And if the master still wishes to communicate on the bus it can generate another slave address along with repeated start condition without generating first stop condition. I2C Module generates interrupt on the 9th clock cycle. All data transfers must be preceded by a Start condition. To use MikroC Pro for I2C communication, we just need to understand the working of each function associated with this library. Posted on May 28, 2014 at 14:40 . The high or low state of the data line can only be changed when the clock signal on the SCL line is LOW. The main difference should be that some of the operations are of no use (for example : enforcing the state of pins is not required, as in I2C mode only the TRIS needs to be changed). It selects SMBus S. We can configure it in Master or Slave mode like this: In Master mode, this bit is reserved. After that Programer can load the 8-bit data to the SSPBUF register that user wants to transmit to the slave device ( through SDA line). The code in this sample does several things: Initializes the I2C bus and the port expander. #include "Driver_I2C.h" #define EEPROM_I2C_ADDR 0x51 /* EEPROM I2C address */ /* I2C driver instance */ extern ARM_DRIVER_I2C Driver_I2C0; static ARM_DRIVER_I2C *I2Cdrv = &Driver_I2C0; static volatile uint32_t I2C_Event; /* I2C … Usage guide Initializing the sensor.
