AI-generated Summary:
Azure RTOS sample projects demonstrate how to develop applications using ThreadX, FileX, GUIX, NetX Duo, and USBX on Renesas RX family microcontrollers with e2 studio or IAR Embedded Workbench. The projects support various RX devices and include examples for IoT connectivity, low power operation, and secure bootloader integration. Microsoft has contributed Azure RTOS to open source under Eclipse ThreadX, discontinuing official updates. Renesas discontinues the RYZ014A LTE module, recommending Sequans GM01Q as a compatible replacement. Development tools and supported sample projects vary by device, with detailed setup instructions and sample descriptions provided.
