Hi,

I have an SI1147-M01-EB evaluation kit.  I have downloaded the SI114x Programmers Toolkit, but I cannot get a connection to the hardware.  The quick-start guide refers to Windows 7 only, so is it impossible to make this kit work on a Windows 10 machine?

In Device Manager, the device appears as an HID (Human Interface Device) rather than under Ports or USB - is this the problem?

If I launch SI1140 Control Panel, under devices I can see COM1 or TS004A572A.  Pressing Connect with either device selected results in an error - unable to set baud rate for COM1 and unable to initialize SI114x. Function: InitSI114x for TS004A572A.

Also, when I launch the Firmware Updater, what should I choose from the evaluation board drop-down?  Module?

Can someone help please?

Thanks

 

 

 

We have used the Si1133-AA00-GM sensor for a application.I need the following information for further usage and purchase of the sensor  1.What is the Life time of the SI1133 sensor? 2.Please share the EOL detail of the sensor? 3.How to check the degradation of the sensor?  kindly support as soon as possible 

To whom it may concern, the datasheet does not include any information concerning the RoHS Compliancy for the Si7021-A20-GM1R so it can't be used as proof of RoHS Compliancy. We are using this part in one of our products and need a RoHS Certificate or some form of documentation stating RoHS Compliancy for our document control. I need this as soon as possible. It is holding up the release of a product. Thank you, Roger

Hi,

I am using si1153 to detect a thin line to pass through.

The init. code is 

void Init_Sensor(void)
{
	uint8_t conf[4];

	Si115x_Param_Set(Si115x_CHAN_LIST, channel);

	Si115x_Param_Set(Si115x_LED1_A, 0x3F);


	// Configure timing parameters
	Si115x_Param_Set(Si115x_MEASRATE_H,   0);
	Si115x_Param_Set(Si115x_MEASRATE_L,   1);
	Si115x_Param_Set(Si115x_MEASCOUNT_0,  1);
	Si115x_Param_Set(Si115x_MEASCOUNT_1,  0);
	Si115x_Param_Set(Si115x_MEASCOUNT_2,  0);

	//------  Configuration for channel 1 ------
	conf[0] = 0B00000001;  // ADCCONFIG
	conf[1] = 0B00000100,  // ADCSENS
	conf[2] = 0B01000000;  // ADCPOST conf[2] = 0B01000001;  // ADCPOST
	conf[3] = 0B01100001;  // MEASCONFIG conf[3] = 0B01000011;  // MEASCONFIG

	Si115x_Config_Channel(1, conf);

	Si115x_Send_Command(START);
}

Measurement period = 800us

Measurement time = 390us

However, there are 6/7 interrupts found within 800us.

Is the setting wrong?

Hi,

I have a Silicon Labs Si7053-EVB.

The evaluation software is written in LabView. Where can I find the LabView drivers?

Hello there,

In single measurement mode (which I assume is not doing any averaging) I  am getting  a raw value reading fluctuation of about 
+/- 40 (dec). Without bypass cap at the sensor it is about +/- 60. This was observed without magnet nearby the sensor.

I am just wondering if this is a normal sensor noise level.

Thanks.

 

 

 

 

 

Hi,

       The "sw_op" described in the Si7060 datasheet is a 9 bit number, but in the "Register Interface" description section, you can only see that the bit6-bit 0 of 0xC6 is "sw_op." Where are the other two bits?

Dear Silabs,

There are several questions to ask when using SI1175. Please help answer. Thanks. (NDA agreement has been signed)

1. Use official code, when using high power mode to turn on two LEDs. When the heart rate is higher than 140, it will crash. why?

2. How much power does the SI1175 consume? In what mode did you get it?

Hi, I am trying to get accurate UV reading from Si1133. I am planning to use 0.6mm Corning Gorilla Glass and is trying to select a telfon diffuser. According to the paragraph below, I am wondering if a standard PTFE tape like this (https://www.neoseal.net/tds/Neoseal%20PTFE%20Tape.pdf) would work? If so, is there any special requirements (color, shape, etc.) to meet? And can the tape be pasted directly onto the glass overlay?

 

Thank you!

Hi,

We are looking to use Si1133 for our application. I would like to know if this IC would be active for the next 5 years and is recommended for new designs?

Please let me know.

Thanks,

Dear all,

I am currently trying to use the SI1153 chip with 3 narrow beam infrared LEDs to detect proximity with a 50 cm range. The signal/noise ratio is pretty bad when the target is 50 cm away, in particular because of fluorescent lights flickering. Thus, I would like to narrow the viewing angle of the sensor to something like +/-45°. The lens included with the Si1133/Si115x eval board is great but too narrow (+/-5°).

Do you know where I could find a lens that meets my need ? Ideally, I would like it to be easy to mount on PCB or to insert in a hole (like a light pipe). How did SiLabs get the one that is already mounted on the eval board ?

Thank you in advance !

Hello guys,

I have a water meter with a magnet on the pointer and I would like to replace the reed switch with the SI7210.  My device needs to mark the flux as well as the reflux (clockwise and counterclockwise).  The question is: can I know the direction of the magnetic field when triggering the interrupt ?

Thanks

Hello,

               I am interfacing the sensor with msp430 controller. Here the internal ir led is used and the rest are pulled up with 4.7k resister . The interrupt doesn't get triggered for the below initialization code . why does the response0 reg resets to 0x20 when Si115xParamRead  is done. What might be the issue here??   

int16_t    retval=0,part_id=0x00,hw_id=0x00,rev_id=0x00;

//    retval  = Si115xReset();// gets command error ie response0 reg=0x30;
    delay_ms(10);
    I2C_Master_ReadReg(SI1153_Slave_Addr, SI115x_REG_PART_ID, 3, Si1153_buffer);
    part_id=Si1153_buffer[0];
    hw_id=Si1153_buffer[1];
    rev_id=Si1153_buffer[2];
    delay_ms(10);
    retval += Si115xParamSet(PARAM_LED1_A, 0x3e);
    //Si115xParamRead(PARAM_LED1_A);
    delay_ms(10);
    retval += Si115xParamSet(  PARAM_CH_LIST, 0x01);
    //Si115xParamRead(PARAM_CH_LIST);
    delay_ms(10);
    retval += Si115xParamSet(  PARAM_ADCCONFIG0, 0x60);
    //Si115xParamRead(PARAM_ADCCONFIG0);
    delay_ms(10);
    retval += Si115xParamSet(  PARAM_ADCSENS0, 0x04);
    //Si115xParamRead(PARAM_ADCSENS0);
    delay_ms(10);
    retval += Si115xParamSet(  PARAM_MEASCONFIG0, 0x41);
    //Si115xParamRead(PARAM_MEASCONFIG0);
    delay_ms(10);
    retval += Si115xParamSet(  PARAM_MEASRATE_L, 0x0c);
    //Si115xParamRead(PARAM_MEASRATE_L);
    delay_ms(10);
    retval += Si115xParamSet(PARAM_MEASCOUNT0, 0x7b);
    //Si115xParamRead(PARAM_MEASCOUNT0);
    delay_ms(10);
    
    I2C_Master_WriteReg(SI1153_Slave_Addr, SI115x_REG_IRQ_ENABLE, (uint8_t *)0x01, 1);
    delay_ms(10);
    I2C_Master_ReadReg(SI1153_Slave_Addr, SI115x_REG_RESPONSE0, 1, Si1153_buffer);
    delay_ms(10);

    Si115xStart();

Hi all,

 

I am using a si1141 sensor on a custom PCB with the sensor driven from a PIC. The application has been live for about 4 months and we currently have around 3 million operating hours from these boards. I am occasionally seeing the sensor become unresponsive which manifests itself as all messages coming back from the sensor to the PIC as zeros only. 

 

I have around 3,500 devices operating at the moment and around 1 to 2% of them are going into this mode. It seems that it can only be recovered by a hard reset of the sensor.  

 

Has anyone else seen anything like this? Obviously I can provide more details of the application etc but I don't want to swamp the thread with useless information if no-one else has seen this. 

 

Any help or insight would be very gratefully received!

 

Paul
