Problems solved by technology

The disadvantage of this method is that it lacks versatility, often only specific ICs can be configured, and generally only one or a series of ICs can be configured, which is difficult to fully meet the needs of system debugging

Embodiment Construction

[0046] The hardware connection mode of the device of the present invention is shown in Fig. 1, comprises PC, MCU (adopting STC516AD, compatible with INTEL8052), level conversion chip (adopting MAX3232) and I 2 C device. where I 2 C devices are connected to the MCU's two I 2 C interface. Since the P0 port of the MCU is an OC (Open Collector) output, it satisfies I 2 C's line AND requires, so I 2 The C interface is simulated by the P0 port of the MCU, among which P0.0 is the serial clock line of the analog channel 1, which is designated as SCL1, P0.1 is the serial data line of the analog channel 1, which is designated as SDA1, and P0.2 is the analog channel 2 The serial clock line of P0.3 is nominally SCL2, and the serial data line of P0.3 analog channel 2 is nominally SDA2. P0.0~P0.4 can be pulled up to 3.3V or 5V by jumper selection to be compatible with different logic level. in I 2 The circuit board where the C device is located does not need to 2 The C port is pulle...

Abstract

A system of carrying out debugging on I 2 C interface component through PC comprises a MCU for generating I 2 C time sequence, a serial interface communication interface for providing connection to PC serial interface and two I 2 C bus interfaces for proving connection of I 2 C but to I 2 C slave component. It is featured as connecting said debugging system to PC serial interface through said communication interface and to I2 C slave component through I 2 C interface virtualized by GPIO on MCU. Its debugging method is also disclosed.

Description

technical field [0001] The invention relates to the field of computer serial communication, in particular to a 2 A system and method for online debugging of a C device. Background technique [0002] Today, integrated circuits (ICs) are widely used in various electronic devices. These electronic devices construct various functional modules of the entire system based on integrated circuit blocks. Many ICs work together and cooperate with each other. Therefore, ICs need To communicate to coordinate, to communicate. To meet this need, various communication protocols have been continuously developed. Among them is a simple master-slave architecture communication method called I 2 C (Inter Integrated Circuit Bus), which uses three lines of SDA (Serial Data Line), SCL (Serial Clock Line) and GND (ground) to form serial transmission communication. I 2 The C bus interface has the advantages of fewer signal lines and convenient operation, and is usually used in occasions with sho...
