1. Data from 2 channels of STM32L476 Discovery kit will go through I2C to CY3274 kit and UART of STM32.
2. From CY3274 data will go to its UART and powerline and LCD.
Please use the same pins as used in CY3274 kit schematic (everything is available on the cypress website; examples of UART, I2C and schematics)
please use CubeIDE or Atollic for stm32 programming
