Hello,
After looking over all the documentation I could find (datasheet, source primer, etc.), I couldn’t easily find how I’m meant to connect IR LED (s) for Ir DA communication with an STM32WB55. The image I attached is a screenshot from the reference primer, which implies that there may be IrDA_OUT and, IN pins (I am interpreting this as being separate from the TX and RX pins). Am I supposed to add some intermediate IC for Ir DA, or can the STM32WB55 actually output signals for driving/ reading IR LEDs photodiodes?
I am aware of the actuality of the IR_OUT pins, but that’s its own separate thing. In the IR_OUT documentation, they use only timers (TIM16 & TIM17), not the US ART supplemental.
Thanks and Regards
