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 ...
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 ...
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 ...
Handheld devices including smartphones and Tablet PCs have touch screens and many buttons for different functions. In order to save battery power, if the screen is not touched or the button is not ...
In system applications where various input signals are monitored or several output signals are controlled, these lines are sometimes connected directly to the microprocessor pins. Such monitoring and ...
Forty years ago today, electronics and semiconductor trade newspaper Electronic News ran an advertisement for a new kind of chip. The Intel 4004, a $60 chip in a 16-pin dual in-line package, was an ...
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, ...
