QSPI Introduction QSPI stands for Queued Serial Peripheral Interface, an extension of the SPI interface introduced by Motorola. QSPI has wider applications than SPI due to the enhanced functionality provided by Motorola, including the addition of a queued transmission mechanism. This led to the development of the Queued Serial Peripheral Interface Protocol (QSPI protocol) based

Preface I2C has two different modes of operation: master and slave mode. In most cases, when controlling sensor MCUs, the master mode is used for operation. Some EEPROMs may require the MCU to operate as a slave. However, when using the slave HAL, a known length is required for normal operation. Here, we will introduce

Preface I2C Bus, like SPI, is also a master-slave architecture, but it differs from SPI’s point-to-point or point-to-multipoint structure. It uses a bus structure, allowing multiple masters and multiple slaves to be connected to the bus at the same time. The most important component of the I2C Bus is its pull-up resistors. However, many people
