In this article, we will clarify how to build a bidirectional 2-bit mux circuit that can be used with I 2 C lines. The circuit also has the extra functionality of operating as a level shifter, if ...

Multiple Kickstarter project creator Doug Gilliland has now launched his 17th project via the crowdfunding website, offering a Raspberry Pi I2C Multiplexer for the small single board PC. The new piece ...

Adafruit has this week announced the arrival of the new Arduino compatible TCA9548A I2C Multiplexer to their online shop, which is now available to purchase priced at $6.95. The latest breakout board ...

从第一节到第九节（也就是这一节），说的都是ESP8266的基本应用，例如GPIO、定时器、中断、PWM等等。从后面开始，将陆续说一下基于网络的用法，毕竟这是个联网的芯片，还是要联网玩，才更能体现它的特点。但偶尔，我可能还会说一下它的硬件的基本用法 ...

I2C is a two-wire communication protocol known for its simplicity. Despite this reputation, I2C does have its challenges: a limited number of bits for a unique address can create address conflicts, or ...

If you’ve ever been laying out a network I2C devices inside a project box or throughout your robot’s body, you’ll probably know that I2C is not without its pitfalls. But for many of those pitfalls, ...

The HC-SR04 sonar modules are available for a mere pittance and, with some coaxing, can do a pretty decent job of helping your robot measure the distance to the nearest wall. But when sellers on eBay ...

The circuit shown can be used to interface multiple serial devices to the I2C bus, even if they lack the extended-addressing capability required. Information transfer be-tween I2C devices connected to ...
