標(biāo)題: PIC單片機(jī)存儲(chǔ)不足問題
用的單片機(jī)型號(hào)為PIC12F1571,代碼大概300多行，刪掉一個(gè)調(diào)用的比較多的函數(shù)之后，能編譯成功，用的MPLAB X IDE5.05,XC8(v2.30)

光刪除子函數(shù)不刪除主函數(shù)里的調(diào)用會(huì)報(bào)錯(cuò)的，因?yàn)樗也坏搅�，刪除了不能保證程序的完整性還能用嗎，只能精簡(jiǎn)部份，或者用外部存儲(chǔ)，比如24C系列
作者: Y_G_G    時(shí)間: 2021-12-16 12:43
程序內(nèi)存不夠你就刪除函數(shù)?那要這函數(shù)來干嘛?
難道你是復(fù)制別人的代碼嗎?
PIC的編譯環(huán)境很難搞,報(bào)錯(cuò)的話,你很多時(shí)候是不會(huì)像Keil那樣能找到的
你只有嚴(yán)格按照C語言標(biāo)準(zhǔn)來寫

下面的報(bào)錯(cuò)，我復(fù)制百度之后，是因?yàn)榇鎯?chǔ)不夠的原因，如果我不用那個(gè)調(diào)用的函數(shù)程序功能就實(shí)現(xiàn)不了了，精簡(jiǎn)的話以我目前的水平已經(jīng)到了極限了，代碼真的很簡(jiǎn)單了，感謝您的建議，我會(huì)再去嘗試精簡(jiǎn)代碼的

這些錯(cuò)誤表示ROM （=閃存）內(nèi)存不足。
這意味著正在使用的 PIC 的代碼太多

沒錯(cuò)，是這個(gè)原因
我將void get_pwm_data(void)函數(shù)中的大字節(jié)變量乘除法屏蔽之后，編譯能通過
/*  kk = ((uint32_t)kk / (uint32_t)power_voltage);
      
        kk = ((uint32_t)kk * (uint32_t)16 / (uint32_t)10) + ((uint32_t)power_voltage / 90); //34W

我把所有常數(shù)的乘除法運(yùn)算算好之后，再寫入代碼，就可以編譯成功了，感謝大佬
