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.
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.
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!)

4位7段顯示器真的是整潔的小設備,這是一個恥辱,他們可以如此繁瑣的控制。好了,我們已經通過他們一點點的解決了這個問題“更聰明。”該SparkFun 7段串行顯示結合了經典的4位7段顯示器和ATMega328微控制器,允許您控制單獨使用只有少數串行每段線。
串行通信TTL,SPI串行通訊或I2C串行:串行7段顯示器可以通過以下三種方式之一進行控制。由於ATMega328預裝與Arduino的引導程序,你甚至可以單機操作編程吧!還有船上的FTDI頭和我們提供的Arduino的IDE硬件配置文件,使之更容易編程。
我們已經做了一些佈局更改此設計,以及這將使其更容易融入到這些項目中。我們移動電源和I2C引腳連接到電路板的兩側,這樣你可以連在一起,以顯示較長的數字串。我們還添加了安裝孔的板,使您可以在支架安裝它們(沒有更多的熱膠!)
