SCK (Serial Clock)
makerSerial Clock (SCK) is a signal used in synchronous serial communication for timing data transmission.
expanded
In synchronous serial interfaces, such as SPI (Serial Peripheral Interface), the Serial Clock (SCK) is generated by the master device to synchronize the data exchange between the master and the slave device. The SCK oscillates at a set frequency to ensure that data bits are shifted in and out of the communication line accurately, making it crucial for applications where precise timing is necessary, such as microcontroller communication with sensors or memory devices.
examples
In an SPI communication setup with a microcontroller and an EEPROM, the SCK line transmits data at 1 MHz.
Commonly used in embedded systems, such as Arduino-based projects where data storage or logging is required.
An SPI-based TFT display module receives image data from a Raspberry Pi with an SCK frequency of 10 MHz.
Utilized in hobbyist projects and industrial control panels to provide real-time graphical data representation.
