Discussion - Drivers / Re: issue related to UM232H eval. board

Hi,
thank you for previous  reply.



I am getting 60mhz clock. at ACBUS5 .

but the CLKOUT is triangular wave,peack to peack is 2.68 v. please check the attachment.


and please let me know what could be the problem ? how can I get square ?

why the voltage is too low. though operating voltage or supply voltage is 5V the output should be 3.3V.

Hi,
Thank you for the suggestions.
UM232H is generating 60Mhz clock.


But as I earlier mentioned, I have to interface this device with  FPGA, for this can you provide D2XX drivers in VERILOG/VHDL language instead of C++.

so that,UM232H device can be configured to synchronous fifo mode by setting Set_Bit_Mode=0x40 using ISE.

Can you provide us D2XX drivers files in VERILOG/VHDL, if available ?

sorry

from the TN_167 FIFO BASICS document I have chosen "Synchronous FIFO WRITE d2xx"   CODE.

hi,

 from the TN_167 FIFO BASICS document  i have chosen "Synchronous FIFO Read d2xx"  Example CODE and i have made the application on visual studio.

DONE.
device showing some values which are written in code.
but

 how can i get know the device is configured in 245 synchronous mode ?

and when and how 60Mhz clock will generates ??

thank you for the reply  :)


i have installed visual studio in my PC.

from the TN_167 FIFO BASICS document  i have chosen "Synchronous FIFO Read d2xx"  Example CODE and i have made the application on visual studio.
and started debug. in command window i have seen output as"0x0"
that i got to known device is in reset . so
 i powered on the device my device

then i again used debug option.
in command prompt window i got the values which are given in code.


with this i got to known that my device UM232H is detected and it is communicating with visual studio.



BUT, i have to use UM232H with FPGA. in my project .
i am transfering data from FPGA to UM232H. for FPGA i am using ISE.


my question is
1) how can i fix D2XX driver to work completely in synchronous fifo mode.
                                                           to use only ISE to for the transmission of data ?

hai,
 i am trying to use um232h eval board in sync fif0 mode.
 iam using windows7 64 bit.


In the document, 2.3 Synchronous FIFO I/O/page no: 8  Given that "Synchronous FIFO mode can only be accessed by the D2XX driver, with Bit Mode set to 0x40."



i have downloaded the cdm package.
and extracted from it. i am not getting any application software(.exe) to install he drivers.
i am getting .lib,.dll etc files

am i installed d2xx driver or not ?


but i am not getting how to change d2xx driver settings .


when i open D2XX.DLL file. i am not able to understand the code.

how and where the code need to change. ??
 
help me get a solution. ??
