STC8a8k64S4A12怎么實(shí)現(xiàn)流水呼吸燈？只有呼吸燈的PWM代碼，現(xiàn)在想實(shí)現(xiàn)8個(gè)燈呈現(xiàn)波浪式的起伏，也算是流水呼吸燈了
求助大佬們，非常非常感謝!

復(fù)制代碼
這個(gè)代碼是定義了一個(gè)燈，多個(gè)燈定義加上PWM1、2...即可

呼吸燈函數(shù)可以帶入口參數(shù)，然后采用輪詢(xún)的方式把每個(gè)等賦值給入口參數(shù)即可。

可以不用PWM中斷去做。我做過(guò)一個(gè)呼吸燈產(chǎn)品，思路是：用定時(shí)器定時(shí)一個(gè)1ms的中斷，然后根據(jù)時(shí)間去改變A的PWM占空比，比如20ms改變一次,當(dāng)A的占空比從0到100%再遞減到30%時(shí)，你開(kāi)始遞加B的PWM的占空比，當(dāng)A的占空比0的時(shí)候，B的占空比就在30%，類(lèi)比下去C,D,E等等。我做的不是海浪，不過(guò)你可以根據(jù)海浪的特性去做。

手上沒(méi)有STC8A的單片機(jī)
試試這樣改

static char delay_on_i = 0;
if(!delay_on)
{
delay_on = 1500;//~0.5sec
if(delay_on_i<8)
{
Enb[delay_on_i] = 1;
delay_on_i++;
}
}else{
delay_on--;
}
if (PWMCFG & 0x80)
{
PWMCFG &= ~0x80; //清中斷標(biāo)志
for(index = 0;index < 8; index++)
{
if(Enb[index])
{
if (!dir[index])
{
val[index]++;
if (val[index] >= CYCLE) dir[index] = 0;
}
else
{
val[index]--;
if (val[index] <= 1) dir[index] = 1;
}
}
}
