It can be anywhere from 1 to 3 different labels in this case. Also helps to look at the block diagram on page 5. Page 21 explains the parallel I/O. Port A has 3 input and 4 output pins, Port B is an 8 ...

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 ...

A few articles have recently appeared describing novel ways to increase the number of LEDs a microprocessor can drive with a limited number of pins (Reference 1). The standard multiplexing technique ...

AMD CPUs are among the best processors around and suit all sorts of budgets, but they are a little different to their Intel counterparts. For starters, the pins are on the chip itself, rather than in ...

This idea builds on a previous IFD, "Connect Any Keypad With Any Microcontroller Using Only One Pin" (electronic design, May 1, 1998, p. 126), where a 555 timer connects a keypad switch matrix to a ...

On New Year's Eve der8auer published a video where he shared his analysis of the Coffee Lake controversy. In his signature style der8auer decided to look at the issue using a very hands-on approach, ...
