DESCRIPTION
We are quite familiar with seven-segment displays. We see them on our alarm clocks, ovens, and microwaves. By adding more segments to each digit you can display more than just numbers! These fourteen-segment digits allow you to display all sorts of numbers, characters, and symbols. With Qwiic, simply plug it in and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required!
我們對七段顯示器非常熟悉。我們在鬧鐘、烤箱和微波爐上看到它們。通過為每個數字添加更多段，您可以顯示的不僅僅是數字！這些十四段數字允許您顯示各種數字、字符和符號。使用Qwiic，只需將其插入即可。無需焊接，無需弄清楚是 SDA 還是 SCL，也無需電壓調節或轉換！
The SparkFun Qwiic Alphanumeric Kit comes with two displays, one red and one white. Also included in this kit are 10 standoffs and screws for mounting as well as two Qwiic cables to get up and running as fast as possible. With a wide variety of Qwiic enabled microcontroller boards available we decided not to include one so you could choose the one that fits best with your current project needs. This is the only part you need to supply yourself, so be sure to check the Hookup Accessories below for some suggestions!
SparkFun Qwiic 字母數字套件配有兩個顯示器，一個紅色，一個白色。該套件中還包括 10 個用於安裝的支架和螺釘，以及兩條 Qwiic 電纜，以便盡快啟動和運行。由於支持 Qwiic 的微控制器板種類繁多，因此我們決定不包括其中一種，以便您可以選擇最適合您當前項目需求的一種。這是您需要自己提供的唯一部分，因此請務必查看下面的連接配件以獲取一些建議！
The SparkFun Alphanumeric Display Arduino library makes printing strings to the display as easy as calling the print() function. With this library, you'll be able to send I2C commands to the VK16K33 LED driver chip to light up segments (including the decimal point or colon) and even scroll your string across the display. You can download the library through the Arduino library manager by searching 'SparkFun Alphanumeric Display' or you can get the GitHub repo as a .zip file and install the library from there.
所述SparkFun字母數字顯示屏的Arduino庫進行打印字符串到顯示一樣容易調用print（）函數。使用此庫，您將能夠向VK16K33 LED 驅動器芯片發送 I 2 C 命令以點亮段（包括小數點或冒號），甚至可以在顯示屏上滾動您的字符串。您可以通過 Arduino 庫管理器通過搜索“SparkFun Alphanumeric Display”下載庫，或者您可以獲取 GitHub 存儲庫作為 .zip 文件並從那里安裝庫。
The VK16K33 also supports I2C address configuration. Simply close a combination of the address jumpers on the back and you can communicate with up to four displays on the same bus. Our slim board design also features detachable standoff holes, vertical Qwiic connectors, and internal mounting holes.
VK16K33 還支持 I 2 C 地址配置。只需關閉背面的地址跳線組合，您就可以在同一條總線上與最多四台顯示器進行通信。我們的纖薄板設計還具有可拆卸的支架孔、垂直 Qwiic 連接器和內部安裝孔。
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
