[0034] 实施例:将单幅画面的电源信息“RBA05C0E062D381353C0106,Delay100ms”转换成图像信号发生器中的单片机能识别的十六进制数据:将“RBA05C0E062D381353C0106”转换为“0x390xBA0x0A0x050xC00xE00x620xD30x810x350x3C0x010x06”,“0x39”告知单片机以何 Parameters issued by different types of instructions, 0xBA is the register address, 0x0A is the length of the data behind, and the next 10 bytes are the data content; convert "Delay100ms" to "0x000x000x020x640x00", and "0x000x000x02" tells the MCU to perform the delay operation , the following byte indicates the delay time.

[0035] In the above scheme, the protocol used to encapsulate the hexadecimal data into a UDP packet is defined as follows: the first 2 bytes of the protocol are protocol command words 0x02, 0x50, the 3rd byte and the 4th byte is the length of the data packet, the 5th byte and the 6th byte are the total length of the hexadecimal data, the 7th byte and the 8th byte are the data in the data packet in the said hexadecimal data The starting byte in , the 9th byte to the 251st byte i...

Abstract

The invention discloses a method for transmitting an MIPI module single-picture control code. The method comprises the following steps: 1. editing and saving a control code document in a single-picture parameter editing interface of an upper computer; 2. when executing a single-picture switchover action, parsing the single-picture control code document into hexadecimal data which is recognizable to an image signal generator by virtue of the upper computer and encapsulating the hexadecimal data into a UDP data packet according to a protocol recognizable to the image signal generator; and 3. issuing the encapsulated UDP data packet to a to-be-determined MIPI module by virtue of the image signal generator. According to the method disclosed by the invention, the demands of issuing the control codes of various types of MIPI modules can be combined flexibly, so that the version quantity and the upgrading times of single chip programs of the image signal generator can be reduced.

Description

technical field [0001] The invention belongs to the technical field of display module detection, and in particular relates to a method for sending MIPI (MobileIndustryProcessorInterface, mobile communication industry processor interface) display module single-frame control codes. Background technique [0002] At present, MIPI modules in some production lines need to perform some special tests after lighting up, such as testing power consumption in sleep mode, etc., and need to issue control codes in real time during the process of cutting pictures. The implementation process is through The host computer writes a series of data (such as power supply settings, common voltage settings, timing settings, module identification numbers, gamma parameters, etc.) to the registers of the MIPI module, and then sends them to the display module. The control codes corresponding to different types of MIPI modules are different, and the control codes corresponding to different tests of the s...
