STM32 MCUs Products

Hello,I have a custom board with a STM32L010C6 MCU, which periodically reads 3 bytes (24 bit array) from an external component through SPI.I only need SCLK and MISO since the frame resets using a timeout.I configured the SPI as Only-Receiving Master, which didn't work OK. Now I am using the SPI peripheral as a Full-Duplex Master with software NSS and I perform data reads by polling function HAL_SPI_Receive().It seems to work OK, with some delay between bytes.The problem is that I periodically get bad data in the MCU. I identified that this happens when the SPI clock is n

Hello.The MCU currently in use is STM32L031G6X.In order to minimize current during sleep, the external circuit currently uses 100K pull-down to PB3 to set it to "Rising Interrupt" and UART 1 for testing.When measuring the current, remove the external console jig connected to UART1.I set it to standby mode, it's 3.3uA, but wake it up with RTC interrupt and PA0WAKE pin, the system will resetIt doesn't fit the mode I'm trying to use, so I'm trying to minimize the current in stop mode.The code in stop mode is as follows.If i disabled SystemPower_Config(); will wake up well in RTC and PB3 button interrupts, but the current will be measured at 22uA.If I enabled SystemPower_Config();, it can't get out of the sleep without resetting it after going into the sleep.I

Hey. I tried to setup `printf` using the following forum post. I am using the `NUCLEO-L4A6ZG`.Here what I've tried so far. I connected the `USART2` to the Pins `PA2` (RX) and `PA3` (TX):(By default LPUART1 was configured and connected to PG7/8, since the forum post used USART2 I used it as well.)After the configuration was saved, and the code generated, I used the code from the previous mentioned forum post. Here a shorter and with comments removed version:

I am trying to run BDMA on STM32H7B3 in double buffering mode. During debugging, I can see that some registers are missing in BDMA->CCRx. According to the documentation, DBM should be located at position 15 and CT at position 16. Where can I download the corrected STM32H7B3.svd file?

Hello,I'm testing USB Power Delivery (in dula role power) over STM32G0.I used ST wiki guide : https://wiki.st.com/stm32mcu/wiki/Introduction_to_USB_Power_Delivery_with_STM32It's works except for a specific case :STM32G0 is configured in DRP-Source with PDO 5V/2AI connect to it a Sink which required 5V/3AThen the Source can provide this powerIn this case, I would like that USB power works at default current (500mA)Unfortunatly, it doesn't work and USB-PD power negociation restarts indefinitelyIs there a way to correct that ? 

Hi,I would like to know if it's possible to use M95P32 in memory mapped mode on STM32G474 QSPI interface.Thank you.             Andrea

Hi,We have now a problem with some boards, H7A3ZI or H743ZI , when switching off :   RTC stops working !RTC is powered on VBAT with a standard CR2032 and was working as it should on about 500 boards since more than a year. Now (some) batteries loosing voltage and we get errors, because RTC no more working.This happend at first at about 2,7V (cell voltage), now even on new boards with 3,0V cells.The problem starts at the moment of power off, when VDD falling (to 2V or so) , the internal switch going to use the VBAT as supply for RTC and backup ram. On affected boards is about 5 ms (!) long the LSE oscillation away, then starting (on VBAT supplied now) again - or no more, showing the error on next startup.Is there anything we can do, to avoid this ? Or is there some "known problem" with the H7 series, when switching to VBAT ?   (In errata i found nothing about this problem.)

I followed this tutorial https://medium.com/@pasindusandima/stm32-usb-virtual-com-port-vcp-bc7cb1bd5f5 to set up a USB data transmission from my board to a Virtual COM Port. After building the project and running with debugger, I only see "STMicroelectronics STLink Virtual COM Port (COM5)" and "ST-Link Debug" on my device manager. After using PuTTY to listen to serial port COM5, I see no activity in the terminal. However, I noticed that the tutorial does not use COM5 and instead uses "STMicroelectronics Virtual COM Port (COM10)". But when I run my program, no new USB devices show up, and only the original two mentioned before are present. How can I get the correct COM port to show up on my device manager? 

I have my OCTOSPI1 as QSPI working - in "indirect mode", now using DMA: it generates a very clean waveform (no gaps between words or bytes as in "polling mode", a smooth waveform).I use also OCTOSPI1 as a "regular SPI transmitter" (acting as SPI Tx). But due to fact that OCTOSPI is NOT a "regular SPI" (it is NOT "full-duplex"): I use SPI3 as a SPI Slave RX:I connect QSPI SCLK with SPI3 SCLK and SPI3 MOSI is QSPI DIO1 (as MISO). Now I have shared pins for QSPI and a regular SPI on the same QSPI pins. I works.I use also SPI3 Rx DMA. It makes the SPI waveform way better (no gaps).The project is here (if you want to see how to use DMA for OCTOSPI as QSPI and SPI3 as Slave Rx for regular SPI):https://github.com/tjaekel/NUCLEO-U5A5JZ-Q_QSPI What I have realized:Callback co

Hi, I wonder if someone can recommend an alternative to STM32H563ZIT6 mcu for minimum 11 Uart peripherals ona single IC. Preferably if the IC is from the STM32F series.NOTE: The above quantity achieved by treating the USART ports as UART using 144 pins STM32H563Thank youSAM 

Hi ,I am using an STM32F205 for my project. We were using HSI as the clock source before and found out that HSI will not work very well with high temperatures for UARTs, So we added an External crystal clock (16Mhz) but I am unable to get Comms out of UARTs now (There are some random values coming through uart sometimes). This is my clock configRCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE; RCC_OscInitStruct.PLL.PLLM = 14; RCC_OscInitStruct.PLL.PLLN = 240; RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV2; RCC_OscInitStruct.PLL.PLLQ = 4; if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) { Error_Handler(); } RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK

I used STM32F072C8T6.ADC - IN0, IN1 set.An application that measures temperature with an NTC temperature sensor.​   ​PullUp resistance 10K was connected to Vdd (3.29V) and PA0, PA1..When the HAL_ADC_Start_DMA function is executed, the voltage of ADC - PA0, PA1 is measured by 3.7 (V).If the HAL_ADC_Start_DMA function is not run (normal GPIO call setup), 3.29(V) is measured normally.How can it be higher than the input v

I'm seeing strange behavior trying to write to the ADC1_JSQR register. This register controls the channel sequence and the trigger source of injected conversions. After enabling the ADC (ADEN=1), a write to bits 7:0 (JEXTEN, JEXTSEL & JL) locks out further writes to ADC1_JSQR so that subsequent writes are ignored. Writes from both C and gdb seem to exhibit the same behavior.Paragraph 15.3.10 "Constraints when writing the ADC control bits" in RM0365 makes me wonder if writing to the ADC registers in the wrong order. For all bit fields in ADC1_JSQR, the manual states: Note: Software is allowed to write these bits at any time, once the ADC is enabled (ADEN=1).I have two Nucleo-F302R8 boards and both work the same.Is this a hardware bug or am I doing something wrong? static void setup_adc(uint32_t adc) { uint8_t regular

I've been testing ST chips and started with the STM32F411 using my own board for testing with the SD card, which I wasn't able to get working. Thinking it was my fault, I ordered the STM32F412 Discovery board and I can confirm that using the examples, the SD card works fine. When I try to get it running on my own, without examples, configuring through the Device Configuration Tool, I'm unable to make it work. I must be doing something else wrong, but I don't know what, and I've been struggling with it for two days now. Can you help me, please? Thank you and regards.

Hi ST SupportI would like to request the FIT report for the STM32L071CZT3, many thank.   

Good morning, I have to do a porting from a project developed on STM32F423 to an STM32U5A5The starting project used the wiced sdk, with the supported platform STM32F423.If I understand well, for STM32U5A the wiced sdk is deprecated, and it would be better to use the package Infineon.AIROC-Wi-Fi.Bluetooth-STM32. Is it correct? Is there any application note to help me to do the porting? or to use the infineon package with STM32CubeMx?

Hello, I am working with "Mastering The STM32" book and faced with one problem: cannot find the option as in the book to activate any timer using CubeMX. I am using STM32 blue pill STM32F103C8T6. Why I can't find the activate option of timers?

Hello, I hope you are doing great.I have two NUCLEO H743ZI2, one of them is MB1364E, and the other one is MB1364C. They are totaly the same but there are little differences and I would like to find them and make them same, since I would like to use them in the same application.I searched a lot and I found that there are some differences between them in the PCB and components.For example,1- SB1, 0 ohm 0603 resistor is deleted form the PCB in MB1364E.2- SB45, a 0 ohm 0603 resistor is added to the PCB in MB1364E.The question is that is there any other differences that I could not find?Is there a PDF which explane the differences?Best regards,

Hi all,I'm struggling for days why my RTC wakeup doesn't work.The program is running FreeRTOS, but I want the uC in Lowpower Sleep for 3 minutes.So I set RTC on 1Hz, counter 180 and internal wakeup.Activated the EXTI RTC interrupt.But it immediately exit SLEEP after 1 sec or so.I found this topic, but haven't luck so far:https://community.st.com/t5/stm32-mcus-embedded-software/clearing-the-rtc-wutf-saving-your-sanity-by-sharing-my-hard/m-p/200677 void goToSleep(void){__disable_irq();__HAL_RTC_WAKEUPTIMER_CLEAR_FLAG(&hrtc, RTC_FLAG_WUTF); vTaskDelay(pdMS_TO_TICKS(1000)); H

Hi folks,I hooked up the B-G474E-DPOW1 board using the micro USB cable to the USB port on my laptop. I confirmed that all the three LEDS (LED6, LED7 and LED9) turn on as expected. But when I open up a PuTTY serial console window by connecting to the right COM port, I do not see any boot up messages. Do I have to enable some settings, to see the boot up messages?Thanks!Best Regards,Gautam

Hi,I am trying to configure the pin PC13 in my STM32F411 device as Input with Pull up option and it is connected to a rotary encoder. At initial bootup time, the pin is in toggle state and after that, it is set to 0. In the same project, I also configured the RTC. This PC13 pin has an alternate function as RTC_AMP1, RTC_OUT, and RTC_TS. Could you please explain the reason for this?Thanks and RegardsVrinda R

Is it not possible to read the Unique device ID registers (96 bits) on STM32L051 through the bootloader? I get a NACK on that address.
