The chip type I am using is st25r3915. After I port RFAL, when I use "ST25R_SELFTEST" in "ST25NFC_EMBEDDED_LIB_ST25R3911B_1.4_0", the result of "Check IRQ Handling" is "ERR_TIMEOUT", what is the possible reason?

Hi,I have bought an STM32F429I-DISC1 discovery board to learn STM32 and STM32Cube. When I try to debug my project, I always get "No ST-LINK detected! Please connect ST-LINK and restart the debug session". I have tried various solutions I found online like installing the latest driver and even the solution presented at ST community question "No ST-LINK detected! - STM32CubeIDE 1.6.1 - Win7 [SOLVED!] CubeProgrammer can see and program the board fine, CubeIDE won’t see the ST-LINK probe." but nothing works. Can anybody help?

I have a Timekeeper M48T08-150PC1 and need to know the year of manufacture.How do you read de manufacturing date codes and Battery trace codes after 2010?My Chip traceability marking: "MYS 99 419 E" .Battery Trace Code: "W1454X"

Hello,I'm using an ST32U5 microcontroller and I'd like to ask some question about the ADC linear and offset calibration feature.1 - This feature is only available on ADC1 or is it also available on ADC4?2 - Right now at startup I'm launching the ADC1 calibration with the following parameter :ADC_CALIB_OFFSET_LINEARITY. Does this calibrate both the offset and the gain?3 - Is there some issues (except for a longer startup time) in launching the calibration every time at startup?Thank youMatteo

What is the correct procedure to open an STM32 project from one of ST’s sample/example projects ? I’ve downloaded the STM32 Cube H7 example folders and I think the NUCLEO-H743ZI folder is most relevant (I’m using the H743 micro for this project at work), and from there there are a multitude of examples under various folders such as UART. I could choose, for example, the UART_TwoBoards_ComIT folder in which we see the following structure: From this point what is the correct procedure that takes this example project into STM32CubeIDE (I’m running version 1.10.1), please ? The EWARM folder does include project files none of which load the project into the IDE.Thanks.

I have tried Timer 2 CH1, and Timer 3 CH1. No Luck.I know the pin has a square wave going into it and the timer is counting, because I can poll GPIOB->IDR and read TIM3->CNT.Nothing I can do can get a reading other then zero from TIM3->CC1I cannot get a IRQ from TIM3 unless I force it via TIM3->EGR |= 2;My Init Code:-void InitTimer3(void){ GPIOB->PUPDR &= ~(3<<8); // No Pullup or Pulldown GPIOB->OSPEEDR |= (3<<8); // Very High speed GPIOB->MODER &= ~(3<<8); // PB4 Input GPIOB->AFR[0] &= ~(0x0F << 16); GPIOB->AFR[0] |= (2<<16); // AF2 RCC->APB1ENR |= 2; // Timer 3 enable RCC->AHB1ENR |= 2; // PORTB Clock Enable TIM3->CCER = 0; TIM3->PSC = 511; // Prescale TIM3->ARR = 0xFFFF;//250; // Max Count TIM3->CCMR1 = 1; // Compare 1 TIM3->DIER = (1<<1) | 1; // CC1 IRQ enabled TIM3->CR1 = (1<<7) | 1; // Enabled, UP, Auto Reload Buffered TIM3->CR2 = 0; TI

When I created the TouchGFX project, I set it up to 800 *480.However, the LCD has been changed, so we have to change the things we have worked on so far to 854*480.I am trying to change the resolution in TouchGFX, but the setting part is not allowed to be modified.We need to change 800*480 to 854*480. If anyone knows how to do it, please ask

I wanted to use STM32CubeIDE with the NUCLEO-H753ZI and to my surprise there are no examples in the list to pick from. I there a !:1 compatible board? I was able to make my own example but would like to see some ST demo solutions.

Hello together,I'm using Nucleo-32 board (with a STM32G431KBTx) and have got some problems...In my project I'm using:-> UART (here I'm using RX-DMA and interrupt with an IDLE-flag)-> ADC, one channel-> I²C with an EEPROM (no DMA, no Interrupt)Problems and attempted solutionsProblem 1: if I write some bytes to EEPROM (I'm using HAL_I2C_Mem_Write(...) for that), and wait 5ms after the writing a page, the MCU stucks in HAL_Delay forever. After some googling I found a solution for this, increase interrupt priority for SysTick_Handler. Okay, all my interrupts have 0 as "preemption priority", so I've configured priorities like this:After that fix, reading/writing from/to EEPROM runs like a charm.BUT:The uart communication broke. That means, I request some data (exactly 70 Bytes) from MCU by sending a character (i.e. an V), but I get just 65 bytes, or 67 bytes, or 70 bytes, or 64 bytes... so it's not deterministic, but in 98% the requests I get less then 70bytes...If I set all the pr

Hi all,I have a project running on an STM32F427VI that makes some specific use of the dual-bank flash, both for storing certain configuration parameters and for a custom bootloader. It's great, but I don't get anywhere near using the full 2MB of flash memory, so given difficulties in finding chips I'd like to be able to use the STM32F427VG chip, with 1MB of flash, instead.I see that if the DB1M option bit is set, I can use the flash of the 1MB chip in dual-bank mode with a layout similar to the 2MB chip, which is perfect.So I got a 1MB chip and soldered it to the board. For fun, I programmed it with my existing bootloader and application and ... it worked?This is surprising, because the bootloader process uses flash that is beyond the 0x0810 0000 (1MB) boundary. If I connect to the chip using ST-LINK, it correctly shows the 1MB flash size, and if I go to "Erase Sectors ..." it correctly shows the 1MB single-bank flash layout. But in my code, at various times I erase flash sectors >

We will be using this part to drive 6 automotive contactors. Supply voltage is 12/24V.

I'm trying to run a 4-stage dc-dc converter using the NUCLEO-G474 board.For this, the MCU needs to execute 4 parallel controllers at 200 KHz. I am aware of how to set up a single filter/controller by looking at AN5305 application note, but is there some way of setting the FMAC with 4 filters simultaneously? (assuming those filters have 4 feedforward taps and 3 feedback taps each)

I want to reduce the output voltage of the GPIO pin by programming. So, I'm finding a way to reduce core voltage.Is it possible? then where can I do it?If not, is the only way to change fixed LDO physically?For example, using 2.0 V-output LDO.

Absolute Newbie here trying to do my first project. I haven't figured out how one gets to write their code and where. I take it we are to use Keil for that part and I do have it installed from other uC work a couple of years ago. Was this supposed to be added to some sort of toolchain during software installation so that it pops up automatically after Code Generation is executed ? If so, can I add it now ? Thanks.

Hello,I have just "finished" the ethernet interface for a STM32F7, now we think about also using the USB high speed interface (yes, it needs an external high speed USB PHY), that would be for data streaming, as an alternative for using ethernet, as many laptops these days don't have a direct ethernet connection, even less so with PoE.We need an ultra-reliable connection, running for hours / days / weeks, probably as a "mass storage" device (which uses USB bulk transfers, we prefer this compared to isochronous audio class for several reasons).Data rate will be about 50 Mbit/s max.Can anybody please report about their experience with similar use cases with the F7?Thanks!Edit:I almost forgot - how's the (windows) driver side handled by ST / with ST devices?In an old product we use a Cypress FX2 chip plus its win driver.

Hello community,now that STM32F767 + lwIP / TCP is working well, I found that sometimes it takes too long for streaming that the other side gets the data (some other network traffic, or delayed ACKs, or whatever Windows does), and the STM32's internal SRAM buffers are not big enough.Right now I'm using about 350 kB, but at the highest streaming rate of about 50 Mbit/s, that is enough for only about 50 ms.So now I'm looking for some small package external SRAM.The problem I see:size / serial vs. data rateWhen using external SRAM as kind of FIFO, it needs at least double data rate of the 50 Mbit/s = ~7 MByte/s, in case of a serial solution even much more for addressing.For now I have only experience with parallel SRAM (connected to an FPGA), so I'm looking for some advice!My best guess for now would be to look at QSPI, or OctoSPI, and I'd rather have some input from people who already used this and have some experience concerning handling and throughput.

I have used MX up to this point to configure my peripherals. Even though I've manually configured these for most of my career, I'd prefer to keep using MX for this project since it's been successful up to this point. For some reason it doesn't show me the baud rate for SPI2 like it does for SPI3, however (even though it's greyed out due to being constrained). Is this just a bug, or would I discover something specific to SPI2 that's a problem if I try to configure it manually?
