• Can the compiler automatically remove unused functions from my application?
• How do I access global variables declared in C from an Assembly module?
• Why do I receive the linker error "function not defined" when the function is defined in an assembly source file?
• Why does my non-zero initialized global data appear as all zeros when I view memory in my debugger?
• Why does the compiler optimize (remove) code necessary to access some of my data objects?
• Do I have access to library functions used by Cosmic to change its default behavior?
• When I use printf() and sprintf() with float arguments and include the floating point library (libf) in my link command file, why do I get the unexpected results?
• What order should I link the Cosmic libraries?
• How do I use the Compilers on-chip EEPROM data erase and write features?
• How can I copy a block of data to the on-chip EEPROM?
• What is the zero page and what is it used for?
• How do I locate data objects explicitly in the zero page or external memory?
• What is the difference between the Data and BSS sections?
• Can I create my own segment names other than the reserved segment names used by the linker?
• How do I set a data object or function to a predefined address?
• What is the VOLATILE qualifier?
• Will the compiler work with my specific processor?
• What does the acronym BSS represent?
• I would like to use printf or sprintf, but the code is too large for my available space. Are there smaller versions for simple applications?
• When I declare a global zero page, eeprom or const pointer it does not seem to be allocated in the correct memory section?
• The results of an expression evaluation seem to be truncated or incorrect. When do I need to add a cast to a C expression?
• How do I force the compiler to check for ANSI C prototypes?
• Are there any options to force the compiler to perform stricter type checking then ANSI C requires?
• How do I locate a piece of code in ROM and copy it into RAM for execution such as with a boot loader?
• How do I write my own ISRs (Interrupt Service Routines) and can I call an interrupt function from another function?
• Do I have to change the vector table when writing an ISR?
• I have an application that requires the Cosmic libraries to be linked in two locations. How do I link more than one copy of the same library without name conflicts?
• How do I extract S-Records for just a segment of code or data?
• How do I store a specific value at a specific memory location in ROM/Flash? Why Can't I use the absolute addressing feature?
• How do I force the compiler to allocate data objects in the order I declare them. It seems some are allocated in the reverse order and some are allocated in the order declared.
• The end record (S7, S8 or S9) in my application's S-record is not compatible with my ROM burning program and/or the verification utility. Can I change this?
• How are bitfields allocated?
