资料介绍

1 Introduction This application note implements an I2C driver on MQX based on interrupt and blocking mechanism, which masked the details of the I2C module operations and simplifies the application code to a great extent. It covers both the master and slave modes. The code is validated on the K60N512-TWR board. 2 How the driver is designed This driver is fully driven by interrupt. Following is the operation of driver in master and slave modes. • Master mode: When it is working as a master and sending data, the application task passes the address and length of buffer to driver and after that, it is blocked. After the driver finishes transmitting the data in the buffer, it resumes the application task. To reduce memory consumption, the driver does not make its own buffer and copy the data from application to it. The driver uses the buffer at application layer directly. In the same way, when the master is receiving, it passes theaddress and length of buffer to the driver, and then, it is pended by the driver until driver finishes the reading operation. See Figure 1. • Slave mode: There are some differences when it is working as a slave. A slave is working in a passive way, not as a master does. So, when it is sending data, it keeps blocked until the master reads it. When it is reading, it will keep blocked until the master sends data to it. See Figure 1.
