I want to understand the Timeout parameter of the HAL_SPI_Transmit, HAL_SPI_Receive and HAL_SPI_TransmitReceive function.

I'm attempting to enable the Stop mode on the STM32L4R5ZIP, but it appears to significantly deviate from the specifications outlined in the datasheet, exhibiting a higher current consumption ranging from 7 to 9 mA in both sleep and stop modes.Even after setting all free pins to default mode, deactivating all GPIOs, the power consumption remains consistent. I have experimented with both FreeRTOS and a non-FreeRTOS project, yet I consistently observe a 7mA current consumption in STOP Low-Power modes.In the FreeRTOS project, I implemented tickless mode with the following code snippet:void PreSleepProcessing(uint32_t ulExpectedIdleTime){/* Called by the kernel before it places the MCU into a sleep mode because  configPRE_SLEEP_PROCESSING() is #defined to PreSleepProcessing().   NOTE:  Additional actions can be taken here to get the power consumption

I cant make work the HRTIM. I am using the weact board.I tried HRTIM-A and TRTIM-D using the cubeide (latest updated). the first one using "basic HAL" and the second using "Advanced Hal" instructionsTIM5 works so it seems that clock is working.I added following code to make run the timers and the debugger passed them without trouble: MX_HRTIM_Init(); if( HAL_HRTIM_WaveformOutputStart(&hhrtim, HRTIM_OUTPUT_TD1)!= HAL_OK) { Error_Handler(); } if (HAL_HRTIM_WaveformOutputStart(&hhrtim, HRTIM_OUTPUT_TD2)!= HAL_OK) { Error_Handler(); } if (HAL_HRTIM_WaveformCountStart_IT(&hhrtim, HRTIM_TIMERID_TIMER_D)!= HAL_OK) { Error_Handler(); } if (HAL_HRTIM_WaveformCounterStart(&hhrtim, HRTIM_TIMERID_TIMER_D)!= HAL_OK) { Error_Handler(); } if ( HAL_HRTIM_WaveformSetOutputLevel(&hhrtim, HRTIM_TIMERINDEX_TIMER_D, HRTIM_OUTPUT_TD1, HRTIM_OUTPUTLEVEL_ACTIVE)!=HAL_OK) { Error_Handler();

I have an STM32G071CBTx with a rotary encoder wired to GPIO pins PB5 + PB7 (LPTIM1_IN1 and LPTIM1_IN2), but for some reason it will never count down no matter which way the encoder is turned.I have checked the encoder waveforms and they are as expected, and it's not just "rattling" with one input stuck low or high as I can make the counter run through the full count range by turning the encoder.Initialisation code (LL) looks like this:void MX_LPTIM1_Init(void) { /* USER CODE BEGIN LPTIM1_Init 0 */ /* USER CODE END LPTIM1_Init 0 */ LL_GPIO_InitTypeDef GPIO_InitStruct = {0}; LL_RCC_SetLPTIMClockSource(LL_RCC_LPTIM1_CLKSOURCE_PCLK1); /* Peripheral clock enable */ LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_LPTIM1); LL_IOP_GRP1_EnableClock(LL_IOP_GRP1_PERIPH_GPIOB); /**LPTIM1 GPIO Configuration PB5 ------> LPTIM1_IN1 PB7 ------> LPTIM1_IN2 */ GPIO_InitStruct.Pin = ENC1_As_Pin; GPIO_InitStruct.Mode

Good morning community,I am trying to capture output compare unit.Board: STM32F407G Discovery.I configure TIM1 which is 16bit timer on bus1.Reference clock is 12.5Mhz in our case.I am seeing when I run the code only one time interrupt is generated and after that it will not toggle the LED Gpio.So, my concern is that it needs to toggle every time when interrupt is generated by comparing that.The code is here,In main function code is here:         while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ if(HAL_TIM_OC_Start(&htim1, TIM_CHANNEL_1) == HAL_OK) { HAL_GPIO_TogglePin(LD3_GPIO_Port, LD3_Pin); HAL_Delay(1000); } if(HAL_TIM_OC_Start(&htim1, TIM_CHANNEL_2) == HAL_OK) { HAL_GPIO_TogglePin(LD4_GPIO_Port, LD4_Pin); H

Hello to all, Our design is using STM32F042G6 MCU to implement STSW-STM32011 firmware interface based on STM32Cube which implements ISO7816 protocol for us to talk to smart card. Unfortunately it does not seem to move beyond ATR.Is our MCU we use not good enough to support this FW, can it support only T=0 without T=1? If not good enough, what is the minimal MCU that would support the above FW or similar for ISO7816 over USART?Thanks for your help, Peter

Hi,I have successfully setup SPI between a master to many slave STM32F373s.  I include an 8 bit deviceID in the packet header and the master always initiates the request.I am looking for the best way for the master to assign unique device IDs.  I'm considering adding jumpers or switches to set the device ID in hardware.  In this case I would have the master discover devices by sending requests starting with device ID 1 and incrementing device ID until there is no response/timeout.  I"m leaning towards this solution since it allows the user to keep devices in the same order after a reboot or if the modules are swapped out.  It also allows the ID to be retained.  I'm considering having the master broadcast to all devices, and have each slave device wait for a random period before accepting requests from the master.  The master would continue to accept requests until a timeout is reached. I

Hey STM32 Community, I'm currently working on a project involving the STM32L072CZ microcontroller and could use some guidance on CRC calculation procedures. Here's a rundown of what I'm trying to accomplish: I'm downloading a FOTA .bin file in 1024-byte chunks, totaling 60kb. These chunks are stored in a data buffer, and my task is to calculate the CRC of the entire file for verification purposes. Here's the approach I've taken so far:For each incoming chunk of data, I'm accumulating its CRC using the function: chunkDataCrcValue = HAL_CRC_Accumulate(&hcrc, (uint32_t*)dataBuffer, BUFFER_SIZE);Once all data chunks are downloaded and their CRCs accumulated, I calculate the final

Hello everyone, I am currently working on the SMT32H747i_DISCO board and I was wondering if it is possible to use the Segger J-Link debugger on the Board. There is a j-tag pin out connected to the Dev board which suggests that it should be possible. I didn't have any luck so far. Are there additional ports necessary? Am I missing something. I can't find any documentation to the purpose of the connection. Thanks for any help. Regards Maikel

Hi Team,      We are using the STM32F103RDT6 microcontroller in one of our projects. The end-user application of our project is a laptop vending machine. Simply put, students can acquire laptops/tablets by using their IDs. However, we are facing difficulties in verifying whether the laptops/tablets returned by the students are the same devices they took. All of the devices are Type-C only.Therefore, we are planning to automatically read the Vendor ID (VID) and Product ID (PID) of the devices (laptops/tablets) using the STM32 microcontroller. Can you suggest or help us with the procedure to make this happen? Is it possible to read the Product ID using STM32?

Hello, i'm testing FDCAN in my stm32g431 and it doesn't work well. Messeges goes throught it, even if ID doesn't match (TxHeader.Identifier = 0x102 shouldn't pass, but it does!) static void MX_FDCAN1_Init(void){hfdcan1.Instance = FDCAN1;hfdcan1.Init.ClockDivider = FDCAN_CLOCK_DIV1;hfdcan1.Init.FrameFormat = FDCAN_FRAME_CLASSIC;hfdcan1.Init.Mode = FDCAN_MODE_EXTERNAL_LOOPBACK;hfdcan1.Init.AutoRetransmission = DISABLE;hfdcan1.Init.TransmitPause

Hello STM Community,We are currently engaged in the development of a Battery Management System (BMS) and have chosen the Texas Instruments Bq79652 Q1 IC for sensing voltage, current, and balancing cell voltages. This IC communicates via UART from the host to the device (IC). For testing purposes, we've opted for the STM32F103C8T6 MCU.As we look ahead to ensure the optimal performance and efficiency of our BMS, we seek guidance on selecting the most suitable MCU for our future endeavors. Our criteria include:1. **Performance:** We aim for a MCU with robust performance capabilities that can handle the intricate demands of BMS operations efficiently.2. **Integration:** Integration capabilities are crucial for seamless incorporation of additional algorithms such as State of Charge (SoC), State of Health (SoH), monitoring functions, and protective measures.3. **Compatibility:** We require an MCU that is compatible with the communication protocol an

The CAN connector on the board uses FDCAN1 on PA11, PA12 with PH8 being used to control the standby mode of the transceiver.To get the CAN interface working on the STM32H7B3I-DK I need to:Ensure that the STMOD+ connector is not used.Open SB22 and SB24 to disconnect PA11 and PA12 from the WiFi.Close SB3, SB4 and SB5 to connect PA11, PA12 and PH8 to the CAN transceiver (these took some finding as they are under the LCD and are not shown on the schematic - possibly because the latest available for download is MB1332-H7B3I-C01, but the board is MB1332-H7B3I-C02).Is it still possible to use the WiFi module?The user manual (UM2569) states "The module uses the SPI interface, as the corresponding firmware (for SPI capability only) is downloaded on the ISM43340-M4GL44-10CF Wi‐Fi® module", but the WiFi Solder bridge configuration tab

Bored Saturday, I was just curious who's using which RTOS:FreeRTOS (Hideous Hungarian HorroRTOS, where code is fugly and deficiencies are touted as features ;)Azure/ThreadX (can't wait to see how Microsoft poisons this one ;)RTX (any actual CubeMX support?  Really?  Documentation?)Other(s)?None/Bare Metal (including HAL-only)Just wondering... 

I am using STM32L476RGT6. I am trying to read and write operation in the embedded flash memory. I am unable to erase the stored data in the embedded flash memory. I am following method to erase :FLASH_EraseInitTypeDef EraseInitStruct; HAL_FLASH_Unlock();EraseInitStruct.TypeErase= FLASH_TYPEERASE_PAGES;EraseInitStruct. Page = 0x0807F800;EraseInitStruct. NbPages=1;EraseInitStruct. Banks= 1;//uint32_t  PAGE Error; if (HAL_FLASHEx_Erase(&EraseInitStruct, &PAGEError) != HAL_OK) {}HAL_FLASH_Lock();  

I have been learning NUCLEO-H563ZI using Keil recently.But I couldn't find the board level support package for the STM32H5 series on ST's official website.I have been download STM32Cube MCU Package for STM32H5 series,but i I can't find xx.pack file in the folder.

I am using NUCLEO-F756ZG board. Previously, I tried using ADC with timer trigger and it worked perfectly. Now, I tried to log the timer's pulse with another timer's input capture. It works but the captured timestamps seemed unusually slow. So, I disabled the input capture and just ran the ADC only. Now, it seems like the ADC is only sampling at half the rate I set. The settings from CubeMX are as following: HCLK = 216 MHzTIM1 (ADC trigger)PSC = 54 (4MHz timer), ARR = 4 (1MHz pulse), CCR1 = 2TIM2 (time measurement)PSC = 108 (1MHz timer), ARR = 0xffffffff (MAX)ADCChannel 2, Prescaler 4, Resolution 12bits, DMA continuous request enabled, EOC at end of single channel, Sampling time 3 cycles. This should give the ADC a maximum 1.8 Msps speed. Timer1 should be triggering it at 1MHz rate. The ADC should be able to finish each conversion before the next trigger. So, the sampling rate should be 1 Msps. I confirme

I would like to read external FLASH data using Memory Mapped mode, which is a function of OctoSPI.The environment is as follows. Use Board : nucleo l4r5ziIDE : Atollic TrueSTUDIO® for STM32, Built on Eclipse Neon.1a.(Version: 9.3.0)FLASH : W25Q64JV Currently, when FLASH data is read using Memory Mapped Mode, some data is unreadable.Specifically, 0xFF, 0xCC, and 0x88 are read.I have already confirmed that the data can be read as expected when read in indirection mode. The procedure is as follows. 1. Set for Memory Mapped Mode    Specifically, the register settings are as follows.

Hi Firstly, sadly I can not change to HAL as I don't have time to port this all across right now for this project dealine. I am trying to setup a PWM signal on PC6 on the STM32F100, I am pretty sure I need to set it as an alternat function but I have no idea how to do this or if I even need to. I can get another PWM signal to work on PB0 with the same setup but PC6 does not give me any output. Just checking but PC6 is TIM3 and channel 1 right ? I am starting to doubt myself on everything right now.   Any ideas would be of great help.   Currently my setup is as follows :   void SERVO_Init(void) {     TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure ;     TIM_OCInitTypeDef TIM_OCInitStructure;    

Hi I am using STM32H747I-DISCO board, where I am using FDCAN module, I tried with external loop back mode with FDCAN1 able to transmit and receive single message ID, but i want to transmit three message ID's and receive the data as per the message ID's. But I don't how to configure for multiple messages ID's please someone suggest any example with multiple message ID transmit and receive.

Hi,Im using stm32f103c8t6 along with w25q64 spi flash memory. I'm trying to do with this as a mass storage device but it is not working please help me with this.

I need level shifters, using QSPI signals with 1V2 logic (MCU can just be set for 1V8, so I need level shifters).I have realized: bi-directional level shifters for 1V2 are pretty slow (and rare). Level shifters which have a DIR signal (to turn the direction) are way faster, e,g, SN74AXC2T45. Therefore, I want to use Level Shifter (LS) which have a DIR signal.But how to get a DIR signal from MCU?Can I pause the transmission after sending CMD, ADDR and ALT (before DUMMY), so that I can turn the direction of LS? I do not think so.Can I get an indication signal from QSPI device when CMD, ADDR and ALT was sent?E.g. an INT (or flag) telling me the Preamble was sent, so that I can hurry to change the direction of LS? I do not think so.Can I use DQS signal for this intention? I do not think so (DQS does not work in SD

Hello.On a custom board with STM32U535CEU6TR, I can't have HCLK set to 160 MHz. At that speed, I get random hard faults. If I set HCLK to 80 MHz, then everything is fine, no more random hard faults.On the same board, with STM32U535CEU6QTR; no problem with HCLK set to 160 MHz.

Hello,I have already seen some old post about this topic, but without a clear explanation and solution. I have the following function, to configure and enable timer with the desired period. void HW_TIMER_Enable(uint32_t period){  LL_TIM_SetAutoReload(TIM6, period);   // reset counter register and prescaler counter register  LL_TIM_GenerateEvent_UPDATE(TIM6);  LL_TIM_ClearFlag_UPDATE(TIM6);   // enable timer and update event interrupt
