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?

Can Anyone verify when you spark up a vdip module with 5v in fifo mode, attach an flash the led 2 will go on after the alternating led 1 and 2.

In my case this only happens for the uart mode which programming through hyper terminal/putty is fairy simple.

I require it in fifo mode though...

Thx

I have not tried FIFO and it looks like a waste of MCU pins to me.
Can I ask why you need to use that mode?

I also looked through the docs I have and did not see anything that would answer your question about the status LEDs.

Hi mackrackit,

I am actually using it with an fpga, but after a chat with the support guys in the US they said don't even bother with fifo on this chip its to flaky, rather stick to uart. FIFO will be upgraded in the 2nd gen ic VN2. So in the mean time i wrote a uart for the fpga and it seems to work.

Well I could not have done it witout the help of this forum.

Kind Regards

hi
can any one post circuit diagram to connect VDIP to PIC ??

read the comments in this thread. and download pdf files from http://www.ftdichip.com/index.html to gain more knowledge about the vdip...goodluck.

sorry about that., this is a better picture
