SPI vs I2C

Developers should learn SPI when working with embedded systems, IoT devices, or hardware projects that require efficient communication between a microcontroller and multiple peripherals meets developers should learn i2c when working with embedded systems, iot devices, or hardware projects that require communication between multiple integrated circuits on a single board, as it simplifies wiring and reduces pin count compared to parallel interfaces. Here's our take.

SPI

Nice Pick

Developers should learn SPI when working with embedded systems, IoT devices, or hardware projects that require efficient communication between a microcontroller and multiple peripherals

Pros

• It is particularly useful for applications needing high-speed data transfer, such as reading from sensors, writing to flash memory, or driving displays, due to its low latency and straightforward implementation compared to other protocols like I2C
• Related to: embedded-systems, microcontrollers

Cons

• Specific tradeoffs depend on your use case

I2C

Developers should learn I2C when working with embedded systems, IoT devices, or hardware projects that require communication between multiple integrated circuits on a single board, as it simplifies wiring and reduces pin count compared to parallel interfaces

Pros

• It is ideal for scenarios where moderate data rates (typically up to 3
• Related to: spi, uart

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. SPI is a concept while I2C is a protocol. We picked SPI based on overall popularity, but your choice depends on what you're building.

The Bottom Line

SPI wins

Based on overall popularity. SPI is more widely used, but I2C excels in its own space.
