Hi Daniel,
The example es doing the trim, please look at the board.c file BOARD_tcxo32M_compensation_run. In this case, the example is not sending a temperature threshold and a delay.
Also, the function is calling the CLOCK_Xtal32M_Trim(XO_32M_OSC_CAP_Delta_x1000, &BOARD_Clock32MCapacitanceCharacteristics);
Regards,
Mario
