在给定的code中,什么是正确的采样频率(采样率)?是8kHz吗?我找不到它。
答案 0 :(得分:0)
此评论建议8kHz
.equ TIMECONST, #32000 ;Use 32000 samples (4 seconds) as constant to find peak
代码的这一部分具体说" 8KS / s"
;Setup Timer 1 for sampling delay: Tcy = 16MHz (64MHz Clock)
mov #0x8000,w1 ;8KS/s at Tcy=16MHz
mov w1,T1CON ;1:1, Int Clk, ON
mov #2000,W1 ;Load PR1 for delay, 8KS/s Sample Rate @16MHz Internal
mov w1,PR1
