Embodiment Construction

[0040] Taking TV as an example, a best way of realizing the present invention will be introduced below. As shown in the attached figure, this dedicated I 2 The C interface contains a total of 5 signal terminals, which are:

[0041] ① SCL: I 2 C bus clock line, connected with the SCL inside the TV,

[0042] ②SDA:I 2 C bus data line, connected with SDA inside the TV,

[0043] ③V CC : External I 2 C power supply input (generally +5V, you can input the corresponding voltage if you have special requirements), and the E inside the TV 2 PROM power supply terminal connected,

[0044] ④GND: ground, and E inside the TV 2 PROM power ground and I 2 The ground wire of C is connected,

[0045] ⑤ID: Operation function selection input terminal, connected with the reset (RESET) pin of the MCU inside the TV. This pin has two states, which vary with the function.

[0046] When copying user data needs to be realized, in order to prevent I 2 C bus conflict occurs, the I 2 The signal ...

Abstract

The invention relates to a method for refreshing the data of electric product, which uses special I2C bus plug to lead internal signal outside the product, and uses relative cable; and uses said plug to connect the I2C bus with external memory eraser; then uses external eraser to process the data of memory. The invention has low cost, and simple operation, to improve the working efficiency.

Description

technical field [0001] The present invention involves the use of I 2 C bus protocol for control and data transmission of various electronic products, especially the radio and television receiver products. Background technique [0002] I 2 The C bus is a convenient way to transmit data between integrated circuits. Its biggest advantage is that it only uses two lines for transmission, which brings convenience to circuit board wiring. Because of this, it is widely used in various in electronic products. [0003] However, such products will encounter subsequent reading and writing upgrade problems during the production process and after-sales service. We know that the product always needs to be debugged during the production process. Since the manufacturer has special read-write equipment, data update is not a problem, but after sales, there will be the possibility of software upgrades. With the rapid development of science and technology, many devices are for Data needs to ...
