Inline code for functions? Adding parenthesis just isolate the multiplication and the multiplication result is still 8 bit unsigned. Storing packed strings and other data in flash devices 16F87X The cdata definitions should be put in a separate file and included in the beginning of the program. Switching between bank 0 and 3, or bank 1 and 2 require more instructions than the other combinations. PicBasic v2. An easier approach is to align the LSB to a certain value as long as program size is not critical. If the compiler generates application code bugs, it is almost always possible to rewrite the program slightly in order to avoid the bug.

The reason for the error is that local variables are allocated statically and may be overwritten if the routine is interrupted and then called during interrupt processing. The error message can be changed to a warning by the following pragma statement.

Note that this means that local variable and parameter overwriting must be avoided by careful code writing. The compiler will write the output from the preprocessor to a file. CPR when using the -B command line option. Preprocessor directives are either removed or simplified. Macro identifiers are replaced by the macro contents.

When using the alternative preprocessing formats -Bpims , compilation will stop after preprocessing. Note that direct coded instructions are different from inline assembly seen from the compiler. The compiler will view the instruction codes as values only and not as instructions.

All high level properties are lost. The compiler will reset optimization, bank updating, etc. These statements can only be used inside the functions:. It is possible to use pragma origin to ensure that a computed goto inside a function does not cross a word address boundary.

However, this may require many changes during program development. An alternative is to use pragma alignLsbOrigin to automatically align the least significant byte of the origin address.

Note that this alignment is not possible when using relocatable assembly, and also that it does not apply to the 12 bit core. A function contain a computed goto. After inspecting the generated list file, there are 16 instructions between the function start and the first destination address offset 0 right after the ADDWF PCL,0 instruction that perform the computed goto.

The last destination address offset 10 resides 10 instructions after the first destination. A fast a compact computed goto requires that the first and last destination resides on the same "byte page" i. This is achieved with the statement:. The alignment pragma statement is not critical. The compiler will generate an error option -GS or a warning -GW if the computed goto cross a boundary because of a wrong alignment. An easier approach is to align the LSB to a certain value as long as program size is not critical.

This is now selectable.

The switch statement now supports variables up to 32 bit. The generated code is more compact and executes faster than the equivalent 'if - else if' chain.

The concatenation operator allows tokens to be merged while expanding macros. The stringification operator allows a macro argument to be converted into a string constant. The interrupt routine normally have to reside on address 4. The following pragma statement will allow the interrupt routine to be placed anywhere.


Note that the compiler will NOT generate the link from address 4 to the interrupt routine automatically. The compiler will print info at the end of the assembly file. Total code size, code size on each code page, maximum call level, RAM usage. In addition, the size of each function is printed. Command line option -Au removes this information.

Single lines from multiline macros are printed in the generated assembly file when using command line option -AR. This is sometimes useful to improve readability when expanding very long macros.

If there is a syntax error in a defined macro, then it may be difficult to decide what the problem actually is.

This is improved by printing extra error messages which points to the macro definition, and doing this recursively when expanding nested macros. CC5X is able to automatically increment one or more version numbers for each compilation.

Syntax supported:. Note that the command line option is required to make this increment happen. It is the decimal number found at end of the included file that is incremented. The updated file is written back before the file is compiled. No special syntax is assumed in the version file.

If the decimal number is 99, then the new number will be and the file length increase by 1. If the number is , then the file length remains the same. A version file should not be too large up to 20k , otherwise an error is printed.

Formats 2 and 3 above allows more than one version file. It is recommended to use conditional compilation to manage several editions of the same program. Variables can overlap parts of another variable, table or structure. Multiple levels of overlapping is allowed.

An expression can now define the address of a variable. This makes it easier to move a collection of variables.


This warning is changed to an error when using relocatable assembly option -r. It is possible to force the compiler to generate inline integer math code after a math library is included. This may be useful when speed is critical or in the interrupt service routine. Functions with parameters or local variables are not reentrant because local variables are mapped to global addresses, and therefore the compiler will not allow calls from both main and the interrupt service routine to the same function.

It is possible to combine inline integer math and math library functions without making a special purpose math library. It is optimal to use inline code when there is only one operation of a certain type.

The math prototypes are found in the beginning of the standard math libraries. Just remember to remove the operator name before adding the inline type modifier. A warning is printed when there is ONE call to a unsigned integer math library function. The warning can be disabled by the -wm command line option. The compiler will print a warning when detecting more than one inline math integer operation of the same type.

Including a math library will save code, but execute slightly slower. The FAQ at http: Select the correct. You must get the crystal speed correct. Options are 3. For example, a 16F, 16Mhz, downloading at baud would be " - bootldr-vFMhzbps. Recompile your code so it doesnt overwrite the bootloader.


This will not normally be necessary, unless your program occupies a lot of memory. The bootloader uses instructions at the top of flash. This section only applies to bootloader v and below. If the bootloader doesnt work, check this out. The first 4 bytes in the. It is known that the CC5X compiler, a Pascal compiler and various assembly language programs do not have this long jump.

If the. The first 4 bytes should have instructions similar to the instructions below: Program the target pic micro with this. Third party programmers are discussed at http: Choose bps, write eeprom, and the. To test that the bootloader is working, use the supplied test files.

All they do is write serial characters out of the serial port. Click "Write" within the windows application software. It should display the message "Searching for bootloader Reset PIC micro now, and the writing will begin. The test program simply prints out a single text message baud on powerup.


Run 'com1. In future, after powerup, bootloader times out in ms and then runs the target program normally.


Compatibility list Note: Your email may save lots of users a lot of time, as it allows me to fix the bootloader. I am currently working on a version of the bootloader which works with the CC5X compiler - email me if you want a quick fix. This version of the compiler is known to have issues with the CC5X compiler, and Pascal compiler. These both work if a long jump is inserted into the first 4 bytes see troubleshooting.

Troubleshooting step-by-step. Nothing works - where do I start? You need a chip programmer to get the bootloader. It is only after the bootloader has been programmed into the PIC micro that new programs can be loaded into the micro using only the RS serial port on a PC. The top 4 programmers available are: Next, check that your circuit is correct. Program your PIC with the. It should repeatedly output a string: However, first you must re-assemble the included.

Normally, the bootloader uses the top instructions in memory. In the supplied. Check crystal speed, and re-assemble. This reserves the top instructions, and some ram 0x70 and more for the ICD. Now, remember to have enable debug mode set to 'off', see the screenshot here. Program the bootloader.

Troubleshooter is Finished. Are you waiting for coming features? The 1 year update agreement ensures that you get the new features introduced within 12 months after purchase. Multitasking support using state machines is available. Many highly reliable and complex systems are built using state machines, for instance in telecommunications. A normal RTOS can impose unpredictable response delays. State machines are predictable, fast and allows the maximum delay to be calculated. So, try state machines and discover how you can use PICmicros for complex real time control jobs.

The compiler has been and is still leading in generating compact code.
