We are developing the TouchGFX project in STM32F746BGT6 and using resistive Touchscreen
We have created the project using ST CUBEMX for discovery board .the same project code has been used for our customized PCB.
For this we need to interface the STMPE811 touch controller for getting touch information from resistive touch screen.We have used STMPE811 Driver code and I2C protocol is used in this driver code
While trying to connect with Touch controller with address(0x82) it will return HAL error.
I have checked with Oscilloscope SCL and SDA pin ,Clock was generated at 92 Khz
please help me in this issue
speed 100KHz
Standard mode
I2C clock source frequency 50Mhz
