mtk chipset

Recently, customers asked to use the MTK 6572 chip via USB OTG add support wired network card, I checked all the hooks and hooks all the site, there is no relevant discussion, see the MTK to the data, including FAQs, only said to support the USB OTG keyboard and mouse and USB stick. What to do? I'm the only one who comes.However, according to my understanding of the USB device mechanism, as long as we hang

question that needs to complete the strcmp function. The existing functions in C cannot be used. There are many similar questions on the Internet.Use custom functions to implement strcat, strcpy, strcmp, strlen, and strlwr functions. 1. strcatVoid MyCat (char * S1, char * S2){While (* S1 ++ );S1 --;While (* S1 ++ = * S2 ++ );}2. strcpyVoid mycpy (char * S1, char * S2){While (* S1 ++ = * S2 ++ );}3. strcmpInt mycmp (char * S1, char * S2){For (; * s = * t; s ++, t ++)If (* s = 0) return 0;Return

The MTK platform has been well supported by some carrier's network lock requirements. The vast majority of overseas requirements can be achieved by directly configuring relevant files. Here, we will briefly describe the configuration method without analyzing the principles.Related Data Structure Analysis: The data structures related to the SML lock network configuration in modem include: Sml_context_struct: SML context, Cat: SML type,

MTK chip Data Daquan, MediaTek's various models of chip data are:The other does not say, directly may be clear: The picture does not know why not show.Download Link: https://bbs.usoftchina.com/forum-238-1.htmlThese information are all the small partners to share and collected, dare not say that all of the MTK chip data have, but most of them are here, the model is also many, need to add our AC Q Group: 8132

MTK timer Summary There are many types of MTK tiemr, from the underlying KAL to MMI, there are timer figures. KAL timer KAL timer is a very underlying timer. Its implementation is to directly encapsulate the timer of mtk rtos (nuleus). The implementation method is HISR, Therefore, this timer has a high priority, that is, when this timer times out, it will trigger

MT6735 platform, can boot, but the black screen for a long time to see the boot picture.Check the serial port log found that the phone is normal operation, that is, LCM driver is not abnormal, black screen stage is not any error reported.Find the following on the MTK FAQ:[DESCRIPTION]This FAQonly discuss the black screen during boot, do not discuss the flower screen (can refer to the brush). Only the l/m version is discussed (the previous version of K

MTK NAND Flash configuration Support1. First confirm the Flash model, for example: SanDisk sd7dp24c_4g. 2. View Mediatek/build/tools/emigen/mt6572/memorydevicelist_ Mt6572.xls whether there is support for the chip, if not supported, you can go to the MTK official website to download the latest Memorydevicelist_mt6572.xls files. 3. Modify the Mediatek/custom/project_name/preloader/inc/custom_memorydevice.h f

Original address: Andorid Camera Drive process--MTK platform waiting for the heartCamera Imaging principle:The scene is produced by the lens of the optical image projected onto the sensor surface, and then converted to analog electrical signals, after the digital mode into the image signal, processed by the DSP, and then transmitted through the IO interface to the CPU processing. Since the camera satisfies the bus, drive, and device model, look at how

Introduction As mobile devices become more intelligent and the hardware leaps forward, the power consumption is getting bigger and bigger. The result is a one-day stop. However, the current battery technology is still in progress, so we can only respond to the national call to start from "Energy Conservation and emission reduction. The display screen has always

Mtkuses the ref_list.txt file to uniformly load characters for conversion Convert the GB code to unicode encoding, because the MTK system only accepts unicode encoding for character function APIs! Below I want to introduce two methods to directly output the GB code! Method 1: We can use the file conversion. the function mmi_chset_text_to_ucs2 (...) in the C file (....) the function is used to convert a string encoded in GB. However, the macro _ mmi_c
