I use a STM32f4vgt6 and I configured the PWM to control a DC motor. The problem is that when I measure the output PWM tention I notice that it does not exceed the 3V. When I connect the VDD pin to 5V, the problem is solved and the max output be came 5V ! Who can explain me this phenomenon ? thank you in advence
