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, ...

Although 8051-compatible microcontrollers with SPI ports are available, a lower-cost device with an SPI port bit-banged through GPIO pins often suffices. The code shown here takes advantage of ...

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 ...

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 ...

Using an isolated serial peripheral interface (SPI) bus can be a challenge when dealing with higher speeds. Find out what the limits are. The serial peripheral interface (SPI) bus is a synchronous, ...
