GST# R131905739 ** Common Questions and Answers ** Q: Is MICRO-C a full ANSI compiler? No, MICRO-C is a "subset" compiler. It does however, support much more of the 'C' language than most other subset compilers, including: - All 'C' statements: if/else while do/while for break continue return goto switch/case/default {} ; asm - All 'C' operators: + - * / % & | ^ << >> > < == ~ ++ -- ?: , . -> += -= *= /= %= &= |= ^= <<= >>= >= <= != ! () [] sizeof - The following data types: int char unsigned (including: unsigned char) struct union extern static register *(pointer to any type, incl. pointers and structs) - Arrays of any type (incl. multi-dimension, pointers & structs) - Function can return any type - Typecast of values to other types - Decimal, Octal and Hex constants. eg: 127, 0177, 0x7f - Full support for strings and character constants: ('' "") Including: \n \r \t \b \f \177(Octal) \x7F(Hex) (16 bit character constants are supported. eg: 'ab') - Inline assembly code (single or multi statement). - Preprocessor commands: #define (fully parameterized & multi-line) #undef #forget (multi undef -similar to FORTH forget) #include #ifdef/#ifndef/#else/#endif (fully nested) #file (sets filename displayed in error messages) - It DOES NOT support: Typedef, Long* / Double / Float / Enumerated data types, Bit fields. * 32 bit "long" number math functions are provided in the library. These may be easily adjusted to manipulate numbers up to 256 bits. Q: Is MICRO-C just another version of SMALL-C? No, MICRO-C is a completely new design, with several advantages: - Supports more of the 'C' language: structs & unions, unsigned int & char, pointers to pointers, arrays of pointers, multi-dim arrays, typecasting, sizeof, parameterized and multi-line defines ... - Much more efficent code generated, much faster compilation. - More portable: MICRO-C was designed to support many CPU architectures. Q: Does MICRO-C run on a (Macintosh, UNIX box, etc...)? Although MICRO-C is distributed mainly for the IBM PC, the compiler can be re-compiled to run in virtually any environment. The sources to the compiler are in 'C', and were written to be very portable. NOTE: If you are really ambitious (or desparate!), you can port MICRO-C to a system without a 'C' compiler, by first porting MICRO-C into a cross compiler for the target system, and using it to re-compile itself! Q: Does MICRO-C output assembly code? Do I need an assembler? MICRO-C generates assembly code. All developers kits and porting packages include our XASM cross assembler, which our CC commands automatically run for you, giving you a "one step" compile. A command option allows you to include the 'C' source code as comments in the ASM listing. Q: Does MICRO-C support the (insert favorite processor)? See the CATALOG for a list of processors which we directly support. We have application notes on adapting the compiler to use with CPU variants (such as extra registers/ports or differing memory maps). It is also possible to "port" the compiler to a CPU for which we have not provided support. You would need the "MICRO-C Source Package", which contains detailed documentation on porting to a new CPU, however this is not a task for the novice programmer. Before attempting this, please check with us. We may be planning a release for the processor you want (or perhaps you can "convince" us that is would be a good idea). Q: How much code can I fit in (nK) of memory? That depends on so many factors that its impossible to give you a general answer. It is usually more that you would think, because MICRO-C produces fairly compact code. This is especially true with our "Developers Kits", because their libraries are hand-coded in assembly language, using very tight code. Here are some examples of appications: MICRO-C Compiler (compiled itself!) 23K ANSI terminal with built in XMODEM file transfer 10K Combination lock (rotary encoder, led indicator) 2K Telephone "distinctive ring" switcher (1 - 3 lines) 1.5K Q: Is your EMILY52 simulator really that fast? EMILY's speed is dependant on your PC (>150,000 inst/sec on 386/25, >500,000 inst/sec on 486/33). My tests have shown EMILY on the 386/25 to be roughly equivalent to a 4Mhz 8052. For example, a customer reported that an algorithm he had calculated would take about 1 second on a 12Mhz 8052 took 3 seconds under EMILY. In contrast, the same program took over 20 MINITES when run with another popular simulator. Q: Is MICRO-C really as good as you say it is? Sturgeons Rule has it that 90% of science fiction is junk. A similar rule applies to PC software, but I'd say that 90% is a lower bound. Once in a while, though, you find a product that makes up for the rest.. If price has kept you out of the microcontroller C market, you have no further excuses. Micro-C is as good as it gets! - Circuit Celler INK Dec91/Jan92 I just obtained Micro C, and I'm very impressed!... The portability of Micro C is second-to-none, as is it's professionally written code and overall usability... I need to emphasize here that Micro C is by far the best coded compiler I've ever seen. This excellent code quality extends throughout all associated modules. - FIDOnet 'C' programmers echo Dave, Thanks for responding to the minor problem I had with your wonderful little compiler. - A satisifed customer
