Problems solved by technology

[0003] The controller used for the capacitive touch device can choose several storage elements according to the characteristics of the internal read-only memory of the microprocessor, such as mask read-only memory (MaskROM), one-time programmable read-only memory (OTPROM) ) and flash memory (FlashMemory). At present, a microprocessor with flash memory is usually used as a controller. The most direct advantage is that the firmware stored in the flash memory can be erased and rewritten, which is conducive to the development of different touch device applications or convenient Reset the built-in calculation program; relatively, the flash memory is more expensive than the other two processes because of the many and complicated mask processes

Embodiment Construction

[0049] The present invention proposes a capacitive touch device using a controller with a non-rewritable ROM to meet the requirements of low cost and flexible application.

[0050] See first figure 1 As shown, the capacitive touch device 10 of the present invention includes a touch panel 11 and a controller 12 . The touch panel 11 includes a plurality of sensing units 111a, 111b, usually a plurality of first axis sensing units 111a and second axis sensing units 111b arranged in a staggered manner. The controller 12 is electrically connected to the plurality of first axis sensing units 111 a and second axis sensing units 111 b of the touch panel 11 .

[0051] Please refer to figure 2 As shown, the controller 12 includes a processing unit 121, a non-rewritable read-only memory 122, a memory unit 123 and a peripheral interface circuit 124; wherein the processing unit 121 is electrically connected to the non-rewritable read-only memory 122, The memory unit 123 and the peripher...

Abstract

The invention relates to a capacitive-type touch control electronic device, a touch control device, and a mode selection method therefor. The device comprises a touch control panel and a controller. The controller comprises a non-rewrite type read-only memory and a storage unit, wherein the non-rewrite type read-only memory stores a coordinate recognition program, and the storage unit stores a temporary storage setting file which comprises an operation mode selection parameter. Therefore, a parameter is selected according to an operation mode of the temporary storage setting file when the controller is started, and a first operation mode or a second operation mode is determined to be carried out. When the first operation mode is determined to be carried out, a touch control panel is scanned according to the temporary storage setting file, and the scanning data is directly outputted, and is analyzed externally, thereby avoiding the discarding and replacing of the controller of the non-rewrite type read-only memory storing the coordinate recognition program.

Description

technical field [0001] The present invention relates to a capacitive touch device, in particular to a capacitive touch device capable of selecting a data calculation mode. Background technique [0002] At present, the capacitive touch device mainly includes a touch panel and a controller, the controller is electrically connected to the touch panel to drive and receive the sensing signal of the touch panel, so the controller will cooperate with it according to the The internal firmware (Firmware) is designed according to the specifications and touch requirements of the touch panel, so that the touch panel can be used according to different touch function requirements. [0003] The controller used for the capacitive touch device can choose several storage elements according to the characteristics of the internal read-only memory of the microprocessor, such as mask read-only memory (MaskROM), one-time programmable read-only memory (OTPROM) ) and flash memory (FlashMemory). At ...
