Solved

Yesterday I was able to generate code normally using STM32CubeMX. But today I am generating code again using STM32CubeMX with a lot of undefined code. I sent the file to a friend and found that he generated the code once again using STM32CubeMX and it worked. But my computer still can't generate normal code again.

  Good morning,   I am working with the STM32MP1 and the STM32H7 and will make use of the SRAM memories for critical data. For my application and its security I need more information about the memories.   Is there any detailed description or analysis available for the SRAM memories intergrated in the MCU/MPUs of ST? Or the characterization of the memory?   Best regards, Andrés

Hello, I am testing the st25r95 with the X-nucleo-nfc03a1 attached to a nucleo-g0b1re, I am successfully running the democycle and reading nfc tags. In my application I have a limited amount of flash available (<20 Kb) and also,I only need to detect tags which have the ISO14443A (NFC-A) protocol. To reducethe amount of flash. One thing I have done (as suggested in another post “Howto minimize flash usage�?) is to set in platform.h -> RFAL FEATURESCONFIGURATION -> RFAL_FEATURE_NFCV to false. That indeed reduces the flashusage, but then the communication with the st25r95 stops.With all the functions enable:RFAL_FEATURE_NFCV to false:Only initialization.Can you give some advice about how to properly deactivate the protocols I don’t need?Thank you in advance.

Hello Community,when I enable the "Shared" option when connecting with STM32_Programmer_CLI.exe software, I notice that the serial number option ("sn=<>") is completely ignored. Is this a bug? The result is that wrong MCUs are flashed during a flash operation, although a serial number is passed.Used Command:STM32_Programmer_CLI.exe -c port=SWD shared SN=004000373039510634393838 freq=24000 -w $(BUILD_DIR)/$(TARGET).bin 0x08008000 -v mode=UR reset=HWrst

I'm not able to find a spec in the STM32F446 datasheet for minimum A/D input bias current. Does anyone know where I can find this info? I need to sample the voltage from a high resistance potentiometer and it would be handy to know if I need to buffer prior to connecting to A/D pin. Thanks!

trying to avoid through hole part, would prefer a SMD part.

I am trying to implement output capture using the LL APIs but cannot get it to blink the LED every one second on the NUCLEO board, however, I cannot get it to blink at all. Is there a register I missed?Here is my code:#include "stm32c0xx_ll_bus.h"#include "stm32c0xx_ll_gpio.h"#include "stm32c0xx_ll_tim.h"/*---------------------------------------------------------------------------------------------------------------------------------------------------*/void LED_PA5_init(void){   LL_IOP_GRP1_EnableClock (LL_IOP_GRP1_PERIPH_GPIOA); //for LED PA5   LL_GPIO_SetPinMode (GPIOA, LL_GPIO_PIN_5, LL_GPIO_MODE_ALTERNATE);   LL_GPIO_SetAFPin_0_7 (GPIOA, LL_GPIO_PIN_5, LL_GPIO_AF_5); //AF5 is TIM1_CH1 for PA5}void Timer1_1Hz_OC_init(void) //1 Hz = 1 cycle/s = 1 s delay{   LL_APB2_GRP1_EnableClock (LL_APB2_GRP1_PERIPH_TIM1);   LL_TIM_SetPrescaler (TIM1, 1200-1); //12000000/1200 = 10000 Hz   LL_TIM_OC_SetMode (T

I want to use MX25UM51345G on STM32L5. When configuring the Memory type, I found these two mode:001: Macronix mode, D1/D0 ordering in DTR 8-data-bit mode. Regular-command protocol insingle-, dual-, quad- and octal-SPI modes.011: Macronix RAM mode, D1/D0 ordering in DTR 8-data-bit mode. Regular-commandprotocol in single-, dual-, quad- and octal-SPI modes with dedicated address mapping.But I didn;'t found any detials about the difference between these two mode. So what is "dedicated address mapping" means? Is there any example about how to use these two mode? What kind of memory should use Macronix RAM mode?

Hello,I am working with the Nucleo Bluetooth boards (NUCLEO-F401RE + NUCLEO-IDB05A2) and I want to test some custom code I'm writing to make sure I understand how to use the X-CUBE-BLE software package. To do this, I am trying to use the ST BLE Toolbox to send a command to the Nucleo boards to turn an LED on/off. The problem is that I can't find anywhere to write anything custom on the phone. I feel like I'm missing something very obvious, but I can't find any documentation on the ST BLE Toolbox app at all.The app does detect the device and can connect to it, but I can't find out how to add any custom functionality to the app.Does anyone have either:1) Instructions on how to set up custom commands in the ST BLE Toolbox2) An easier method to test custom code with a phone?

Hi im using the ST25R3911b and the RFAL lib.With what expression can i see the Data on my Tag ?

I'm attempting to do a simple Input Capture using Timer1. I thought as a start I would generate a single 200uS pulse using a Signal Generator and use Timer1 to detect it. I can't seem to get the capture to work no matter what I do.I tried using HAL and examples from Web...No luck.I tried examples from a book I have and from the Reference Manual...No luck. Here is the code I'm currently using;// TIM1 clock enable RCC->APBENR2 |= (1 << 11);   // Configure PA8 as alt func TIM1 CH1 RCC->IOPENR = 1; GPIOA->MODER &= ~(3 << 16); GPIOA->MODER |= (2 << 16); GPIOA->AFR[1] &= ~(0x0f); GPIOA->AFR[1] |= 2;   // TI1 as input TIM1->CCMR1 |= 0x41; TIM1->SMCR |= (5 << 4) | 4; // CC1E Enable output TIM1->CCER |= 0x0b;   TIM1->CR1 |= 1;   while (1) { while(!(TIM1->SR & TIM_SR_CC1IF)){}   // Reset the Update Interrupt Flag TIM1->SR &= ~TIM_SR_UIF; }

When I use DFSDM, I configure FOSR= 256 ISOR=1 and the output is outside the range in the reference guide +-16777216

X-CUBE-EEPROM v5.0.0 includes a sample for NUCLEO-STM32L552ZE-Q.I am trying to use this sample for STM32552CCT6 to run EEPROM Emulation, but the EE_Init() execution results in an error.To begin with, is it possible to operate EEPROM_Emulation with STM32L552CCT6?

Regarding P/N: STM32WB55 in a WLCSP100 package:Q1: When VBAT is not in use, can I connect it to GND?Q2: When VDDA is not in use, it must be connected to VDD, but is it still requires a 10 nF + 1 μF capacitors?Q3: If VDDA is not in use, can I connect VREF+ to GND?Thanks!Nir

I've just downloaded 2.13 but I am unable to find release notes for it looks like these were not updated yet?My real question is if Internal ticket number: 144023 was addressed within that release

I used the ST25R3911-DISCO Board GUI and C++ DLL demo to utilized the ISO-DEP function to read from and write to an NFC-B card. How do I go about doing this with the X-nucleo-NFC05A1 on Nucleo 64 using arduino IDE? I need help getting started on writing a function to poll, select card, read and write to that card. Thanks,-E.

I am new to TouchGFX, I ran into a problem that using TouchGFX 4.21.1 on STM32H743Eval 2 , I add a global variable (e.g. counter) within "USER CODE BEGIN 0", , in StartDefaultTask, add counter++ in the main.c file, follow MVP design procedure, just want to dispaly counter value in TextTArea widget, CubeIDE code compiling is ok, but when click "run simulator", it appers "C:\TouchGFXProjects\STM32H743\TouchGFX/gui/src/model/Model.cpp:13: undefined reference to `counter'I am also using 4.18.0 of touchgfx, both have same symptom, is there any setting I missed, please help, thanks in advance.

Hello,I'm using the ADC on a STM32G431 to read 5 voltages at 20kHz. Everything works well, but suddenly the 5 channels "get stuck" or freeze, i.e. the value they measure becomes constant even though the voltages on the input pins still fluctuate. Sometimes the measured values resume to being correct again by themselves after a little while (like after 200 samples for instance), other times the values remain constant until I manually cycle the MCU power.Some more details about the code architecture:I use 5 channels of the ADC2 in single-ended modeThe sequence of 5 regular conversions (Single conversion mode) is triggered by TIM2's TRGO (update event at 20kHz)Data is stored in an array by DMA in circular mode. In the DMA ISR I have code to copy and log this data (at each DMA transfer complete interrupt).Some info about my debugging so far:I've enabled ADC overrun interrupt and checked that it never gets firedSame goes for the DMA transfer errorWhen logging the data I also log a
