Application example

This application example demonstrates how to use the peripheral interconnect matrix on

STM32F7 Series microcontrollers, how to set up ADC3 to start a single conversion at each

TIM2 time overflow. At each end of conversion the DMA transfers the converted data from

the ADC to the memory.

This application uses the STM32F7xx HAL API.
