Hi everyone.I am recently working on stm32 chip and found a page show the power consumptionseems GPIO port C and F can save half the power than A and Bshould i always consider to use gpio port C and F ?or the consumption is too little that we don't need to care about?

I am trying to flash a custom PCB having STM32H743IIK6 MCU using SWD interface. I have tried below methods but all are Failing. Flashing using 'STM32CubeProgrammer' using all 'Mode' and 'Reset Mode' options FailedFlashing using STM32CubeIDE tried using STLINK SWD and J-Link SWD FailedFlashing using STM32 ST-Link Utility Failed.Below is the Schematic of the programming and power supply section of the MCU.I have assembled 2 different boards and in all 2 boards, Most of times, I am getting 0V on VCAP pins. but sometimes this VCAP voltage fluctuate around 0.7V to 1.1V. 

I am trying to detect the NFC tap and try to raise a flag whenever a flag is seen and to do the same function each time.is there any example available?I am able to read and write to EEPROM but I don't get any idea how to detect a tap

Hi there,I am new to motor control and I am trying to set up my P-Nucleo-IHM03 kit with MC Workbench 6.1.2. I would like to use FreeRTOS in combination with the 6-step algorithm but in the "Application Configuration" under "FreeRTOS" it is stated: "Selected hardware boards do not support this feature".I was wondering why FreeRTOS is not supported in this case?With the *same hardware* and the FOC algorithm selected there is no such statement and I am having no issues generating a FreeRTOS project. So for 6-step I would now try to add FreeRTOS in STM32CubeMX, but I would like to know if there is any adamant obstacle that would prevent the combination of 6-step with FreeRTOS either in hardware or the 6-step library?   Thanks     

Hello,As I understand from datasheet if you use 64, 81, 100, 132 or 144 pin package there is separated power supply domain for USB transceivers, i.e. VDDUSB which should be connected between 3.0-3.6V or connected to VDD if USB is not used.However, 48-pin package does not have VDDUSB, so the question - if I am design my board around 1.8V will this MCU in 48-pin package work as intended, i.e., USB will enumerate and etc. ? Or I should switch to 3.3V, use level shifters from 1.8V to 3.3V?Thanks in advance!

I just read this document : https://www.st.com/content/dam/specialevents-assets/dc22/pdf/room-3-1-stdevcon22-session-nfc-for-wireless-charging.pdf there are two daughter boards, one based on ST25R3916 (NFC reader) and the other based on ST25DV-I2C (NFC dynamic tag). Both use STM32L476 as motherboard.However, the 3.3v power supply that I directly connected to L4 with EH energy in st25dv did not activate successfully. May I ask how to use NFC power supply to power MCU on the side of the label?

Hello.I want to use NUCLEO-G491RE with MCSDK6.1.2. However, NUCLEO-G491RE does not exist in the list of "Control" of MCSDK. If I have a NUCLEO-G491RE JSON file, can I import it? Where can I get the JSON file?Thank you.

Newbie here.I discovered the STM32 Nucleo development boards and there seem to be lots of models.After clicking and clicking I can't seem to find the one for the STM32H747XI - TFBGA240+25 Package...Or at least one with the same number of pinouts... even if in another package.Most of the ones I saw seem to imply they are fr 144 pin packages...but the STM32H747XI - TFBGA240+25 Package has 265 pins per the data sheet page 60Hopefully some kind soul will direct me to the proper STM32 Nucleo board for use with the...STM32H747XI - TFBGA240+25 Package.Thanks.PS - as I try and learn how to navigate the st.com website after awhile it tells me I don't have access to that page.I've had this happen with Chrome and with Microsoft Edge after clicking around for awhile trying to learn where things are. Anyone have any ideas with what is going on with that? Thanks again.

I have a scroll wheel with selected item. Is it possible to update the selected item, e.g. its font color, when the modelListener notifys the screen that a certain event has happened?Example: Let's assume the model contains a counter and notifys the screen if the current value is even or odd. For even values, the text of the selected item in the scroll wheel should be blue and for odd values green.How can I achieve this? I managed to kind of do it by calling a function that does the follwing:void ScrollWheelScreenView::updateSelectedItem { touchgfx::Drawable* d = scrollWheel1SelectedListItems.getDrawable(0); ContainerSelectedScrollItem* cc = (ContainerSelectedScrollItem*)d; cc->setOddOrEven(); cc->setTextAndIcon(indexCenterItem - 1) }This function is called in the presenter-implementation of the notify-function. The text color is updated, but the text itself is not always correct: If the odd/even-update happens while scrolling, the text of the next or previous item is displa

if i use static UART_HandleTypeDef huart8; in main.c . when i want to run it in fpvisionai.c  HAL_UART_Transmit(&huart8,etc) say huart8 undeclared , should i use include <main.h> in this file,o how to set UART_HandleTypeDef huart8 as global variable

if one pin have two pin name for example d14 could be mcu pin as PD12 ,o PA9 at gpio port. But for gpio_init()should be PD12, the PA9 is for which part to use?

Greetings to all, new to the STM32Cube environment hence the baby pic profile.   I created my project, a medium-complexity scale wherein 5 HX711s are feeding my STM32, and uploaded to my target, a Nucleo-L152RE.   Software compiles without error, for what that's worth.  It loads, declares victory and terminates where it should just run indefinitely.  To see what is happening I loaded CubeMonitor. At first I got [not connected ! JTAG/SWD error (f5)] so I added this to my code: #define DEBUGGER_ON 1 //REMOVE BEFORE FLIGHT #define LOW_POWER_DISABLE 1 //REMOVE BEFORE FLIGHT   I had to run the script in debug mode for this to take affect and, interestingly, it did not terminate, nor did it run.  It paused somewhere and gave me this error in the CubeMonitor      [not connected ! Device not opened (5)] Probe_in and Probe_out are the same and defined like this: I can hit the 'Blink the LED' and that works. Back to the IDE, when I hit

My project (Stm32H753) has 2 identical external ADCs, one on SPI2 and one on SPI3. The one on SPI3 is working fine, but I am having problems with SPI2. The code for them are the same, except of course different 'hspi' and pin assignments.The SPI is configured to use PC2 and 3 as MISO and MOSI, I probed SPI signals, everything looked fine except on MISO (ADC output) the voltage is only 1Vpp. Open the analog switches (SYSCFG->PMCR) didn't help much (instead reading all 0s, openning the switches gives all 0xfff readings. I have internal pullup for MISO).Just curious, when PC_2 and PC_3 are labeled with '_', are there any special steps to use them for SPI2? 

I debuged my software on the STM32F722ZE, when I suddenly lost connection to it. I tried to connect to it with ST-Link V2 and Segger J-Link. Error message from J-Link commander is: Can not attach to CPU. Trying connect under reset. Connecting to CPU via connect under reset failed. Error message from ST-Link V2: Error finishing flash operation. Failed to erase memoy. See picture: I then took a look at the config with CubeProgrammer: How is it possible to have 0xFF as RDP Byte? Write protection is not active are all checked. When I try to perform a mass erase I get Error: Mass erase operation failed. How can I recover from this? Is it possible that I locked myself our by acciedent? I would say it is rather unlikely to do this while debugging. What else could have happend? Thank you in advance for every answer.

Hello,the STEVAL-MIC007V1 with the IMP23ABSU is on the first sight quiet interesting with the microphone bandwith up to 80kHz. However (due to imprecise reading from me) it turned out that this is a analog MEMS microphone. The STEVAL-MIC001V1 with the MP34DT05-A on the other hand is a digital MEMS microphone which puts out a PDM signal, which is in my opinion/application more suitable. But the 80kHz Bandwidth is more interesting toward industrial applications, but when using the STM32L496 the maximum frequency for the ADC is 80MHz and I would need 160MHz to sample the signal without aliasing. My question is: Is there an alternative digital MEMS microphone with 80kHz bandwidth with PDM output (STEVAL?) or is there a "easy" preprocessing implementation for the IMP23ABSU (also with minimal external electronic)?Best regards,ChRegBrg

Hi. From DS of TS555 I'm not clear about RESET acitve low level. In DS VRESET is given 0.4V(min), 1.1V(typ), 1.5V(max) for +25°C and 0.3V...2.0V for whole temp range, see attachementCan someone help to get min/typ/max level for RESET is active and the level RESET is inactive at +5V supply and -25°C....+85°C.Thx Tom

Using TouchGFX Designer 4.22.0Why it is not possible to make a circle progress much like a car dashboard would have. Zero is at about 7 o'clock and full is at 4 o'clock.The circle progress always starts at 12:00. No mater what parameters I enter.Is there another method of achieving similar effect?

Hi, we want to read and write data to st62t65c6 chip. I looked for a topic here and found one answer which suggests us to get an ST6-EPB but we can not find it anywhere. Is there any other way to achieve this? Regards

Hello,I'm trying to send some data via UART and DMA on a STM32F072, but with the low level functions. This works perfectly when using the HAL-function HAL_UART_Transmit_DMA(), but I'm missing some information for the low level functions. I configured everything with CubeMX and have this example "code" running:// Disable DMA to load new length to be tranmitted LL_DMA_DisableChannel(DMA1, LL_DMA_CHANNEL_4);   // set length to be tranmitted volatile uint8_t uart60_tx_buffer[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; LL_DMA_SetDataLength(DMA1, LL_DMA_CHANNEL_4, sizeof(uart60_tx_buffer) );   // configure address to be transmitted by DMA LL_DMA_ConfigAddresses(DMA1, LL_DMA_CHANNEL_4, (uint32_t)uart60_tx_buffer, (uint32_t)LL_USART_DMA_GetRegAddr(USART2, LL_USART_DMA_REG_DATA_TRANSMIT), LL_DMA_GetDataTransferDirection(DMA1, LL_DMA_CHANNEL_4));   // Enable DMA again LL_DMA_EnableChannel(DMA1, LL_DMA_CHANNEL_4); // how to start sending with DMA?!   // this works, but is not with

Hi,I have a problem with an 24LC64 EEPROM, it is not a bad chip because i have tried 2 on diffrent boards. I am using the STM32G0B0  This are my I2C settings:I am using this libary : https://github.com/nimaltd/ee24/blob/master/ee24.cI only get 255 back when i read something.   

If i use the serial interface USART1 HAL_UART_Transmit()( is directly available as a Virtual COM port of a PC connected to STLINK-V3E USB connector CN2) could show in com9 in pc, but uart8(D0/D1) in com9 didn't show anything, This result should be right o bad? if i use putty which port should be for uart8?
