SX C COMPILER

SX C COMPILER from CCS, USA offers a C compiler for the Scenix SX processors. This C compiler is based on original K&R is fully optimized for use on these unique parts. Built-in functions make coding the software very easy. The integrated C development environment provides developers a fast method to produce efficient code from an easily maintainable high level language.

Note: The compiler although based on a 6 year old product is presently in a Beta test state. Purchases made during this period will include one year of updates and a updated manual when the product completes testing.

This integrated C development environment gives developers the capability to quickly produce very efficient code from an easily maintainable high level language. The compiler includes built in functions to access the SX hardware such as SET_TIMER1 to write a value to timer 1. Discrete I/O is handled by describing the port characteristics in a PRAGMA. Functions such as INPUT and OUTPUT_HIGH will properly maintain the tri-state registers. Variables including structures may be directly mapped to memory such as I/O ports to best represent the hardware structure in C. The microcontroller clock speed may be specified in a PRAGMA to permit built in functions to delay for a given number of microseconds or milliseconds. Serial I/O functions allow standard functions such as GETC and PRINTF to be used for RS-232 like I/O. The standard C operators and the special built in functions are optimized to produce very efficient code for the bit and I/O functions.

Functions may be implemented inline or separate. Function parameters are passed in reusable registers. Inline functions with reference parameters are implemented efficiently with no memory overhead.

During the linking process the program structure including the call tree is analyzed. Functions that call one another frequently are grouped together in the same page. Calls across pages are handled automatically by the tool transparent to the user. Functions may be implemented inline or separate. RAM is allocated efficiently by using the call tree to determine how locations can be re-used. Constant strings and tables are saved in the device ROM.

The output hex and debug files are selectable and compatible with popular emulators & programmers for source level debugging.

FEATURES

Built in Libraries that work with all chips for RS232 serial I/O library, I/O, I2C, discrete I/O and precision delays.

Integrates with simulators/emulators for source level debugging. Standard Hex file and debug files ensure compatibility with all programmers.

Formatted Printf allows easy formatting and display in Hex or decimal.

Efficient function implementation allows call trees deeper than the hardware stack.

Source code drivers included for LCD modules, keypads, 24xx &93xx serial E2PROM's, X10, DS1302 & NJU6355 Real Time Clocks, Dallas Touch Memory Devices, DS2223 & PCF8570 Serial SRAM, LTC1298 & PCF8591 A/D converters and more.

Access to hardware features from easy to use C functions.

1,8, and 16 bit types and 32 bit Floating Point.

Assembly code may be inserted anywhere in the source and may reference C variables.

Automatic linking handles multiple code pages.

Inline procedures supported to save stack space; Linker will automatically determine the best architecture or it can be manually specified.

Compiler directives determine if tri-state registers are refreshed on every I/O or if the I/O is as fast as possible.

Constants (including strings and arrays) are saved in program memory.

Standard one bit type (Short Int) permits the compiler to generate very efficient Bit oriented code.

#BIT and #BYTE will allow C variables to be placed at absolute addresses to map register to C variables.

Reference parameters may be used to improve code readability and inline procedure efficiency.

Both an Integrated editor/compiler and a cmd line compiler.

Special windows show the RAM memory map, C/Assembly listing and the calling tree.

Interrupt procedures supported. The compiler generates all startup and clean up code as well as identifying the correct interrupt procedure to be called.

5 or 8 bit pointer support.

Plenty of ready to run example programs are included.

Updates via the web for 30 days included
