Interrupts in Embedded Systems: From Hardware Events to Firmware Execution

Embedded Systems Fundamentals #5 Every embedded application relies on interrupts. Whether you're developing a UART driver, reading a sensor over SPI, handling an I²C transaction, servicing a timer, or

Why I3C Exists: The Evolution Beyond I²C

Embedded Systems Fundamentals #4 If you've worked with embedded systems for any length of time, you've almost certainly used I²C. It connects: Temperature sensors Accelerometers Gyroscopes EEPROMs

Understanding I²C From a Engineer's Perspective

Embedded Systems Fundamentals #3 If SPI is the protocol of speed, Inter-Integrated Circuit (I²C )is the protocol of simplicity. You'll find I²C everywhere: Temperature sensors Accelerometers PMICs

SPI Explained Beyond MOSI and MISO

Embedded Systems Fundamentals #2 Most engineers learn SPI through a simple diagram: Master ---- Slave MOSI MISO SCLK CS A transfer begins. Bytes move. The transfer completes. Simple. But inside the

What Really Happens When You Send Data Through UART?

Most engineers learn UART as one of the first communication protocols in embedded systems. We often see diagrams showing TX connected to RX, configure a baud rate, call a transmit API, and data magica
