Hardware: PSoC 4 Pioneer Kit 042
2x TLE493D 3D Hallsensors
The problem is that after I flash or reset the board, the sensors are sometimes (almost every second reset) not initialized correctly.
After the reset I get a normal communication or only the first sensor is initialized and the second one gets stuck and there are only interrupts on the SDC line.
Although I only have a delay of 150 µs between the initialization of the first and second sensor in my source code, I measure a delay after the reset of the board of 60 ms as shown in the picture.
The reset() function resets both sensors by sending 0xFF twice and 0x00 twice with a delay of 30 µs to the I2C bus as described in the User Manual.
After that I initialize the sensor one with the address 0x22 and then the Vcc of the second sensor power up and init the second sensor with the address 0x35
// --------------------------------------------------------- /********************************************************* * Configuration and initialization of the TLE493D sensor ********************************************************/ reset(); // Power Off / Power On the TLE493D VDD_sensor_Write(0); TLE493D_Init(TLE493D_AW2B6_I2C_A1_ADDR); VDD_sensor_Write(1); CyDelayUs(150); // Small Delay TLE493D_Init(TLE493D_AW2B6_I2C_A0_ADDR); UART_PutString(" Beginne mit der Kalibrierung "); UART_PutCRLF(); CyDelay(100);
Why does this error happen and where does the 60 ms delay come from?
I have this Philips One Blade trimmer (disassembly video) and I have probably by mistake tried to charge it with charger from the older Phillips shaver which had almost identical connector but 15V instead of 4.3V used by this one - the result is it can't charge. I opened it and there is one burned component on the PCB, but I can't identify what is it (I am not much of electronics expert).
I would be glad for help with identifying that component or a replacement alternative to repair the trimmer.
Solution summary: The part was diod in SOD323 package. I replaced it with 1N4148WS-SOD323 and it seems to work. Thanks for all help.
we purchased TLE493DW2B6A0 samples from digikey and built our system prototype.
everything works with multiple of TLE493DW2B6A0 sensors.
the I2C address we used for TLE493DW2B6A0 is 0x6A / 0x6B.
now, we purchased TLE493DW2B6A1HTSA1 and used address 0x44 / 0x45 and it does not seems to work.
it seems to ignore the read/write command as if the address is not intended for it.
Can you please advise if there is anything else that we are missing besides setting the address to 0x44/0x45?
BTW, when driving to 0v on CLK and Data line, what is the minimum acceptable voltages? is it 0.4v max?
our Output low Voltage is about 0.48v. is it acceptable?
please see the attachment.
Thanks and Best Regards,
Could any one support on the below query,
We have purchased DEMOPOSITION 2 GO Radar Development Kit for the Traffic Monitoring, Object Speed range detection, including of SLVD functions for one of our new product development purpose.
Hence please advise this Development Kit DEMOPOSITION 2 GO can be used in Windows and Linus OS application,
Thanks in Advance.Show Less
in document <Out of Shaft with magnetic 3D sensor>:Out of shaft
"The sensor outputs the magnitude of magnetic field.But the corresponding maximum and zero-crossing points of the SIN and COS signals do not occur at the precise distance of 90°. The difference between X and Y phases is called the orthogonality error.
There is another more accurate way to determine the orthogonality error. The orthogonality can be calculated
out of the magnitude of two 90° angle shifted components. Possible angle combinations are 45° and 135°, 135°
and 225°, 225° and 315° or 315° and 45°."
Does "two 90° angle shifted components" mean any angles that has a 90° angle shift?
if not,only the "Possible angle combinations" makes sense,45° and 135° for example,how can I determine the 45° and 135° of a magnet?Show Less
Having issue with Infineon TPM v2.0 complicating Windows 11 update! I have a brand new Intel i5 desktop pc (Asus D700SA) and I'm attempting to update to Windows 11.
The Microsoft update process balks and I get a message stating that I must MANUALLY UNINSTALL my Infineon TPM. My TPM is version 2.0 which Microsoft says is OK in order to update to Win11.
Anyone else experience this? What's up?!
GreenSoft Technology, a leading provider of environmental compliance data management services and software for the global electronics industry (http://www.greensofttech.com), has been contracted by Basler Electric to collect compliance data on parts purchased from your company. Please refer to attachments for a letter of authorization from Basler Electric and a list of part numbers.
Please note that Basler Electric might not purchase directly from your company but via a reseller or distributor. In addition, you may need to collect material or compliance documents from your suppliers such as raw material manufacturers to fulfill this request. Your support to Basler Electric is highly appreciated.
If you think we reach out to you by mistake, please let us know so we will not follow up with you anymore.
For these parts, we will need the following: (Please note – if you think the compliance information can be obtained from your web site, please mark “Web” for those parts in the attached Excel file)
• Full Material Disclosure (FMD), MSDS or similar document in your standard format if available
• Compliance statement for REACH SVHC: REACH SVHC 219 or 211 - if you don’t have the REACH SVHC compliance statement from your company, we have attached a compliance template for your reference.
• If reportable SVHCs are identified, please provide the SCIP data (SCIP – per Waste Framework Directive 2008/98/EC, amended by Directive (EU) 2018/851)
Please also populate the Excel spreadsheet with the following information:
• REACH SVHC 219 status (whether the product contains any SVHCs [Substances of Very High Concern] or Substances of REACH - Annex XIV). If a product contains any SVHC, please provide the substance name and concentration, as well as future plan to eliminate its use.
Generally, the parts applicable for 6a/6b/6c RoHS alloy exemptions would form an article, such as a pin, connector shell, standoff, screw, or bracket. Therefore, Lead concentration of such parts is likely to exceed 1000ppm at Article level, which needs your further support to provide the SCIP information. However, if you confirm your products are SVHC compliant, please provide the Article Name.
If you cannot recognize a part or it's incorrect, please indicate such in your feedback.
Please respond by November 08,2021 or provide an expected date of completion and we will follow up. We may contact you if any clarification is needed.
