SPI is a kind of high-speed, full duplex, synchronous serial communication interface, and is used for connecting microcontroller, sensor and storage device. This text takes fingerprint identification module as the example to briefly introduce the use of SPI. SPI working mode¶ SPI works by maste...
Unlike the full-duplex, 3-wire serial interface, the I2C standard established by Philips communicates in half-duplex mode over one data line (SDA) and one control line (SCL). The I2C standard defines a simple master/slave bidirectional interface. In this scheme, the microcontroller designates wh...
SPI Communication with PIC Microcontroller – MPLAB XC8 SPI(Serial Peripheral Interface) is a full duplex synchronous serial communication interface used for short distance communications. It is usually used for communication between different modules in a same device or PCB. SPI devices communicates each...

It allows the microcontroller to communicate with serial peripheral devices and is also capable of interprocessor communications in a multi-master system. A serial clock line (SCK) synchronizes shifting and sampling of the information on two independent serial data lines. DSPI data is simultaneously ...
4.1 SPI modes These devices can be driven by a microcontroller with its SPI peripheral running in either of the following two modes: • CPOL = 0, CPHA = 0 • CPOL = 1, CPHA = 1 For these two modes, input data is latched in on the rising edge of serial cloc...
