Set Target Order & Thresholds in 53L5A1 BSP for VL53L5A1 Multi-Sensor Ranging?

[moj]

In the 53L5A1 Board Support Package (BSP) for the VL53L5A1 Multi-Sensor Ranging module, setting the target order (e.g., VL53L5CX_TARGET_ORDER_STRONGEST or VL53L5CX_TARGET_ORDER_CLOSEST) doesn't seem to be directly exposed through the existing BSP functions.

The vl53l5cx_set_target_order() function in the vl53l5cx_api.h (from the VL53L5CX API) uses a different configuration structure (VL53L5CX_Configuration) compared to the structure used in the 53L5A1 BSP.

Is there any guidance, documentation, or example code available on how to create a wrapper function to bridge these APIs and control the target order and detection thresholds for each individual ToF sensor within the multi-sensor ranging module?

You don't see a:

uint8_t vl53l5cx_set_target_order(
		VL53L5CX_Configuration		*p_dev,
		uint8_t				target_order)

function in the vl53L5cx_api.c

Should be there. 

But if you are using the XCode_ToF, the functions get abstracted. 

That code tries to make a uniform interface even though the chips really are kind of different. 

And that leaves some stuff out. 

Your challenge is to figure out *p_dev is. 

With that you can call the functions in the API directly instead of going through the BSP.

I found a typo in my code Platform_Init of the Dev structure - below code seems to work.

VL53L5CX_Configuration Dev;


void VL53L5CX_Platform_Init() {
    Dev.platform.address = 0x52;
    Dev.platform.Read = VL53L5A1_I2C_ReadReg ;
    Dev.platform.Write = VL53L5A1_I2C_WriteReg;
    Dev.platform.GetTick = VL53L5A1_GetTick;
}


uint16_t VL53L5A1_GetI2CAddress(uint32_t device) {

	switch (device) {
        case 0:
            return 0x54;
        case 1:
            return 0x56;
        case 2:
            return 0x58;
        default:
            return 0x00;
    }
}


int32_t VL53L5A1_RANGING_SENSOR_SetTargetOrder(uint32_t device, uint8_t target_order){
    uint8_t status;

    Dev.platform.address = VL53L5A1_GetI2CAddress(device);

    // Set the target order using the VL53L5CX API
    status = vl53l5cx_set_target_order(&Dev, target_order);
    if (status != 0) {
        return BSP_ERROR_COMPONENT_FAILURE;
    }

    return BSP_ERROR_NONE;
}
