Embedded Linux Training Course Programming

Embisyslabs Embedded Systems Training Institutes in bangalore courses offered on Embedded Linux. Embedded Linux is the system of choice for many embedded systems such as smartphones, tablets, PDAs, set-top boxes, and personal media players. Any version of Linux used to operate such machines is known as Embedded Linux.

Weekend and Weekdays Training Courses on Embedded Linux

  • Why choose Linux for embedded linux development projects? .
  • Embedded Linux has limited memory and disc space and no external network. We have only two user interfaces LEDs and serial ports.
  • Platform Independent. (compiled on one platform and can be executed on any other platforms).
  • It allows unlimited modifications in the source code. i.e we can re use components multiple times.
  • Software is of free cost. Only budget considered for Hardware
