1. Typical application of the timer control, to understand the role of the corresponding register and programming applications 2. To understand the structure and TMS320F2812 interrupt interrupt processing. 2. Experimental device 1. PC machine, the operating system is WindowsXP (or Windows98, Windows2000), installed ccs3.1 2. TI 2000 Series TMS320F2812 eZdsp development board 1 3. Extended test case one. 3. Experimental Principle 1. TMS320F2812 device has three 32-bit timer (Figure 3.1) (TIMER0/1/2). CPU Timer 1 and 2 reserved for the system (such as DSP-BIOS) to use, CPU Timer 0 can be used in user application. In F2812 chip, the timer interrupt signal (TINT0, TINT1, TINT2)
