What is the minimum program content required for the evaluation board (STEVAL-ISA164V1) to communicate with ST_SMED_Configurator? Supplement: I am using STNRG388.

[HKOBA.1]

From the drawing of DocID28549, PIN22 of the evaluation board (STEVAL-ISA164V1) is described as UART_Tx and PIN23 is described as UART_Rx, but if you search for UART in the attached source file, PIN17 and PIN18 will be searched.

Which part of the attached source file makes it possible to communicate with ST_SMED_Configurator?

I hope you'll tell me.
