標(biāo)題: 單片機(jī)控鍵切換花樣流水燈，用定時(shí)器作定時(shí)。求思路
大神們，可以說一下思路嗎？

作者: wosiyabo 時(shí)間: 2017-3-27 01:07
那我就說一下思路吧。先定義變量num；
流燈樣式放在數(shù)組內(nèi)
比如：TAB1[]={0x01,....0xFF};
TAB2[]={0x04,....0xF5};
主程序做按鍵掃描選擇那一個(gè)數(shù)組，然后if(num==0)送數(shù)組去IO腳,并且數(shù)組內(nèi)容++；
定時(shí)器10MS內(nèi)做計(jì)數(shù)num++，加至100后，num=0;

頂起來

作者: imxuheng 時(shí)間: 2017-3-27 09:58
可以把流燈樣式數(shù)據(jù)放到EPPROM里，運(yùn)行時(shí)每隔一段時(shí)間（可用定時(shí)器來實(shí)現(xiàn)）從EPPROM里讀數(shù)據(jù)賦給IO腳。假設(shè)每種樣式數(shù)據(jù)長度一致，都為L，每監(jiān)聽到按鍵按下，跳過L長度的數(shù)據(jù)后讀取流燈樣式數(shù)據(jù)賦給IO腳
