HiWe are currently working on a design involving the TSV912IQ2T operational amplifier for piezo film sensor signal detection. In our previous tests using the LM358 op-amp, the design worked perfectly. However, upon switching to the TSV912IQ2T, we are not receiving the expected output. To validate the performance and troubleshoot the issue, we would like to simulate the TSV912IQ2T in our design.Could you kindly provide the following: 1.simulation file for the TSV912IQ2T.2.Any application notes or guidelines that might help us ensure proper implementation in piezo film sensor applications.3.Suggestions for troubleshooting the output discrepancies compared to the LM358 in a similar configuration. 

Hi,I am trying to write the IQ data to the SD card (i.e., write the received CTE pkt to the SD card). However, I found that Bluenrg-332ac has a cortex M0 core, which may not be able to drive an SD card. Is it possible to use this cortex M0 core for SD card writing?Thanks,Jason

Hi I'm using this device in a space design.  I just want to clarify the voltage requirements.  In all cases, I have Vdd1 >= Vdd2, as specified.  However, I'm using the device in these configurations and I want to confirm that the voltage levels are valid (it appears so from the datasheet but it's a little confusing):Vdd1=5.0V, Vdd2=5.0VVdd1=3.3V, Vdd2=3.3VVdd1=5.0V, Vdd2=3.3VVdd1=5.0V, Vdd2=2.5VVdd1=3.3V, Vdd2=2.5VAlso, is there any requirement for the power connections for the 2 halves of the part.  For instance, I have one part with Vdd1-1=5.0V, Vdd2-1=3.3V  and Vdd1-2=3.3V, Vdd2-2=2.5V.Thanks for your time,Ryan MillerChief Engineer, Digital SystemUniversity of MichiganSpace Physics Research Laboratory

Hi I'm looking for a PCB Artwork file for the S2-LP transceiver with 915MHz Band. If you have any related materials or examples (like as PCB Job file or PCB Artwork file etc..,), please share them. Thanks a lot.

Following the "getting started doc" instructions: stacked the X-NUCLEO-GNSS1A1 to the B-L475IOT1A1 Discovery board through the Arduino UNO R3 connectors, opened and compiled the example application using STM32CubeIDE, dragged and dropped the binary produced file into the BL475 board, and pressed the "reset" button I am able to get only a few results on the serial terminal, but not the desired ones as the images in the "getting started doc":Option0 -A_GNSS: Results from "Download-PR-Data,X" and "Download-RT-Data,X" are fetched after WiFi connection is established. "GETAGPSSTATUS" displays nothing, rather the serial "block" stays flashing like if its loading or waiting for something.Option1-3:GetPos: I get "Last position wasn't valid"LastPos: I get "Last position wasn't valid"WakeUpStatus: I get "Wake up status: 0"Option 8-9:GetFWVer: empty square brackets, some of them with zeros in themGetGNSMsg: empty square brackets, some of them with zeros in themOn my end, I have gone through all t

hi i have question about usage, could you help me and give me these:Full datasheets for the evaluation board for STiD135;Full datasheets for STiD337; Full datasheets for the evaluation board for STiD337;Drivers for STiD337      

I am hoping to understand whether or not this STUSB4500 PD controller on this evaluation board will default to a 5V sink level if it attaches to a standard USB-A port that does not communicate over the CC lines. I have tried this with a USB-C PD source and it negotiates a 15V contract and works fine. One of my requirements however is to get it to work with a standard PC USB-A port. When I connect that into the board using a USB A to Micro USB cable with a Micro to USB-C converter the VBUS powers, but the controller never turns on the FET to pass the VBUS out to the VSINK output. My MCU power supply operates  off of the VBUS input as it has a wide input span up to 25V, but I never see it turn on the FET to pass the 5V power out to the VSINK output. Does it not turn this on because there is no communication on the CC lines. Should it not default to a 5V contract? Can I possibly get my software engineer to set up 5V @ 500mA as a default contract over the I2C bus by setting some

Hi, I am using X-NUCLEO-BNRG2A1 mounted on NUCLEO-STM32L496. I want to implement security so I am using IRK for my ble Mac address after that no one can trace my mac address. i am new here and I used the irk flag and command like :/* Configure read root key IR on BlueNRG, BlueNRG-MS device */ret = aci_hal_write_config_data(CONFIG_DATA_IR_OFFSET,CONFIG_DATA_IR_LEN,(uint8_t *) IR);and alsoret = aci_gap_set_discoverable(ADV_DATA_TYPE, ADV_INTERV_MIN, ADV_INTERV_MAX, RESOLVABLE_PRIVATE_ADDR, NO_WHITE_LIST_USE , sizeof(local_name), local_name, 0, NULL, 0,0); // Set the device to be discoverableif(ret != BLE_STATUS_SUCCESS) // Check if the ret was succesful{printf("aci_gap_set_discoverable : FAILED!! \n\r");} 

Hi, Trying to compile one of the BlueNRG-LPS example project in Keil. And get the following errors for a few S files E.G.: osal_memcpy.S: Warning: A3912W: Option 'x' is deprecated.osal_memcpy.S: Error: A1067E: Output file specified as '..\..\..\..\..\Middlewares\ST\hal\Src\osal_memcpy.S', but it has already been specified as '.\legacyextended\objects\osal_memcpy.o'osal_memcpy.S: error: A1023E: File "assembler-with-cpp" could not be opened: No such file or directory (Please see attached image for more) I'm having trouble figuring out a solution, could anyone help with this? Thanks in advance.   

I am using STM32L562 family microcontroller. I have interfaced TCPP01-M12 with my microncontroller. I have a doubt , whether i can use this device when using UCPD in source mode, as i am unable to configure software packages for source mode(X-CUBE-TCPP). It shows that i have to enable tcpp02-03 to use ucpd in source mode. Kindly verify if support of TCPP01 in source mode is provided or not. If it is not provided what efforts will it take to use TCCP01 in UCPD source mode.  

In the Spirit1 driver code, two registers at address 0x99 and 0x9A are being written.These don't appear to be documented anywhere. Does anyone know what they do?This is the code fragment:/* Set the IQC correction optimal value */anaRadioRegArray[0]=0x80;anaRadioRegArray[1]=0xE3;g_xStatus = SpiritSpiWriteRegisters(0x99, 2, anaRadioRegArray);

I've been working with the STEVAL-STWINT1B board. I want to measure and record 2 analog signals. Only ADC1 input channels IN5 and IN6 are available as single ended inputs and are accessed by PA0 and PA1 GPIOS. They share the inputs with the microphones. Do I have to de-solder and remove the microphones to use PA0 and PA1 for analog channel inputs? Would I be able to the the opamp as well?Thank you in advance 

Hi, We want to interface the IW612 NXP module(LBES5PL2EL-923) with the STM32 MCU and use it to communicate with Wi-Fi and BLE.  We want to use the STM32 host to communicate with both BLE and Wi-Fi.Does the STM32 provide any specific drivers to communicate with the IW612 BLE & WIFI?For BLE, which uses a UART host interface, do we need any AT commands from the host side, or is another commands used?Similarly, for Wi-Fi, which uses an SDIO host interface, do we need any AT commands from the host side, or is another commands used? 

I would like to know what chip antennas are recommened to use with Spirit1 chip. Also schematics to see how matching is done and PCB layout would be of great help. Thanks

Hi, recently I got a X-NUCLEO-BNRG2A1 and I am trying to use it with NUCLEO-G070RB without success. I have created a project with STM32CubeMx assistance using SampleApp of X-CUBE-BLE2, mapping the pins of the expansion board to my nucleo board as follows:RST - PA8SPI_SCK - PA5SPI_MOSI - PA7SPI_MISO - PA6CS - PA1SPI_EXTI_IRQ - PA0The project successfully built and uploaded into the MCU, however the application does not do anything it just stuck in the function HCI_TL_SPI_Reset. I have already tried installing the DTM hex file into X-NUCLEO-BNRG2A1, however it does not solve the problem.is it a problem of the DTM software?

Hello,I hope you are well.I have a question about the certification of the “Programmable Bluetooth® Low Energy wireless SoC” from the “BlueNRG-LP” family: are they BQB certified?Thanks in advance

I've bought a S2LP dev board STEVAL-FKI433V2 as I'm evaluating the S2LP for a product revamp.Because it will be used with a legacy system I want the receive side to completely bypass the packet decoding and output to GPIO - which seems to work to a point.My issue is that sensitivity is LOW. I don't have a setup to measure it directly, but I have a key fob transmitter outputting about -10dBm. Typically this gives me a working range of 50 feet, but using this eval board I get about 6 INCHES. I'm scoping the data from the GPIO and I can see bits dropping off from the packet after literally a few inches from the antenna.I'm not sure how much of the packet engine, rx timers, blanking etc is being used? The signal has a very short preamble of 010101, a single sync pulse then about 80 bits of 10kbps data after Manchester encoding so on-chip packet detection doesn't normally work very well.Can I use the S2LP this way? 

Hi.Please can someone tell me whether Part No: M24LR04E-RMN6T/2 (RFID Transponder) is able to communicate with MiFare Desfire ?Application will be a custom designed PCB to be used as part of Prepaid payment system   Thanks

In AN5041 Rev 5, pages 26-28, there is an example programming sequence for the STEVAL-IDP004V2 master and a device on a STEVAL-IDP003V1 using ST's customized protocol (a substitute for IO-LINK).Is there a manual or tutorial  or resource page that goes through programming the boards and communicating with them with ST's customized protocol? 

Hi all,As IQ samples are used in the direction-finding feature, I am wondering how I can extract the phase information from the sampled IQ data. I tried to extract the phase by arctan(Q/I), but it changed very quickly. Is this because of the low IF architecture in Rx mode? and where can I find the IF so I can propose a digital mixer on the IQ?Thanks,Jason
