thank you mackrackit
soh it means only 1 firmware can be loaded for every VNCL IC
for my project that IC to transfer a files and i will put an LCD how can i acmmunicate that it is not easy to put a program on PIC rigth? any way
how can i use the PIC microcontroller and VNCL IC?
how they can communicate?
for VNCL firmware i know it has a free defined commands like in VDFC firmware
how can i control that commands if I use PIC microcontroller?
for example i use PIC18F458 how can i configure the output pins of the pic?
since the VNCL can accept the FIFO, UART or SPI. what is the examples codes for the pic like if i use picbasic commands? can i write the codes to manipulate the commands of VNCL but how can i control it to the pins of PIC microcontoller?
thanks, , ,

Up in post #4 I gave you a link showing how to WRITE to the VDIP1.

Here is the code from a project where I am READING from the VDIP1.
The VDIP1 part looks a lot like the writing example from BrianT. I used his same methods.

You should be able to connect two VDIP1s to the same PIC and with a little imagination do the copy.

Have you progrmed a PIC to do anything yet???

guys...what compiler do you use for this code posted above by mackrackit?

[mackrackit]

I use Pic Basic Pro for the compiler and MPASM for the assembler.

[newbie]

thanks for the quick reply...

are these compilers and assemblers downloadable for free? i can only find a demo version and it is just capable of compiling 30 lines.

could you please give me the procedure on how to program the vinculum(vdip2) using pic microcontroller? i'm kind of confused. will the command set of the vinculum be included in the program that will be burned to the pic just like in the code above? i'm new at this so please help me...thank you very much.

[mackrackit]

Everything is free except PicBasicPro.

This sounds like a first project for you. Start with someting like blinking a LED at the push of a switch... Then come back to this, but up in post #4 there is a link showing how to write to the module.

[newbie]

you are right, this is the first project for me, so i'm really starting from scratch. ive seen post #4 but i have one question, what will i do with that code after compiling it, whats next? will i burn it to the pic? i really need your answer on this to start. thank you.

[arunkumar]

i am doing in vinculum ic project..i want to copy the files as well as view the pen drive content on LCD display.. i bought VDIP2 modules.. we inserted rom files 3.66...if it possible reply sir....we are using pic to interface with VDIP2....

reply as soon as possible.....
