STM32 MCUs Products

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

I am using STM32L562, we have replaced MX25LM51245G with, IS25LP128F external flash.We have integrated its driver and it is working fine. But we want to flash binary using STM32_Programmer_CLI.exe and or STM32Cube programer.For that, I have tried to develop it's loader using the below repositoryhttps://github.com/STMicroelectronics/stm32-external-loader/tree/mainI have done the following changes in the "MX25LM51245G_STM32L562E-DK" projectRemoved related Flies and added IS25LP128F filesI am able to compile it sucessfully.Changed Dev_Inf.c file as belowstruct StorageInfo const StorageInfo = {#endif  "ISI25LP_STM32L562E-DK", // Device Name + EVAL Borad name  NOR_FLASH,        &

I am using an F303RE and UART communications for a project.I'm using all 5 uarts, all with the HAL-library interrupt based transmit and receive.The main communication protocol is MAVLINK, with one of the UARTs being SBUS.My issue:After a random amount of time, a UART channel stops receiving messages.It is also not always the same channel to stop, and it might be multiple channels to do so (not at the same time).Note:I'm dealing with this issue for 3 weeks now, without any progress.I know the 'correct' way would be to write a new HAL, but I don't have resources or knowledge to do so at the moment.I am using HAL_UART_RxCpltCallback, this way:(There's HAL_UART_Receive_IT at the end of each reading function)(I know the code isn't pretty, a switch-case would be a better fit for readability)void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { USART_TypeDef *uart =

Hello. I am confused about the amount of flash on an STM32F105VBT6. From the overview for the STM32F105/107 devices, I gather that this MCU should have 128 Kbytes of flash. And in STM32CubeProgrammer, in the lower right, it says that the target has 128 Kbytes of flash as well. However, I was able to program 139 Kbytes of flash, and it seems like I can successfully write 0x00000000 to the 4 bytes at 0x0803FFFC to 0x0803FFFF. So, the MCU seems to have 256 Kbytes, which is what an STM32F105VC should have. Does anyone know what's going on?

I'm trying to configure NUCLEO demo board at 480Mhz but I'm not able in any way, the following clock configuration seams to be correct, no conflictsBut the code will permanently hang on on the following configuration lineIf I comment the line while(!__HAL_PWR_GET_FLAG(PWR_FLAG_VOSRDY))all seams to work correctly, why?Chip revision seams to be V so It will be capable of 480MHz

Good morning,I am working with a board mounting a STM32L0x3 microcontroller. My SystemCoreClock is 32 MHz and TIM12 is clocked at 4 MHz. TIM12 has been configured in order to work in Capture Mode on Channel 1 (falling edge).The ISR does what is listed belowvoid TIM21_IRQHandler(void){/* USER CODE BEGIN TIM21_IRQn 0 */ /* USER CODE END TIM21_IRQn 0 */ GPIOB->BSRR = GPIO_PIN_11 ; /* USER CODE BEGIN TIM21_IRQn 1 */ /* USER CODE END TIM21_IRQn 1 */} To my surprise, using an oscilloscope, I noted that time elapsed since the falling edge of the signal the other pin is set is ab

I am experimenting with PWM DMA on STM32F407VET6. The code creates pulses of increasing width.If I enable the output compare preload, the number of pulses is 2 instead of 6.The first pulse at startup is the default setting from the configuration in MX and not the first DMA value. This makes sense as preload of output compare means to load when timer = 0 (if I am not mistaken).To make sure PWM values are not one off, I disabled the preload of the output compare register. In that case I get only 2 pulses and pulse generation stops? Why do I get only 2 pulses in that case?void HAL_TIM_PWM_PulseFinishedCallback(TIM_HandleTypeDef *htim) { HAL_TIM_PWM_Stop_DMA(&htim2, TIM_CHANNEL_1); printf("HAL_TIM_PWM_PulseFinishedCallback: Transfer completed\n"); }     /........................../ Main loop extract:   for (int i=0; i<6;i++) pwmData[i] = 1+5*i; /* USER CODE END 2 */   /* Infinite loop */ /* USER CODE BEGIN WHILE

Hello, I am using an STM32L462 microcontroller with a crystal from Wurth: 830 016 178This crystal has a load capacitance of 6 pFI calculated the two load capacitors CL1 and CL2 to be 4.3 pFNow, everything is working OK, and the RTC is running fine...But as soon as I measure the signal with an oscilloscope ( 10 M ohm probe 12 pF) the signal diminishes to zero)Now, I understand that I add an additional 12 pF to the loop, but I am afraid that my solution is not stable.The drive level in the firmware is set to low.And if I turn it to high, it makes no change.The traces to the micro are 4mm and the other 5 mm long. In the reference manual of the STM32L462 they use also a chrystal with a load capacitance of 6pF ( with stopmode specifications they tell), but they have 6.8 pF capacitors can anyone advise

I have a B-L475E-IOT01A2 board. I'm trying to use the onboard microphones to record audio, using the DFSDM peripheral, and then send the data over UART to my PC to play it back. The thing is, the data I get is basically just static.Here is how I configured the DFSDM peripheral in CubeMX, based on the "DFSDM_AudioRecord" example for the eval boardsSource for output clock is audio clock. SAI1 is clocked at 13.714286 MHz, the divider is set at 5 to get 2.74 MHz.Channel 1 and 2:SPI with falling (resp. rising) edge, internal SPI clockOffset = 0, right bit shift = 0x02Analog watchdog (I think is unused): FastSinc, oversampling = 10Filter 0 and 1:Regular channel selection 1 (resp. 2)Continuous mode, software trigger, fast mode and DMA mode enabledNo injected channelsSinc 3 filterFilter oversampling : 64 to get 42.85 kHz. Integrator oversampling: 1 (bypass).

For a project, I need to find a stm32 that has a minimum of 5 timers that can read encoders, and it has to have a CAN-bus peripheral.Is there a way to do this in the part selectors? I can select the minimum number of 16bit timers, but not all 16bit counters seem to support encoder input. Any way to do this without manually reading all the datasheets?I did try to automate this using the XML files in the data folder of stm32cube, but I did not really find a way to detect if a 16bit counter support encoder input.

We need to make a master PWM that vary duty cycle from 1 to 35% and have a phase shift with two other pwm (this two other pwm are in phase and duty cycle 50%, but one starts with one and other starts wiht zero.). The phase shift should vary from 1 to 360 degrees. All the pwm have the same frequency and should be possible change the frequency for all. I tryed output compare between 3 pwm, but only works at 50% duty cycle.

Hi all,I want to drive Humidity and Temperature Sensor SHT4x(address is 0x44).I finished the driver code in STM32F103C8 with HAL lib, but when I used the same driver code in STM32F429IG with HAL lib, the HAL_I2C_Master_Transmit() always returned HAL_ERROR. After debugging, the error comes from the following code:This topic said the reason is the I2C master did NOT receive the ACK by slave.But I catch the signal by an oscilloscope, and it seems the sensor already ACK:
