I want to add two leds to see when there is activity in the TX and RX pins of the microprocessor. It's a STM32 (3.3V port voltage). Attached you can find two pictures:
Line Driver.PNG is how my system would be wired.
RX TX. PNG is how I plan to add the LEDs to RX and TX port pins.

Do you think it works?
