Embodiment 1

[0037] Example 1, such as figure 1 and figure 2 Shown: a software reset consumables system, including a printer and a software reset consumables chip. This kind of software reset consumable chip can only have four contacts on the hardware, which are a GND contact, which is the ground contact, a VCC contact, which is the power line contact, and a CLK contact, which is the clock line. Contact, a DAT contact, that is, a data line contact.

[0038] This software reset consumable chip contains a communication module, and the chip communicates with the printer by means of the communication module. The communication module can adopt the I2C communication protocol. When the communication between the printer and the chip stops, and the chip still has no feedback after the preset time, the printer generates a reset signal and sends it to the communication module, which enters step 1, namely the step of generating a reset signal.

[0039] Then enter step 2, that is, the step of gene...

Embodiment 2

[0044] The main difference between the second embodiment and the first embodiment is the way in which the reset flag is generated. In the first embodiment, the reset flag is generated by the specific timing of the trigger module, while in the second embodiment, the implementation of command trigger is adopted.

[0045] Specifically, the chip includes a control unit, that is, an MCU. The MCU is connected with the communication module and the hardware reset module. The MCU can receive the reset signal from the printer sent by the communication module.

[0046] The data sent by the printer can be a string of character data, such as 0x00 0x94 0x00 0x01 0x02 0x030x04 0x98 0x45+XOR.

[0047] Among them, 0x00 0x94 represents the command word, that is, the first two bytes of each communication are 0x00 0x94. And 0x00 0x01 0x02 0x03 0x04 0x98 0x45 can be used as comparison data, XOR is the exclusive OR of all the previous data for verification. After the MCU receives it, it judges ...

Abstract

The invention relates to the field of printing, and specifically relates to a software reset consumable chip and system, and a use method thereof. The invention is implemented by the following technical scheme: the software reset consumable chip comprises a control unit comprising a communication module for receiving a reset signal, wherein the communication module is connected with the control unit; the software reset consumable chip further comprises a hardware reset module; the communication module sends the reset signal to a trigger module or the control unit, and the trigger module or the control unit can trigger a reset mark to the hardware reset module; and the hardware reset module starts program reset according to the reset mark. The invention aims at providing the software reset consumable chip and system, and the use method thereof. The reset signal is responded depending on the hardware reset module arranged in the chip to perform software reset on the chip without adding additional trigger space of pins or affecting the function continuity of the chip.

Description

technical field [0001] The invention belongs to the field of printing, and in particular relates to a software reset consumable chip, a system and a use method thereof. Background technique [0002] With the popularization of office automation, printing equipment has become an indispensable equipment in office activities. During the printing process, printer hosts and consumables such as ink cartridges are needed. At present, consumables generally use chips as the medium of information and consumption of consumables, and the software data and configuration data required for chip operation are often stored on the chip. [0003] During the operation of the chip, due to various reasons, the internal program may run away or enter an infinite loop. At this time, the chip needs to be chipped for the normal use of the chip. In the prior art, there are usually two processing methods for chip reset. The first method is to provide a CE pin on the chip as a reset signal, but this pro...
