AVR Basic Compiler Library Support


The library support is a new way for the basic statements implementation.
This is indeed an advanced feature, however that is a way that can be used by both the author and the users to extend the compiler language from the external library files.
The information is loaded by the compiler from the external textual .lib files stored in the OshonSoft application data folder.
OshonSoft .lib files are well documented with comments covering all the currently available features of the library support compiler engine.
Library files can be edited by Notepad, or any other plain text editor.

oshonsoftavr.lib file:
 
//the concept is that one library group contains the implementation of one new language functionality - one or more related statements or functions
//library items contain different implementations of the same functionality for different groups of microcontrollers
//#lib_item_begin must be followed by #processor
//#statement_begin, #statement_type, #argument sequence must be fulfilled for proper library load
 
//#processor comma-separated list of processors, x can be used as a wild card character
//#processor can be used in multiple lines to quote all devices if needed
//#parameter is used to implement #define parameters needed for the statement implementation
//#parameter const, parameter_name, allowed_range, default_value
//#parameter symbol, parameter_name, type (pin, bit, byte, address of), system_bit or system_register
//'pin' type is used for the bits in the PORT registers
//'address of' type will implement a constant parameter
//#variable is used to declare global system variables
//#variable variable_name, type (byte, word, long, single, string)
//#statement_begin statement_name [argument1_name[, argument2_name[, ...]]]
//#statement_type type (procedure; inline; function, f_type (byte, word, long, single, string))
//#argument argument_name, type (const xx, byte, byte system xx, word, word system xx, long, long system xx, single, string), passing_type
//the default type of the system variables can not be changed with #argument
//passing_type (byval, byval allowed_constant_range, byref, byrefout) for statement_type procedure and inline
//passing_type (byval, byval allowed_constant_range) for statement_type function
//allowed_constant_range can contain arithmetic expressions in brackets, like 0-[EEPROM_Num-1]
 
//used to define parameters and statements that are not available or not applicable for the current item devices
//#parameter n/a, parameter_name
//#statement n/a, statement_name
 
//used to define alternative names for the parameter and statement names defined in the library group
//#alias_for <library_defined_element_name>, <new_alternative_name>
//used to define code variations among processors when only one or more register names in the code should be replaced with their alternatives
//#alternate_reg_name <register_name_used_in_code>, <alternate_register_name>
 
//code section can contain both inline assembler and basic language lines of code
//symbol and const parameters can be used directly in the assembler lines of code
//calculate[] or calc[] macro is available for double precision calculations
//calculate[] must be used to enter the parameter value in the basic code, will be replaced with the value of the parameter
//calculate[] can be used to perform one arithmetic operation, will be replaced with the value of the result
//calc[] arithmetic operators: +, -, *, /, % (modulus or remainder operator), \ (division returning integer result)
//calc[] macros can be nested
//reg_addr[] macro will be replaced with the register address; if not found, -1 is returned
//Clock_Freq in MHz is available as an argument
//Flash_Num and EEPROM_Num (total number of memory locations) are available as arguments
//int_val() and abs_val() functions are available for getting integer or absolute values of the argument
//int_val() and abs_val() can be used on one or both arguments in calc[] expression, and/or on the whole expression
 
//#if [], #endif macro is available
//#if comparison operators: ==,<>,<,>,<=,>=
//#if [] macro can be used without #endif when followed by one operation in the same line
//for example: #if [libtemp3 > 0.5] #math libtemp2 = calc[libtemp2 + 1]
//for example: #if [ADC_Ref > 3] sbr R30,0x10
 
//'const' statement argument type can be used to load the numeric value into one of the library engine temp variables libtemp0-libtemp99
//for const arguments only 'byval' and 'byval allowed_constant_range' passing types are allowed
//#math directive is used to assign numeric value or the result of calc[] expression to one libtempxx variable
//for example: #math libtemp8 = calc[calc[Clock_Freq * 1000000] / calc[calc[libtemp2 + 1] * 4]] //exact baud rate achieved
//#if macro also works with libtemp0-libtemp99 variables
//desired info can be inserted as a comment in the generated assembler source with the #echo directive
//#echo is followed by a string that can contain temp variable names to be replaced with their numeric values
//for example: #echo "exact baud rate achieved = libtemp8; bit period = libtemp7s; baud rate error = libtemp6%"
 
//when calling 'procedure' type statements with one 'byval' byte argument declared, library engine will accept multiple comma-separated arguments
//for that purpose #statement_accept_multiple_arguments directive should be placed after #statement_type
//variables are passed byte by byte staring from the lowest byte; string constants can be used, along with symbolic constants Qt, CrLf, Cr, Lf
//decimal representation of a variable can be passed to the procedure by using the # prefix before the variable name
//#break_for_string_argument directive
//for string variables and decimal representations (argument in the form #variable_name)
//library engine will load XHL register (X-register) with address of zero-terminated string prepared in memory
//and call the procedure at position of the #break_for_string_argument directive in the procedure code
//when calling 'procedure' type statements with one 'byrefout' byte argument declared, library engine will also accept multiple comma-separated arguments
//variables are filled in byte by byte staring from the lowest byte
 
//be careful that basic statements like WaitUs also make use of the system registers and can alter those values
 
//special function registers are declared in basic code as byte variables; if needed, this byte variable type can be changed with #redim directive
//#redim register_name new_type (byte, word, long, single)
 
//list of available compiler system byte registers: R16, R17, R18, R19, R20, R21, R22, R23, R24, R25
//list of available compiler system byte registers: R26 (XL), R27 (XH), R28 (YL), R29 (YH), R30 (ZL), R31 (ZH)
//list of available compiler system byte registers: R0, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15
//list of available compiler system word registers: R1716, R1918, R2120, R2322, R2524
//list of available compiler system word registers: R2726 (XHL), R2928 (YHL), R3130 (ZHL)
//list of available compiler system word registers: R1R0, R3R2, R5R4, R7R6, R9R8, R1110, R1312, R1514
//list of available compiler system long registers: R19181716, R23222120, R27262524, R31302928
//the compiler holds zero value in R15 system register
//the compiler uses R16 system register as working register
//registers R16-R31 are much better covered by AVR instruction set
