What is MISRA C?What is MISRA C?The Motor Industry Software Reliability Association (MISRA) is an organization in the UK that promotes safety in automotive 1998, MISRA published its Guidelines for the Use of the C Language in Vehicle Based Software.

4 The guidelines address the ambiguities of the C languageand establish coding rules for the automotive C includes 127 rules. 93 of these are requiredand the remaining 34 are advisory. All rules apply to the source code and not to the object code generated by the should use MISRA C?Who should use MISRA C?Compliance with the MISRA C guidelines is a require-ment in many automotive companies but could be beneficial in any development guidelines enforce sound coding practices and address the ambiguities of C; they help developers write code in a consistent manner and avoid does it work?How does it work?The IAR MISRA C Checker is completely integrated with the IAR C compiler . From IAR Embedded Workbench, you can control which MISRA C rules are checked; the settings will be used for both the compiler and the linker. Embedded WorkbenchAVR (2_1)5. Project 5.
