Embedded systems frequently use HD44780 -type LCD displays as it is considered the most popular alphanumeric display controller. The interface comprises at least 14 pins: eight for data, three for control (EN, WR, RS), two for power supply (Vdd, ...
.. by multiplexing [1-4] . A Some other Design Ideas use additional logic, which increases cost and size [5]. Figure 1. Two PIC pins drive six LEDs Note that VDD must be between 2V 3V: for example, if LED2 is ON (Table 1), LED4 and LED6 will ...
This project is pretty cool for a few reasons, and driving a huge LED matrix with a single 8-bit controller is just one of them. The idea was born when I bought 120 LEDs of the wrong type, and decided to do something with them. With that many LEDs, ...
Application Note TB3103 October 2013 Mihnea Rosu-Hamzescu This technical brief describes a synchronous buck power supply, based on the PIC16F753 using 100% analog control for output regulation. The implementation has the advantage of not using any ...
