三、接入PICkit3燒錄時(shí)要設(shè)置電源
四、maplab的輸出窗口看不見
Mplab X IDE的使用
一、接入PICkit3提示找不到工具，為驅(qū)動(dòng)沒有安裝
二、microchip官網(wǎng)下載XC8編譯器
實(shí)踐
一、端口控制
二、實(shí)現(xiàn)觸摸功能
三、使用PIC公司的觸摸庫做觸摸處理
C與匯編混合編程
--------------------------------------------------------------------------------------------------------------
看到PIC單片機(jī)就感到親切，今天開始對(duì)PIC16lf1936編程仿真，仿真器PICKIT3。
--------------------------------------------------------------------------------------------------------------
Mplab IDE的使用
一、接入PICkit3出現(xiàn)Target Device ID (00000000) does not match expected Device ID (00002460)
這是仿真頭與線路板連接不正確。
二、首次使用pickit3出現(xiàn)PK3Err0040
PK3Err0040: The target device is not ready for debugging.Please check your configuration bit settings and program the device before proceeding.
解決辦法：在這里勾 選：Debugger>Settings>Program Memory>Automatically 的 “Program after successful build”項(xiàng)即可在每次成功后自動(dòng)下載代碼到Flash并進(jìn)入調(diào)試就緒模式。
三、接入PICkit3燒錄時(shí)要設(shè)置電源
PK3Err0045: You must connect to a target device to use PICkit3.
Programmer>Settings>Power中設(shè)置
四、maplab的輸出窗口看不見
1、在設(shè)置這個(gè)功能的時(shí)候，準(zhǔn)備把output窗口移到下邊緣，沒想到移動(dòng)過頭，移動(dòng)到電腦桌面的最下方（移到下發(fā)看不到的位置去了），然后output窗口就不見了，調(diào)不出來，在view里面勾選了output或者取消，編譯文件，甚至重新啟動(dòng)電腦，output窗口都不出現(xiàn)了！
右擊任務(wù)欄－>解除鎖定任務(wù)欄－>拖動(dòng)任務(wù)欄到右邊就可以看到被隱藏的窗口了
2、隱藏在整個(gè)窗口的下方
右側(cè)是有進(jìn)度條的。
將output移上去，右側(cè)就沒有進(jìn)度條了。
--------------------------------------------------------------------------------------------------------------
Mplab X IDE的使用
圖1 驅(qū)動(dòng)切換與安裝
圖2 批量燒錄
一、接入PICkit3提示找不到工具，為驅(qū)動(dòng)沒有安裝
打開如圖1 MPLAB drive，如下圖設(shè)置，點(diǎn)"Apply Changes"即可。
二、microchip官網(wǎng)下載XC8編譯器
--------------------------------------------------------------------------------------------------------------
實(shí)踐
一、端口控制
完成三件事：１、仿真部分全部正常；２、配置字設(shè)置無誤；３、內(nèi)部晶振正常，端口操作正常
