    Hello,

    You can use GIO API to turn on/off the LEDs connected to N2HET pins.

    1. initialize the GIO module: gioInit()

    2. Check the N2HET pin used for the LED: for example N2HET1[1]

    3. use GIO API to trn on this LED: gioSetPort(hetPORT1, gioGetPort(hetPORT1) ^ 0x00000002);

    The HALCOGen N2HET example code may use this N2HET pin of rother purpose (PWM, capture, edge detection, etc), please don't run hetInit().
