Hello, I am investigating if I could include a register value in the NDEF field.My goal is quite simple, check value of register 5 tamper configuration and report it via NDEF so it a user could scan the tag on their iPhone and send and SMS with the tamper seal status...Is this possible?

The driver has been successfully installed and used on my computer to communicate with the STM32F769NIH eval kit over a microUSB to USB2.0 cable at full speed (the STMicro chip being the device and the computer the host). I then took the STM CDC driver and used it for the STM32F765VI chip without making any changes to the driver (only switched out the startup code).  ​Connected the FS DP and FS DN lines to the corresponding USBC connection pins, and connected the CC pins to a USB C PD device. Upon connecting to a computer, the endpoint 0 control transfer seems to occur and the computer sees a comport and downloads the driver. However, the driver then fails to work and gives me the "This device cannot start (Code 10)" error code. Is this a difference in endpoint addresses between the chips, or does this have to do with the USBC connection? (I have seen that the endpoint address for the F769 chip are 0x81, 0x01, and 0x82. If anyone with a CDC driver for a F765 co

My current project uses "en.stm32f4_dsp_stdperiph_lib", version 1.60, which implements the finished product function using standard library. Since stemwin GUI was added to use Mipi lcd, I found only a simple DSI example in the standard library.Does ST provide an example similar to DSI STemWIN in HAL libraries for standard libraries? If so, can we get some clues? Thanks very much�?

Can TIM7 set as trigger source？​ ​​

I'm programming a L432KC Nucleo using STM32CubeMx. When a certain condition is given in my program I want the controller to reset itself instead of pushing the external reset button. For example,if ( x == 5){ \\reset the controller }Is there a way of doing this? I haven't used the watchdog concept. Is it applicable here?

I have got the example application which uses RFAL library for detecting different communications. However the sample application uses polling method. How can I use interrupt method for this. Is there any documentation available for RAFL library?

Hello,regarding the documentation in Designer or on the website the two virtual functions scrollWheelUpdateItem and scrollWheelUpdateCenter (Designer doc) or scrollWheelUpdateCenterItem (Website doc) should be generated.In my project only the first function scrollWheelUpdateItem is generated and the other one is missing. I use the ScrollWheel in a custom container.How can I add this missing function and could this issue be fixed in the designer in future?Thanks a lot,Daniel Schramm

recently I used the STM32F072 USRT3 to communicate with my peripheral， the configuration of USART3 is follow：static void USART3_Init( void ){ GPIO_InitTypeDef GPIO_InitStructure; USART_InitTypeDef USART_InitStructure; NVIC_InitTypeDef NVIC_InitStructure; /* Enable GPIO clocks */ RCC_APB1PeriphClockCmd(RCC_AHBPeriph_GPIOB | RCC_AHBPeriph_GPIOB, ENABLE); /* Enable USART3 clock */ USER_USART3_APBPERIPHCLOCK(USER_USART3_CLK, ENABLE); /**USART3 GPIO Configuration  PB10   ------> USART3_TX  PB11   ------> USART3_RX */ /* Configure USART Tx and Rx as alternate function push-pull */ GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_OType = GPIO_OType_PP; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP; GPIO_InitStructure.GPIO_Pin  = GPIO_Pin_10|GPIO_Pin_11; GPIO_Init(GPIOB, &a

I'm feeling really stupid about this. We were unable to debug in our circuit, so to check, we have a standalone STM32L021D4Px, mounted to a solderless breadboard. 3.3V is connected to Pin 14, ground to pins 9 and 1, NRST to pin 4, SWDIO to pin 13 and SWCLK to pin 14.The debugger does not see the target. The Keil IDE sees the ST-LINK/V2 OK.Clearly I'm missing something. Can anybody tell me what I'm missing?Thanks

I'm having an issue with 'patching' the new to accept longer messages than 64 bytes (USD HID limit). On page 43/44 of the AN3954 application note it describes the method of applying this patch, it also talks about a successful return code of "00 02 03 97", however I only get 0xF7 which doesn't appear in the error code list either.Longer messages still do not work.Any advice would be great.ThanksGeorge

Hi everyone, I'm using a LIS3D in my schematic. Everything works fine. I can read the register "WHO_I_AM" without any problem. BUT : I have a current consumption of 1.2 mA. Can you help me ? I don't understand how is it possible. Here is my schematic : I'm working with an I2C interface. Thanks for your help. Best regards

Hello,I dont find a graphic "consumption versus frequency" to have an idea of the slope.I am looking for different modes like run, sleep, stop and standby.Thanks for help,

Posted on April 11, 2017 at 14:49Hi,I have downloaded STM32Cube_FW_F3_V1.7.0 and I'm trying to build examples using 'System Workbench for STM32'. I have STM32F303 Nucleo 144 Development Board (F303ZE).I'm trying the following example:STM32Cube_FW_F3_V1.7.0\Projects\STM32F303ZE-Nucleo\Examples\UART\UART_Printf\SW4STM32\STM32F303ZE-NucleoI imported the project in System Workbench but the project does not build. It gives error:make all make: *** No rule to make target `all'. Stop.* Are these example projects tested and verified to work with System Workbench?* Is there any known bug with these examples?* How to import the project into System Workbench? May be the way I import is wrong.In my own custom project printf/UART is not working. So I'm trying to get this example to work such that I can use it as a reference.Any inputs might be of help to me.Regards, Pj#uart #stm32cube_fw_f3

Posted on May 04, 2018 at 00:04Hi,   I'm thinking in replace  a STM32F7 with a STM32H7 on two board that has normal CAN-2.0 transceivers. I would like to know if it will work for CAN-FD frames, keeping the baud below 1 Mbps. Ari.

Hi，Masterplatform:stm32f030C8TxI saw the data sheet as described below:My schematic is as follows:These LED lights can be lit at the same time, the program can also run normally, but their current sum has exceeded 3ma. Although it violates the description in the manual, there is nothing wrong with it. Is it okay to use it like this?Forgive my poor English proficiency。Thank you!

Hi there,I am using the STM32F373CC in LQFP48 package on my own application (not a nucleo or discovery board) with all supplies and references connected to 3.3V and decoupled as suggested by ST.The microcontroller is running as expected, I/Os are operating and I can debug my program using ST-LINK-V2/1 from a NUCLEO-L476RG board. So far everythingis well.But when I try to confure SDADC1 using STM32CubeMX-V5.0.0 with firmware package STM32F3-V1.10.0 it never returns from HAL_SDADC_Init().Reason is that STABIP bit in ISR register never gets cleared.I checked all supply and reference pins of the controller with an oscilloscope, no errors detected here. What can be the reasons for STABIP never getting cleared? My clocks are configured to use HSI RC to generate a 40 MHz SYSCLK divide that by 8 to get a SDADC clock of 5 MHz. Did I miss to enable some clocks? But that should be handled by STM32Cube firmare packages, I thought.Any hints or suggestions where to look for a solution would be very

Hello:Using IAR EWARM 7.8 for these tests. IAR provides working HAL examples for the STM32F4 Discovery boards. They have a specific example for both input capture, and PWM capture on the STM32F4 Discovery. Both examples work....both capture a 2KHz square wave in to the pins (PA9,PC7) for each example.Over to the NUCLEO-L476RG. IAR provides an example for that, both timer input capture and PWM capture. Supposed to be ready to go and "tested". Ditto for CubeMX examples, under cube's folder version "STM32Cube_FW_L4_V1.13.0". Neither of those sources work on the Nucleo board...and I have two boards that are new. I put a LED toggle in the interrupt TIMx_IRQHandler. Never lights it. What gives....anyone tried these "tested" examples? Why would HAL work on the old Discovery board, and not on the Nucleo board? Thanks....

I'm embarking on a project with the ST25 NFC chip. ST provides an XCube pack but I can't figure out how to install. MXCube complains that it can't handle the .zip file (en.x-cube-nfc4.zip). Should I have kept my old version of MXCube? I just updated to the latest..

Hi experts,I am using an STM32F429. I set in the option bytes the read protection level to 1 (with the process specified in the reference manual) and it seems that after writing of the new data into the option bytes finished the MCU automatically issues an bus fault (this occurs always). In the documentation it says that a bus fault may occur if, e.g., a debuger is connected and tries to access the protected areas, but this also happens when no debugger is attached. After resetting the MCU manually everything works fine again.Is this the normal behaviour? I coud not find anything in the datasheets/manuals so far. The only hint in this direction is the comment in the documentation of the F4Cube-HAL libs regarding option byte programming, where it states that a reset will occur and there is no code in the lib-functions to trigger this reset. (I am not using the F4Cube-HAL, i have my own).Any insights are welcome.Additions:It seems that writing a new Value thats also a Level 1 and writing

Posted on January 10, 2017 at 05:44Hi,I am developing application on STM32F0 MCU to interface with external android device (host) via virtual com port.I plan to use USB CDC class on STM32 USB library so that host device. STM32 VCP driver only available for windows. Do we need to install anything on android device in order to support VCP on STM32?For my testing, i am using stm32F0-discovery as my devkitAny assistance will be very much appreciated.#stm32f0

The FAQ states that its not possible for STM32F1 but for newer STM32 families its possible. Please clarify.
