 Hi, I'm Nicolas Santini from ST Microelectronics, and during this lab session, I will demonstrate the two use cases that are supported by the ST ecosystem when developing with TouchDFX solution. The first use case, use case A, is when you prototype an application on an existing ST development kit. For example, a discovery kit or an evaluation kit. So these are pre-built devices based on an ST MCU, but with a specific display, specific external RAM, sometime external flash, etc. So they are good for prototyping to see what is possible with a given MCU and a selected set of external peripherals. The second use case will be on customer side when developing on a custom board, so based on an STM32 MCU, but with a specific display chosen by the customer as well as the external memory and all external peripherals.
