Info

Here is a function that calculates and returns the sum of all variables: int Sum(int count, ...) { //a pointer to the argument list va_list al; int x, sum=0; //start the argument list //count is the first variable before the ellipsis va_start(al, count); while(count--) { //get an int from the list x = var_arg(al, int); sum += x; } //stop using the list va_end(al); return(sum); } Some examples of using this new function: x=Sum(5, 10, 20, 30, 40, 50); y=Sum(3, a, b, c); 40
FUNCTIONAL OVERVIEW I2C I2C is a popular two-wire communication protocol developed by Phillips. Many PIC microcontrollers support hardware-based I2C. <strong>CCS</strong> offers support for the hardware-based I2C and a software-based master I2C device. (For more information on the hardware-based I2C module, please consult the datasheet for you target device; not all PICs support I2C.) Relevant Functions: i2c_start() i2c_write(data) i2c_read() i2c_stop() i2c_poll() Issues a start command when in the I2C master mode. Sends a single byte over the I2C interface. Reads a byte over the I2C interface. Issues a stop command when in the I2C master mode. Returns a TRUE if the hardware has received a byte in the buffer. Relevant Preprocessor: #USE I2C Configures the compiler to support I2C to your specifications. Relevant Interrupts: #INT_SSP I2C or SPI activity #INT_BUSCOL Bus Collision #INT_I2C I2C Interrupt (Only on 14000) #INT_BUSCOL2 Bus Collision (Only supported on some PIC18's) #INT_SSP2 I2C or SPI activity (Only supported on some PIC18's) Relevant Include Files: None, all functions built-in Relevant getenv() Parameters: I2C_SLAVE I2C_MASTER Returns a 1 if the device has I2C slave H/W Returns a 1 if the device has a I2C master H/W Example Code: #define Device_SDA PIN_C3 #define Device_SLC PIN_C4 #use i2c(master, sda=Device_SDA, scl=Device_SCL) // Pin defines // Configure Device as Master 41
