This application note describes the operation of a general- purpose, microcontroller-based Serial Port Interface (SPI) boot circuit. This is a low cost solution for users who need to modify some of ...

16-button keypads have a clever method of encoding their data into 8 pins. Pins are mapped to four rows and four columns on the keypad. A user reads the keypad by bringing each row up to logic: HIGH, ...

The programming of Philips Bridge ICs such as SC16IS750 through SPI-bus is discussed in this application note. In addition, the source code in C language, containing SPI communication routines between ...

Electronic enthusiasts, makers and hobbyists searching for a small three or five megapixel camera to use with their next microcontroller project may be interested in the Arducam Mega. Designed to ...

Serial Peripheral Interface (SPI) is not really a protocol, but more of a general idea. It’s the bare-minimum way to transfer a lot of data between two chips as quickly as possible, and for that ...

For certain applications, the use of a low-cost microcontroller (MCU) is a must, yet many of those applications need to interface with high data rate signals. The problem is that as the data rate of ...

NXP is delivering a unique ARM-based Cortex-M3 microcontroller that can run off serial QPI flash memory as just one of its features. The on-chip flash supports dual bank operation and simultaneous ...

It even has procedural tracks.
