[help help help  !! with JDM]

:D :D :D :D

;D ;D ;D ;D

ITS WORKING !

YIPIKAYEY !!

i managed to program it with : direct i/o and delay = 2

i came to a conclusion that my jdm is fine so i started playing with the "method" (api vs. i/o) and "delay" !

tried alot of combinations untill i've found this (working) one, and again :  ;D ;D ;D ;D

weird thing is when i tried a different .hex file with the same settings and same pic - it failed !!

thank you all for your support !

see u on the other side of this forum

[help help help  !! with JDM]

Progress ?? maybe…

On the same jdm I managed to program a pic18f452 !!! I burned only the “bootstrap loader†into the pic…NO PROBLEMS at all – programmed and verified !! (cant check if its working ‘cause I have only a MidiboxPlus).

Does this mean that my jdm is healthy ?

But still… cant burn the 16f…

It is a pic16f877-20/p ! not A !

I got the .hex files from the MidiboxPlus page – it  is version v1910 !

I reseted my settings of Icprog and started all over – same result !

The chip is being programmed but only until line 0420h ! then it fails !

Could this be a bug in the .hex file ?? when I load it into Icprog I get a message “the file does not contain a device ID valueâ€

Is there an other .hex file for pic16f877 .. only to see if its working ?

What could be wrong

H-E-L-P

[help help help  !! with JDM]

I m SO frustrated !!

I have vicious thoughts about throwing it all away !!

:'( :'( :'( :'( :'(

PLEASE HELP !!

I m trying to burn a pic 16f877 for a MidiboxPlus with 8 knobs (I know its old).

I got the pcb from “SmashTv†and the parts as well, soldered everything and checked it infinite times >> it is perfect… every part in its place and at the correct direction !

Icprog (version 1.05c) is on “Windows API†…. “I/o delay†= 1 (no influence anyway)

I even have the two 9v batteries connected !!

Here are my readings :

Mclr = 13.4

Vcc = 5

Clock = 5.7

Data out = 4.5

With the pic in the socket readings are :

Mclr = 13.4

Vdd = 5

I am able to read and erase !!

Now, when I load the .hex file Icprog says “the file does not contain a device ID valueâ€

Then when I try to program it Icprog says (after about 15sec of programming) : “programming failed at code address 0420h†!!

Then when I read the pic I does have info in it but it stops at line 0420 !!

I tried to program a brand new pic as well as an erased pic, tried on two machines one with xp other with 98, every time same results

PLEASE HELP

[a new jdm programmer]

HELLO !!

i see many-too-many people (including me) having problems with the jdm programmer, it seems to be the most problematic part of midibox !!

it got some neverending problems !!

so --->  ;D ;D ;D

why not trying to build an OTHER solution..

a different programmer

[JDM issue solved?]

and what about the "pre-flight-check" ??

should i do it as on the site and get the same results ?

or is it different now ?

is the change good for all the other pics ?

[a new (???) idea]

u may look at the MIDIOX mapping window, it is very easy to use and understand !!

(i wish i had the knowledge to do this myself)

[a new (???) idea]

hey Thorsten, check this ^^^ out !

it seems we have a winner !

could u ? pliz ?

CALLING ALL PROGRAMMERS, or whoelse that got the knowledge to help.

(because i dont know shit about this, i ask for your help)

there is a topic here named "a new (? ??) idea" - it is about more friendly programming of the Midi Filter !!

the one who'll take this task (and succeed) is guaranteed to be taken to greatness and get into the hall of fame. :D

please take a look and see if u can help !

[a new (???) idea]

WOULD SOME ONE DO IT ?!

CALLING ALL PROGRAMERS !!!

who will be the genius that (in the name of the knowledge-sharing) will take this task on him ?

[a new (???) idea]

OOPS... SORRY

i  guess i wasnt looking good enough !

as i see it - it seems kinda complicated to "program" to mapping of this device.

there must be an easier way to do this, so me too (no programing skills) can do this.

the MidiOx mapping i understand, this midifilter maping - i do not !!

i think its a good idea to try and enhance this machine so it would be more friendly to program, and also i think it should have some memory-bank

[a new (???) idea]

jah people

as i know NOTHING about electronics i will tell you knowledgers my idea -

a device that functions as a midi converter !!!

what i do today is using midiox to convert one event to another, say NRPN to control, say convert chanel 1 to chanel 2 etc.

i know its possible because i see it on one site (dont remember the address).

this not only for midibox but for other device as well - the principal is that it will be possible to control equipment "on the run" without the need of a computer.

i've found the web, it is here : http://www.midisolutions.com/prodmap.htm

(the right word for it is MAPPER !!!)

and maybe its possible to implement several "memories" into it, like the bank-switch.

[how do you make the GRAPHICS ??]

how do you do those labels = GRAPHICS = on your boxes ??

i see people writing and "graphicing" on their boxes with their own design and colors..

is it printed with a home-printer or, in some way, directly on the surface ??

how can i do this if i got a wooden box and a plastic box

[JDM PIC programmer HELP!!!]

is this one  different ???

it is not the same as the scematics shown on the site...where are the zeners ??

[HELP with jdm]

i disconnected the BC547C and checked it with a multimeter that got a "transistor-checkin-socket".

my result was "012" !

does this mean good or bad news ??

[HELP with jdm]

weird things going on !!

first - thank you for all the help !!

trying to narrow the problematic area, those are my measurments :

- enable mclr is on

- disconnecting from D4 i get 11.9v from GND to #3,so far so good

when i solder it back on i get from the same point 2.1v !! (a discent bad-word should b here)

- D4 is good - checked and replaced

 on its "-" i get 2.1v, on its "+" i get 1.6v

- on Q1 i get 1.6v on both C and E ,on B i get 2.1

- on D3 "-" i get 2.1v, on its "+" i get -4.7v

everything with respect to GND, the "-" on it.

(are we having any progress at all ?)

[HELP with jdm]

PAFFFF !

detz some inside information, when i'll have the time i'll go deep in there...

right now i just want it working as fast...

here are my results :

- "Enable MCLR" = on

- my "+" probe on the GND

(i m looking on the JDM circuit that is on the "ucapps.de")

- on D1 "-" (the side with the | ) i get 5.6v

 same on D2 "+"

- on D2 "-" i get 0v !!

- on D1 "+" i get 4.8v

- on D6 "+" i get 4.8v

- on D6 "-" i get 0v !!

- on D5 "+" i get 0v !!

- on D5 "-" i get -1.6v

WHAT IS WRONG ??

H E L P :'(

[HELP with jdm]

i've found a strange thing :

when i put my "-" probe on the #5 (GND) and the "+" probe on #7 (RTS) my friendly multimeter shouts : -5.5 !

this means the current is inverted !!

and this means..

that my #5 is my "+" and the others ( #3,#4,#7,#8 ) are my "-"

is this the way it suppose to be ? my (little) knowledge in electronics tells me it is INVERTED.

[HELP with jdm]

(well now i m in the "troubles" section  :-[ )

i've built the jdm on a protoboard and used a 8.2v zener, and the capacitors are of 25v !

BUT THE DAMN THING IS NOT WORKING !

my tests show :

- "enable mclr" = 6.4v

- "enable vcc"  = 4.7v

- "enable clock" = 0v (?!)

- "enable data out" = 4.3v

i tried it on 3 diferent COMs, its all the same.

the i/o delay dont have ANY influence at all.

please P-L-I-Z   HELP

[what does it mean ?]

THANK YOU VERY MUCH !!

are those good for the JDMprog ??

[what does it mean ?]

on my zener diode is written : "1N_47_33A_821" does this mean its a 8.2v ??

on my other zener diode is written : "1N_47_38A_604" what does it mean  ??

this is crucial because ALL my voltage measures on the JDMprog are oh-so-wrong !!

[need help with parts]

hello again...

i ordered the parts for MidiBox8+JDMprogrammer but some of them are not exactly as i ordered, please take a look at this and tell me if i can use those  :

- ALL the el.capacitors are 25v (except for the 2200uF for the power supply - it is 16v).

- the "74hc00" is a "74hc00p"

- the "cny17-2" is a cny17-1"

- the "bc547b" is a "bc547c"

- the 8.7v zener doide is a 8.2v

tell me if its ok to use them or not - or should i do any changes  ???

[a dial instead of the toggles]

is is possible to use a dial-selector with 16 positions instead of the 4 toggles, in order to select a bank - i think it more convenient using a dial/selector.
