The link given up in post#3 tells all about writing data to the VDIP1.
For the programming part, does it work by just simply sending command through TXD to VDIP1? Any delays to be considered?
Do you mean for upgrading the VDIP1 firmware? Like I said before, the easy way is to have the new firmware on a flash drive. When the VDIP1 starts the firmware will be updated.
Can I have an example of PIC code to make VDIP1 perform data backup of flash drives to another flash drive?
Nope, I do not have such code.
We have added an external USB port for VDIP1, but we are just having problems with the programming. We've tried many codes that we wrote ourselves but most fails..
If you post your code we might be able to help you figure out what is wrong.
