Technical Blog / Chili Board, Linux IoT platform that can quickly develop networked support for multi-cloud
https://www.nuvoton.com/support/technical-support/technical-articles/TSNuvotonTechBlog-000320/
According to the statistics of research institutes, the number of globally networked devices in 2020 exceeded 20 billion units. More than half of them (10 billion) was IoT (Internet of Things) devices. This number continues to increase; it is estimated that by 2025, globally networked devices will exceed 30 billion units. Among the networked IoT applications, many functions had to be realized through Linux, but product development with traditional Linux is complex. The main reason is that it is difficult to set up Linux development environments and complicated hardware settings, which all cause the development schedule to increase. Nuvoton’s Chili Board is for solving difficulties encountered by users, allowing developers not having to waste time setting up Linux interactive compilation environments and not having to perform complicated network settings; use the VMware virtual machine and Linux BSP provided by Nuvoton to complete the development of Linux networking quickly.
Technical Blog / Multi-protocol converter solution
https://www.nuvoton.com/support/technical-support/technical-articles/TSNuvotonTechBlog-000317/
As IoT cloud technology develops, industrial communication often shares information and exchanges data between multiple devices. Most of the factory automation nowadays uses RS-232, RS-485, CAN, and Ethernet interfaces to interconnect. Still, since the communication protocols of the various interfaces are not compatible with one another, all information must be uploaded to the cloud through the internet to satisfy industrial IoT needs. Therefore, using a specific hardware converter to convert interface data such as serial or RS485 through protocols and then sending them to the internet is one way to go. This particular hardware is the Nuvoton multi-protocol converter chip that we will introduce today, NuMicro® M487 and NUC980. Multi-protocol converters are also called bridges; they allow hosts that use different high-level protocols for network communication to communicate with one another. They support various distributed industrial control applications, and the commonly used
