Debugger toolchain supports IoT-targeted MCUs

The 8051 technology has become very popular in low-power, sensor-dense IoT applications. To make full use of these devices, developers need powerful, easy-to-use tools that create small and smart code. Version 9.20 of IAR Embedded Workbench for 8051 adds full support for the EFM8 MCUs series from Silicon Labs.

The energy-efficient EFM8 MCUs are targeted for IoT systems processing data that comes from port I/O 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 new C-SPY hardware debugger driver, enabling hardware debugging of the new devices in addition to C-SPY Simulator debugging.

In order to speed up build times, parallel build is introduced. The user can easily 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.

IAR Embedded Workbench for 8051 is a complete set of development tools for MCUs based on the 8051 core. It incorporates IDE tools, the highly optimising IAR C/C++ Compiler and the comprehensive C-SPY Debugger. For simplified development workflows, the tools feature integrations for a range of hardware debug systems and device configuration tools.
