Abstract

A method for sending MIPI module single picture control codes disclosed by the present invention comprises the following steps, step 1: edit and save the control code file in the single picture parameter editing interface of the host computer; step 2: execute the When the single-frame switching action is described, the host computer parses the control code file of the single frame into hexadecimal data that the image signal generator can recognize and encapsulates it into UDP packets according to the protocol that the image signal generator can recognize; Step 3: Send the encapsulated UDP data packet to the MIPI module to be tested through the image signal generator. The invention can be flexibly compatible with the control code distribution requirements of various types of MIPI modules, and can reduce the number of versions and the number of upgrades of the single-chip microcomputer program of the image signal generator.

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 (Mobile Industry Processor Interface, 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 th...

Embodiment

[0034] Example: convert the power supply information "RBA 05 C0 E0 62 D3 81 35 3C 01 06, Delay100ms" of a single frame into hexadecimal data that can be recognized by the single-chip microcomputer in the image signal generator: convert "RBA 05 C0 E0 62D3 81 35 3C 01 06" is converted into "0x39 0xBA 0x0A 0x05 0xC0 0xE0 0x62 0xD3 0x81 0x350x3C 0x01 0x06", "0x39" tells the MCU what type of instruction to issue parameters, 0xBA is the register address, 0x0A is the length of the data behind, The next 10 bytes are the data content; convert "Delay 100ms" to "0x000x00 0x02 0x64 0x00", "0x00 0x00 0x02" tells the MCU to perform the delay operation, and the following bytes indicate 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...
