Arduino uploads data to shell Iot platform and interacts with FPGA. arduinofpga This article implements the interaction between Arduino and FPGA. Of course, there is no new protocol, or it is based on serial communication. Now, learning a serial communication can basically drive most modules, moreover, it can seamlessly interact with various single-chip microcomputer da
Data standards are the core of Iot Big integrated applications The essence of Iot is M2M, that is, communication between machines. Here we talk about machine in a broad sense. It can be as small as a "Smart Dust ", for example, an RFID chip or a biosensor embedded in the human body is as big as a high-speed train or a space shuttle, m2M can be a one-to-one or mu
In the book "evolution of the Internet", we propose that "the future functions and structure of the Internet will be highly similar to that of the human brain, and the virtual perception of the Internet, virtual movement, virtual hub, and virtual memory neural system will be available"And draw a structure of the Internet virtual brain. Based on this point of view, we try to analyze the relationships between the four most popular Internet concepts ----------- big
