    Hi Pratik,

    TFT LCD uses I2C communication protocol, you can learn the related configuration in the file GT911/GT911_Register.

    The reference code provided by TI about I2C communication can be seen in the attachments.

    You can refer to the code example to configure the MSP430 to realize the communication between them.

    I2C_Master_Transmit_Slave.txt

    I2C_Master_Read_Slave.txt

    Best Regards

    Hi Pratik,

    The basic code of MSP430FR5994 interfacing LCD is attached on the previous reply. I am sorry that the code attached is MSP430FR5739, and I have corrected it.

    The file "I2C_Master_Transmit_Slave.txt" shows the MSP430 work as Master in I2C protocol and transmit data to the slave, which is Capacitive Touch Controller (GT911).

    The file "I2C_Master_Read_Slave.txt" shows the MSP430 work as Master in I2C protocol and read data from the slave, which is Capacitive Touch Controller (GT911).

    More information about configuration of MSP430 I2C mode is attached: click on here (chapter 32). I think it will help you work with modification based on the reference code.

    As for slave, the files "GT911/GT911_Register.pdf" you attached, show the configuration of the slave mode of  Capacitive Touch Controller (GT911), please pay attention to the address and operate accordingly, shown in chapter 6.

    Best Regards

    Sal
