FT232 can provide at least full througput with VCOM driver and 920kBaud, or up to 1 MByte/s with native driver. It's most likely a problem of inappropriate API interface usage at the PC side.
The software is written in VB using mscomm object.
The same is running at full speed with prolific based converter.
Yes i do feel that the driver is the problem
FTDI web site says the chip can drive upto 3Mbytes.
I had asked help from FTDI website, still now i did'nt get any reply, iam waiting for that
Can u help me to get any driver other than the one supplied by FTDI
I'm always using FTDI drivers, but through generic windows API with C++ or Delphi. Did you try to adjust the advanced port settings for the device in system control manager? Also using the FTD2XX driver interface generally achieves higher speed than VCOM.
A made a communication with FT232R and Atmega8 on 16MHz. On PC, there was Labview. 1Mbit/s wasn't a problem at all. And there is maximum speed 3Mbits/s and not 3Mbytes/s - that's the big difference. You must use updated d2xx drivers.
sir,
my project name is smoker's counselor we are using 89C52 micro controller.
it has 3 blocks 1.smoke detector 2.lcd interfacing 3.audio output.
when smoke comes it will detected by the smoke detector and a message like QUIT SMOKING will displayed in the lcd and same will come through audio output.
so here when smoke comes then only lcd is displaying message otherwise it is just neutral now i want the lcd to work for no smoking condition.
so Iam now interfacing DS1307rtc to the 89C52 so that it will display the time and calender when there is no smoke .
actually i don't know how to interface rtc the 89C52 can any one suggest me how to do this.
plz give the C code for this .
