A logic analyzer is an electronic instrument that captures and displays multiple signals from a digital system or a digital circuit. It is an excellent tool for verifying and debugging digital designs. A logic analyzer may convert the captured data into timing diagrams, protocol decodes, state machine traces, and assembly language. For debugging elusive, intermittent […]
Introduction Embedded development has many activities like board bring-up, device driver development, RTOS or kernel bring up and finally giving the board to the application team for further development. An embedded engineer spends close to 40% of the time debugging the development work. Most of the firmware development gets debugged only after the board is […]
Debugging design in embedded systems is quite complex and Logic analyzers play a very important role to expedite the debugging and development cycle. Logic analyzers have a large number of channels that allow engineers to acquire many signals by connecting to a variety of test points on the DUT. Connections from the DUT to the […]
An eMMC Protocol (embedded Multi-Media Controller Protocol) Flash device is a non-volatile, rewritable mass storage device. Both flash memory and controller are included in a single integrated circuit. An eMMC Protocol acts as the dominant storage technology for mobile phones, automobiles, and PDAs. An eMMC memory device is used as an embedded storage device choice […]
WHAT IS TRIGGERING? The triggering feature allows engineers to capture a particular event of interest or data. Logic analyzers can be triggered on a variety of logical (Boolean) conditions. The purpose of the trigger is to select data to be captured by the logic analyzer. Logic analyzers can keep track of DUT logic states and […]
SDIO Protocol is a widely used Bus for the interfacing modem (device) to the application processor (Host). SDIO Protocol is used for Data exchange between host and device. Initially, the SDIO Protocol bus used operates at 50MHz (SD2.0) Specification. The current generation system uses a 200MHz (UHS I) SD3.0 bus. Like SD, SDIO Protocol capable […]
Difference Between I2C vs SPI What is I2C Protocol? I2C stands for Inter-Integrated Circuit. I2C is a simple two-wire serial protocol used to communicate between two devices or chips in an embedded system. I2C has two lines SCL and SDA, SCL is used for clock and SDA is used for data. What is SPI Protocol? […]
Overview of I2C Bus: The I2C’s physical two-wire interface consists of a bi-directional serial clock (SCL) and data (SDA) lines. Each device that is connected to the bus is software-addressable by a unique address and a simple master/slave relationship with the bus exists all the time. I2C is a serial, 8-bit oriented, bi-directional data transfer […]
Introduction to I2C Bus: I2C stands for Inter-Integrated Circuit. Philips Semiconductors developed I2C in the early 1980s as a low-cost solution for connecting lower-speed peripheral ICs to processors and microcontrollers over short distances. Since then, I2C has evolved into a worldwide standard for communication between devices in embedded systems. The simple two-wire design can be […]
I2S Protocol Introduction Today’s digital systems – from the Digital TV in the living room, Alexa, and google home for playing music and switching from text-based search to voice-based search– are driving convergence on many fronts. Quality of Experience is taking center stage. Audio requirements in Computers, Mobile Handsets, and Home Automation products have changed […]
