Hi all
I urgently need an RS232 discrete component ckt. that can read 100kilobytes of data at one go w/o corruption. could somebody please help me out??
Generally, any RS-232 interface IC will work up to 115.2 kbps. So I don't see the problem there.
Perhaps you are dealing with long cables? If that is the case, then you may have to reduce the baud rate.
Another possible problem may be in the RS-232 UART, if the clock is not accurate. Finally, you should make sure that the micro has enough "horsepower" to receive all the data without overrun errors. In fact, you should look at the type of errors you are getting in the current implementation. They should provide clues as to what is happening. For instance, if you get many parity errors, then you can say that probably there is too much noise on the line, or the line is very long and the baud rate should be dropped. If you get many framing errors, then you should question the UART's clock. But if you get overrun errors, then the transmission is doing OK, it's just that the micro was not fas enough to read out all the data (buffer too small?).
hi
thx for ur reply. I m basically designing discrete component ckt. consisting of opto diodes and opto transistors for level translation. In that I need the mentioned performance. I can give u the ckt if u want it . DO anyone of u have a working ckt. for the same purpose?? If u have could u please let me have it to try it out.
