Solved

I have two ISO 14443-A tagsTag 1 --> UID = 2DBADC81Tag 2 --> UID = AE3A6F99And I tried anti-collisions with two tags in field.The sequence is as following:>>> REQA "26 07"<<< ATQA "80 05 04 00 28 00 00">>> Anticollision 1 "93 20 08"<<< Answer anticollision 1 "80 08 AF BA FF 99 EA B8 00 00"According to response B8 00 00, collision detected in index 0 byte and on index 0 bit.Then I tried to get Tag 2 UID as following:>>> Anticollision 1 "93 20 00 08"<<< Answer anticollision 1 "90 07 FD 9F AC 07 B3 00 02"The result is not any Tag's UID.How do I send correct command strings to get Tag 1 and Tag 2 UID?Thanks.

Hi,I am trying to upload a code to my SPC570S-DISP development board, but I am having an issue with the debugging tool UDE. I searched for this issue in the forum and I have tried all the solutions given and none of it work. When I try to debug from SPC5Studio I get this error,And when I try to use the UDE STK tool I get this error,Message from component 'PpcJtagTargIntf' :Can't connect target !Message from component 'PpcJtagTargIntf' :No JTAG client found !Please check:- target power supply- JTAG cable connection- target configurationI have created a case with ST, and so far no one has been able to figure out what the problem is. As I saw from the posts in the forum, many users are having this problem. Please be kind enough to look into this matter.

I bought a NFC board STEVAL-SMARTAG1. I tested all functions and all were working fine.I downloaded the version 3.0.0 of FP-SNS-SMARTAG1 there is avaliable at https://www.st.com/en/embedded-software/fp-sns-smartag1.htmlAfter I flash, the app read the first value correctly, but after that all values frozen with the first value. Everytime that I mass erase the flash and record again, the NFC sensor answer correctly only the first time and after freeze the values. 

Hello! If I write less than 12KB #MSD works fine. If I write more than 12KB, Windows7 will ask me to format the drive. If the MSD is not reconnected to the PC, everything works fine. Everything breaks down if Ireconnect the device to the PC. Please tell me what could be wrong?I am using flash with page size 264 B (2048 pages) [AT45DB041]The defines looks like this  STORAGE_BLK_NBR               1024 STORAGE_BLK_SIZ                  512The write operation looks like thisint8_t STORAGE_Write_FS(uint8_t lun, uint8_t *buf, uint32_t blk_addr, uint16_t blk_len){  /* USER CODE BEGIN 7 */  AT45dbxx_WritePage(buf, 256, (uint16_t)blk_addr*2);  AT45dbxx_WritePage(buf+256, 256, ((uint16_t)blk_addr*2)+1); &nb

HelloI did some basic testing to set up, write code and program the STM32 F103 (bluepill) with the STM32CubeIDE and everything worked fine!In a project I would like to design my own PCB and use the L152C8T6 chip. So I purchased some new chips from Digikey, solder the chip to a breakout board and connect it to STMicroelectronics ST-Link v2 (as I did with the F103) But with the L152 chip it seems like I can't program the Flash memory at all. But in some way I can use the system memory.When in debugging mode this message appear and the LED is not blinking when I run the code on L152 with Boot0 connected to ground.With Boot0 high and Boot1 to ground the LED is blinking when I run the code but another message appear. And the LED do not blink when the chip is powered up again. With F103 everything works fine. As the pin out is the same for F103 and L152 I also tried to solder the L152 chip to the bluepill board, but with the same result. I also know that the L152 chip is new out of the box a

How to update stm32 h750 firmware by uart in ubuntu terminal?Is there any open source ?I found stm32flash tool, but it can not support stm32h7.Is there any other option?

Hi everybody , I am not sure about am I writing to the true title but anyways I am asking. I am trying to read data from LSM9DS1 sparkfun IMU sensor using HAL i2c with STM32F4 discovery board. I was succesful and I was getting datas, then something happened and my board start not working.I am not changing the code but it sometimes work sometimes don't. I try to just read device's adress with the code below to be sure problem is not about code. There is same problem for that code to (code is sometimes working sometimes don't). I am trying to erase device memory with utilty occasionaly. 65% of time it erase device memory but other times it gives "device couldn't find " error.What could this problem be caused bye? I changed jumpers and STM's cabel but problem is still same.Adress finding code : for(Adress=0; Adress<256; Adress++) {  if(HAL_I2C_IsDeviceReady(&hi2c1, Adress, 1, 10)==HAL_OK)  {  break;  } }

Posted on August 08, 2017 at 14:40Hi,I have the ST S2-LP transceiver both transmitting and receiving just fine however i'm struggling to put the chip into a continuous wave mode.. from reading the data sheet i have configure the following :  To set the continuous wave the TXSOURCE field (of the PCKTCTRL1 register) must be set to 0x03To set the continuous wave the MOD_TYPE field (of the MOD2 register) must be set to 0x70Is there any additional registers i should be aware of in order to configure continuous wave mode?ThanksEd

I am using STM32F769I-DISO board with an MX25L51245G QSPI chipAs I understand it, I must erase before writing. So if I have 100 bytes of date on the QSPIand I want to change byte number 51 in my 100 byte data I should first eras this location.However the only function I can use for erasing is BSP_QSPI_Erase_Block(). I I want to keep the rest of the data unchanged, I must first read the unchanged data so I can save it after the erase operation. But I hav no idea how big is this block and therefore how much unchanged data I have to keep in RAM and rewrite after the erase. So How large this bock is ?

Hi, our customer is in search for a economical solution for a gadget posistion sensor, that senses 2 positions: the gadget is in standing or in laying positions. What can we suggest?

I've had some issues to calculate the correct VREF+ voltage for the ADC on an STM32L476RGT6 MCU. After some investigation, I isolated the cause to be that I called `HAL_ADC_DeInit()` on ADC2 after I used it during setup before the main loop. If I just remove the call to `HAL_ADC_DeInit(&hadc2);`, ADC1 reads the vrefint channel correctly.Any ideas? I can just keep ADC2 initialized, but the application will need to consume as little power as possible, since it will be powered by a battery and solar panel. Is deinitializing the ADC actually going to save power, or doesn't it matter?Attached are the main.c and stm32l4xx_hal_msp.c files for my minimal reproduction project. If I comment the call to `HAL_ADC_DeInit(&hadc2)` on line 132 of main.c, vrefint is read correctly. If I just add that line back and change nothing else, vrefint reads 2-3x too low.

Hi all;I have developed an application where there is a simple SrollWhell with a custom container, in which there is a icon and a number which content depend of the value of the current item selected, so that is my problem:I see that the current item selected is changing sequentially following the scroll whell but the icon and number goes a step back from this.Code:This part is right: void ScreenSetSubsystemView::scrollWheellistSubsystemUpdateItem(MenuElement& item, int16_t itemIndex) {        currentItemSelected = scrollWheellistSubsystem.getSelectedItem(); where currentItemSelected is working fineThis part is what I wanted to fix:void MenuElement::setIcon(int SubsystemType, int SegmentNumb) {      switch(SubsystemType)    {        case 0:       &nbs

Hi, I'm trying to build a Yocto-Linux for an specific STM32MP157 board. I was working with "thud", but now "dunfell" is required, as it is supposed to be long term stable.The system is built after ST's manual:https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machinetf-a-stm32mp-2.2u-boot-stm32mp-2020.01The Device Tree was adapted and Bitbake is compiling it. But now system get stuck while it executes the TF-A Boot (from SD).Is there any way to debug or get the reason for image load fail?When I try to flash it via STProgrammer a "Panic at PC" appears.Thanks in advance for any advise!KaiNOTICE: CPU: STM32MP157AAD Rev.B NOTICE: Model: STMicroelectronics custom STM32CubeMX board WARNING: VDD unknownINFO: Reset reason (0x17): INFO: Power-on Reset (rst_por) INFO: Using SDMMC INFO: Instance 1 INFO: Boot used partition fsbl1 NOTICE: BL2: v2.2-r1.0(debug):v2.2-dirty NOTICE: BL2: Built : 13:36:23, Oct 22 2019 INFO: Using crypto library 'stm32_crypto_lib' INFO: BL2: Doing platform setup IN

I've got a NUCLEO-L073RZ, STM32CubeIDE and CubeMX are installed (locally on Linux).In CubeIDE, I've installed the MCU package for STM32L0 (Help > Manage Embedded Software Packages).I can even see that it has created a "Repository" directory and the STM32L0 files (examples etc) are all there.However, whenever I open the STM32 Target Selector (from either CubeMX or CubeIDE) and select the NUCLEO-L073RZ board, there are no examples for that board in the Example Selector.I just want to be able to play around with the various different examples etc that are provided for this board as part of the MCU package, instead I've got nothing.Help please!

Hi,I want to implement I2C communication between PSOC and ST.I've configured PSoc as I2C Master and ST as I2C Slave. I've succesfully transferred data from PSoc to ST but I'couldn't read data from ST.Here's the details about my implemention.When I use I2C_Write_Data function on PSoc side, I didn't encounter a problem about the data transmission to ST from PSoCI'didnt implement I2C Slave on ST side before. I may have used wrong APIs or made some configuration mistakes.I've attached the images about the implementation. (Codes and Configuration). I'll be appreciated if you illuminate me about this problem. This is my first post on this web site so that please ignore my faults about this topic that I have )Have a nice day..1- ST I2C Slave Code2- St CubeMx I2C Slave Configuration3- Cypress I2C Master Functions 4- Cypress I2C Configuration

I know that there are a lot of questions and request for graph widget, yet there is no dependeble answer has been provided. It seems that there was a graph widget in previous versions, unfortunately not available now. I wonder if there is any ready to use graph widget that I can add to my project. The most needed feature is the ability to be updated and be able to shift the graph to the left side. The rival product (STEMWIN) has this feature.

The STM32F0Discovery board comes with accompanying example source code, traditionally. However, now, the relevant download page advises that this is all provided by STM32Cube, but it is not. There is NO example code in the STM32CubeMX / IDE for this board.What to do? How can I get the example source code for this board in the age of STM32Cube?Thanks.

Helo.I have a Nucleo-32 development board with STM32L432KC MCU. In RM0394 , chapter "Real-time clock (RTC) applied to STM32L43x/44x/45x/46x devices only" I found this: "Output functions: RTC_OUT which selects one of the following two outputs:– RTC_CALIB: 512 Hz or 1Hz clock output (with an LSE frequency of 32.768 kHz)......RTC_OUT, RTC_TS and RTC_TAMP1 are mapped on the same pin (PC13).......In addition, it is possible to remap RTC_OUT on PB2 pin..."But in STM32L432KC datasheet ,chapter Pinouts and pin description, I can't found pins PC13, PB2. Moreover, in CUbeMX when I select STM32L432KC MCU ,on RTC tab in Pinout & confiruation, I found no anything about RTC_CALIB output. Where is my mistake or datashhet missunderstanding ?Best regards, Volodymir.
