easy to build and better them protoboard, anyone can do this without buyng an industrial PCB.
2-For people like me that have a programmer like SmartProg2, you must check "Ignore Microchip Recommendation to let most Significant Niblle of each ID to be Fh" this is the secret for not have anymore "Received Unxpected MIOS SysEx message"
3-Take care with MIDI IN/OUT, "Rear View" means exatily "Rear View" see this in PDF atached, that show MIDI Front View.
But here I have no "FLOWERS" there´s no DATA outgoing pin 25 TX, PIC is not dead, I did MIDI OX tests and before upload mios was receiving DATA on MIDI MONITOR IN
Well, any suggestion???
-
I did software implemented loopback test with MIDI OX, everything OK.
I´ll try this tomorow
TEST SW2: (only relevant if you've programmed the bootloader with your own PIC programmer): some PIC programmers are not able to modify the ID field, which specifies the MIOS device ID, the LCD type and especially the to-COM option (alternative baudrate). This wouldn't be a problem so long the ID is completely zero (common case), but unfortunately the ID field is FFFFFFFFFFFFFFFF by default. This program fixes the ID field, details are described in the main.asm header -
Fixed? this is not true...
Started again
Erased all PIC18F4620
LCD is new one.
Uploaded mios(look pdf)
Everything looks ok but, display is dead and no sound.
MIDI IN receiving DATA but MIDI out there is no DATA, PIC clock is 10mHz.
What is the magic way to work?
-
I fixed the problem "Received unexpected MIOS SysEx message = 00007E407001F7 expected = 00007E4002"
Was very easy the solution, "Upload Option" "Device Option" change to 70 for 18F4620
Midi input/output comunication is ok, but no sound, any ideia?
LCD is dead, this is an old one, will buy new LCD.
Thank for all inputs.

Manual mode, Delay 500, but LCD is dead.

Thanks for too fast answer but same problem here.
I have DSO 100mHz, pin 25 TX and pin 26 RX are OK

oh yes please more info... especially how you implemented the keyboard!
Fantastique!!!!
Could you share all schematics....especially how you implemented the keyboard!

Montei meu protótipo com placa universal, estou usando o PIC18F4620 comprei na Farnell, tenho um programador SmartProg2 e mandei bala programou 100%, agora só falta fazer o upload do MIOS, ai que começa o problema, meu PC não tem porta MIDI, andei lendo no forum e vou ter que comprar uma placa de audio com MIDI, minha pergunta é: Se eu tenho um programador profissional será que dá para gravar o MIOS direto sem o PC?

Construi meu primeiro sintetizador analogico quando tinha 17 anos, apresentei a varias bandas e todos davam risadas do som esquisito que fazia então abandonei a idéia, hoje tenho 50 estou abrindo minha empresa de projetos e tenho algum tempo para me dedicar a algum hoobie e este aqui foi um achado, simplesmente brilhante.
Tenho uma duvida em relação ao teclado, não vou usar midi vou fazer meu proprio teclado com chaves, já comprei um perto da Santa Ifigenia por R$40 , qual modulo devo usar e como calibrar as notas?
Tem muita informação aqui e ainda não deu para digerir tudo.
Core-reboot problem
in Testing/Troubleshooting
Posted
Hi!
It´s looks to be XTAL 10MHZ, C1, C2, if out of frequency or internal bad contact can reboot the CORE.
I hope this help you.
