1、关于MPLAB的问题关于MPLAB的问题JayWong19882021-12-08各位大神好，我是一个加拿大的电子系的留学生，我有一个实验需要写一个MPLAB的单机片，我硬件已连接显示屏，keypad，LM60温度感应器，我用的IC是p24HJ128GP502，我的C语言编程不是太好，所以请各位大神帮帮我吧！它的要求如下：我怎样在whileloop里添加一下的功能呢？1.上电自检。红色LED闪烁三次。好的消息。2.显示选项:1)读取，2)保存，3)召回和4)去除。3.要求选择按1，读取传感器读数并在LCD上显示读数。4.眨了一次。按2保存传感器读数，并确认保存在LCD上。5.眨了两次。按3来回
2、忆一个保存的浏览。询问浏览数字。6.按4去除不保存的读数。7.眨了一次。完成任何选择后，返回到显示选项屏幕。这是我的代码，我尝试了把它的要求写进去，但都失败。#includepic24_all.h#includestdio.h#defineRS_HIGH()(_LATB9=1)#defineRS_LOW()(_LATB9=0)#defineCONFIG_RS()CONFIG_RB9_AS_DIG_OUTPUT()#defineRW_HIGH()(_LATB13=1)#defineRW_LOW()(_LATB13=0)#defineCONFIG_RW()CONFIG_RB13_AS_DIG_OU
