AT89C2051ISD2560
- 目前基于单片微机的语音系统的应用越来越广泛,如电脑语音钟、语音型数字万用表、手机话费查询系统、排队机、监控系统语音报警以及公共汽车报站器等等。本文作者用Flash单片机AT89C2051和录放时间达60s的数码语音芯片ISD2560设计了一套智能语音录放系统,实现了语音的分段录取、组合回放,通过软件的修改还可以实现整段录取,循环播放,而且不必使用专门的ISD语音开发设备。-current microcomputer-based voice systems are widely used, suc

PWM
- PWM调光具有以下优点: (1)无论调光比有多大,LED-直在恒流条件下工作。 (2)颜色一致性好,亮度级别高。在整个调光范围内,由于LED电流要么处于最大值,要么被关断,通过调节脉冲占空比来改变LED的平均电流,所以该方案能避免在电流变化过程中出现色偏。(3)能提供更大的调光范围和更好的线性度。-PWM dimming has the following advantages: (1) no matter how much the dimming ratio is, LED- is
