Reason for development
When debugging single-chip microcomputers (especially debugging control systems), friends may often have the need to draw real-time variables , and now there are software such as J-SCOPE and STM-STUDIO to achieve this function. But one of their disadvantages is that they only support specific types of debuggers or chip types, but for many debuggers (such as CMSIS-DAP, etc.), they have not found software that can support them.
However, as we all know, OpenOCD is a powerful open source on-chip debugging program, which can support a large number of debuggers and chip types, and supports GDB connection, so I tried to develop this program based on it, and realized such a relatively general debugging assistant LinkScope . Share this with everyone.
Software introduction
software interface
The main function
- View and modify variable values in real time
- Variable value waveform real-time drawing
- Sample data export to CSV table
- format log output
main features
- Support a variety of debuggers (ST-Link, J-Link, CMSIS-DAP, etc.) and a variety of target chips (such as the full range of STM32)
- The fastest sampling speed is about 100Hz (the number of variables may decrease a little)
- The variable to be viewed can be a C language expression (you can add four operations, address operations, etc. to the variable name)
- When the log function is used, the log is output by the lower computer, and four types of logs can be output : information, debugging, warning, and error . The log does not conflict with other functions, and can be used at the same time (it will reduce some sampling speed), and a small program needs to be transplanted to the lower computer
- Support serial port connection, you can use serial port instead of hardware debugger , all functions are exactly the same, you need to transplant a small program to the lower computer, can support various chips that cannot use debugger (such as Arduino, etc.), and can also use transparent transmission module to realize Wireless connections
