Can Pull-up Resistors Be Used on SPI Lines?

The SPI (Serial Peripheral Interface) is a widely used synchronous communication protocol in embedded systems, commonly applied for communication between: Microcontrollers (MCUs) Sensors Memory devices ADC/DAC converters Display controllers Communication modules Unlike protocols such as I²C, which use open-drain signaling and require pull-up resistors by design, SPI typically uses push-pull drivers. This leads to a...
