Embodiment Construction
[0057] Such as figure 1 with 2 Shown, in the processor with multi-channel I2C bus of the present invention, it mainly comprises processor main body, and the innovative point of the present invention is, the programmable logic device that is connected with processor main body is set, to the I2C bus line of processor main body To expand, the main body of the processor can have multiple I2C bus channels, and multiple different devices can be connected to each I2C bus, which can be a master device or a slave device. The main body of the processor uses the local bus to communicate with the programmable logic device through the address line, data line, read and write signal line and chip selection signal line, and completes the communication function with the main body of the processor by executing the control software inside the programmable logic device. At the same time, the complete I2C protocol is completed, and the function of the I2C bus controller is completed inside the pr...
