Assembly code for flashing the Stellaris Launchpad LED

	.text

	.word 0x2000000 // Initial stack pointer
	.word start + 1 // Address of the reset vector '+ 1' denotes THUMB instructions vs ARM instructions.

	start:

	mov r0, #0x00 // Loads 0x00 into register r0
	mov r1, #0xFF // Loads 0xFF into register r1

Adding two numbers using ARM assembly

	// Assembly generally has three sections in the source
	// .text - This is where all of the code lives (Flash)
	// .data - This is where all variables with value go (RAM)
	// .bss - This is where uninitialized variables go (RAM)
	//
	// Since this program is super simple I just used the .text section
	.text

	.word 0x20000000 // (address 0x0000.0000) This initializes the stack pointer
	b start + 1 // (address 0x0000.0004) This instructs the CPU to branch to start at reset
