8*32點陣STC89c51測溫代碼改用stc12c5a60s2代態(tài)測溫顯示亂碼

ID:17109 · 發(fā)表于 2019-6-1 11:04

這個是用89c51的測溫代碼想改用 stc12c5a60s2代態(tài),不知什么原因  就出現(xiàn),測溫顯示亂碼有這放面的師博嗎幫忙看看程序有什么問題,修改上傳看看謝謝

查看芯片參數(shù)修改相關(guān)程序

ID:511890 · 發(fā)表于 2019-6-1 16:04

應(yīng)該是延時程序的問題。89系列一個機(jī)器周期等于12個時鐘周期(RD+的是6個時鐘周期)。而12系列的單片機(jī)一個機(jī)器周期等于1個時鐘周期。換一個延時函數(shù)試試。這個延時你可以在ISP燒錄工具中選擇相應(yīng)的芯片生成。

ID:552667 · 發(fā)表于 2019-6-1 20:26

芯片不一樣定時器中斷也不一樣 12的速度好像是51的1200倍吧

ID:155507 · 發(fā)表于 2019-6-1 20:58

換一個延時函數(shù)試試。

void delay_ms(uint16 x)
{
uint16 j,i;
for(j=0;j<x;j++)
{
for(i=0;i<1100;i++);
}
}

師傅能上傳上面這條代碼的，打包好的源程序嗎謝謝！

要仔細(xì)研讀生產(chǎn)商提供的Data Sheet，清楚二者的軟硬件差別，并將程序作對應(yīng)的調(diào)整；從最簡單處著眼，應(yīng)比對二者腳位PIN OUT的差別。可從STC網(wǎng)站獲得Data Sheet文件
