WebJul 12, 2024 · 4. USB to Serial adapters with a DE9 connector use RS-232 Voltage levels, where logical 0 is a positive voltage between 3 and 15 volts, and logical 1 is a negative voltage between -3 and -15 volts. STM32 Microcontrollers use TTL-like signaling, where logical 0 is between approximately 0 and 0.7 volts, logical 1 is between 2 and 5 volts.

WebJun 5, 2024 · It is a brushless DC motor with an interface similar to a stepper motor. The motor rotates for a defined distance based on the number of pulses it receives from the PWM. The speed is determined by the pulse frequency of the PWM, like a stepper motor. To control this motor I am using a microcontroller STM32F407ZET6. common baby mother
