Hello everybody!I can't use USART2 in STM32G030K8 to transfer data.The TC flag of the ISR register is not set after writing data to the TDR register for an infinite time, if I use it to control the transfer of a byte, the program hangs without transferring anything.If I use the TXE bit of the ISR for control, then the data is transmitted partially, i.e. not every byte sent arrives.If I insert a forced delay after the byte is sent, then it doesn't solve the problem.USART1 works without problems.I am using the following USART initializationRCC-> APBENR1 | = RCC_APBENR1_USART2EN;USART2-> PRESC = USART_PRESC_PRESCALER_0;USART2-> BRR = 3333; //baud rate 9600USART2-> CR1 = USART_CR1_TE | USART_CR1_RE | USART_CR1_UE;for transfer datawhile(!(USART2->ISR & (1 << 7))); //wait set TXEUSART2->TDR = data; //while(!(USART2->ISR & (1 << 6))); // wait set TC (do not work)

I am using LIS3DH accelerometer. I would like to reset all register contents to power ON defaults through software method. I know that giving a power cycle would reset the contents of the registers to defaults, but I am looking for a SW method(like writing a bit in the register).

Hi,I am trying to figure out how to determine the reg=<0x??> value for the LIS2DW12. From the example page they have 0x6b but for a different device. I cannot figure out what this value needs to be.Thanks&i2c2 {       status = "ok";       #address-cells = <0x1>;       #size-cells = <0x0>;       lis2dw@6b {               compatible = "st,lis2dw12";               reg = <0x6b>;               interrupt-parent = <&gpio4>;               interrupts = <31 IRQ_TYPE_LEVEL_HIGH>;       }

Hi, Im searching for develop a NFC reader using the CR95HF IC transceiver, but i dont know if ST has a STM32 MCU firmware bridge to be programmed. The CR95HF should be connect to PC and the commands sent through the 95HF IC.I want to connect the CR95HF to PC and develop an APP to control the IC transceiver and read/write NFC tag IC ST25DV. So i need a firmware bridge to be programmed into a STM32 MCU. Maybe i will avoid develop the firmware.So, i have found the STSW-M24LR007 and the package contain a STM32F103 Firmware, but its an old develop, so i cant open with STM32CubeIDE. Do you know if this firmware has a earlier update or ST has other package to be used? Do you know if this firmware is a bridge?Maybe you could introduce other recent options.thanks,Best Regards,

In Table 150 ("STM32WLE5xx/55xx configuration in system memory boot mode") on page 380.In the section "USART2 bootloader", "USART1" must be replaced by " USART2".Thank you.JL

Hello!i am working with the STM32H745 dual core nucleo board.i have noticed that the app that i built runs perfectly when i debug it using IAR, on the other hand, it does not when i just connect the nucleo board to power and try to communicate with it.i tried to debug this using the LEDs on the board and found out that the last function to runis vTaskStartScheduler().what is the difference between running the app with debugging oposed to without it. please advise on how to debug this issue?thanks alot in advance

Hello,I'm working on an ultra low power application where the MLC of the LSM6DSO32X is used to wake up the mcu when interesting stuff is happening, in particular I implemented two decision trees, each one focused on the detection of a pattern.In order to reduce the false wakeups, I would like to apply the meta classifier only on one of the two trees, for the other one the counters are set to 0.Now the problem is that I don't understand how to do it with Unico. At some point of the MLC configuration in Unico, it ask for the end counter for the meta classifier (see attached image), however there is no way of configuring the sub-group of the meta classifier (I would like the counter to be 1 for the no_change result and 10 for the change result). It looks like Unico groups the DT result base on some internal rule that I cannot control.This is the meta classifier configuration in unico, I can only set the counter but I cannot configure the sub-groups. I would like to specify that the d

Hello everyone,I have Nucleo-L4P5ZG and the development environment is WIN10 , CubeIde1.4 and CubeMx 6.2.I am facing a strange behavior while I'm trying to debug a simple FREERTOS toggle Led code here are details:1- I started with Cube Mx and generated code for Cube IDE with the following configurations:Only GPIO Pin PB7 [LD2= Blue Led on Nucleo] configured as output Sysclk = 120 MHz drived by PLLCLK which is drived by MSI = 4MHzSelect FreeRtos Support without creating any OS resources except the Default taskSelect TIM7 as a systick timerand that's it.2- I put the toggle led code in the default task void StartDefaultTask(void *argument) { /* USER CODE BEGIN 5 */ /* Infinite loop */ for(;;) { osDelay(1000); HAL_GPIO_WritePin(GPIOB, LD2_Pin, GPIO_PIN_RESET); osDelay(1000); HAL_GPIO_WritePin(GPIOB, LD2_Pin, GPIO_PIN_SET); } /* USER CODE END 5 */ }3-Everything is working fine without launching the debug session4-When I started debug session the code stops at main function as expe

Dear Sir​・I want to use BLE with B-L4S5I-IOT01A.(FreeROTS)・However, "UM2178" and "Table 1. FreeRTOS ™ porting abstractions" say "not available".​​B-L4S5I-IOT01A cannot use BLE?​Can I use BLE if I create a project with CubeIDE and implement "STM32_BlueNRG1"?​Regards​​

Hey,I have both a NUCLEO-L432KC and a NUCLEO-F446RE. I'm using them to interface with an ili9163c based display. When I hook up the display to the L432KC it works great and I get a single image that fills the whole display. However, I'm trying to transfer the project over to a F446RE but when I run the program on the F446RE it only draws on the top half of the display and repeats the image i.e. if you were to divide the display into 4 quarters it is only drawing in the top two quarters and each of the top quarters are a repeat of the image I want to fill the whole display. I've tried using the same clock speeds on the F446RE as the L432KC just to see if it was something to do with timing but it doesn't appear to be the case. I suspect this has something to do with DMA because when I hook it up to a logic analyzer I can see the DMA signal (MOSI) has two repeating versions of the image. Any ideas why the DMA on one device would be behaving differently from the DMA on another?I am using D

Hi,I am using STM32H743ZI micro controller of LQFP144 package. My doubt is that in the data sheet they are mentioning that it has 2 direct channels for ADC but they are not mentioning what are the channels or pins offering thisThey are only talking about TFBGA240 +25 package pins offering this direct concept then what about LQFP-144 pins offering this.

Hi,I have a firmware doing permanent acquisition and processing of a signal coming from SPI on the M4 side - consider it an audio stream.On-demand I would like to save the processed buffer (say ~10 consecutive buffers once in a while, e.g. 1s every 10s) from the SRAM to a permanent file accessible from the A7 Linux userspace.What would be the best way to do this with the least impact on the M4 load ?My first guess was DMA from SRAM to DDR and then have Linux write from DDR to eMMC/SD but isn't there a more direct way ? Thanks a lotYann

Hello communityI face the following problemI have a global data structure which contains several member variables, I use this data structure to handle all my global variables needs across my project.Such datatype is delcared in "globals.h", and a variable using this datatype is declared in "globals.c" and exported as extern always in globals.h.I want to assign some of these variables when TouchGFX interactions happen (like moving a slider or pressing a button) in my TouchGFX "view"The problem is, if I include globals.h in my "view.cpp", then the TouchGFX simulator won't build as it cannot find "globals.h".for sake of simplicityglobals.htypedef _myType{ int sliderValue; }myType;   extern myType myGlobalVar;globals.c#include "globals.h"   myType myGlobalVar;How should I access my global variables then without breaking the interface simulator?Matteo

I am using STM32H747BI MCU and I have one project to write the data to flash memory. I am using core 7 to write the data to flash. While writing, I have to encrypt the data. So I requested cryptographic library software expansion from STM32 and they provided me the software. From that software, I copied four files:stm32h7xx_hal_cryp.cstm32h7xx_hal_cryp.hstm32h7xx_hal_cryp_ex.cstm32h7xx_hal_cryp_ex.hAfter that, I put these files in respective inc and src folders and I uncommented #define HAL_CRYP_MODULE_ENABLED  from stm32h7xx_hal_conf.h. After doing all of these, I started to encrypt the data but in the project it could not find CRYP_HandleTypeDef . It shows the error unknown type name 'CRYP_HandleTypeDef'. Could anybody suggest me what the problem is because I don't know how to solve this issue as I have done all the things that needs to be done.

Hello Community!I was using a system controlled with the STM32f105RC, I was able to program it with the ST-Link. In that system I got a problem so I had to change to another board with the same characteristics but, when I did so, I wasn't able to program any other system with that microcontroller.I used the ST-Link to program another system with a STM32f103 microcontroller an it worked, but with the board that I need to use It's simply not working.It's not only that board, I have another board with the same characteristics that I was able to program, but now I'm not able to program it any more. Any help will save me.Thanks!
