When this is done, you will need to set up a terminal emulator program on your PC as described below. Other circuits for level shifting are shown at RPi. See this tutorial for an example using a ready- made level shifter module. These can be simply plugged in directly to the GPIO header (see illustration). 32 level converter with a breadboard, a MAX3. See this tutorial for one example on how to build a 3. If you wish to connect one of these, you need a board or adapter to convert the signal levels. You will also need to connect the Ground pins of the two devices together. To connect to another serial device, you connect the 'transmit' of one to the 'receive' of the other, and vice versa. ![]() The Raspberry Pi serial port consists of two signals (a 'transmit' signal, Tx. This can be useful if you want the Raspberry Pi to control another device. ![]() Connecting to a microcontroller or other peripheral which has a serial interface. ![]() This can help to fix problems during boot, or to log in to the Raspberry Pi if the video and network are not available. Connecting to a PC to allow access to the Linux console. There are two main ways in which it can be used. Simple C++ class example using serial port, USB, wireless.įor Spanish version click here Parallel port interfacing made easy: Simple circuits and programs to show how to use PC parallel port output capabilities.
