1. Function description

    1, ATIM1 triggers DAC1 to generate a sawtooth wave, with a reset value of 0x000 and a step value of 60.

2. Development environment

    Software development environment: KEIL MDK-ARM V5.34
                                      IAR EWARM 8.50.1 
    Supported chips:
        N32H730  
        N32H735   
        N32H735EC
        N32H760
        N32H762
        N32H765
        N32H765EC
        N32H785
        N32H785EC
        N32H787

3. How to use
   System Configuration:
        1. Clock source: HSI+PLL
        
        2. System Clock frequency: 
            M7 Core：600MHz 
            
        3. Port configuration:
            PA4 is selected as analog function DAC1 OUT

        4. DAC:
            DAC1 selects the step trigger source "DAC_Trigger_ATIM1_TRGO", and the reset trigger source for DAC1 is "DAC_Trigger2_Software".
            The increment sawtooth step value is 60 and Reset value is 0x000.
     
Usage:
        1, After compiling, download the program  and reset, open the debugging mode and observe the output waveform of PA4 using an oscilloscope
        2. When running at full speed, you can see the increasing sawtooth wave output from PA4.
