Sparkfun原廠 7-Segment Serial Display串行顯示 - Red紅(COM-11441)
Product Overview 產品概述
4-digit 7-segment displays are really neat little devices, it's a shame that they can be so cumbersome to control. Well we've solved that problem by making them a little bit "smarter." The SparkFun 7-Segment Serial Display combines a classic 4-digit 7-segment display and an ATMega328 microcontroller allowing you to control every segment individually using only a few serial lines.
4 位元 7 段顯示器確實是精巧的小設備，可惜它們的控制卻非常麻煩。我們透過讓它們變得更「聰明」一點來解決了這個問題。 SparkFun 7 段串列顯示器結合了經典的 4 位元 7 段顯示器和 ATMega328 微控制器，讓您只使用幾條串列線即可單獨控制每個區段。
The Serial 7-Segment Display can be controlled in one of three ways: Serial TTL communication, SPI serial communication or I2C serial. You can even program it for stand-alone operation since the ATMega328 comes pre-loaded with the Arduino bootloader! There is also an FTDI header on board and we've provided a hardware profile for the Arduino IDE to make it even easier to program.
串行 7 段顯示器可以透過以下三種方式之一進行控制：串行 TTL 通訊、SPI 串行通訊或 I2C 串行。由於 ATMega328 預先安裝了 Arduino 引導程序，您甚至可以對其進行編程以進行獨立操作！板上還有一個 FTDI 接頭，我們為 Arduino IDE 提供了硬體配置文件，以使其更易於編程。
We've made some layout changes to this design as well which will make it easier to incorporate these into your project. We've moved the power and I2C pins to the sides of the board such that you can chain them together in order to display longer strings of digits. We've also added mounting holes to the boards so you can mount them on standoffs (no more hot glue!)
我們也對該設計進行了一些佈局更改，以便更輕鬆地將其合併到您的專案中。我們將電源供應器和 I2C 引腳移至電路板的兩側，以便您可以將它們連結在一起以顯示更長的數位串。我們還在電路板上添加了安裝孔，以便您可以將它們安裝在支架上（不再使用熱膠！）
