CC3200 Project Specifics

Stack and Heap Sizes

The default stack and heap sizes are set to be 1024 and 1024 bytes by default when a project is created.

Target Startup Code

The startup code CC3200_Startup.s is common to all CC3200_Startup processors. There are a set of preprocessor defines that configure the startup code and are documented in the startup file itself. The startup code calls out to a weak symbol SystemInit with the stack pointer set to the top of of SRAM. The SystemInit function can be used to set the CPU clock or configure any external memories prior to the C initialisation code as such it cannot access initialised static data.

Target Reset Script

The reset script CC3200_Target.js is used by the debugger to reset the target board.

CMSIS support

CMSIS header files are referenced as part of the new project setup. The Texas Instruments driverlib files are supplied.

CTL support

The file ctl_CC3200.c implements the CTL system timer using the standard Cortex-M SysTick timer. The timer is configured to interrupt at approximately a 10 millisecond rate and increment the CTL system timer by 10 to give a millisecond timer.

The CTL interrupt support functions ctl_global_interrupts_set, ctl_set_priority, ctl_unmask_isr and ctl_mask_isr are implemented in this file. The implementation uses the lowest half of the available NVIC priorities (top bit set in the priority) for CTL interrupts.
