'''Segger Microcontroller'''
==History==
Segger Microcontroller was founded in 1992 by Rolf Segger in [[Hilden]], Germany.<ref name="Segger-About-Company">{{cite web |title=About Us - The Company |url=https://www.segger.com/about-us/the-company/ |website=Segger |archive-url=https://web.archive.org/web/20241206190958/https://www.segger.com/about-us/the-company/ |archive-date=December 6, 2024 |url-status=live}}</ref> The first product was the [[real-time operating system]] (RTOS), now named embOS. It was followed by emWin two years later. Initial products focused on RTOS and [[middleware]] products. However, the company later produced ISP-programming tools (Flasher) and debug probes (J-Link). In 2015, Segger introduced Embedded Studio, their [[Cross-platform software|cross-platform]] IDE for [[central processing unit]]s conforming to the [[ARM architecture]], though recent versions are also used by [[RISC-V]]. All products are developed, maintained and updated in Germany except for Embedded Studio, which is primarily developed by a team of developers in the [[United Kingdom]].
