A bootloader banner on a tiny monochrome panel, a Qt dashboard on a 10.1 inch industrial HMI, a marine chart under direct sunlight, a medical monitor where grayscale precision matters, an EV cluster that must boot quickly and never flicker, a battery IoT node that should run for months: all of these are “just displays” until they fail in the field. This guide is for embedded software engineers, Embedded Linux developers, hardware engineers, and advanced electronics enthusiasts who need technical clarity, not marketing language.https://toorun.dev/posts/communication-protocols-and-interfaces-explained-spi-i2c-uart-usart-can-ethernet-usb-rs232-rs485/Sun, 21 Jun 2026 10:00:00 +0000https://toorun.dev/posts/communication-protocols-and-interfaces-explained-spi-i2c-uart-usart-can-ethernet-usb-rs232-rs485/Communication Protocols and Interfaces Explained: SPI, I2C, UART, USART, CAN, Ethernet, USB, RS-232, RS-485 and More Modern electronic systems are distributed systems. Even a small product can include a microcontroller, sensors, power-management ICs, memory, a wireless module, and a gateway to cloud services. None of those blocks are useful in isolation. They must communicate. This guide is for engineers who want practical understanding, not only textbook definitions. You will find side-by-side protocol comparisons, real-world selection advice, interview questions, and production-focused best practices.https://toorun.dev/posts/s19-motorola-s-record-file-format-guide/Sat, 13 Jun 2026 10:00:00 +0000https://toorun.dev/posts/s19-motorola-s-record-file-format-guide/S19 File Format (Motorola S-Record): Complete Practical Guide for Embedded Firmware and Bootloaders Suggested title: S19 File Format (Motorola S-Record): Complete Practical Guide for Embedded Firmware and Bootloaders Suggested meta description: Understand the S19 file format used in embedded firmware updates and automotive ECU programming.
