ESP32 dev board from Az-Delivery. soldered on a dev breadboard with some wires to a MAX3232. Both devices are socketed to the breadboard for easy replacement. When not connected to the computer (99.9% ...
An Arduino sketch for translating a network connection to an RS232 connection at 300 baud, for a slow typewriter (Brother EP-22) If you are having a dumb terminal, and in particular a hardcopy ...
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 ...
Abstract: The purpose of this paper is to outline a universal RS232-to-GPIB interface which can enable a computer with an RS232 serial port to be a GPIB Talker or GPIB Listener and has the capable of ...
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 ...
