Part Number:TMDSHVMPPTKIT
Hi,
I'm developing a research on MPPT for photovoltaic systems and I became interested in this development kit. But I will not only have to implement a modified P&O as I will need to implement a new kind of controller. Does the kit have any support for that transition? Or it needs to be attached to a PID controller?
Best Regards.
Part Number:TMP117
Hi,
we're looking into using TMP117 for our medical fridge. How often will we have to recalibrate TMP117 or exchange it against a new TMP117 to maintain NIST traceablity?
I'm asking this question because I read the following here: https://www.nist.gov/pml/mercury-thermometer-alternatives-what-traceability
"3. I have purchased a calibrated thermometer. How often must I have it tested to maintain traceability?
Initial testing/validation/calibration intervals should be based on manufacturer's recommendations or past experience with a type of thermometer (typically one year). "
Best regards

Part Number:DRV110
So I just need to state I am not an electrical engineer. I have to build a circuit to control a solenoid that requires a 10 kHz PWM signal to drive it open. It is a 12VDC, 3 ohm solenoid coil, requires 2A to drive it open (2A for 0.5-5 seconds) and 1A to hold.
I have calculated Rpeak = 1 MOhm, Rhold = 400k, Rosc = 333k, and Ckeep = 20uF. My Rsense is 30milliohms.
Being that the current is 2A, does Rsense need to be sized to 24W (12volts * 2A)? I've seen other circuits online with a 1A current and use a 1/2W resistor for Rsense. What power rating should I use for Rsense in this case?
I don't have anything special in the circuit yet like LPF, anything recommendations for good practice that isn't in the datasheet?
Thanks
Part Number:TDA3XEVM
My usecase is: UC_iss _capture_isp_simcop_display. My capture source is Leopard Imaging OV10640 Camera connected to CSI2 CAM LI port.
The capture parameters are configured in IssCaptureLink_CreateParams_Init( )
Please explain the relation of following parameters:
1) System Video Interface Width 4 LANES
2) Output Parameters Data Format: SYSTEM_DF_BAYER_BGGR. Are these the pixels that are sent directly from camera to SOC ? What is this data format. According to macro it's BGGR(I think Blue Green Green Red) but comment says B G B G … G B G B ….
3) SYSTEM_CSI2_RAW12 (12 bit raw data) is configured. And also SYSTEM_BPP_BITS16 (16 Bits per pixel) is configured. What the difference? Which one is from camera to SOC ?
I'm trying to understand what is camera output. How many bits per pixel at camera output. What is data format at camera output. How does this relate to CSI2 signals connected directly between Camera and SOC. Section 3.18 of Eval Board User's Guide?

In my design the cc2642 control eeprom by spi bus.I use the example named by spimaster_CC26X2R1_LAUNCHXL_tirtos_ccs to realize it. But I can only write ten data to eeprom at a time whatever the transaction.count is. As shown as following picture,I set the transaction.count is 20. Please give me some advice.
Part Number:TPS23861
Hi Team,
I have a question about the TPS23861 PoE controller used in our ethernet switch.
When TPS being used in semi-auto mode while PoE port functionality being deactivated via switch firmware (means PWON1-4 bits in register 19h won’t get set) - we plug in a class 4 PoE device.
Then the TPS Interrupt pin is pulled low through Classification Event. Our system reads out a few registers to find out which class the PoE device has and clears the Interrupt via CoR on Detect/Class Enable register 14h. Then again the TPS is pulling the Interrupt low after new classification and system clears it again. This process repeats to a certain point where the TPS is not sending an Interrupt anymore (Interrupt pin stays high). Replugging the device does not change that. Sometimes it only takes one minute to reach this effect and sometimes it takes up to 20 minutes.
I wanted to ask if there’s any kind of counter/timer realized in the TPS functionality that keeps it from continuing the mentioned process forever?
Best regards
Simon

Hi, I'm new to the ethercat development,
and have read the document and run some sample tests.
In distributed clock ,
I can understand the 0x92c registers, time control loop, and drift compensation.
what I'm confused now for the distributed clock is the speed counter, and
what is this for and how it is measured? can you give an example?
what are these registers:
thanks
Part Number:DAC8742H
I am trying to implement HART communications using the TI DAC8742H chip in SPI mode. Host processor is a Hercules TMS570LS0432.
First off I have observed that the DAC8742h.pdf document has an error. Address for MODEM_STATUS Register is documented as 0x20 and the FIFO_STATUS Register address is 0x24, however, I have observed that they are the opposite. Actual behavior is address for MODEM_STATUS Register is 0x24 and the FIFO_STATUS Register address is 0x20.
After system boot I send a single character through TeraTerm, for example a ‘1’ (hex 0x31). My device receives an IRQ. I read the MODEM_STATUS Register and FIFO_M2D Register; the DAC8742 reports that it received 0x31. So far, so good. From TeraTerm I send a ‘2’ (hex 0x32); I get an IRQ . I read the MODEM_STATUS Register and FIFO_M2D Register; the DAC8742 reports that it received 0x31. Not good. It should be 0x32. In fact no matter what character I type the modem reports that I got a 0x31. The DAC8740H.pdf states that the buffer will be cleared when I do a SPI read command. It does not.
I reboot, send a single character 'a' (hex 0x61). My device receives an IRQ. I read the MODEM_STATUS Register and FIFO_M2D Register; the DAC8742 reports that it received 0x61. Again, good. From TeraTerm I send a ‘b’ (hex 0x62); I get an IRQ . I read the MODEM_STATUS Register and FIFO_M2D Register; the DAC8742 reports that it received 0x61. Not good. It should be 0x62. In fact no matter what character I type the modem reports that I got a 0x61.
Any advice would be appreciated.

Part Number:TMS320F28374S
Hi,
I'm using this uP to control a 10 kw 3 phase buck. I get strange Udc value on power off of the converter.
I measure current and voltage in this way:
SDFM is free running -> CLA gets data via SDFM data ready interrupt-> CLA computes running average of current and voltage for 3 switching periods -> gives result to uP.
The running average code is:
Sum = Sum - Buffer[Pointer];
Buffer[Pointer] = DataFormSDFM * Scale;
Sum = Sum + Buffer[Pointer];
Result = Sum / (NrOfSamples +1);
if(Pointer >= NrOfSamples){
Pointer = 0;
}
else{
Pointer = Pointer +1;
}
(I'm using float32 for Sum,Buffer,Result,Scale and Uint for pointer)Now this gives correct result when I use it to measure current (all current measurements are on SDFM1).
But for voltage (measured with SDFM2 ) I get result -600V (or other random big negative number) when I turn off my converter. So I addded
if( Result< -10){
__mdebugstop();
}
at the end of the task that is triggered by SDFM2. And sure enough the second I stop my converter it brakes here.
I get all normal values in Buffer, in it I have 33.8 +/- 0.5V. But the values of Sum is -4614.4. And then it slowly in a couple of minutes goes back to 0 +/-0.5v.
As there is no strange big number in Buffer I thing SDFM is ok, measures ok when the converter is running. My question is now:
1) Why does the large negative value of Add suddenly happen?
2) Why does it go down to 0? Floating point error in calculation?
3) How to fix this?
