Development reasons

Debugging MCU （ Especially debugging the control system ） When , Small partners may often have to test variables Real time drawing The needs of , Now there are also things like J-SCOPE and STM-STUDIO Such software realizes this function . But their big disadvantage is that they only support the specified type of debugger or chip type , And for many debuggers （ Such as CMSIS-DAP etc. ） But I haven't found any software that can support .

But as we all know OpenOCD Is a powerful open source on-chip debugging program , It can support a large number of debuggers and chip types , Support GDB Connect , So I try to develop this program based on it , It realizes such a general debugging assistant LinkScope, Let's share with you .

The software is introduced

software interface

The main function

1. real time see and modify A variable's value
2. A variable's value Real time waveform rendering
3. sampling Export data To CSV form
4. format Log output

The main features

1. Support Multiple debuggers （ST-Link、J-Link、CMSIS-DAP etc. ） as well as Multiple target chips （ Such as STM32 A full range ）
2. The fastest sampling speed is about 100Hz（ The number of variables may decrease a little ）
3. The variables added to view can be C Language expressions （ You can add four operations to the variable name 、 Addressing operation, etc ）
4. When using the log function, the log is output by the lower computer , Can output Information 、 debugging 、 Warning 、 error There are four types of logs . Logging does not conflict with other functions , Can be used at the same time （ It will reduce some sampling speed ）, Need to transplant a small program to the lower computer
5. Support serial port connection , Sure Use serial port instead of hardware debugger , All functions are completely consistent , Need to transplant a small program to the lower computer , It can support various chips that cannot use the debugger （ Such as Arduino etc. ）, It can also use transparent transmission module to realize wireless connection
