IAR development toolchain updated for IoT applications

Swedish company IAR Systems has updated its Embedded Workbench development toolchain for 8051 by adding support for IoT-targeted microcontrollers as well as parallel build for shorten build times.
The 8051 technology has become popular in low-power, sensor-dense IoT applications. To make full use of these devices, developers need tools that create small and smart code.
Version 9.20 of IAR Embedded Workbench for 8051 adds full support for the EFM8 microcontroller series from Silicon Labs. These energy-efficient MCUs are targeted at IoT systems processing data that comes from port IO or sensor inputs. The full tools support includes device support files, header files and debugging capabilities.
The Segger J-Link Plus debug probe is supported with a C-Spy hardware debugger driver, enabling hardware debugging of the devices in addition to C-Spy simulator debugging.
To speed up build times, parallel build has been introduced. The user can set the compiler to run in several parallel processes and make better use of the available processor cores in the PC. This feature can have a major impact on reducing the build times of the compiler.
Embedded Workbench for 8051 is a complete set of development tools for microcontrollers based on the 8051 core. It incorporates IDE tools, the optimising IAR C/C++ compiler and the C-Spy debugger. For simplified development workflows, the tools have integrations for a range of hardware debug systems and device configuration tools.
