1、基于基于TFTLCD的指針式時(shí)鐘設(shè)計(jì)的指針式時(shí)鐘設(shè)計(jì)摘要自時(shí)鐘發(fā)明的那天起，它就注定了與人們有著密不可分的關(guān)系，但科學(xué)技術(shù)在不斷發(fā)展，人們隨著時(shí)間的推移對(duì)時(shí)間計(jì)量的精度要求越來(lái)越高，機(jī)械式時(shí)鐘也越來(lái)越滿足不了人們?nèi)找嬖龈叩囊罅恕Ｈ《氖戮哂懈叨葴?zhǔn)確性和直觀性且無(wú)機(jī)械裝置，使用壽命更長(zhǎng)更長(zhǎng)等優(yōu)點(diǎn)的電子時(shí)鐘。電子時(shí)鐘更具人性化，更能提高人們的生活質(zhì)量，更受人們歡迎，機(jī)械時(shí)代已經(jīng)遠(yuǎn)去，電子時(shí)代已經(jīng)到來(lái)。因此本設(shè)計(jì)是基于ATMEL公司的A

2、Tmega128單片機(jī)開發(fā)平臺(tái)實(shí)現(xiàn)一種高精度，智能化的指針式時(shí)鐘系統(tǒng)采用單片機(jī)與時(shí)鐘芯片DS1302設(shè)計(jì)電子時(shí)鐘時(shí)通常是數(shù)字顯示這是由于選用數(shù)碼管和1602等器件的顯示能力有限。而12864是基于點(diǎn)陣式的液晶屏其像素點(diǎn)為12864但12864自身像素較低使其顯示指針式時(shí)鐘效果遠(yuǎn)低于1.8寸TFTLCD液晶但兩者所基于的原理相同。因此本設(shè)計(jì)采用ATmega128單片機(jī)為控制核心，輔以DS1302時(shí)鐘采集系統(tǒng)，1.8寸TFTLCD液晶作為顯
