Can anyone help ?
I need a serial interface for a robotics project.I've searched the web and found only one circuit , but that uses a 6402 UART ic which I'm told is now obsolete.
in many parts catalogs there are a couple of chips called, PISO, or SIPO.
parallel in serial out and serial in parallel out. by making a clock that works at the baud rate you are looking for and deviding it by the number of bits in your serial stream , that will give you the clock rate you need to use the sipo. giving you serial to parallel. there are also many other ways.
on https://www.commlinx.com.au contains a schematic directory and in there schematic directory they have a design using an atmel microcontroller and uncludes code. so there are many options available.
