CCStudio IDE v21.0.1 — What’s New
New Features
| Issue | Summary |
|---|---|
| EXT_EP-12257 | Need ability to specify where to save Target Configuration file (ccxml) |
When creating a target configuration file there should be the ability to browse to where you want to save the file. It only saves to the default location. CCSv12 and earlier could specify the location. |
|
| EXT_EP-12966 | Option to export all messages in the Problems view to a log file |
Open to export all messages in the Problems view to a log file, or at least the ability to "Select All" like what was available in CCS Eclipse. Note that it is possible to multi select lines by selecting a line and then holding down SHIFT button and then selecting another line to select all the lines in between. Then use CTRL+C and CTRL+V to copy and paste. However this doesn't work well with many lines so it is not a viable workaround. |
|
| EXT_EP-13051 | Support expression values when exporting/importing to/from JSON text file |
The Watch view has the option to import/export expression names from/to a JSON text file. This request is to also support expression values. Allow the user the option to include the values on export. Also allow the user to choose if they wish to import the names and also write the associated values stored in the JSON file. If there are no values in the JSON file then only the names will be imported. |
|
| EXT_EP-13259 | Read, reset, configure profile clock Tool API |
Need tool call API to read, reset, enable, disable profile clock. |
