What is LiDAR and how does it work?

Nikhil Agnihotri — Tue, 01 Nov 2022 23:57:35 +0000

LiDAR is an acronym for light detection and ranging, an optical technology for sensing distance. Early attempts to measure distance by light beams were first made in the ’30s, and airborne LiDAR became more commonly used in the ’60s, with geospatial measurements beginning in the ’80s. As the technology evolved, LiDAR’s uses continued to expand.…

Writing a bootloader for Arm Cortex-A35/A5X microprocessors

engineersgarage — Wed, 20 Jul 2022 22:00:03 +0000

By Aaron Bauch, Senior Field Application Engineer, IAR Systems Design specifications require the ability to update a device’s firmware in the field dynamically. This is done commonly via a bootloader. Designing a bootloader, however, is challenging as it must meet various requirements. For example, the mechanism for getting the new application into the MPU is…

An Embedded Developer’s Perspective on IOT (Internet of Things)

Vikas Gulia — Thu, 30 Jun 2022 12:09:21 +0000

Embedded device, Networked sensor and actuators form the ground for IoT. An Embedded developer look IoT (Internet of Things) as area full of opportunity. IoT is not limited to any particular domain or business. IoT involves all the device which have a unique ID and can be configured with address to locate them. For An embedded developer IoT is not just limit to a single area, an embedded developer can design, develop & program, configure, debug and reprogram any device.

What is an embedded system?

Preeti Jain — Wed, 16 Mar 2022 10:50:07 +0000

If we look around, we will find ourselves to be surrounded by computing systems. Every year millions of computing systems are built destined for desktop computers (Personal Computers, workstations, mainframes and servers) but surprisingly, billions of computing systems are built every year embedded within larger electronic devices and still goes unnoticed. Any device running on electric power either already has computing system or will soon have computing system embedded in it.

FPGA vs microcontrollers: Another approach to embedded design

Engineers Garage — Mon, 17 Jan 2022 14:06:52 +0000

Most engineers start their journey in embedded systems with microcontrollers. With microcontrollers, one gets a complete miniature computing system on a single integrated circuit. The CPU, RAM, ROM and Input / Output peripherals all on a single thumb size SoC. This very popular approach to learning embedded design and development is in fact just the one side of the complete picture. Working with microcontrollers (and microprocessors) is all about software-based embedded design.
