OPT3101: measure phase always zero

TI007100

Part Number: OPT3101

I try to get some measurement from the sensor.

I call calibrationSession_firstTimeBringUp() and I get these:

Then I call a modified calibration function by fixing the temperature at 25, I got these. The phase number is always 0 whether I put something in front of the sensor or not.

I notice that there is a function that trigger the phase offset measurement, but reference distance is always 0 when it is called in those calibration functions.

this->measurePhaseOffset(&this->calibration->phaseOffset[indx++], c0, c1 ? 'h' : 'l', refDistanceInCodes)

If I want to use it to measure distance, what reference distance I should put?

Hi,

Have you set the COM port in the hostController? Can you do a quick test to make sure I2C to the device is working properly? You can run printf on one of the device registers accessed through dev.reg.REGISTER_NAME

Best,

Alex

Hi Alex,

Forgot to mention, I have implemented the i2c read and write in the hostController.

I tested the read and write and it is functioning properly. I have printed out all i2c read and write as follow, with register_value.

I noticed that register "A" always read 0 and register "4" always read 170000

Hi,

Could you share the code you are using?

Best,

Alex

Hi Alex,

This is the code I use for i2c read and write.

void hostController::writeI2C(uint8_t address, uint32_t data) {

	uint8_t trial = 0;
	uint8_t writeData[] = {0,0,0,0};
	uint32_t er = 0;

	writeData[0] = address;
	writeData[1] = data & 0xff;
	writeData[2] = (data >> 8) & 0xff ;
	writeData[3] = (data >> 16) & 0xff;

	printf("->i2c trying to write %x_%x\n",address,data);

	er = HAL_I2C_IsDeviceReady(&hi2c1, 0xB0, 1000, 1000);
	if(er == HAL_OK)
	{
		while(trial < 99){
			er = HAL_I2C_Master_Transmit(&hi2c1, 0xB0, (uint8_t *)&writeData, 4, 1000);
			if(er == HAL_OK)
			{
				trial = 99; // printf("i2c sending ok!\n");
			}else{
				er = HAL_I2C_IsDeviceReady(&hi2c1, 0xB0, 100, 100);
			}
			trial++;
		}
		if (er != HAL_OK){
			printf("i2c sending error ...\n");
		}
		HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_RESET);
	}else{
		printf("i2c not ready ...\n");
		HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_SET);
	}

}

uint32_t hostController::readI2C(uint8_t address) {
//	uint32_t i2cReadValue=0;
	uint8_t trial = 0;
	uint32_t returnData = 0;
	uint8_t  readData[] = {0,0,0};
	uint32_t er = 0;

	er = HAL_I2C_IsDeviceReady(&hi2c1, 0xB0, 1000, 1000);
	if(er == HAL_OK)
	{
		while(trial < 99){
			er = HAL_I2C_Master_Transmit(&hi2c1, 0xB0, (uint8_t *)&address, 1, 1000);
			if(er == HAL_OK)
			{
				er = HAL_I2C_Master_Receive(&hi2c1, 0xB0, (uint8_t *)readData, 3, 1000);
				if(er == HAL_OK)
				{
					trial = 99;
					returnData = readData[0] + readData[1] * 256 + readData[2] * 256*256;
					returnData = readData[0] + (readData[1] << 8) + (readData[2] << 16);
				}else{
					er = HAL_I2C_IsDeviceReady(&hi2c1, 0xB0, 100, 100);
				}
			}else{
				er = HAL_I2C_IsDeviceReady(&hi2c1, 0xB0, 100, 100);
			}
			trial++;
		}
		if (er != HAL_OK){
			returnData = 0; // 0xFFFFFF
			printf("i2c reading error ...\n");
		}
		HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_RESET);
	}else{
		printf("i2c ... ... ...\n");
		HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_SET);
	}
	printf("->i2c trying to read %x_%x\n", address, returnData);

	return returnData;
}

Hi,

Are you able to share the full code? I am trying to see the functions you are calling in main.cpp and any modifications you have made to be able to review this and get the full picture.

In i2c i see the print statement doesn't match the printout you shared earlier: "i2c trying to read %x_%x" vs "i2c read" in the printout.

Best,

Alex

Hi Alex,

Attached is my project files in zip.

I modified a calibration function to call measurePhaseOffset, I expect to see some random numbers even without calibration.

But I got all zeros from registers 8, 9, and A.

Hi Alex,

While you are looking at my code,

Can you let me know what the function measurePhaseOffset() or measureAndCorrectInternalCrosstalk() will return if I set those initialization registers according to the SDK?

If I always get zeros is it normal? or I should at least get some random numbers?

At least I can know whether the hardware or the code got problem.

Hi,

You should not get all zeros. Those methods have no return (void) but they modify the PhaseOffsetC class and CrosstalkC class respectively. Then the printout that you see is from running the report() function contained in those classes. The report function prints all the variables stored in the class.

This is in simple terms the order you would want to run them: initialization then measureAndCorrectInternalCrosstalk() then report()

If you are running report without running the measureAndCorrectInternalCrosstalk or measurePhaseOffset or another method like this then it could be that you would see zeros. Also the class you are printing should match the class passed to the measure method.

Best,

Alex

Hi Alex,

Yes, I tried to call report within the OPT3101::device::measurePhaseOffset function and the phaseOffset is still zero.

I checked the i2c read and write log and noticed that some registers will fall back to the default values after some time,

even though an immediate read after write has confirmed that the registers are successfully written,

for example, register 07, 02, 78, 2B, 2C, 80, etc have fallen back to the default values.

I checked the power with oscilloscope and it's stable at 3.3V, and these read and write completed within one second. So I think there is no reset happening in between.

What other reason could cause the registers to always go back to default values?

Thanks for this info. Were you able to check the I2C lines as well during these operations to make sure the reads are actually happening? It looks like I2C is working from this so in that case only reason to get default values is if the device was not configured before reading. Were you able to check on I2C lines with scope to confirm both that the device registers are written during the config stage and that they are read back afterward?

Best,

Alex

This is my write and read back of the first three registers, the waveforms look correct, but the read back always go back to default value.

Hi,

I checked using your config and I was able to configure the device and perform crosstalk calibration.

Also I noticed glitches on the I2C waveform you sent. Could this be causing issues and do you know where the glitches come from?

This seems to be an issue in your i2c read/write as far as I can tell. Please let me know if there are any other tests you think would be helpful to run if we need to narrow this down further. The latest update to the SDK we are about to release can run on a TI MSP launchpad if this would be helpful for you to get it running on known hardware or as a first step in debugging the issue on your system.

Best,

Alex

Hi Alex,

Thank you for your checking.

I guess there might be problem with my hardware. Let me fabricate another piece of sensor board and try again.

Hi,

Do you know what the problem was. We have a lot of layout guidelines in our system design doc so if you are spinning a new board wanted to mention to make sure you get the best performance. If you share layout/schematic I can also check your design for you before you rebuild.

Additionally, we have a further layout recommendation to improve performance that involves putting -5V instead of photodiode ground. -3.3V also works if 5V supply is not present. If you would like to add to your new board, I have attached below
