Q:How do I connect the DE and RE# pins on STM32F103VBSA%2B.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF-ALT.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF-ASA%2B for automatic direction control?
A:In typical half-duplex microcontroller circuits, connect DE (Driver Enable, Active High) and RE# (Receiver Enable, Active Low) together to a single MCU GPIO pin. Driving the pin HIGH enables transmission, while pulling it LOW sets the device into receive mode.
Q:What termination resistor is required on the RS-485 bus line for STM32F103VBSA%2B.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF-ALT.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF.PDF-ASA%2B?
A:A 120-ohm termination resistor should be placed across the A and B differential lines at the two physical ends of the cable to match the characteristic impedance of standard twisted-pair cables and eliminate signal reflections.
