![]() ![]() It's USB based and uses a high-speed MCU internally, not an FTDI convertor like most low cost debugger.Of the dozens (and dozens!) of debuggers out there (we have literally drawers full of them!), we chose the J-Link for a number of reasons: Essentially, it's a direct window into what's going on inside your MCU at any given moment, giving you a level of access and control that's not easy to replicate with other debugging methods. It allows you to program your devices at the click of a button, read or write memory addresses or registers on a live system, temporarily halt program execution at a given location or condition, and much more. This is the best JTAG/SWD programmer/debugger, you will thank yourself for investing in this industry-standard tool!ĭoing some serious development on any ARM-based platform, and tired of 'printf' plus an LED to debug?Ī proper JTAG/SWD HW debugger can make debugging more of a pleasure and less of a pain. ![]() ![]() On the other hand if you're making money, or plan to make money off your project, then you're in the right place with the SEGGER J-Link BASE - JTAG/SWD Debugger. If you're going to use your debugger strictly for personal, non-commercial projects, such as publishing open source designs that you're not selling, then you should get the EDU version! It's the same but significantly cheaper. The SEGGER J-Link BASE is identical to the cheaper J-Link EDU model except for the terms of use. ![]()
