hi to all...
actually i checked the communication is taking place via the rs232 cable. For that i installed the vcp driver and tried to communicate using the hyper terminal . badly , it wasn't communicating. i gave the 16(trans) and 17(rec) pins to the rs232 cable's corresponding rec and trans pins... and ground to 5th pin. why it is not communicating ?
pls help
definitely after.......u mean to say that communication not happening because of that improper connection i did ?
i did both com3 and com4...no response at all.
hi fvm
My module is FT2232HQ USB MINI MODULE.
I thoroughly checked by unplugging and plugging,those are the correct ports only.
And i connected a jumper on the cn3 1 and cn 3 pins (to make it as bus powered).
How about the VIO pins? Which RxD and TxD pins did you use? There are no respective pins like 16(trans) and 17(rec)?And i connected a jumper on the cn3 1 and cn 3 pins (to make it as bus powered).
Yes, these are the chip pins (AD0 and AD1). But which module pins did you connect?They have mentioned in the datsheet that 16 and 17 are rs232 transmit and receive pins .
Absolutely. AD0 (TxD) connects to pin CN2-7 and AD1 (RxD) to CN2-10. The bad thing with the FT2232H Mini Module datasheet is, that it doesn't mention the pin functions. So you have to read both in parallel, FT2232H chip and module datasheet.you mean to say that those are wrong
1) Connect VBUS to VCC (CN3, pin 1 to CN3, pin 3). This connection takes the power from the USB bus (VBUS) and connects it to the voltage regulator input on the FT2232H Mini Module. The voltage regulator, in turn, provides V3V3, VPLL and VUSB power inputs to the FT2232H chip.
2) Connect V3V3 to VIO (CN2, pins 1, 3 & 5 to CN2, pins 11 & 21 and CN3, pins 12 & 22). This connection provides the correct 3.3VDC operating voltage for VCCIO on the FT2232H chip.
u said the cn2 7 and 10 are the TX and RX pins . from where did you get this data ?
if possible could i have the link ?

sorry fvm
i didn't check the mini module's data sheet. i thought you got that from somewhere. sorry.
anyway thanks for your help
