CCS C Compiler Manual PCB / PCM / PCH

Relevant getenv() parameters:
UART
AUART
UART_RX
UART_TX
UART2_RX
UART2_TX
Returns the number of UARTs on this PIC
Returns true if this UART is an advanced UART
Returns the receive pin for the first UART on this PIC (see
PIN_XX)
Returns the transmit pin for the first UART on this PIC
Returns the receive pin for the second UART on this PIC
TX – Returns the transmit pin for the second UART on this
PIC
Example Code:
/* configure and enable uart, use first hardware UART on PIC */
#use rs232(uart1, baud=9600)
/* print a string */
printf(“enter a character”);
/* get a character */
if (kbhit())
c = getc();
//check if a character has been received
//read character from UART
RTOS
These functions control the operation of the CCS Real Time Operating System (RTOS). This
operating system is cooperatively multitasking and allows for tasks to be scheduled to run at
specified time intervals. Because the RTOS does not use interrupts, the user must be careful to
make use of the rtos_yield() function in every task so that no one task is allowed to run forever.
Relevant Functions:
rtos_run()
rtos_terminate()
rtos_enable(task)
Begins the operation of the RTOS. All task management
tasks are implemented by this function.
This function terminates the operation of the RTOS and
returns operation to the original program. Works as a
return from the rtos_run()function.
Enables one of the RTOS tasks. Once a task is enabled,
the rtos_run() function will call the task when its time
occurs. The parameter to this function is the name of task
