How to drive the Vinculum VDIP1 in UART mode

[circuitpro]

Thanks! Will do, and hope this VNc1L chip does it's thing!

Hi All. Totally agree with SkiMask RTFM policy, so made sure I scoured this forum, Googled, thoroughly read data sheets, and re-reviewed a lot of code available.

BrianT's code and explanation above is good, but still have a few questions....
I want to receive keyboard strokes to an 18F2550 via UART from a keyboard plugged into the VDIP1. When I press a key on the keyboard, does that automatically get forwarded to the UART interface on the VDIP1 and wait for transfer? Or, somehow do I need to tell the vnc1l that it needs to forward that keystroke to UART? Then how do I tell the VDIP1 to transfer each byte to the PIC serial port?

The code above focuses on sending data out to a disk on the VDIP1, but doesn't show how to get data back.... I think. Somebody point it out if I've missed something.

Thank you.
Kirt

Hi,

I am new here and as well as using VDIP1, I need it for my thesis prototype. I need help on how to reflash the frimware of VDIP1, I did these steps but i don't think something happens

1. I downloaded the latest firmware from vinculum, edit the filename of the file "ftrfb_main_3_68VDAP.ftd" to "ftrfb.ftd"
2. I copied the ftrfb.ftd to the root directory of my flash disk (PQI 512mb).
3. I made the circuit for the VDIP1 module:
3a. pin 1 to VCC (5V)
3b. connected pins 7 and 18 to GND
3c. pin 23 (PROG#) to GND
3d. I connected pin 22 (RESET#) into a reseting circuit that I made, There is a button that when pressed the output is low and when not pressed the output is high.
3e. I remove the jumper pins (both of them)
4. I inserted the flash disk to the VDIP1 module
5. Power the circuit, then press reset circuit to reset the module
6. Nothing happens.

I don't know if it is already reflashed or no, nothing is happening even the LEDs. I already e-mailed vinculum, but i haven't get any response for more than a week now. I really need the help, if you can, can you please give me a step-by-step procedure to reflash the module.

Thanks,
Bogs

Hey Bogs,

I am curious about your thesis. What is it about?

Hi Dave,

I can not share it right now, its a bit of confidential, not until of course after I finish it. I'll share it soon. Thanks a lot!

Best regards!
