一. 簡介

mipi屏調(diào)試一般都要在RK平臺(tái)的dts中配置屏幕上電初始化時(shí)序：panel-init-sequence和下電初始化時(shí)序：panel-exit-sequence。本文講解如何配置屏幕的這些初始化時(shí)序。
專欄總目錄

二. 數(shù)據(jù)類型：Data Type

2.1 常見數(shù)據(jù)類型 1 ：DCS Write

注意：這里的parameter并不是指數(shù)據(jù)字節(jié)個(gè)數(shù)

0x05 命令類型: 單字節(jié)數(shù)據(jù)    (DCS Short Write, no parameters)
0x15 命令類型: 雙字節(jié)數(shù)據(jù)    (DCS Short Write, 1 parameter)


0x39 命令類型: 多字節(jié)數(shù)據(jù)    (DCS Long Write, n parameters n > 2)

0x05 命令類型：(DCS Short Write, no parameters)

05 95 01 11
05 95 01 29

0x15 命令類型：(DCS Short Write, 1 parameter)

15 00 02 80 77
|  |  | |  |
|  |  | |  數(shù)據(jù)
|  |  | | 寄存器地址
|  |  數(shù)據(jù)長度
|  延時(shí)
命令類型（0x05: 單字節(jié)數(shù)據(jù) 0x15: 雙字節(jié)數(shù)據(jù) 0x39: 多字節(jié)數(shù)據(jù)）
	
解析：
Data Type：0x15       ( 0x15格式的數(shù)據(jù)類型 DCS Short Write, 1 parameter)
Delay：0x00           ( 延時(shí)，表示當(dāng)前 Packet 發(fā)送完成之后，需要延時(shí)多少 ms，再開始發(fā)送下一條命令 )
Payload Length：0x02  ( Packet 的有效負(fù)載長度為2 Bytes，數(shù)據(jù)字節(jié)個(gè)數(shù)為2 )
Payload: 0x80 0x77    ( Payload 數(shù)據(jù) )

0x39 命令類型是帶多個(gè)參數(shù),大于兩個(gè)參數(shù) (DCS Long Write / write_LUT Command Packet)

39 00 06 FF 77 01 00 00 10
39 00 03 C0 63 00
39 00 03 C1 11 02

2.2 常見數(shù)據(jù)類型 2 ：Generic Write

注意：這里的parameter并不是指數(shù)據(jù)字節(jié)個(gè)數(shù)

0x03 命令類型：  單字節(jié)數(shù)據(jù) (Generic Short Write, no parameters)
0x13 命令類型：  雙字節(jié)數(shù)據(jù) (Generic Short Write, 1 parameter)


0x23 命令類型：  三字節(jié)數(shù)據(jù) (Generic Short Write, 2 parameters)


0x29 命令類型：  多字節(jié)數(shù)據(jù) (Generic Long Write, n parameters n > 2)

三. RK平臺(tái)上電初始化時(shí)序配置

屏廠給的MIPI屏初始化代碼：

params- >dsi.vertical_sync_active=2
params- >dsi.vertical_backporch=10
params- >dsi.vertical_frontporch=14
params- >dsi.horizontal_sync_active=24
params- >dsi.horizontal_backporch=80
params- >dsi.horizontal_frontporch=60
params- >dsi.PLL_CLOCK=478
 
LCD_nReset=1;
Delayms(5);
LCD_nReset=0;
Delayms(20);//10
LCD_nReset=1;
Delayms(200);//120

3.1 分析客戶給的mipi屏初始化代碼：

Generic_Short_Write_1P(0xBA,0x8F);

Generic_Short_Write_1P表示：發(fā)送Generic命令，帶1個(gè)參數(shù)，數(shù)據(jù)字節(jié)個(gè)數(shù)為2(Generic Short Write, 1 parameter)
0xBA：寄存器地址
0x8F：數(shù)據(jù)1為0x8F

在DTS上轉(zhuǎn)成RK上的mipi屏初始化格式

13 00 02 BA 8F

解析：
13 表示0x13數(shù)據(jù)類型的指令
00 表示沒有延時(shí)
02 表示兩個(gè)數(shù)據(jù)長度 ：0xBA,0x8F
BA 表示寄存器地址0xBA
8F 表示0x8F這個(gè)數(shù)據(jù)

分析客戶給的mipi屏初始化代碼：

DCS_Short_Write_NP(0x11);	
 Delay(200);
 DCS_Short_Write_NP(0x29);
 Delay(50);
 
 解析：
 DCS_Short_Write_NP表示：只發(fā)送DCS命令，不帶參數(shù)，數(shù)據(jù)字節(jié)個(gè)數(shù)為1。(DCS Short Write, no parameters)
 0x11：數(shù)據(jù)1為0x11
 Delay(200)：延遲為200

在DTS上轉(zhuǎn)成RK上的mipi屏初始化格式

05 C8 01 11
05 32 01 29

解析：
05 表示0x05數(shù)據(jù)類型的指令
C8 表示延時(shí)為200 轉(zhuǎn)換成16進(jìn)制為0xC8
01 表示1個(gè)數(shù)據(jù)長度 ：0x11
11 表示數(shù)據(jù)：0x11

3.2 將屏廠的初始化代碼轉(zhuǎn)換成RK平臺(tái)的屏幕上電初始化時(shí)序DTS配置：
