With comprehensive support for modern C/C++ language standards, the toolchain generates highly efficient code for microcontrollers The Arm Compiler and C/C++ libraries have been tuned for real-world embedded applications. In addition to bringing together essential development tools and system views, it features the Pack Installer, an intelligent component manager that takes care of downloading, installing, and keeping track of inter-dependencies for each pack component used in the code. Occupy a continuous range of numbers starting from 8.MDK's intuitive IDE has been specifically optimized for embedded developers over many years. SWI functions 0.7 are reserved for the RTXĭo not leave gaps when numbering SWI functions. Your SWI function should now look like this: Then add a reference to it into the table: */Īdd the function _SWI_ x to the SWI function * A protected function to increment a 5-bit counter. Later by the linker from SWI_Table.s module. Write a function implementation and convert the function name The first SWI number, starting from 8, that is free. This file is located in the \Keil\ARM\RL\RTX\SRC\ARMĭeclare a function with a _swi( x) attribute. If you want to use SWI functions in your RTX kernel project, youĬopy the SWI_Table.s file to your project folder and When the ARM controller leaves this mode, interrupts are Note that the FIQ interrupts are not disabled in Running mode to a Supervisor Mode and blocks any further IRQ When executing the SWI instruction, the controller changes the SWI functions are called by executing the SWI instruction. It generates different code instructions to call SWIįunctions. The difference is hidden to the user and is handled by theĬ-compiler. SWI functions can accept arguments andĬan return values. Supervisor Mode of ARM7™ and ARM9™ core and are Software Interrupt (SWI) functions are functions that run in RL-ARM User's Guide (MDK v4) RL-RTX Overview Product Description Product Specification Technical Data Timing Specifications Advantages Your First RTX Application Theory of Operation Timer Tick Interrupt System Task Manager Task Management Idle Task System Resources Scheduling Options Pre-emptive Scheduling Round-Robin Scheduling Cooperative Multitasking Priority Inversion Stack Management User Timers Interrupt Functions Configuring RL-RTX Configuration Options Tasks Stack Size Stack Checking Run in Privileged Mode Hardware Timer Round-Robin Multitasking User Timers FIFO Queue Buffer Idle Task Error Function Create New RTX_Config.c Configuration Macros Alternate Tick Timer Low Power RTX Library Files Using RL-RTX Writing Programs Include Files Defining Tasks Multiple Instances External References Using a Mailbox SWI Functions SVC Functions Debugging System Info Task Info Event Viewer Usage Hints ARM7/ARM9 Version Cortex-M Version Create New RTX Application Function Reference Event Flag Management Routines Mailbox Management Routines Memory Allocation Routines Mutex Management Routines Semaphore Management Routines System Functions Task Management Routines Time Management Routines User Timer Management Routines RL-FlashFS RL-TCPnet RL-CAN RL-USB Example Programs Library Reference Appendix
