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

Hello, IrDA has hardly been used for a long time, which is also marked in discontinued IrDA transceivers. However, since basically everything except the TIA and visual factors is included in the STM32 IrDA SIR ENDEC, it's possible to recreate IrDA with an IR LED plus driver transistor and an IR photRead more

RX and TX are switched to the IrDA function so that the LED driver and TIA can be connected directly.
