Click the blue text Follow us 1. Introduction to the I2C Bus The I2C bus is a serial, half-duplex bus introduced by Philips in the early 1980s, primarily used for communication between chips over short distances and at low speeds. The I2C bus consists of two bidirectional signal lines: one data line (SDA) for sending … Read more

Hello everyone, welcome to <span>Lixin Embedded</span>. In the field of industrial automation, Modbus is undoubtedly a name that cannot be ignored. As a communication protocol that originated in the late 1970s, it has stood the test of time, quietly supporting the interconnectivity of countless factories and devices. Today, let’s discuss Modbus, the veteran protocol of … Read more
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
