Embodiment 1

[0021] Example 1. a kind of I 2 The wireless transmission system of C bus data is shown in Figure 1 and Figure 2. It includes a transmitter 1, a receiver 2 and a wireless path 3 between them. The transmitting end 1 and the receiving end 2 respectively have a built-in transmitting module and a receiving module. The transmitting module is connected to the CPU of the device at the transmitting end 1, and the receiving module is connected to the CPU of the device at the receiving end 2. Both transmitter 1 and receiver 2 are equipped with the following four registers: ①I 2 C_CC_SEND, a 255-byte write-only register 4 used to transfer data to the target unit; ②I 2 C_CC_RCV_LEN, read-only register 5 storing the length of the last received message; ③I 2 C_CC_RCV, the read-only register 6 that stores the last received information; ④I 2 C_CC_STATUS, read-only status register 7. The above four registers are all passed through the I 2 The C bus interface is connected with respectiv...

Abstract

A wireless transmission system of I2C bus data. The transmitting end and the receiving end are respectively inside set the transmitting module and receiving module. The transmitting module and the transmitting end equipment, the receiving module and the receiving end equipment, are respectively connected with their CPU. The transmitting end and the receiving end both equipped the following four registers: 1). I2C_CC_SEND the 255 bytes write-only register used for data transmission; 2). I2C_CC_RCV_LEN the read-only register used for received information length storage; 3). I2C_CC_RCV the read-only register used for received information storage; 4).I2C_CC_STATUS the read-only state register. The said four registers are connected with respective CPU through I2C bus interface. The transmitting and receiving modules are also connected with respective CPU through GPIO orifice by interrupt request lines. It realizes the wireless communications and the inter-switching of orders and control signals between the two CPU. Therefore it's more dependable and rapid, and won't be puzzled by data lines. Besides it can be widely applied in wireless home electrical appliances and equipments.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and more specifically relates to I 2 The design of wireless transmission system of C bus data. Background technique [0002] With the development of wireless transmission technology, more and more devices are interconnected wirelessly, and the devices that were originally connected to communicate with each other through data lines are separated by a certain distance or placed in different places (such as different rooms). The functions of traditional wireless transmission systems are relatively simple, only the transmission and reception of signals, and generally there is no problem of controlling and being controlled between two modules. [0003] However, with the improvement of wireless transmission system functions, devices need to pass I 2 The C bus communicates with each other to realize CPU control access and data exchange between two devices. If the I between them 2 C data is...
