Re: LF: Links?
[Prev][Next][Index][Thread]
Flow control can be achieved using a UART chip. You just have to convert
the serial data coming out of the TI to parallel first to use the UART. I
know it sounds a little crazy changing serial to parallel and bach to serial
again, but that's the only way I can see to get the flow control. The
signal out of the UART would be the same as the signal from the RS232 (
RS232 gest it's signal from a UART. )
