How to get data form param1 and param2

allejp commented 4 years ago

Hi, you can extract info in this way:

        uint8_t percentage = 0xFFFF & pEvent->param1;
        uint16_t voltage = 0xFFFF & pEvent->param2;

        PM_Charger_State_t cs = 0xFFFF & (pEvent->param1 >> 16);
        PM_Battery_State_t bs = 0xFFFF & (pEvent->param2 >> 16);

I noticed that the values are not updated quickly, the most updated value is obtained in this way:

        uint8_t percentage = 0;
        uint16_t voltage = PM_Voltage(&percent);
