At present, there is no mature NFC WLC function, so can I complete the wireless charging function through ST25 and STWBC86? ST25 completes the transmission of information, and the electric energy obtained by STWBC86 based on Qi supplies power to MCU?As shown on page 5 of https://www.st.com/resource/en/product_presentation/ST25_NFC_presentation_for_Wireless_Qi_charging_protection_applications.pdf , complete the battery charging of the ST25.

I want to setup an system with 4.3" 480x272 LCD Working with LTDC with external flash (External Flash Loader)Can we directly interface an existing QSPI Loader if yes, Then Which one.

I should make an application with NFC where the entire circuit is powered by energy harvesting.For this reason I thought of using the ST25DV and I have already purchased the X-NUCLEO-NFC07A1 and X-NUCLEO-STM32L476RG.I have successfully obtained the energy harvesting of the antenna and can light the LED, now I want to use the energy of the antenna to wake up the MCU (L476), what do I need to do?I have tried to connect VCC with EH pin, but L4 is not waking up, what should I do to power the antenna to the MCU (L476) instead of the ST-LINK USB

I understand that in order to prevent wireless charging from affecting the ST25 tag, capacitive elements are added inside it. But are there any examples of wireless charging through ST25 combined with Qi?

i am finding issue like my application is not working in stm32cubeide 1.13.2 but it works in 1.8.0.Please help in solving this .  

Hi,I use the BFA001V2 board as a counterpart for testing IO-Link Master with BLOB transfer. A problem was detected while reading a BLOB.When using BFA001V2, after 15 successful data transfers (flow_control set to 0x2F), an invalid flow_control with a value of 0x30 (last frame) is sent. (However, the total size of the blob must be 16 KB!).According to the IO-Link specification, flow_control should cycle from 0x20 to 0x2F, after almost all bytes have been sent, the Last_block command (0x30) should be sent with the last block of data. Could someone check the stack on BFA001V2?Thanks in Advance D.Krush

Hi, i am using STM32F401RE Nucleo board and i want am using I2C channel in standard mode which is upto 100KHz but i due to little long length of communication cable, i want my I2C frequency to be around 20KHz. I am using HSI only as clock source.This is my function to use I2C channel.void i2c_init(){// I2C3 RCC CLK enableI2C3_CLK_EN;// Freq setting 16MHzI2C3->CR2 |= (16 << 0);//CCR configurationI2C3->CCR = 0x50;// T-Rise configurationI2C3->TRISE = 0x17;// Set OAR bitI2C3->OAR1 |= (1 << 14);// Peripheral EnableI2C3->CR1 |= (1 << 0);}

Hey, I am currently trying to get my own hardware to run on STM32 Microcontrollers. In this case, I am using a F103RET6, LQFP64 package. It is being used with very improvised hardware, as a proof of concept only. The layout looks like so, made in Kicad. Please be kind, it's my first rodeo. I am aware of the lacking of decoupling, filtering etc - as said, it's a prototype, I wanted to keep it as simple as possible.I am giving the circuit 9V on the left two solder pads, that are then fed into a 3.3V regulator (500mA max). It works fine up to here.Now there are two goals: I want to have the LED (above the 220Ohms Resistor) blink so I know flashing software (a two line program that toggles PA9) worked, and ultimately test the second circuit, which is a MOSFET driving a load. At this moment, there i no such said load soldered in yet. The planned-for oscillator is currently not in use, I want to try it first with the internal resonator as to not overcomplicate things. For a better view of pi

Hey, I have the ST25DV64KC-DISCO discovery kit, and I want to program it such that whenever an NFC-enabled mobile phone comes in contact, the phone will connect to a Bluetooth address that will be given inside the firmware code. So can somebody please help me with things like which software to download, how I will be able to open the firmware file of the ST25DV64KC-DISCO, name STSW-ST25DV002, and what portion of the code we need to change? Can someone please give me step-by-step instructions?

Hi everyone,I am struggling to understand why the provided example seem not to behave as expected:upon startup, when the gap is detected, the generated Reference_position (TDC) turns out to be localized 1 tooth AFTER the calculated one (angular ticks math), even if the values written to the TBU_CHANNEL1 register are correct. It looks like the match-value is only loaded into the CCU register of the ATOM channel only 1 active edge AFTER (This could be overcome with a one-time only -cold boot- compensation btw).but it's not over: after a lock-loss scenario (take 1 tooth off the crankwheel, e.g.) the resynchronization procedure is carrried out following the same steps as on startup but this time (oddly enough) the Reference_position (TDC) ends up 3 teeth (angular position) BEFORE where it is expected. There must be something with the CPU loading the CCU register values for next matching... Is there anybody running into similar issues on this specific platform? How did you get over (if

The MCWB 6.1.2 doesn't allow the configuration of of both hall sensor and quadrature encoder as speed/position sensors in main/auxiliary speed sensor configurations. It looks like the only conflict is in timer input pin allocation, but it seems like an artificial limitation that is somehow dictated by the project generator's contraints. The current project I refer to is using the NUCLEO-G431RB, but I tried this on many board/CPU platforms, including those that had more timers and many more pins.What is the limitation here? Why aren't the timer peripheral usages more configurable? Is this constraint somehow encoded into template files that would be reasonable to edit?

I am using TouchGFX 4.20.0 library. We are storing all the Fonts and images to the external memory. During the initialization as per the selected language we are caching the respected Fonts and successfully load the fonts and able to see correct text. We also cache all the images upfront. But while our display module is receiving large number of CAN messages on the CAN task sometimes we observed the few texts on the screen becomes garbled. The issue comes only for text we did not see any issue while drawing the images. As we cache both the fonts and images upfront during the initialization though we are seeing the issue with text(fonts).

I have seen the Digital PFC section in MCSDK 6.1.2 but i do not get an option in the project i have selected for the B-G431B-ESC1 project. How can i enable it? How important is this Digital PFC? In my testing i get around 0.6. 

I am struggling to find a good way to identify the two COM ports the STLink-V3PWR provides. One is for direct communication with the power measurement unit and the other is connected to DEBUG for the target device(VCP).We need a easy way to identify the DEBUG UART port of the STLink-V3PWR. When performing the "-l uart" command with the STM32_Programmer_CLI.exe we receive two identical outputs for both ports. This is not the case with the STLINK-V3SET, because we get an easy identifyable description "STMicroelectronics STLink Virtual COM Port". In the example below, how do I distinguish between COM20 and COM21? There must be a better way than opening both ports and checking which one responds to the "version" command.Example Outputs:STLINK-V3SET"C:\\Program Files\\STMicroelectronics\\STM32Cube\\STM32CubeProgrammer\\bin\\STM32_Programmer_CLI.exe" -l uart-------------------------------------------------------------------STM32CubeProgrammer v2.14.0-------------------------------------

Hi all,I have two STEVAL-MKI220V1 sharing the I2C1.Days ago, I had one kit working with Nucleo-767, so now I added another STEVAL-MKI220V1.After wiring up the kit2, I cloned all the code snippets of kit1 and rename it for kit2 with a number '2' as the suffix of all the variables.Then I added the write config lines as follows: (also changed that the Psense1_ADD = 0x5C (Gnd), Psense2_ADD = 0x5D (VCC))ret_hal = HAL_I2C_Mem_Write_IT(&hi2c1 ,Psense1_ADD,Psense1_REG_CRG1,I2C_MEMADD_SIZE_8BIT,Psense1_CReg1W,1); // 1Hz reading of Pressureret_hal = HAL_I2C_Mem_Write_IT(&hi2c1 ,Psense2_ADD,Psense2_REG_CRG1,I2C_MEMADD_SIZE_8BIT,Psense2_CReg1W,1);With these 2 lines, the kit2 doesn't work. The text box of my HMI shows blank.If I commented either one of it, as follows: (emphasize, "commented either one line")ret_hal = HAL_I2C_Mem_Write_IT(&hi2c1 ,Psense1_ADD,Psense1_REG_CRG1,I2C_MEMADD_SIZE_8BIT,Psense1_CReg1W,1); // 1Hz reading of Pressure//ret_hal = HAL_I2C_Mem_Write_IT(&hi2c1 ,Pse

Hi,I have a STM32G491 based design with three differential shunts, routed to the three Op Amps of the MCU. I would prefer to run the Op Amps in standalone mode. This would allow me to have a low pass filter (cap across negative and output) and I would also be able to fine tune the opamp gain. I understand that this is not possible with 2 ADCs due to limitations in amplified signal routing, but it would be possible with 3 ADCs.It looks like the MCSDK 6.1.1 ships with a promising r3_3_g4xx_pwm_curr_fdbk.c file. How to configure this current measurement topology with the MCSDK 6.x? I have a JSON spec file for my custom inverter board. I am able to generate code for 3 Op Amps + 2 ADCs by using the "ThreeShunt_RawCurrents_Differential_InternalGain" option and STM32G474 as a temporary MCU before importing everything into a STM32G491 project.Additionally, do you have a specification for (differential) PGA shunt measurement network polarization offset and attenuation calculation, or do I have

Hello:I want use ST25R95 to do card emulation. But I can't find any source code in ST25 website.Can you help provide some source code?

Hello. I examined similar questions and answers. Since I'm a newbie, I couldn't find an answer to my problem.In the documentation of the STM32F756ZG development board, it is said that up to 24 channels of ADC measurements can be usable with 3 ADCs. When I want to assign pins in the CubeIDE, warning says that some pins cannot be used due to conflict.There are 2 different conflicts for ADC1, and only one for ADC3. I don't need to use ETH, but even if I set to ETH "disabled", the conflict does not disappear.I wonder if I can make 24 measurements with other available pins. Is it possible?Or does the dev card not allow using all the capabilities of the MCU?
