程序：太陽(yáng)能控制器充電模塊
硬件：本程序適用12V/24V 20A V1.0
作者：
日期：
基本功能表述：
1、只有充電功能
2、額定電壓： 12V/24V鉛酸電池自動(dòng)識(shí)別?
3、提升充電電壓：14.6V/29.2V
4、直充充電電壓：14.4V/28.8V
5、浮充充電電壓: 13.6V/27.2V
7、超壓電壓： 17V/34V
8、欠壓： 12V/24V
9、過(guò)放: 11.1V/22.2V
10、溫度補(bǔ)償范圍 -5 --- 55 °，僅對(duì) 充電返回，提升充電，直充，浮充進(jìn)行補(bǔ)償
11、使用內(nèi)部 16M RC振蕩器，2分頻，8Mhz運(yùn)行，對(duì)于時(shí)間要求不嚴(yán) ，可使用內(nèi)部RC，如果對(duì)時(shí)間要求很高，則使用外部8M晶振
12、額定電流 20A
修改記錄：
修改LED的指示功能
1. 1號(hào)燈，綠燈，不接太陽(yáng)能板或者黑夜時(shí) 不亮，接上太陽(yáng)能電池板，有光照時(shí) 常亮。
2. 2號(hào)燈綠燈，開(kāi)始充電后，閃爍；不充電不亮。
3. 3號(hào)燈綠燈，電壓達(dá)到正常電壓后，常亮，低于標(biāo)準(zhǔn)電壓后閃爍。
4. 4號(hào)燈紅燈，電池降低到最低電壓后紅燈常亮，高于最低電壓熄滅。
修改PWM_BAT初始化時(shí)的狀態(tài)，有原來(lái)的初始=0，改為初始化=1，以關(guān)閉對(duì)應(yīng)MOS管
