Getting Charger State how to solve it? generate chatgpt solution for beginner

To handle API_EVENT_ID_POWER_INFO and extract the charger state in the GPRS C SDK, you need to interpret the parameters param1 and param2 correctly. These parameters are bit-packed to provide multiple pieces of information. Here’s how you can extract the charger state from param1.

Breakdown of Parameters

• param1: Contains the charger state and the charge level.
• Charger State: PM_Charger_State_t (upper 16 bits)
• Charge Level: Charge level in percentage (lower 16 bits)
• param2: Contains the battery state and the battery voltage.
• Battery State: PM_Battery_State_t (upper 16 bits)
• Battery Voltage: Battery voltage in millivolts (lower 16 bits)

Here is an example of how you can extract the charger state from param1:

#include <stdio.h>
#include "api_event.h"
// Example enum for PM_Charger_State_t
typedef enum {
    CHARGER_STATE_DISCONNECTED = 0,
    CHARGER_STATE_CONNECTED,
    CHARGER_STATE_CHARGING,
    CHARGER_STATE_FULL,
    // Add other states as per your SDK documentation
} PM_Charger_State_t;
// Event handler function
void EventDispatch(API_Event_t* pEvent) {
    if (pEvent->id == API_EVENT_ID_POWER_INFO) {
        // Extract charger state and charge level from param1
        uint16_t chargerState = (pEvent->param1 >> 16) & 0xFFFF;
        uint16_t chargeLevel = pEvent->param1 & 0xFFFF;
      // Extract battery state and battery voltage from param2
        uint16_t batteryState = (pEvent->param2 >> 16) & 0xFFFF;
        uint16_t batteryVoltage = pEvent->param2 & 0xFFFF;
        // Print extracted values
        printf("Charger State: %d\n", chargerState);
        printf("Charge Level: %d%%\n", chargeLevel);
        printf("Battery State: %d\n", batteryState);
        printf("Battery Voltage: %dmV\n", batteryVoltage);
        // Process charger state
        switch(chargerState) {
            case CHARGER_STATE_DISCONNECTED:
                printf("Charger is disconnected.\n");
                break;
            case CHARGER_STATE_CONNECTED:
                printf("Charger is connected.\n");
                break;
            case CHARGER_STATE_CHARGING:
                printf("Charging in progress.\n");
                break;
            case CHARGER_STATE_FULL:
                printf("Battery is fully charged.\n");
                break;
            default:
                printf("Unknown charger state.\n");
                break;
        }
    } else {
        printf("Other Event Received\n");
    }
}
int main() {
    // Initialize the system and register the event handler
    API_Event_Register(EventDispatch);
    // Main loop
    while (1) {
        // Perform other tasks
    }
    return 0;
}

Explanation

Extract Charger State: uint16_t chargerState = (pEvent->param1 >> 16) & 0xFFFF;

• Shifts param1 right by 16 bits to get the upper 16 bits.
• Masks with 0xFFFF to ensure we get the correct value.

Extract Charge Level: uint16_t chargeLevel = pEvent->param1 & 0xFFFF;

• Masks param1 with 0xFFFF to get the lower 16 bits.

Extract Battery State: uint16_t batteryState = (pEvent->param2 >> 16) & 0xFFFF;

• Similar process as extracting charger state but from param2.

Extract Battery Voltage: uint16_t batteryVoltage = pEvent->param2 & 0xFFFF;

• Similar process as extracting charge level but from param2.

By correctly interpreting these bit-packed parameters, you can extract and handle the necessary power information in your application. Make sure to adapt the PM_Charger_State_t enum and the handling logic as per your SDK documentation.
