I'm trying to make a simple low power application using the STM32L4R9I-DISCO board where I draw some stuff to the display, put the DSI link in ULPM, go to STOP2 mode, wakeup using the RTC,bring the DSI link out of ULPMrepeatI've gotten to the point where I wakeup from STOP2 and try to bring DSI out of ULPM, but DSI_PSR resets to the default LP-11 stop mode on both lines, which confuses the HAL_DSI_ExitULPM() function. This is not the behavior I expected, as the RM says the DSI is frozen and register content is kept during STOP2.Interestingly, DSI_PSR is the only register that changes. Everything else stays the same. It's like the PHY just "forgets" what mode the lanes are in.Code is attached at the bottom, I've tried not disabling the DSI (thought maybe it was resetting) but it doesn't make a difference, DSI_PSR still changes.

STM32L4P5G-DK data brief refers to the UM mentioned above for detailed description. But this manual doesn't seem to be available. Any clues where to find it???

I want to read 10 tags. I can read less. but I want to read all of them in each round. how can i optimize it? labels are affixed to a metal box. My st25ru3993 reader is located in a refrigerator. I connected the reader to the computer. I entered the appropriate values ​​in the program (as shown in the video) but I can't get a proper result. Could you help?

Hi,I bought ST25RU3993-EVAL board.I want to reading tag's id. Can I make serial communication? I write console "minicom" .Then i set baudrate=3000000 and 8N1 and no flow control. But there is no text in terminal. How to make serial communication?

My board is STM32f072BBut I have a question, I can plug and reconnect to the PC in USB, but I think it is too much trouble and take time.Is there any way to reconnect without pulling the USB cable PC?

The power supply diagram shows the vssa pin of the chip, but it is not specified in the Pinout. It is also not clear the vddpa designation(= VDDRF1V5 or VDDSMPS) and why it is not connected anywhere. I also didn't find any information about vssrf. do you have a recommended connection scheme?

Hello, guys. I recently bought STM32H7B3I-DK and started playing with it. There are a few questions/issues I have:1) It seems that the board is recognized by the host PC only when it is directly connected to the PC's USB port. If I connect it through USB hub, the board is not visible and, consequently, not accessible. Do you have any idea why is that?2) I would like to perform printf style debugging of the code from STM32CubeIDE tool. I enabled SWV in Debug settings, opened SWV ITM Data Console, enabled port 0 and started trace. However, no printf messages are printed on the cosole. I am not sure how to set ITM block active. Would this be enough for transferring printf message to ITM block FIFO?#define DEMCR *((volatile uint32_t*) 0xE000EDFCU )   /* ITM register addresses */ #define ITM_STIMULUS_PORT0 *((volatile uint32_t*) 0xE0000000 ) #define ITM_TRACE_EN *((volatile uint32_t*) 0xE0000E00 )   void ITM_SendChar(uint8_t ch) { //Enable TRCENA DEMCR |= ( 1 << 24);

It asks to re-connect STLINK and press "yes". Nothing happens after. I've tried to install STM32CubeProgrammer to upgrade manually, but I could not get it running.OS X 10.15.4 java 14.0.1 2020-04-14Java(TM) SE Runtime Environment (build 14.0.1+7)What should I do?Regards,T

Hi there!I've just started working with STM32CubeIDE and after a bit of a vertical learning curve I'm slowly getting to grips with most aspects of it.I want to DMA to GPIO and there doesn't appear to be any way to do this through the .ioc GUI interface. GPIO ports can't be targeted as a peripheral by the DMA interface, and when you select a MemToMem option in the DMA section, the code that is generated by STM32CubeIDE doesn't have any user sections, and is hence effectively not able to be edited by the user.The other issue is that the MemToMem DMA option doesn't expose the most useful options like "circular" mode (it only exposes "normal") and doesn't give the option to provide any triggers either.Have I hit the limits of what STM32CubeIDE is able to do already? or is there some way to achieve this through the STM32CubeIDE interface that I haven't yet seen?BTW FWIW I'm using the very very latest release of STM32CubeIDE.Thanks,Luke

I am working on a project that I would like to import a keyboard into, like the one in the examples. How do I import widgets into projects?

Hi,I am using STM32L0 MCUI am using HAL_USART_TRANSMIT function to send data to a computerI am using Timer interrupt to ensure that UART transmits data every secondBut when i see log on computer ,its not exactly 1 sec, and this change also varies with baudrate ,so if Baud rate is 115200 ,getting data on uart every 1.3 sec (approx.) and it is not same everytime,whereas with 9600 it is slower .How to ensure that uart sends data at every 1sec ( with HAL API or LL API or any other way) ?timer code(using systick timer) void SysTick_Handler(void)   {   /* USER CODE BEGIN SysTick_IRQn 0 */   /* USER CODE END SysTick_IRQn 0 */   HAL_IncTick();   /* USER CODE BEGIN SysTick_IRQn 1 */   if(flag_uart_delay == 0)   {   counter_uart ++ ;   if(counter_uart >= 1000)   {   flag_uart_delay = 1 ;   counter_uart = 0;   }   }   }Main Code if(flag_uart_delay == 1)   {   //HAL_TRANSMIT_DATA ( ... )

My board is single ended antenna, no AAT, and no capacitive sensor connected. I use a similar analog config with NFC06A1, but select only one channel. And it works when 'wakeupEnabled = false', failed when 'wakeupEnabled = true'. What may be the problem here? Am I missed something?Thanks.

I have been stumped on this for a long time. My board is a Nucleo F767ZI, and my LCD is an ILI9341 8080 interface. The AN2790 note gives the following equations for asynchronous SRAM:And the example they give for an SRAM with 100ns write cycle time:These are the 8080 timing constrains from the ILI9341 datasheet:And here are the tsu(Data_NE) and tv(A_NE) ranges given for the F76xx series for asynchronous SRAM:What's really throwing me off is tACC. The ILI9341 only lists data on max read access times, but I'm only concerned with write operations right now. And using the max frame access time gives me serious troubles:Using an HCLK of 72MHz, and setting tv(A_NE) = 0 (If max is 0.5ns then I assumed I could set this to anything lower?):(DATAST + ADDSET + 2)*(13.8ns) = 66ns (min write cycle time for LCD)DATAST*13.8 = 15ns (min low pulse write width for LCD)DATAST = (340ns + 10ns + 13.8ns - 1)/13.8ns - 4 - ADDSET ------> DATAST = 22 - ADDSET ???Please help me understand where I'm messing u

I want to know how to fold curly braces. There are too many codes in the interface, so i hope the brace can be folded.

I have a new product using the stm32l486, and the GPIOG pins mentioned in the title do not appear to work as outputs, even though they are configured identically to the GPIO pins I am using for ports A-F. I cannot find anything in either the datasheet or the user manual about any pecularities to port G. But when pins in the GPIOG.ODR are set to '1' they definitely do not go high, and they are still read back as '0' on GPIOG.IDR. I also do not see anything in the errata for the stm32l486. I am correct in thinking that port G works like the other ports on this part?

Hi, I have STM32F407VE and this display which require 5V power:Is it ok, to connect it to 5V and to FSMC pins? I wont demage FSMC pins?

When I run the updater, and press 'start', an error occurs during the step, "Install IBUUI drivers". The error message isError installing C:\Program Files(x86)\STMicroelectronics\SPINFamily Evaluation Tool 3.2\Updater\Drivers\WinXP\IBUUI.inf driver. Access is deniedThis file is present in the location and has read access by all groups listed under the file properties. I tried to run the IBUUI Board Updater as Administrator (right-clicking on it and choosing that option) but this did not change the behavior.I also tried the alternate procedure to use STM32 ST-LINK software as described in the dm00268136 Spinfamily evaluation tool document, however once I try to connect to the MCU target, it says "No ST-Link detected." It is difficult to believe that I'd need another piece of hardware not required for my project in order to make the hardware I purchased work, since all the documentation on the EVAL6470PD says all I need is the EVAL6470PD and the STEVAL-PCC009V2.The environment is Windows

Hello,I have connected a BNO055 Sensor via I2C to a STM32WB Nucleo board. The sensor data is send by a BLE Service without problems after powering the device.However, if I change the code and upload via STM32CubeIDE or press the reset button on the device, the I2C connection seems broken... I do receive a HAL error from time to time... Question: is there a way to securely reset all pins apart from pressing RESET or is this more likely to be my software's problem?

Hello, i have a strange problem with x-nucelo-nfc01a1 shield.I get an i2c timeout but under different conditions it occurs in different places in code.My setup is nucelo board with stm32L073RZ and X-NUCLEO-NFC01A1 shield, and to communicate with M24SR module i am using xcube libraries, which i downloaded from st.com site.Case 1.I2C is configured to 100kHz.I2C timeout occurs during initialization phase. From my observations it looks like the transmission holds during sending verify command (M24SR_Verify()).The I2C_WaitOnTXISFlagUntilTimeout() function in HAL_I2C_Master_Transmit() returns I2C_TIMEOUT and it is always in the half of transmission.The verify command is 24 bytes length, and when timeout occurs hi2c.Instance.XferCount is equal to 12.So in result i cannot even initialize the module.Case 2.I2C is configured to 400kHz or 1000kHz.Initialization phase passes with success. I can even write and read an URL using TT4_WriteURI() / TT4_ReadURI().But when i try to write for example vcar

Hi,Please can someone help me, I am quite new to this hardware.I have a MKI109V3 eval board and trying to test MKI197V1 LSM6DSOX adapter. I've downloaded the Windows software package and installed Unico V9.8.1.0 and the COM port driver V1.5.0. I've also updated the firmware of the MKI109V3 to V3.6.36 via STM32CubeProg.In Unico, when I try to select device MKI197V1 I receive this message:"ERROR: The adapter board has not been recognized.The WHO_AM_I register does not match the device selected."I am unsure why I'm getting this error message. Any help would be much appreciated.Many thanks,Liam
