IAR Embedded Workbench for 8051 includes the following new and enhanced functionalities:
Highlights in version 9.20
- Support for Silicon Labs EFM8 devices
The new 8051-based microcontroller series from Silicon Labs - EFM8 - is now fully supported by IAR Embedded Workbench for 8051. This includes device support files, header files and debugging capabilities within both the C-SPY Simulator and C-SPY J-Link driver. The new supported devices are: EFM8BB10F2G, EFM8BB10F4G, EFM8BB10F8G, EFM8BB21F16G, EFM8BB22F16G, EFM8SB10F2G, EFM8SB10F4G, EFM8SB10F8G, EFM8SB20F16G, EFM8SB20F32G, EFM8SB20F64G, EFM8UB10F8G, EFM8UB10F16G, EFM8UB11F16G, EFM8UB20F32G, EFM8UB20F64G.
- New C-SPY debugger driver with support for EFM8 devices
Debugging Silicon Labs devices with the C2 debug interface has been improved - The SEGGER J-Link Plus Debug Probe is now supported with a new C-SPY hardware debugger driver. This makes it possible to debug the devices from Silicon Labs, both the EFM8 devices and also many of the C8051Fxxx devices.
- Parallel build
The compiler can now run in several parallel processes to better use the available processor cores of your PC. To control parallel build, select Tools>Options>Project>Enable parallel build.
- XLINK logging configurable in the IDE
A new options page to control the log file from the IAR XLINK Linker has been added: Project>Options>Linker>Log. Since version 6 of XLINK there exists a command line option --log, that produces a log listing; this is now configurable from within the IDE.For more information about what the linker can log, and how the log file should be interpreted, see the IAR Linker and Library Tools Reference Guide.
- Updated user documentation
The IDE Project Management and Building Guide, and the C-SPY Debugging Guide have been updated.
Highlights in version 9.10
- Full tool support for 8051 IP cores by CAST
Together with IAR Systems, CAST has developed a C-SPY Debugger driver plugin with support for their native on-chip debug package with an external adapter (pod). It is available for JTAG or single-wire SWAT debugging. For ordering information, contact CAST.
- Full device support has been added to the IAR Embedded Workbench for 8051 for all available CAST device core families: S8051XC3, R8051XC2, L8051XC1
- Support for devices with a Multiplication-Division Unit (MDU) has been added. This makes it possible to from within your code use hardware accelerator options for multiplication and division, which inherently is expensive in an 8-bit microcontroller.
- Improved compiler optimizations
The compiler generally generates less code for your application. Especially if you use the Large or Far data model, the code to access xdata memory should become smaller.
- New windows for C-SPY macros
Two new C-SPY windows have been added to easier manage C-SPY macros. The Macro Registration window controls which macro files are loaded and the Debugger Macros window shows a list of all macros available in the debugger.
- Saving C-SPY Watch window content
In the C-SPY Watch window family, you can now choose Save All to File from the context menu to save the contents of the current window to a text file.
- Simplified device selection
Selecting a device in the Project Options dialog has been improved and simplified. Now you choose your device from a static menu, instead of having to explore the file system of your Embedded Workbench installation.
- Debugger Reset with or without Run to 'main'
The C-SPY Debugger Reset button has been improved to let you select whether to run to main or not without leaving the debug session. The debugger will override the project settings and insert or remove this breakpoint for you. Note that this might consume a hardware breakpoint if you debug on hardware.
- Device Support
This includes support for new devices:
CAST - see above
Silicon Laboratories - C8051F336-9
Highlights in version 8.30
- Generalized Extended Stack Support
It is now possible to use any 9- to 16-bit extension of the stack pointer by having a bit mask that is applied to the SFR that handles the extra bits in the combined extended SP. A limitation that assumed a 10-bit extended SP (such as for DS80C390 devices and similar) is removed.
- Library Build Factory Template Projects
Template projects to reproduce the runtime libraries are now available from the Create New Project menu option.
- Simplified Option Handling
The design of the General Options pages is improved. The often used Stack/Heap page has been moved to be more easy to access, now found as second tab in line.
- Project Connection
Files or file packages generated by external code generation tools can be imported and the IAR Embedded Workbench IDE will automatically detect changes in the generated file set. This enables automated integration with a number of device configuration tools, including Infineon's tool DAVE.
- New and Updated Device Support
This includes support for new devices:
- Silicon Labs - C8051F85x/86x
- AXSEM - AX8052F100/131/143/151
