我最近不得不冒险进入阁楼解决浴室通风口问题，并重新发现了我存放的绝缘和灰尘覆盖的电子盒。
刮掉它并把它带到我的实验室检查，我意识到我忘记了...
在这里约会我自己，但是在1983年进入微处理器并且攻击我的旧CoCo计算机（以前称为彩色计算机，最初有4k但我升级到16K☺，LOL）的日子，当我打开盒子时再次活跃起来
。
它带来了令人兴奋的冒险，即使用旧的摩托罗拉6809制作实际的电脑板，学习汇编语言，并使用绕线针和穿孔板来创建它。
将带状电缆焊接到卡边缘连接器下方的母板，可以访问端口的计算机板的i / o线。
我在一个名为EDTASM的程序中编写了汇编语言，并使用了一个5¼英寸的软盘驱动器来运行该程序。
使用编程器板将我的已组装程序刻录到EPROM，然后我将其插入计算机板以进行测试，在那里我尝试使用步进电机来运行自制绘图仪。
随着技术和嵌入式世界的发展，事情变得越来越好。
我在1984年被Digi-Key聘用来支持一个名为DB10板的热门产品，它是美国国家半导体的一个小型基本电脑板，它使用CRT（阴极射线管或类似小电视的终端）和键盘来编写基本版本。
编程语言，您可以轻松访问外围适配器IC并输出到晶体管驱动器，以驱动步进电机，照明LED或向LCD点阵显示器发送消息。

再次，随着技术的发展，微控制器被创建。
它基本上组合了微处理器系统的所有区域 - 即微处理器，地址解码，静态存储器，程序存储器，外围接口适配器IC，振荡器和电容器。
摘自Digi-Key目录
在90年代早期，我们使用Parallax公司的廉价编程器添加了PIC系列微控制器（那时它是我们客户成本最低的编程器）。
出现在600多万份目录中，这种独特的组合飙升了MCU的销售和革命。
从那时起，今天我们增加了大量的开发板（产品索引）和MCU供应商。
仅举几例，Arduino，Raspberry PI和Beagle Bone都非常受客户欢迎。
为了简化查找板，我们创建了“开发工具产品选择器”指南。
当您考虑技术如何从第一台传真机，互联网，微处理器到微控制器，手机，物联网，3D打印和人工智能发展时，您必须要问：在这些激动人心的时代的演变中，下一步是什么......一颗星星

I recently had to venture up into my attic to solve a bathroom vent problem and rediscovered my stored away box of electronics covered in insulation and dust. Scraping it off and taking it down to my lab for inspection, I realized what I had forgotten about…
Dating myself here, but the days of getting into microprocessors back in 1983 and hacking my old CoCo computer (formerly known as The Color Computer which originally had 4k but I upgraded it to 16K ☺, LOL), came alive again when I opened the box. It brought out the exciting adventure of making an actual computer board using the old Motorola 6809, learning assembly language, and using wire wrap pins and a perf board to create it.
Soldering a ribbon cable to the mother board under the card edge connector gave me access to the port’s i/o lines for my computer board. I wrote assembly language in a program called EDTASM and used a 5 ¼ inch floppy disk drive to run the program. Using a programmer board to burn in my assembled program to an EPROM, I then inserted it to the computer board for testing where I experimented with stepper motors to run a homemade plotter.
As technology and the embedded world evolved, things kept getting better. I was hired by Digi-Key in 1984 to support a popular item called the DB10 board, which was a tiny basic computer board from National Semiconductor that used a CRT (cathode ray tube or terminal which resembled a small TV) and keyboard to write basic programming language where you could easily get to the peripheral adapter ICs and output to a transistor driver for driving stepper motors, lighting LEDs, or sending a message to a LCD dot matrix display.

Again, as technology evolved, the microcontroller was created. It basically combined all areas of a microprocessor system - i.e., microprocessor, address decoding, static memory, program memory, peripheral interface adapter ICs, oscillator, and capacitors.

In the early 90s we added the PIC line of microcontrollers with an inexpensive programmer from Parallax Inc (at that time it was the lowest cost programmer for our customers). Appearing in over 6 million catalogs mailed out, this unique combination skyrocketed sales of MCUs and the revolution began. Since then and today we’ve added a ton of development boards (product index) and MCU suppliers. Arduino, Raspberry PI, and Beagle Bone, to name a few, have all been very popular with our customers. To make finding boards easier, we created the Development Tools Product Selector guide.
When you think about how technology has evolved from the first fax machine, the internet, microprocessor to microcontroller, cell phones, IoT, 3D printing and artificial intelligence, you must ask: what will be next in the evolution of these exciting times…a Star Trek like transporter or revealing an alien contact?
