SPI (Serial Peripheral Interface) is one of the most widely used interfaces between microcontrollers and peripheral ICs (such as sensors, ADCs, DACs, shift registers, SRAM, etc.). SPI is a synchronous, serial interface. Data from the master or slave is synchronized on the rising or falling edge of the clock. A common 4-wire interface is shown … Read more
A common misconception is that pull-up resistors are always required on SPI bus lines. I want to make it clear that pull-up resistors are not always necessary for the basic function of sending and receiving digital data on the SPI bus. The buffers in the SPI interface use a push-pull topology, which involves high-side and … Read more
Today, we will introduce the widely used SPI communication between PCB boards, striving to minimize the introduction of overly textual definitions and instead use straightforward language to explain. Definition: SPI (Serial Peripheral Interface) is a type of serial synchronous communication, which is mostly full-duplex (but it can also be half-duplex), primarily used in chips such … Read more

1. Introduction: When the “Two Wires” Suddenly “Stop Working“ In the daily work of embedded engineers, the I2C bus, with its two-wire communication feature, is a prime example of “minimalist aesthetics“. However, this seemingly simple two-wire system can suddenly fall into a “deadlock“—the clock line (SCL) stubbornly remains high, while the data line (SDA) is … Read more
