Linux Device Driver Development For Beginners & Intermediates

Linux Device Driver Development from Ground-UP

Linux Device Driver Training using UDOO-NEO platform and NEEVEE Peripheral Shield with rich set of peripherals

Course focus on basic of linux kernel module, and then character drivers development, platform / miscellaneous driver development. Then it also used to explore General Purpose Input / Output Driver with Interrupt implementation, Inter integrated circuit, serial peripheral interface, industrial IO driver frameworks. Also provides hands on driver development for peripherals like light sensor, temperature / humidity sensor, LCD Display and etc.
