Embodiment
The present invention will be further described below in conjunction with drawings and Examples, but should not limit protection scope of the present invention with this.
The inventive method mutual by with PC side software instrument and mobile phone side serial ports, modification is stored in the flag bit that mobile phone flash memory (flash) is gone up the fixed position, read the flag bit of this position in the start process, judge concrete LCD chip for driving model according to flag bit, model is loaded into the LCD driving function of respective type on the corresponding overall situation function pointer in view of the above, so just can carry out compatibility, accomplish the LCD display part that same softwarecompatible is different different LCD chip for driving.
Fig. 1 is the frame diagram of the method for the different display screens of handset compatibility of the present invention.PC utilizes common Serial Port Line by UART Universal Asynchronous Receiver Transmitter (UART, Universal AsynchronousReceiver/Transmitter) links to each other with mobile phone hardware, this mobile phone uses base band integrated circuit (BBIC), base band integrated circuit and liquid crystal display drive circuit (LCD Driver IC) transmit by parallel 16 bit data bus (D0--D15) and drive order and video data, make normal display action with correct control 1cd.Utilize PC side software instrument and the interprogram communication of mobile phone side, thereby realize the transmission of valid data.
Fig. 2 is the flow chart of the inventive method.The concrete grammar step is as follows:
Step 1: unified in the list of sequence numbers of the standard of LCD display part row of usefulness, follow-up have an interpolation of can postponing of new display device.
List of sequence numbers can be listed according to the Different L CD display device of concrete use, as, the LCD that producer one produces can determine that sequence number is 0x01, the LCD that producer two produces can determine that sequence number is 0x02, and the like, such sequence number table should strict control sequence number determine, otherwise can cause follow-up maintenance and produce take place chaotic, table specific as follows:
Table 1 LCD display part sequence number table
| The LCD of producer one | ?0x01 |
| The LCD of producer two | ?0x02 |
| The LCD of producer three | ?0x03 |
Step 2: for can dynamically pointing to the function pointer of concrete function, this drive actions comprises initialization, desired location, enters dormancy, goes out dormancy, shutdown, contrast control with the associated drives of LCD action unified Definition.
Step 3: the space of opening up a byte for LCD on mobile phone flash flash memory is used for the storage mark position separately.
Step 4: according to the standard sequence of appointing in the step 1 number tabulation, by PC side software instrument, the fixed storage space of opening up on flash writes the corresponding flag bit with used LCD.
Step 5: after handset starting is finished, flag bit is read in the fixed position of the flash that opens up from step 3, in standard sequence number tabulation, mated, found corresponding LCD driving function, the function pointer that defines in the step 2 is pointed to corresponding LCD driving function.
Step 6: utilize described liquid crystal display device driving function to this liquid crystal display device initialization, and the chip for driving of operating this liquid crystal display device is correctly controlled the demonstration of this liquid crystal display device.
PC side software in the described step 4 is meant the tool software that moves on PC, be used for the mobile phone of supporting compatible Different L CD scheme is sent the order of dirty bit.This tool software is realized data are transferred to mobile phone from the PC side by the UART interface that calls the windows bottom.
This tool software uses Microsoft Visual C++6.0 exploitation, can move in the Windows system.The software major function is that according to the rules form carries out communication by UART mouth and mobile phone, revises the order of LCD flag bit by sending, and receives and resolve the response results of mobile phone to order, provides and sends the prompting of ordering successfully or failing.
Software flow pattern is seen accompanying drawing 3.Key step is as follows:
1, PC side tool software interface provides the selection of UART mouth, LCD type selecting, LCD sign write activity button button interfaces, and the user has selected can to click the button button after corresponding UART mouth and the LCD type and carried out write operation.
2, the PC side software is opened PORT COM according to the UART mouth of selecting and is connected with mobile phone, sends to the order of mobile phone according to the LCD type package of selecting, and by the UART mouth, this order is sent to mobile phone.
3, wait for the order of mobile phone feedback modification LCD sign action success or not, if not, change step
4; If change step 5.
4, provide prompting: mobile phone is response not.Change step 7.
5, mobile phone feeds back to the PC side software by the UART mouth with LCD sign modification result.
6, the PC side software is according to the situation of mobile phone feedback, the state of display update LCD flag bit success or not.
7, finish.
Main source code is as follows:
If (! ConnectPS (COMPort)) // connect mobile phone by the UART mouth
{
If (! Connec tPS (COMPor t)) // once failure is tried again
{
StateDi splay (2, " connects the mobile phone failure! ");
return；
}
}
}
If (! Ate_cmd_write_flag (m_lcdtype)) // send and revise the life that LCD indicates
Order is given mobile phone and is waited for the response of mobile phone
{
A failure of StateDisplay (2, " dirty bit! ");
return；
}
else
{
A success of StateDisplay (1, " dirty bit! ");
return；
}
BOOL ate_cmd_write_flag (int value) //value sign LCD type code
{
...
If (! SendCommandAte (value)) // send order by the UART mouth to mobile phone
{
return?FALSE；
}
Sleep (1200); // wait for for a moment, wait the mobile phone response
While (! ReceiveCommandAte (﹠amp; Ack)) // read the feedback of UART mouth
{
counter++；
if(counter＞READTIMES)
{
return?FALSE；
}
}
...
If (ACK_FAIL==ack) // judgement mobile phone response results
{
return?FALSE；
}
...
return?TRUE；
}
After above step was finished, mobile phone can correctly show the control of being correlated with to corresponding LCD, thereby had realized the compatibility of Different L CD display device.
When the inventive method made cell phone system hardware connect dissimilar LCD, cell phone software can cooperate PC side instrument to control the demonstration that adapts to dissimilar LCD flexibly.When same mobile phone hardware is changed Different L CD display device, need not to download again software, write corresponding flag bit by PC side instrument and can realize correct demonstration.Can be applicable to the frequent updating that factory produces flexible adaptation different display devices in the line production process.
Being preferred embodiment of the present invention only in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
