The project provides the conversion between an RS232 serial interface and an SPI interface which uses the SSP port on a 16F819 device. It is possible to send any sequence of bytes on the SPI interface ...

The project illustrates the use of bit-banging on a 12F683 device by the PS/2 interface which can come from the mouse or keyboard with the other side of PCB having RS232 serial interface while being ...

The typical RS232 transceiver interface IC found in many embedded systems generates ±6-V line-level signals. While these signals aren’t intended to deliver power, in certain situations it’s possible ...
