具觸控晶片的電腦裝置及該觸控晶片的更新方法 Computer device with touch chip and method for updating the same

本領域是關於一種觸控晶片，特別是關於一種觸控晶片的更新方法。 The field relates to a touch wafer, and more particularly to a method for updating a touch wafer.

習知觸控裝置的觸控晶片需要有快閃記憶體(flash memory)來儲存觸控韌體，這是為了當觸控裝置的環境特性改變時，能夠更新觸控韌體。 The touch wafer of the conventional touch device needs to have a flash memory for storing the touch firmware, so that the touch firmware can be updated when the environmental characteristics of the touch device are changed.

觸控裝置，例如觸控板，廣泛的應用在筆記型電腦。觸控裝置的觸控晶片存在著更新韌體的需求。目前常見的觸控韌體的更新方法有二種，第一種是軟體燒錄(In-Application Programming；IAP)，第二種是外部機台燒錄(In-System Programmable；ISP)。但是不論那種更新方法，觸控晶片都必需有快閃記憶體，因此現有的觸控晶片需要採用高成本的快閃記憶體製程。而且要對快閃記憶體進行寫入必須經過燒錄的步驟，過程複雜且速度較慢。此外，因應不同的環境特性，例如不同的筆記型電腦具有不同的覆蓋觸控裝置的上蓋或固定觸控裝置的鐵件，需要製備多種具有不同觸控韌體的觸控晶片，這也增加物料管理的難度。 Touch devices, such as touchpads, are widely used in notebook computers. The touch wafer of the touch device has a need to update the firmware. At present, there are two common methods for updating touch firmware. The first one is In-Application Programming (IAP), and the second is In-System Programmable (ISP). However, regardless of the update method, the touch wafer must have flash memory, so the existing touch chip requires a high-cost flash memory system. Moreover, the process of writing to the flash memory must be subjected to a burning process, which is complicated and slow. In addition, depending on different environmental characteristics, for example, different notebook computers having different cover covers of the touch device or iron members for fixing the touch device, it is necessary to prepare a plurality of touch wafers having different touch firmware, which also increases materials. The difficulty of management.

圖1是美國專利公開號US 2007/0260790的架構，其提出一種更新嵌入式控制器26的韌體的方法。嵌入式控制器(Embedded Controller；EC)26連接基本輸入輸出系統(Basic Input Output System；BIOS)28，嵌入式 控制器26具有快閃記憶體，且用以管理多個周邊裝置，例如觸控板及鍵盤。在電腦或南橋晶片30未啟動前，嵌入式控制器26切換成主裝置(host)模式並且從BIOS28下載韌體並將韌體燒錄至快閃記憶體中，韌體更新後，嵌入式控制器28將切換回副裝置模式。但是，這種更新韌體的方法，仍然需要快閃記憶體以及透過燒錄方式將韌體寫入快閃記憶體，故仍具有高成本及更新速度較慢的問題。另一方面，嵌入式控制器26和BIOS28都是屬於主機板的元件，該專利僅提供主機板上的嵌入式控制器26的更新方法，並沒有提供嵌入式控制器26管理的周邊裝置(例如觸控板或鍵盤)的更新方法。 1 is an architecture of US Patent Publication No. US 2007/0260790, which proposes a method of updating the firmware of the embedded controller 26. Embedded Controller (EC) 26 is connected to the Basic Input Output System (BIOS) 28, embedded The controller 26 has flash memory and is used to manage a plurality of peripheral devices such as a touchpad and a keyboard. Before the computer or south bridge chip 30 is not started, the embedded controller 26 switches to the host mode and downloads the firmware from the BIOS 28 and burns the firmware into the flash memory. After the firmware is updated, the embedded control is performed. The device 28 will switch back to the secondary device mode. However, this method of updating the firmware still requires flash memory and writing the firmware to the flash memory through the burning method, so that the problem of high cost and slow update speed is still high. On the other hand, both the embedded controller 26 and the BIOS 28 are components belonging to the motherboard. This patent only provides an update method for the embedded controller 26 on the motherboard, and does not provide peripheral devices managed by the embedded controller 26 (for example Update method for touchpad or keyboard).

The touch chip 10 in the touch device 6 includes a random access memory (RAM) 12 and a read-only memory ( The Read Only Memory (ROM) 14 is configured to store an algorithm, a preset second touch parameter, and a preset second touch program. The first touch parameter may be, for example, a touch sensitivity parameter, a cursor speed parameter, or a noise filter parameter, or other parameters for environmental characteristics; the first touch program is configured to provide a first touch function, such as anti-palm The function and the multi-finger gesture function; the second touch parameter includes a common standard parameter; and the second touch program provides a second operation function, such as a cursor operation function. Before the first touch parameter and the first touch program are loaded into the touch wafer 10, the touch device 6 can perform basic operations, such as a cursor, according to the second touch parameter and the second touch program in the ROM 14. control. During the power on process of the computer device 2, the touch firmware update will be performed after the BIOS 4 is started, and the BIOS 4 will send the write command Cw, the first touch parameter and the first touch program via the south bridge. The chip 16 and the transmission interface 18 are transmitted to the touch wafer 10 of the touch device 6. After receiving the write command Cw, the touch wafer 10 stores the first touch parameter and the first touch program to the RAM 12, and then touches The control chip 10 can operate using the first touch parameters and the first touch program in the RAM 12.

BIOS 4可以透過不同的途徑將第一觸控參數及第一觸控程序傳送到觸控晶片10。圖3係本發明的第二實施例，其中電腦裝置2包含BIOS 4、觸控裝置6、嵌入式控制器20連接BIOS 4以及傳輸介面18連接觸控裝置6。在不同的實施例中，嵌入式控制器20可以直接或透過其他元件連接傳輸介面18。同樣的，圖3中的BIOS 4中的記憶體8儲存用以更新的第一觸控參數及第一觸控程序，觸控晶片10的ROM 14儲存一演算法、一預設的第二觸 控參數及一預設的第二觸控程序。在第一觸控參數及第一觸控程序載入觸控晶片10前，觸控裝置6係根據ROM 14中的第二觸控參數及第二觸控程序能執行基本的操作。在電腦裝置2開機的過程中，在BIOS 4啟動後，BIOS 4將進行觸控韌體更新，此時BIOS 4送出寫入命令Cw、第一觸控參數及第一觸控程序經嵌入式控制器20及傳輸介面18傳送給觸控裝置6的觸控晶片10，觸控晶片10在收到寫入命令Cw後將接收到的第一觸控參數及第一觸控程序寫入RAM 12。 The BIOS 4 can transmit the first touch parameter and the first touch program to the touch wafer 10 through different channels. 3 is a second embodiment of the present invention, wherein the computer device 2 includes a BIOS 4, a touch device 6, an embedded controller 20 connected to the BIOS 4, and a transmission interface 18 connected to the touch device 6. In various embodiments, embedded controller 20 can connect to transmission interface 18 directly or through other components. Similarly, the memory 8 in the BIOS 4 of FIG. 3 stores the first touch parameter and the first touch program for updating, and the ROM 14 of the touch wafer 10 stores an algorithm and a preset second touch. Control parameters and a preset second touch program. Before the first touch parameter and the first touch program are loaded into the touch wafer 10, the touch device 6 can perform basic operations according to the second touch parameter and the second touch program in the ROM 14. During the startup of the computer device 2, after the BIOS 4 is started, the BIOS 4 will perform the touch firmware update, and the BIOS 4 sends the write command Cw, the first touch parameter and the first touch program through the embedded control. The sensor 20 and the transmission interface 18 are transmitted to the touch wafer 10 of the touch device 6. The touch wafer 10 writes the received first touch parameter and the first touch program to the RAM 12 after receiving the write command Cw.

在圖2及圖3的實施例中，由於電腦裝置2從開機到啟動BIOS 4的時間很短，通常在使用觸控裝置6之前就會完成觸控韌體的更新，因此在其他的實施例中，ROM 14也可以不儲存第二觸控參數及第二觸控程序。 In the embodiment of FIG. 2 and FIG. 3, since the time period from the startup of the computer device 2 to the startup of the BIOS 4 is very short, the update of the touch firmware is usually completed before the touch device 6 is used, and thus in other embodiments. The ROM 14 may not store the second touch parameter and the second touch program.

圖4係本發明的第三實施例，其中電腦裝置2包含儲存裝置22、觸控裝置6以及傳輸介面18連接觸控裝置6。在不同的實施例中，儲存裝置22可以直接或透過其他元件連接傳輸介面18。儲存裝置22儲存電腦裝置2所使用的多個驅動程式以及第一觸控參數及第一觸控程序，該多個驅動程式中包含一個用以執行觸控韌體更新的驅動程式，觸控裝置6的觸控晶片10包含RAM 12以及ROM 14，ROM 14用以儲存演算法、預設的第二觸控參數及第二觸控程序。在第一觸控參數及第一觸控程序載入觸控晶片10前，觸控裝置6係根據ROM 14中的第二觸控參數及第二觸控程序執行基本的操作。在電腦裝置2開機過程中，對應觸控韌體更新的驅動程式被執行，儲存裝置22送出寫入命令Cw、第一觸控參數及第一觸控程序經傳輸介面18傳送給觸控裝置6的觸控晶片10，觸控晶片10根據寫入命令Cw將第一觸控參數及第一觸控程序儲存至RAM 12，之後觸控晶片10使用RAM 12中的第一觸控 參數及第一觸控程序進行運作。 4 is a third embodiment of the present invention, wherein the computer device 2 includes a storage device 22, a touch device 6, and a transmission interface 18 connected to the touch device 6. In various embodiments, storage device 22 can connect transmission interface 18 directly or through other components. The storage device 22 stores a plurality of drivers for the computer device 2, and a first touch parameter and a first touch program. The plurality of drivers include a driver for performing touch firmware update, and the touch device The touch wafer 10 of 6 includes a RAM 12 and a ROM 14, and the ROM 14 is configured to store an algorithm, a preset second touch parameter, and a second touch program. Before the first touch parameter and the first touch program are loaded into the touch wafer 10, the touch device 6 performs basic operations according to the second touch parameter and the second touch program in the ROM 14. During the startup of the computer device 2, the driver corresponding to the touch firmware update is executed, and the storage device 22 sends the write command Cw, the first touch parameter and the first touch program to the touch device via the transmission interface 18. The touch wafer 10, the touch wafer 10 stores the first touch parameter and the first touch program to the RAM 12 according to the write command Cw, and then the touch wafer 10 uses the first touch in the RAM 12. The parameters and the first touch program operate.

在不同的實施例中，新的演算法也可以儲存在BIOS 4中的記憶體8或儲存裝置22，透過上述各實施例的方式，儲存到觸控晶片10的RAM12中，供觸控晶片10使用。 In a different embodiment, the new algorithm can also be stored in the memory 8 or the storage device 22 in the BIOS 4, and stored in the RAM 12 of the touch wafer 10 for the touch wafer 10 in the manner of the above embodiments. use.

在圖2、圖3及圖4中，實現本發明更新方法的觸控晶片10只需要RAM 12及ROM 14，並不需要快閃記憶體，因此觸控晶片10可以用低成本的邏輯製程來製作，有助於降低觸控晶片10的成本。對於BIOS 4的記憶體8的容量或者儲存裝置22的容量來說，第一觸控參數及第一觸控程序是非常小的，因此也不需要額外增加記憶體8及儲存裝置22的容量，不會增加成本。再者，本發明將第一觸控參數及第一觸控程序寫入RAM 12並不需要進行燒錄，因此本發明的更新觸控晶片所需韌體的方法具有較快的更新速度。另一方面，本發明只有將觸控晶片執行基本操作所需的韌體預先儲存在觸控晶片10的ROM 14，其他因應不同需求的第一觸控參數及第一觸控程序則藉由上述的方式來提供給觸控晶片10，因此同一顆觸控晶片10可以適用不同的電腦裝置，這可以使物料管理變容易。 In FIG. 2, FIG. 3 and FIG. 4, the touch wafer 10 implementing the updating method of the present invention only needs the RAM 12 and the ROM 14, and does not require flash memory. Therefore, the touch wafer 10 can be processed by a low-cost logic process. The fabrication helps to reduce the cost of the touch wafer 10. For the capacity of the memory 8 of the BIOS 4 or the capacity of the storage device 22, the first touch parameter and the first touch program are very small, so there is no need to additionally increase the capacity of the memory 8 and the storage device 22. Will not increase costs. Moreover, the method for writing the first touch parameter and the first touch program into the RAM 12 does not need to be burned. Therefore, the method for updating the firmware required for the touch wafer of the present invention has a faster update speed. On the other hand, in the present invention, only the firmware required for performing the basic operation of the touch wafer is pre-stored in the ROM 14 of the touch wafer 10, and the first touch parameters and the first touch program corresponding to different requirements are The method is provided to the touch wafer 10, so that the same touch wafer 10 can be applied to different computer devices, which can make material management easier.

在一實施例中，在載入第一觸控參數及第一觸控程序之後，觸控晶片10只根據第一觸控參數及第一觸控程序進行操作，而不使用預先儲存在觸控晶片10的ROM14的第二觸控參數及第二觸控程序。在其他實施例中，在載入第一觸控參數及第一觸控程序之後，觸控晶片10仍然會使用第一觸控參數及第一觸控程序的一部份或全部。意即，根據本發明，第一觸控參數及第一觸控程序可以是用來取代預先儲存在觸控晶片10的ROM 14的第二觸控參數及第二觸控程序，也可以是為觸控晶片提供基本操作之 外的其他更多功能。 In one embodiment, after loading the first touch parameter and the first touch program, the touch wafer 10 operates only according to the first touch parameter and the first touch program, without using pre-stored touch The second touch parameter of the ROM 14 of the wafer 10 and the second touch program. In other embodiments, after loading the first touch parameter and the first touch program, the touch wafer 10 still uses the first touch parameter and some or all of the first touch program. That is, according to the present invention, the first touch parameter and the first touch program may be used to replace the second touch parameter and the second touch program stored in advance in the ROM 14 of the touch wafer 10, or may be Touch chip provides basic operation More other features.
