I'm trying to read a T2T tag with NFC card reader, Nucleo expasion board attached to STM32F103 Nucleo board. I'm using an example from X-CubeExpansion_NFC3This tag is well formatted with NDEF, but when I try to read with this example, I get an error in ndefPollerNdefDetect(). This funtion returns ERR_PROTO.If I read this tag with any other application, I can read it content.Can you help me with this problem. I'm sure, I'm doing something wrong, but I don't know what isThank you in advance, looking forward to hearing from youCarmen

Hi,how to differentiate both chips, if they have the same value for WHO_AM_I register?I know that I could read couple times the accelerometer values, calculate magnitude over all axis and check if the value is near 1g or 0.5g (assuming no movement during measurements), but this will not work if any HP is enabledIs there a simpler way?BR

I am looking for accelerometer ultra low noise with low g.I want to connect 4 sensors using I2C, so I need 2 pin SA0 and SA1.Do you have such sensors

Hi all,I am pretty new to the STM32 world and I have just started to play around with the STM32F429 discovery kit and STM32CubeIDE. I am OK with the basic & introductory projects, and I was able to have basic IO operations like LED blinking run properly. When I tried to first dig into the FreeRTOS concepts, I realized that I'm having issues with the osKernelStart() call taking place in "main.c". (If I comment out this line, the code builds and runs ok "enough" to blink LEDs.)To make sure that my own code is not affecting the behavior, 1) I started a clean STM32 project using STM32CubeIDE, 2) modified no config at all, 3) directly generated the code4) built the project5) started a debug session6) Debugged the code using "Step Over" When I hit the Step Over again when it's on the line where the osKernelStart() is being called, the debugging step options (Step Into, Step Over, Step Return) are all grayed out but the debug session seemed to continue working.To

Hi All,I want to use DMA to receive unknown length data. So I config USART_IT_IDLE and DMA_IT_TC and set DMA_BufferSize = 30 bytes. When the length of received data is less than 30 bytes, It works correctly and enters the USART1_IRQHandler(void) function. But the length of data is equal to 30 bytes, it enters the DMA1_Channel5_IRQHandler(void) function first then enters the USART1_IRQHandler(void) function again. Why does the length of data be equal to BufferSize cause Idle interruption?void RCC_Configuration(void) { RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_USART1 ,ENABLE); RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1,ENABLE); }   void GPIO_Configuration(void) { GPIO_InitTypeDef GPIO_InitStructure;   GPIO_DeInit(GPIOA); GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9; // TX GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_Init(GPIOA, &GPIO_InitStructure);   GPIO_InitStructure.GPIO_Pin = GP

Good morning,I've been fighting with an L496, trying to get it to jump into the bootloader.I'm using STM32CubeIDE 1.7.0 on a Nucleo-L496ZG.The code is based on a new project for the Nucleo board, hints from AN2606.Just to make sure that I wasn't too far off, I pulled out the "FLASH_JumpBootloader" sample program for the F769 and got it running on my F767 Nucleo, then pulled the important bits into a minimal test program. It works well, jumps right into the bootloader and I can attach to the board as a DFU.So I altered the start address for the L496 and the thing is fighting me. It just reboots the processor. I even tried it on a new L496 Nucleo, but it acts the same.Here's the code's important bits: /* USER CODE BEGIN WHILE */ while (1) { /* USER CODE END WHILE */   /* USER CODE BEGIN 3 */ typedef void (*pFunction)(void); pFunction Jump_To_Application; uint32_t JumpAddress;   if (HAL_GPIO_ReadPin(B1_GPIO_Port, B1_Pin) == GPIO_PIN_SET) {   JumpAddress = *(__IO u

Hi,I had a question regarding Bruno's excellent series on creating a simple bootloader.In part 3, there is an if statement which checks if something has in fact been loaded into the applications's flash region:// bootloader main.c if( ( *(uint32_t *) FLASH_APP_ADDR ) & 0x2FFE0000 ) == 0x20000000 ) { // jump to app main... }The logical AND operation against the dereferenced FLASH_APP_ADDR with a mask that I don't understand, should yield an initial SP.What does 0x2FFE0000 signify?Many thanks,Dan

Hello,I want to use the STM32L562QE-DK board to measure the current for my own developed PCBA. There is a connector CN20 that can be used for this purpose as written in the schematic for the board:Output connector to supply and measure external target:PIN 1: GNDPIN 2: Voltage source, current is not measured, it is not a copy of ourput voltagePIN 3: Output with current measurementPIN 4: Output voltage copy with 150R protection serial resistor, current is not measuredBut there is no voltage on Pin 3? And in the user manual for the board I also did not find anything.Where can I find documentation how to configure the board for this purpose?Thanks,Wolfgang

Hi,On the DK2 board, there is a LBEE5KL1DX-883 from Murata. But I want to use their LBEE5HY1MW (Type 1MW - LBEE5HY1MW | Wi-Fi® Modules / Wi-Fi® + Bluetooth® Modules | Murata Manufacturing Co., Ltd.) in my design. But on their site, they only mentions 'NXP I.MX Linux' . As ST has tried 1DX, will 1MW work on ST's Linux distribution? Furthermore, what about other WiFi modules on the market? Is it easy to run them with STM32MP15x?Thanks.

Hello,I tried to impelement a simple SPI Echo Slave.The Master transmits Data (Example for Nucleo 474RE - Master Full Duplex Interrupt) and the Slave waits for reception using HAL with a datasize of 1 Byte.After the Transfer is completed I am copying the received Byte into the Buffer for the next TX Byte and waiting for the next Transfer again.When receiving Data, every second Byte received gets dropped, and when trying to echo it, undefined data is sent.As seen in the Image, the first Channel is MOSI, the second Channel is CLK, the third Channel is MISO. The Slave should transmit the identical message sent by the Master, starting with the second Byte./* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * <h2><center>© Copyright (c) 2021 STMicroelectronics. * Al

Hello together,after a lot of trouble getting the USB HS port working on the STM32H747 on the STM32H747I-DISCO Discovery kit I’m stuck again. I’m using STM Cube IDE 1.7 and the HAL USB CDC lib.I was able to get USB CDC working on the M4 thanks to https://community.st.com/s/question/0D53W000002diUsSAI/stm32cubemx-h7x5h7x7-usb-cdc-bugOn the M7 core it kind of worked out of the box. But when I want to use it with the USB interal DMA enabled it didn’t work at all.I already figured out I have to disable the D-cache and not use the DTCM SRAM for the buffer: https://community.st.com/s/article/how-to-enable-dma-in-usb-with-stm32h7-devicesI provided a minimal example of code which already results in failure: ...   MX_GPIO_Init(); MX_USB_DEVICE_Init();   HAL_Delay(1000);   uint8_t buffer1[2000], buffer2[2000];   CDC_Transmit_HS(buffer1, 1468); HAL_Delay(50); CDC_Transmit_HS(buffer2, 4);   while (1) { /* USER CODE END WHILE */   /* USER CODE BEGIN 3 */ }W

As per the application note AN4967 Rev 7 AT+APPKEY command has been removed from the firmware of AT_SLAVE. I would like to know how can i set or enquire the APPKEY via AT Commands. Also is there possibility to set this key in firmware itself? Since as per the lora standard for OTAA activation, user should setup APPEUI, DEVEUI and APPKEY. But since command for AppKey removed so i wonder how can i set this key on module. Please update and share if there is any good reason to remove or the way to set the key in firmware itself.

Hello!I'm able to use the STLink V2 and output printf statements to the debug SWV ITM Data Console within the STM32CubeIDE.Is there a way I can access this data as it's coming in from another program? (e.g. a serial plotter).I want to be able to see sensor readings live as they're coming in from the chip.Thank you! :)

Hello,I'm working with the STM32L031K6T and I'm going to standby without RTC and waking up the MCU with the A0 or A2 without problems, but for the application I need to know which PWR_WAKEUP_PIN was used to wake it up. Its possible to get a flag after standby mode?  The signal used to wake up the MCU will remain a lot or time, so I can read it before the waking up, so maybe changing the configuration of the pins to normal GPIO? No idea how to solve it and I'm new in this kind of applications.
