The GPIO expansion is useful in any application for the number of GPIOs on a microprocessor is not sufficient. The relatively small numbers of GPIOs on microprocessors are becoming a limiting factor ...
Driving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Typically, designs perform this task by issuing pulse widths and clocks of differing durations and employing multiple ...
This application note explains how to use a microprocessor’s UART to implement a 1-Wire® bus master. It includes an explanation of the required electrical interface, UART configuration, and timing ...
Earlier this summer, a new development board hit the market that has proven itself to be a worthy contender against the legendary Raspberry Pi. The BeagleBone Black arrived on the scene back in April, ...
