I cannot find the logic in the schematics about the mapping of the 2 stmod+ connectors.Which pins of the stmod+ correspond to the MCU pins ?Page 7 of the schematic folio is very confusing.I just found pin 3 & 4 of the stmod+2 to be mapped to PG10 & PG9

I'm considering a ST25R3916B design to emulate a 14443 A&B device and preferably be powered by the field. It's not at all clear from the datasheet what the current draw is when not operating in an Active mode - there's a big gap between 4uA in Initial NFC Target mode and 4mA in Ready mode. It's hard to believe that the device can do all its frame decoding and passive modulation on 4uA.

Hello!I am trying to write the memory of a ST25DV64K-I with an EFR32MG13.I created a wrapper on top of the I2C driver of this micro-controller.I can send read and write command with no error. But the write command is not working.For example, I set 4 bytes starting at the address 0x0000 to 0x01 using the RF interface. When I reading it though I2C I can see the value is 0x01. It is good.Then, when I am trying to change the value to 0xFF with a I2C write command, it is changed to 0x00 instead of 0xFF. I triple checked the sent buffer contains 0xFF not 0x00. I tried with other value (0x05) but the tag always ends up setting the memory to 0x00.If I am trying the set only one byte at specific address it is working but it always set the memory to 0x00.I cannot find why. Can you help me understand this behavior?Thanks a lot.

STM32F407 Discoveryen.MB997-F407VGT6-C01_Schematic.pdfHSE quartz 8 megahertz.How are 4-26 MHz generated for HSE?With an oscilloscope, I see only 8 megahertz on X2 quartz.Where are those 25 megahertz that are listed as input for HSE?In the documentation I read this:This frequency cannot be changed, it is fixed at 8 MHz and connected to PH0-OSC_IN of the STM32F407VG.But in Cube Mx this frequency can be changed from 4 to 26 megahertz.

Hi,I have an issue, I can't change the project in STM32CubeMX. I wrote the project name V04 at the beginning of the project now I would like to change how can I do it. I don't touch even the textbox.Thank you

Hello,We are struggling with the configuration of LwIP for my STM board over FreeRTOS.We have our own designed board with STM32F777ZIT controller.Ethernet and LWIP is working as expected as we used without FreeRTOS middleware but we are not able to integrate ethernet with FreeRTOS in STM.I have attached cumbemx screenshot for ethernet connection to STM.Also find attached ETH and LWIP settings in cubemx.We are executing following steps to access FreeRTOS and ethernet.1.In cubeMX enable ETH in RMII mode set PHY Address as 0 in parameter Setting.2.Enable LWIP in middleware.set DHCP as enabled (tried it with DHCP disable also)3.Enable FreeRTOS in CMSIS_V1 mode all other settings in RTOS are as it is.Then we have generated code and build it...It can build successfully, but does not run as it throws DMA memory errors.Laptop settings are correct as I can ping board if RTOS is not used.I would appreciate if you could provide me some step by step, in addition with a reference.

My development environment is stm32cubeMX and IAR.​​First of all, the configuration I programmed is like this.1. Init (write Status Register WP-E set 1)2. Block Erase (to the address where i will store the data)3. Write data to buffer4. Program Execute5. Load data (load data in physical memory page to data buffer)6. Read data​​If Delay is not used between 2 and 5, HAL_QSPI_Command_IT function is passed to Error_Handler.I want to make it work without this delay.If a delay is inserted or executed line by line, it operates normally without going over to Error_Handler.​Are QSPI commands not usable consecutively?​void Flash_Init(void){ sCommand.InstructionMode  = QSPI_INSTRUCTION_1_LINE; sCommand.AddressSize    = QSPI_ADDRESS_24_BITS; sCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE; sCommand.DdrMode      = QSPI_DDR_MODE_DISABLE; sCommand.SIOOMode     = QSPI_SIOO_INST_EVE

I'm trying to receive more than 1 byte but it receive only 1 byte. Poll method or IT, it doesn't matter. Always receives 1 byte and writes it in rx_buffer[0]. When I search it I found out the reason is timeout, I increase timeout 1000 from 100ms but nothing changes. Can anyone help me please? Here is my code for poll/* Includes ------------------------------------------------------------------*/#include "main.h"#include "string.h"/* Private variables ---------------------------------------------------------*/UART_HandleTypeDef huart1;UART_HandleTypeDef huart6;DMA_HandleTypeDef hdma_usart1_rx;/* Private function prototypes -----------------------------------------------*/void SystemClock_Config(void);static void MX_GPIO_Init(void);static void MX_DMA_Init(void);static void MX_USART1_UART_Init(void);static void MX_USART6_UART_Init(void);USER CODE END PFP *//* Private user code ---------------------------------------------------------*//* USER CODE BEGIN 0 */char rx_buffer[50];char tx

Hello,I use STM32F429 Discovery board, which has touch controller,but in my project I don't need it, so I want to turn it off.In BoardConfiguration.cpp I found this initialization:STM32F4TouchController tc; HAL& hal = touchgfx_generic_init<STM32F4HAL>(dma, display, tc, dispWidth, dispHeight,(uint16_t*) 0, 0, 0);And description of touchgfx_generic_init function says:@param [in] tc Reference to the touch controller driver (or NoTouchController to disable touch input).How to turn Touch controller off?Should I change "tc" in touchgfx_generic_init for NoTouchController or what?Thank you,Anton

Hi all,When writing tests for handling single and double errors on the STM32H753/43/42/50, there doesn’t appear to be a way to turn off the ECC or access the parity bits to force single or double errors.  Relying on them occurring randomly isn't great and I'd really like to be able to inject known errors at known locations. Flash memory can be tested by judicious overwriting of codewords to manipulate the parity symbols but that technique won’t work on SRAM.Section 2.5 of AN5342 mentions there may be routines available (which would be great to have) but I can’t find other reference to how this might be done - even if via DAP.

Hello,I am using the STM32WB55CEU6 chip and while trying to check the functionality with the STM32CubeMonitor-RF I am getting the following error: "Device under test not responding COM port closed"Upgraded "stm32wb5x_BLE_Stack_full_extended_fw.bin" and "P-NUCLEO-WB55.Nucleo -> BLE_TransparentMode"Normal operation was confirmed when the P-NUCLEO-WB55 board was powered up using the same procedure.Please advise if the procedure is wrong

I am trying to write a code so that I measure temperature and humidity via HTU21D sensor. It uses I2C interface. In the datasheet:The HTU21D(F) sensor requires a voltage supply between 1.5V and 3.6V. After power up, the device needs at most 15ms while SCK is high for reaching idle state (sleep mode), i.e to be ready accepting commands from the MCU. No command should be sent before that time. Soft reset is recommended at start.According to this information, I formed the following function:void HTU21D_SensorInit(void) { uint8_t pData[] = {0xFE}; // SOFT_RESET if(HAL_I2C_Mem_Write(&hi2c2, (DEVICE_ADDRESS << 1), WRITE_REGISTER, 1, pData, 1, HAL_MAX_DELAY) != HAL_OK) { Error_Handler(); } // HAL_UART_Transmit(&huart1, (uint8_t*)"Sensor initialized!\r\n", 21, 100); for debugging HAL_Delay(15); }And I invoke this function in main after MX_I2C2 is called.This function works find and doesn't go into Error_Handler. In while(1) part of the main function, I invoke the following

I'm looking for the MT25TL01G_STM32H750B-DISCO.stldr external loader source code. The github (STMicroelectronics/stm32-external-loader/tree/main/STM32H7x_boards) is missing this one.

 There's no such register in LPUART.Seen also in RM0394, maybe will present in other RMs of that era, too.JW

I've got the STM32MP135F-DK Discovery kit yesterday; and am going stuck on setting up and using the contributed microSD. Demonstartions are not starting.My Steps so far:- STLink software is installed (WIndows10 pro). - the supplied microSD ist installed in Discovery Kit- Power is supplied to USB-C- Boot switches are set as described in Table 5 of the UM, Boot from SD card on SDMMC1.  (pg.13, Table 5, Boot0: 1 / Boot1: 0 / Boot2: 1 )What going on on Display: - Screen1: "ST live.augmented"; dark, then ..- Screen2: left side "ST32 MP1" & Linux symbol ..- then display is going dark, no more responses. Reading the supplied microSD with Windows 10 only shows many empty drive letters.(I did not format the µSD, as Windows ist suggesting)My questions:1. which demonstration should I see from the base demonstration? (there are no examples at the UM)2. what steps are required to start the demonstrations?3. how is it possible to check the contents o

I purchased a STM32F429 Discovery Board about a year ago. I finally got around to unboxing it today. I want to see if I can figure out how to use the TouchGFX tool with this board. I want to have 6 buttons and a textbox on the display.The board has a program loaded on it from the factory. Apparently something is not right with the software. The screen has Video player, Image browser, Clock/Calendar, Performance, Game, and System Info images on the screen. I assume you are supposed to touch these to see a demonstration of these items.However, none of them work properly. If I touch Clock/Calendar the display will sometimes pull the calendar and clock up. At other times the screen changes to "MJPEG Player". If I touch the System Info "button" it pulls up Image Browser and says "No File Found". Regardless of what comes up, NONE of the buttons respond to being touched. The only thing I can do is press the reset button. This restarts the board and it returns to the default startup screen.Did

Hi there,I am using a Nucleo H723ZG and my ADC(s) behave weirdly.I need only one ADC, from the datasheet the ADC3 supports 5 MSPS.Since I needed the highest possible sampling rate, I've chosen this one.The data gets collected in one burst of 4096 12-bit samples into a DMA buffer of 16-bit words.On the input I attached a potentiometers wiper for testing, the other ports of the potentiometer are connected to AGND and AVDD on the Nucleo board.Since I've got weird output values, I dumped the first 200 words of the buffer into logs, the logs are attached to this post.The first burst of 4096 samples (adc_3_12_bit_buffer_1st_run.log) shows the expected value (4095) in each sample (except for the first 8), since the potentiometer was set to the full voltage of roughly 3.3V.But without changing anything, the second and following bursts (adc_3_12_bit_buffer_2nd_and_later_runs.log from the 2nd, but the others are similar) show completely different values, where all N samples the values are as exp

Hi,im trying to get this example to work, but it sont compile. The paths for all includes are set up with a link folder in the project.I double checked those, but cant get to the problem.The order is: "main.c -> main.h -> stm32f3xx_hal.h -> HAL_StatusTypeDef HAL_Init(void)" and the file is in "\Drivers\STM32F3xx_HAL_Driver\Inc\stm32f3xx_hal.h" as link in the project and set up as include path (see pictures).Something looks strange, as there are no files shown in "../Core/inc" in picture "strange.jpg".Its Cubde IDE Version: 1.12.0.

I am looking for a full datasheet for ST microcontroller 324BAAP 269-546 9911L V5 MYS 145. Do you know if I can find anywhere or is any way to ask ST to provide this? Thanks in advance for any help.Zygi

I need to fix an audio amplifier that uses a TDA7266M. Unfortunately, I can only find TDA7266 (stereo version) in stores in my city. I compared the pins and it seems that I can use one channel without any modifications. What should I do with a disconnected channel? Is it enough to connect the input via a capacitor to ground?
