MISRA is going to look at doing a MISRA C++ Is anyone interested in being on the panel? They are looking for experienced industrial embedded C++ people rather than standards lawyers. If anyone is interested let me know and I will pass your details on to the panel chairman. He was not silly enough to put his own e-mail address up on this request :-) The main team will be fairly smal...

Hi! I would like to define a pointer to a hardware register. I have done as follows: typedef unsigned int Hw_Register; volatile Hw_Register* const gp_dor_address = (Hw_Register* const)0x84501500; When checking against MISRA I get the following error: line 74: error #1703-D: MISRA Rule 45: cast from type "unsigned int" to type "Hw_Register *" not allowed volatile H...

Hi, I have been talking to all the embedded compiler companies about the next version of MISRA-C ie MISRA-C:2010 and their views on changing the reference from C95 to C99 as a basis. So far I have not managed to get any response from Imagecraft or CCS If any one has a good contact for them (is does work for them) please let me know If anyone works for an embedded compiler co...

I'm currently rewriting some numerical code for MISRA compliance. Signed shifts are not defined by the C-standard, and the code-checker complaints. Well - no big surprise here. I knew that and did it nevertheless. Now I have to rewrite. But do you do if you need them anyway? I need *lots* of them, so in despair I've just created this monster of unreadable code: int ArithmeticShi...

Hi, I need a tool to check C code MISRA-C 2004 compliance: as I need it for various embedded compiler (GNU-ARM, Freescale CodeWarrior and AVRStudio), I thought about an external code checker (like PC-Lint for example). What can I use? Thank you

Hi, I am just curious to know what the reason behind MISRA rule 111. The rule says - Bit fields shall only be defined to be one of type unsigned int or signed int I have used UINT32 instead of unsigned int in my code but compiler has thrown a warning says - "field type should be int" Could somebody please put light on this. Thanks Vikas -----------------------------...

Hi, In MISRA-C 2004: Rule 10.4: The value of a complex expression of integer type may only be cast to a type that is narrower and of the same signedness as the underlying type of the expression. Rule 10.3: The value of a complex expression of floating type may only be cast to a type that is narrower floating type. So why should the cast be more narrow? The Guidelines giv

Ok, I admit this is just a personal preference of mine but I just wondered if anyone else felt the same way. So here comes the suggested rule "Never use characters that cannot be pronounced" Here are some highly contrived examples: (1) __loop. Well, how are you supposed to drop that into polite conversation? What if you have another variable called loop. How do you verbally differenti...

In reply to my previous post, Paul Rubin says: "I think MISRA C disallows function pointers, partly for this reason." Are function pointers really bad things? Sincerely I found them useful and lastly I was using them more and more. Am I wrong? Function pointers help me in at least three situation. With function pointer I can isolate C modules from the rest of the project, so ...
