Is it possible to read/write NDEF on mifare classic using st25r3911b?, I tried running the ndef middleware but ndefPollerContextInitialization is returning ERR_PROTO with mifare classic tag

Hi,I have a project in which I have to connect my PC to a measurement device thanks to VBA. I would like to use a mcu in order to control a component related to the device. This component is a decoder using the mcu outputs as input signals. These signals changing with time.I have to control the signals with the code controlling the measurement device. Indeed, they will be changing according to a variable used in this code. Therefore, I would like to know if it is possible to program a MCU such as a STM32L100RCT6 with VBA? And if not, is there any alternative that can help me control this kind of mcu via VBA?Thank you in advance for your help,Jay.

HiCurrently in the project, I am using a custom container and want to implement DragEvent and ClickEvent in the custom container. I follow the instructions to configure my container.hpp and container.cpp, but nothing works.I use the same method in the main interface can be used normally, do I need other configuration?Thank you in advance for your help.

Due to the global chip shortages, we need to purchase a pin-compatible (LQFP100) version of the STM32F765VIT6. Since we don't need the 2k Flash we are looking at the STM32F7767VGT6, or the STM32F746VGT6. Both appear to have the same essential architecture except for Flash and RAM size. Doe anyone know of any other significant differences other than the obvious peripheral differences? We are currently in production and need a speedy substitute.

my code is jumping into hardfault handler during/after flash write procedure.some problem with mutex or task handling, can somebody explains how to hold the thread until the flash write is complete.note: flash write functions are called inside the "below normal " priority thread.

Hi! I'm struggling to get a BLE connection to my SensorTile.Box throught a Python script. I searched on internet and i found BlueST-SDK for Python. However, this is working just for Linux (as i read on Docs). I tried several time installing "Bluepy" and "BlueST" libraries using "pip instal -name-" command. As result, several errors occurred. What can i do? Is there any possibility to use it on Windows?

Hi,I am trying to get an SPI connection working with my Arduino UNO and the ST25R3911B. I am trying to read the identity register 3Fh but am not getting a response on MISO.My setup is as follows:*VDD & VDD_IO connected with 5V from the Arduino UNO without filtering.*Ground provided by Arduino since it provides the 5V too.*Pins AGD, VSS, VSP_A, VSN_A, VSP_D, VSN_D, VSP_RF, VSN_RF, and pin 33 VSS are grounded as shown in Figure 2 or 3 in the datasheet using decoupling capacitors of 10nF and 2.2uF as stated in the DISCO and layout documents.*13.56MHz crystal is not connected for now since I am only trying to get an SPI connection working for an inital test.*Using a 10k pull-down resistor from MISO to GND since without it I saw a lot of noise on MISO after and while sending the 3Fh command to read the identity register.*I am sending 10h to register 01h before the 3Fh command so that the RFID IC knows a pull-down resistor is being used.*I am not using a particular SPI frequency since I

Hi,I have implemented a smart card in software and the ccid class to interface it via the usb, everything works correctly even for long cryptographic operations (using wtx).Now I wanted to extend the functionality of my card by adding the NFC interface and the chip I chose is the st25r3916 for possible future use as a reader as well.I started from the demo_ce.c example in X-CUBE-NFC6 (STM32CubeExpansion_NFC6_V1.1.0) and everything works correctly until operations that take a short time to be performed, operations such as signature or key generation all fail by disconnecting the card from the reader.What can I do to solve this problem? is there any way to implement the sending of the wtx packet in nfc as well?Thanks and regards.D.

we are trying to use st25r3911b to read UID of iclass HID dy card we have, we can see st25r3911b wake up once card is in range, but the rfalNfcPollTechDetetection is not able to detect any technology (we activated detection of all technologies). How can we fix this?

I used the latest official version（2021-03-31） to configure the stm32mp157c-dk2 of the optee version, and used the official tutorial to generate fip.bin and burn it to the corresponding partition, but it seems that the image is not checked,in other worlds, I did not see the successful prompt for the verification of the mirror image.

I would like to determine if this is stable enough to be the timebase for a servo loop and/or doing integration when dead reckoning.Would be great to get this this across PVT (process, voltage, temperature).Thank you in advance for your help!

In our custom board, we are using M24C16-RMN6TP EEPROM. When we tried detecting the address of the EEPROM, we are able to get the address as 0x50, 0x51, 0x52, 0x53, 0x54, 0x55, 0x56 and 0X57. But, it should be one address from 0x50 to 0x57. And we are able to perform I2C read and write in all the above-mentioned addresses. When we checked about the pin configurations in the datasheet, there were no specific pins to set the address, i.e pins were NC. Could you suggest a way to set one address for the EEPROM?

Hi,The minute hand of the Analog clock increments in hours so unlike a real analog clock the hour hand always points exactly to a digit; never in-between. This results in misreading the clock.eg: if the time is three minutes to ten, the hour hand points at nine so the clock time looks like its three minutes to nine when in fact it is 3 minuted to ten. The hour hand should have four or five intervals between hour so this doe not occur. So if the clock was in the last 10 minutes of the hour the hour hand would be 4/5 of the interval between the hours.Magnum confusion!I thought I had set the hours incorrectly as the digital clock read:09:56:20Whilst the analog clock looked like it was 08:56:20To me an analog clock should simulate analog behaviour of all of the hands. It is probably not required for the minute hand but definitely the hour hand.What do other people think?

Hello,​I made an interaction for a Flex button to call a function with TouchGFX Designer 4.15.0.I closed TouchGFX Designer and reopen the project file that I saved, the interaction is not bound to any button. (See the image below)​When I press [Generate Code] button on TouchGFX Designer, the interaction in ViewBase class is overwritten and deleted.However .touchgfx file is not changed at all, so I can see the interaction is bound to button if I open the project file with text editor.This bug does not always occur. and other interactions in the same screen or the other screen is not affected.Hope this issue would be fixed soon.​Shimpei.

I have #include "cmsis_os.h" statement in my .c file. Also Ctrl+click works in CubeIDE to get to the correct file that includes definition of the function (cmsis_os.h) and also reports correct directory (CMSIS_RTOS_V2)...Really weird behaviour, I'd kindly ask for some guidance or help.Thanks, regards Rob.

Hello,I run into problem for selecting TIM2 as my pwm output. As it turns out, it is only output capable. But I need to get processor independent 3kHz 50:50 PWM signal with no AF functional PWM.Any simple idea how can I toggle with 50% 3kHz duty cycle this GPIO? (PA15 on STM32L412C8)I Am thinking of using DMA, just have no idea how to do that, since I can't use ODR register,I have multiple pins that should not change, and with BRR BSRR, well, it is two address, so what ? Do ping pong DMA with single transfer and circular buffer ?Any ideas are welcome :)

I'm currently using TIM2 on an STM32F373 as a 32bit quadrature encoder interface, however I need to extend this to 64 bits. Can I cascade a second 32bit counter (e.g. TIM5) as a slave whilst still maintaining the ability to count up & down ? Thanks

I've edited this post to make it more useful to others.We are well into development of a board at work using an STM32F072RBT6 MCU. I just wrote a quick from scratch test using a NUCLEO-F072RB board to verify things. I'm not sure of the exact problem, but it appears TIM2 is adding 1 to the CCR. I have the timer configured that each count is 1 us, using PWM mode 1, and down-counting. If I write in a CCR of 0, I get a 1 us pulse. If I write in a CCR of 1, I get a 2 us pulse. If I write in a CCR of 2, I get 3 us pulse. You get the picture. I attached the demo project as a zip. I also setup TIM1, but used up-counting and it works as expected. main.c has some comments in it.
