WebbThis 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 WebbI 2 C is a fairly robust protocol, and can be used with short runs of wire (2-3m). For long runs, or systems with lots of devices, smaller resistors are better. Most I 2 C devices offered in the SparkFun catalog usually include pull-up resistors for the SCL and SDA pins.
