Custom pinout

In case these pins are not good for you, you can use TM_I2C_PinsPack_Custom in TM_I2C_Init() function and callback function will be called, where you can initialize your custom pinout for your I2C peripheral

Possible changes in your defines.h file: Change x to your I2C used, 1-3

//By default library support only 7bit long address
#define TM_I2Cx_ACKNOWLEDGED_ADDRESS   I2C_AcknowledgedAddress_7bit
//Library supports I2C mode
#define TM_I2Cx_MODE                   I2C_Mode_I2C
//Own address, if slave mode
#define TM_I2Cx_OWN_ADDRESS            0x00
//By default, disable ack
#define TM_I2Cx_ACK                    I2C_Ack_Disable
//Duty cycle 2, 50%
#define TM_I2Cx_DUTY_CYCLE             I2C_DutyCycle_2
