[ARaul.2]

lcd working perfectly when i run code via arduino ide

and there are no errors also, can you please check out i2c files and code i have uploaded

[AScha.3]

ok, this time better information....

did you set adress correct ?

in : HAL_I2C_Master_Transmit(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, ...)

-> Target device address: The device 7 bits address value

 *     in datasheet must be shifted to the left before calling the interface

?

[ARaul.2]

this is set : #define SLAVE_ADDRESS_LCD 0x4E

address is 0x27 so it is perfect i guess
