RT-Thread RTOS is a real-time operating system for 16-bit to 32-bit microcontrollers, with components which include a hard real-time kernel, a command line shell, a device virtual file system, and a graphic user interface. RT-Thread/GUI is a graphic user interface integrated with RT-Thread. It provides a multi-window, multi-thread graphic user interface. Rich widgets are implemented in RT-Thread/GUI, such as label, button, checkbox, textbox, etc. The typical RAM usage of RT-Thread/GUI is less than 20kB RAM.
Flowgrind is a tool similar to iperf or netperf. It measures throughput and other metrics for TCP and other protocols. It features some unique characteristics: a distributed architecture, sophisticated flow scheduling, Linux kernel TCP statistics, the Anderson-Darling statistical test, rate-limited flows with uniform or Poisson distribution, and separation between control and test traffic.
