SPI Interface Serial peripheral interface (SPI) is a synchronous, full-duplex master-slave-based interface.The data from the master or the slave is synchronized on the rising or falling clock edge. Both master and slave can transmit data at the same time. The SPI interface can be either 3-wire or 4-wire.4-wire SPI devices…
This post is to explain the handling of GPIO interrupts in Linux with IMX6-SOLOX. I will use Udoo neo full development board which is based on NXP IMX6-SOLOX SOC. In Udoo neo full there are 32 GPIOs for user access. Out of 32, two GPIOs are connected to LEDs, and…
Device Drivers In Linux, device drivers acts as an intermediate between the user application and hardware.The device drivers expose the functionality of the hardware to user programs. In this post I am going to write Linux device driver for MCP9808 temperature sensor which is interfaced through I2C-2 bus with UDOO…
