MISO (Master In Slave Out)
makerMISO stands for Master In Slave Out, a signal line used for communication in Serial Peripheral Interface (SPI) protocol.
expanded
In the SPI communication protocol, the MISO line is the data line used for carrying output data from the slave device to the master device. It is a crucial part of full-duplex communication, allowing the master to receive data from the slave device while simultaneously sending data over the MOSI (Master Out Slave In) line. MISO is vital in systems where data integrity and timely response are critical, such as in sensor data readings and real-time data acquisition systems.
examples
The MISO line is employed in the BME280 environmental sensor for transferring sensor data to the microcontroller.
This configuration is commonly used in data logging systems for environmental monitoring where the BME280 sensor provides temperature, humidity, and pressure data.
In the use of the MAX6675 thermocouple-to-digital converter, the MISO line is used to transmit temperature data back to the master device.
This use case is standard in industrial temperature monitoring systems, where accurate and timely temperature readings are required from a thermocouple sensor.
