You probably have a semicolon at the end of your define. A. define just does simple text substution if you have a. C code, possibly in a place where a. What do these MPLAB C1. When compiling code that assigns pointers or passes them as. C1. 8 tends to provide spurious warnings. These are the most commonly encountered. C1. 8 pointer warnings. This means that an assignment or passing an argument to a. In C1. 8, the qualifiers are const, volatile, rom, ram, near. The most common source of this warning is mismatching a near. C library function. For. example, a call to printf will usually elicit this. If you are compiling with the default small. In this particular case, the warning is. The warning can be suppressed by. C library with the small memory model. In other cases, this warning probably indicates an. This is generally caused by a sign mismatch in a pointer. A common cause is using. For example. void funcchar tring. Another common cause is passing a pointer to an incompatible type. This warning can also be elicited by valid code, such as. To work around this bug, simply cast ccp to the type that memcpy. A cleaner, safer solution is to wrap function calls that trigger. Of course these casts, like any casts, can mask errors in your. But C1. 8 gives you the unfortunate choice between casting and. This generally means an error in your code, such as. It can also be elicited by valid code such as. Why am I getting a syntax error on a declaration in this. Because most PIC C compilers support the C9. This feature was added to. C9. 9 standard. C9. How can I save a float, int, double, long, array, or structure to. Note that this code takes advantage of Cs void type to eliminate. A similar method is used to read. These routines assume you have a routine that can read and write byte. EEPROM. How can I share a global struct or other type among different C. In globals. h. declare an int. Hello, world. include globals. How can I find whats causing the weird behavior in my. MPLAB C1. 8 programSome common causes of strange behavior. An error in your interrupt declaration. C1. 8s interrupt declaration scheme is extremely error prone. Interrupt declaration errors are one of the most. Erroneous interrupt. Ensure you havent mixed up. If youre using assembly. Spending too much time in the ISR. Dont use delays, write to slow peripherals like LCDs, write to. EEPROM, or perform other time consuming tasks in the ISR. If you have an. interrupt that occurs more quickly than one of these tasks, your. ISR and your main code never runs. Calling functions from the ISR Manipulating GIE andor GIEL in the interrupt handler. These are. enabled and disabled automatically by the PIC enabling them in the. ISR can cause unexpected reentrancy. Software stack overflow Inappropriate modifications to the linker file. If youve modified the linker file to create an object larger than. Writing past the end of an array. Writing through an uninitialized pointer. Not using the c. 01. C zeroing behavior is expected. Not compiling with the large memory model on a 1. K PIC. Using a PIC with the fast interrupt errata. The easiest workaround for this errata is to use the interruptlow. Compiling for extended mode with the PIC configured in standard. How can I debug a software stack overflow in MPLAB. Start by reading about how the software stack is implemented in the. Calling Conventions chapter of the users guide. Generally, PICs with at least 5. RAM have a 2. 56 byte. PICs with less RAM have a 6. Check your PICs generic linker file in binLKR to. Look for large objects that use stack space. Things that are. allocated on the stack include function arguments and local. Identify large structures and arrays and. Some library functions, such as the. If youre still getting a stack overflow, here are some. Set a breakpoint at the. When you hit the. AA. This can be done in MPLAB IDE by opening the. File Registers window, right clicking, and selecting. Fill Registers. Let your program continue running. Stop your program and. File Registers window if. Set a complex breakpoint on the last memory address of. This will cause the debugger to halt at the. To set a complex breakpoint. MPLAB IDE Simulator, select Debugger. Complex. Breakpoints. Add Breakpoint. Data Memory. Enter the. last address of the stack memory for example, if your 2. FF, and ensure the. Write. Other debuggers might. Since FSR1 is the stack pointer, you can inspect it at. What is the best way to declare a C1. This avoids the assembly language springboard function which. This technique can generally only be used when not using interrupt. If you need interrupt priorities, this is how to declare the two. GOTO highisr endasm. GOTO lowisr endasm. Yes, you really need five pragmas and four functions to declare two. ISRs in C1. 8. And because the vectors have to be defined as functions. RETURN instruction in each of them C1. RETURNs out. Should I use interrupt priorities on the PIC1. Probably not. By default IPEN 0, the PIC1. PIC1. 6 compatibility mode. This means there is a single interrupt. Even in compatibility mode, interrupts take advantage of the fast. The. disadvantages to using interrupt priorities are many. More interrupt setup code. More complex ISR declaration. Higher latency for high priority interrupts due to the.
