iosdefault - all manipulators to default settings.

nostrspace (default) - spaces terminate string entry.

strspace - allow spaces to be input into strings.

Identifier can be a variable that is integer, char, char array, float or fixed point integer type. This function is called for each character, until a r is received. For example usb_cdc_getc() in CCS's usb_cdc.h driver.

function - A function that returns a char.

This provides compatibility for using existing C++ code that explicitly uses the cout stream class.

cin - maps to the default #use rs232() stream.

Result_string << 'Price is $' << setw(4) << setprecision(2) << cost*num << endl Here is a change to the above example to save the formatting to a string variable called result_string: Lcd_putc << 'Price is $' << setw(4) << setprecision(2) << cost*num << endl Here is a change to the above example to display on the LCD using the lcd_putc() function provided in CCS's lcd.c driver: This is transmitted using cout, which is the default RS232 stream. This example transmits 'Price is $' followed by the result of cost*num with two decimal places follwed by the CR/LF. Here is an example usage of this operator:Ĭout << 'Price is $' << setw(4) << setprecision(2) << cost*num << endl

iosdefault - all modifiers back to default settings.

scientific - floating point numbers displayed in E notation (similar to %e in printf()).

fixed (default) - floating point numbers displayed in decimal format (similar to %f in printf()).

noboolalpha (default) - output int1 as '1' or '0'.

boolalpha - output int1 as 'true' or 'false'.

setw(x) - set number of characters output for numbers.

setprecision(x) - set number of places after the decimal point.

dec (default) - When converting variable to string, convert it to decimal format characters (similar to %d in printf()).

hex - When converting variable to string, convert it to hex format characters (similar to %x in printf()).

Identifier can be any of the following manipulators: Identifier can be can be an int, float, fixed point decimal, int1 (boolean) or char array.

For example, lcd_putc() in CCS's lcd.c driver or usb_cdc_putc() in CCS's usb_cdc.h driver. function - A function that takes a char for it's input variable.char array (string) - Data is parsed from identifier and saved to the char array with a null terminator.RS232 stream name - A stream identified with the stream=x option of #use rs232().cout - maps to the default #use rs232() stream.Stream in the above example can be one of the following: For example, if a variable is of float type the compiler will properly convert it from string to float on an input or convert float to string on an output. These conversions are done automatically, no other helper functions like atof() need to be called. One of the key features of this new feature in the CCS C Compiler is the way it automatically handles the conversion based upon the data types of the variables passed.

The beauty of these operators is that the x and y in the above examples can be any combination of function, RS232 serial stream, variable, string and more. When used, these operators show the direction of data. The two new operators added are the extraction operator and the insertion operator: Operator Symbol C++ streams provided a unified interface for I/O and data formatting. Starting with V5 of the CCS C Compiler, CCS has added support for the C++ stream operator. While CCS includes an input.c library that accomplishes many of these tasks, the input.c library uses a fixed RS232 stream and does not work with Keypad/LCD or USB without modification. For example, reading a floating point number from the user over RS232 would require a combination of gets() followed by atof(). In standard C, basic I/O are handled by functions like getc(), putc() and printf() and the formatting of data is handled by functions like atoi(), atof(), strotul() and sprintf().
