Forum Post: RE: Keymatrix Switch Example

Hi KAROL, I  have checked the pin setup and its okay. When I call the open API  it directly jump on the callback function. The interrupt had enabled at the initialization. But if interrupt  is enabled after initialization, when  g_kint.p_api- enable(g_kint.p_ctrl) is called it jumps to the callback function. Is there any predefined callback function for the keymatrix ? Regards
