While implementing the middleware for vl53l0x I am facing the following problem. Can you please let me know what mistake am I making
“please see the commands in bold�?
tofDev->I2cDevAddr = VL53L0X_I2C_ADDR //0x52;
tofDev->comms_type = I2C ;
tofDev->comms_speed_khz = VL53L0X_I2C_SPEED // 100;
VL53L0X_Error ret = VL53L0X_DataInit(tofDev); //succeding
if(ret!= VL53L0X_ERROR_NONE)
{
logErr("data init failed");
return -1;
}
ret = VL53L0X_GetDeviceInfo(tofDev ,DeviceInfo); //succeding
if(ret!= VL53L0X_ERROR_NONE)
{
logErr("unable to get device info");
}
ret = VL53L0X_StaticInit(tofDev); //failing
if(ret!= VL53L0X_ERROR_NONE)
{
logErr("static init failed");
//return -1;
}
The static init function is failing at the below
VL53L0X_Error VL53L0X_measurement_poll_for_completion(VL53L0X_DEV Dev)
{
VL53L0X_Error Status = VL53L0X_ERROR_NONE;
uint8_t NewDataReady = 0;
uint32_t LoopNb;
LOG_FUNCTION_START("");
LoopNb = 0;
do {
Status = VL53L0X_GetMeasurementDataReady(Dev, &NewDataReady);
if (Status != 0)
break; /* the error is set */
if (NewDataReady == 1)
break; /* done note that status == 0 */
LoopNb++;
if (LoopNb >= VL53L0X_DEFAULT_MAX_LOOP) {
Status = VL53L0X_ERROR_TIME_OUT; <- Here it is failing. Timeout
break;
}
VL53L0X_PollingDelay(Dev);
} while (1);
LOG_FUNCTION_END(Status);
return Status;
}
The implementation of VL53L0X_PollingDelay(Dev); is as below
VL53L0X_Error VL53L0X_PollingDelay(VL53L0X_DEV Dev){
VL53L0X_Error status = VL53L0X_ERROR_NONE;
LOG_FUNCTION_START("");
HAL_Delay(1);
// const DWORD cTimeout_ms = 1;
// HANDLE hEvent = CreateEvent(0, TRUE, FALSE, 0);
// if(hEvent != NULL)
// {
// WaitForSingleObject(hEvent,cTimeout_ms);
// }
LOG_FUNCTION_END(status);
return status;
}
I think the platform layer I2C integration must be fine because data init….get device info seems to be working….even setbudget functions as well are working.
I am still not understanding what issue is this about.
Any help is highly appreciated.
Thanks,
Krishna
