There are times when you don’t need much processing power for your project but you do need a lot of I/O pins. It often doesn’t make economic sense to choose a larger microcontroller just to get extra ...
This 8-bit I/O expander for the two-line bidirectional bus (I2C) is designed to provide general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL) ...
[Tech2077] is one of the lucky ones who already got his hands on a Raspberry Pi. He’s been looking into different interface options with the GPIO header and just posted a guide to using an HD44780 ...
Diodes has unveiled a 16-bit I/O expander, which enables any digital device to be accessed and controlled over an I2C interface, across a range of input and output voltages from 1.8V to 5V. The ...
An open-drain port expander for microcontrollers, the Catalyst Semiconductor CAT9552, is aimed at switching and flashing LEDs for advertising and industrial control. Data arriving through either an ...
