DAC在roteus中软件仿真生成波形矩形,三角,锯齿,正弦

1、1. 电路图2. 锯齿波3. 三角波 4矩形波 5. 正弦波 6.C 代码 #include #include #define DAC0832 XBYTE0x7fff #define uchar unsigned char #define uint unsigned int / 生成波形期间对应的按键要一直按下 sbit key 仁 P1A0;sbit key2=P1Al；sbit key3=P1A2; sbit key4=P1A3； / 下面的编码定义是由 正弦波数据生成器 所生成，可以百度下载 uchar code sin_tab=0x7F,0x82,0x85,0x88,0x8B,0x8F
