Programming

Code examples for Fan 2 click, written for MikroElektronika hardware and compilers are

available on Libstock.

Codesnippet

The following code snippet shows 3 functions from the example that control the fan speed. The

first one initializes Fan 2 click to work automatically, depending on the temperature, while the

second and third one demonstrates manual control.

01 //sets fan to automatic control (default), and fills the look-up table

02 void Fan_2_Init()

03 {

04 FAN2_I2CdriverInit( I2CM1_Set_Slave_Address, 0, 0, I2CM1_Write_Bytes,

I2CM1_Read_Bytes);

05 FAN2_sendCommand(_FAN2_CONTROL_REGISTER_1, _FAN2_CMD1_DEFAULT);

06 FAN2_sendCommand(_FAN2_CONTROL_REGISTER_2, _FAN2_CMD2_DEFAULT);

07 FAN2_sendCommand(_FAN2_CONTROL_REGISTER_3, _FAN2_CMD3_DEFAULT |

_FAN2_CMD3_INSTANT_RAMP);

08 FAN2_setupLUT(LUTSettings);

09 }

11 //sets fan to manual control

12 void Fan_2_Manual()

13 {

14 FAN2_sendCommand(_FAN2_CONTROL_REGISTER_1, _FAN2_CMD1_DEFAULT);

15 FAN2_sendCommand(_FAN2_CONTROL_REGISTER_2, _FAN2_CMD2_DEFAULT |

_FAN2_CMD2_DIRECT_CONTROL);

16 FAN2_sendCommand(_FAN2_CONTROL_REGISTER_3, _FAN2_CMD3_DEFAULT |

_FAN2_CMD3_INSTANT_RAMP);

17 }

19 //turns fan on and off

20 void Fan_2_Task()

21 {

22 FAN2_sendCommand(_FAN2_DIRECT_CONTROL_REGISTER, _FAN2_DUTYCYCLE_100);

23 delay_ms (5000);

24 FAN2_sendCommand(_FAN2_DIRECT_CONTROL_REGISTER, _FAN2_DUTYCYCLE_0);

25 delay_ms (5000);

26 }
