Hello I have worked on LPC3250 on Phytec 1305.3 board. I have a question about HSUARTs: Is there any difference between HSUART and UART regarding electrical interface? Is it possible to communicate a standard serial port with a high speed UART by adjusting serial port parameters? Thank you Alpaslan
The respective Datasheets will tell you that!
"Is it possible to communicate a standard serial port with a high speed UART by adjusting serial port parameters?"
By "standard serial port", I assume you mean the COM port(s) on a PC? Again, you will have to look at the specifications for your COM port(s) to determine what speeds they support.
I have some USB-to-Serial adaptors which support up to 921600 baud - I call that quite "high".
Note that a PC COM port must not be connected direct to any UART; you must use a suitable "RS232" transceiver - which must, of course, be specified for the maximum speed required...
