I am a mechanical engineer interested in Data Acquisition and Closed-Loop Control projects. As a beginner who wants to work with STM32 microcontrollers, I have a specific question about the STM32F7 DISCOVERY board: How can I perform Digital to Analog Conversion (DAC) using STM32F7 DISCOVERY board.
According to the user manual, the PA4 and PA5 pins of the STM32F746NG microcontroller are dedicated to High Speed USB and DCMI Camera connector. These pins are not directly available to the user (such as in Nucleo-F746ZG, in which the PA4 and PA5 pins are directly accessible through the morpho connectors). Do I need an extra board to perform DAC with STM32F7 DISCOVERY board?
What should I do to access the PA4 / PA5 pins for DAC operations that are essentially required in closed-loop control projects? Regards Mohsen
