Embodiment Construction

[0032] Specific embodiments of the present invention will be described more fully below in conjunction with the accompanying drawings.

[0033] The present invention can repeat the circuit device and realization method of online programming, such as figure 1 Shown, its system comprises a computer, runs a control program on this computer; Set the core digital circuit control chip of TV set simultaneously as a chip with online programming update ISP (IN SYSTEM PROGRAM) function, as EnME0509 chip, The data transmission pins RXD and TXD of the chip are respectively connected to the casing of the TV set as a predetermined interface. In a preferred embodiment of the present invention, the interface is set as a VGA interface of the TV set. Because the VGA interface of television set is used less, therefore can be connected on the idle pin of VGA, certainly in fact the present invention can be provided with a brand-new interface fully.

[0034] Realize the inventive method, must make...

Abstract

The invention is used in TV circuit board. The apparatus thereof comprises: an interface board circuit and a TV control chip. Said interface board circuit is used for connecting 9-pin serial port of a computer to the I / O pins of TV control chip, and comprises a level conversion circuit used for converting the level of 9-pin serial port to the level desired by the TV control chip. On said computer there is an on-line updating programming program installed for updating the TV control chip on-line.

Description

technical field [0001] The present invention relates to a TV program update circuit device and method, in particular to a device and method for implementing repeatable online programming for programming and debugging of TV software. The TV realizes online programming and debugging. Background technique [0002] With the advancement of technology, the realization of more and more TV functions and the adjustment of picture quality rely on the cooperation of software and hardware. The control chip is disassembled, and the software is updated through the programmer. The setting method of the prior art is not convenient for the designer to debug the software and modify the parameters at any time, and the repeated loading and unloading of the IC is easy to cause damage to the IC, thereby increasing the design cost and prolonging the design cycle; the use of the existing debugging tools is complex and The cost is expensive, which is not conducive to the rapid and smooth progress ...
