關(guān)于 ISD4002 語音錄放的原程序,前段時間搞了好久,結(jié)果是自己搞的太亂了,現(xiàn)在這個程序是調(diào)試好的,現(xiàn)在已經(jīng)在做了,不過是51的,大家改下就可以用在 PIC 上了,因為我沒有檫寫芯片,市場也沒找到,就買了個 89C2051試 了.

;4002-120 錄音程序 （不分段一次性錄完直到 OVF標(biāo)志----指示ISD的錄、放操作已到達(dá)存儲器的未尾。結(jié)束） ; this is a basic recore and play programe if you want add other control plaease do it yourself. by LINPO Andy Tks !
