We have a flutter application that is connecting to the ST BLE sensor chip via native bluetooth. We listen to the mems, pressure, accelerometer, and sensor fusion sensors to save to 4 files on the app. The ST SDK was giving us the observed blocking of pressure sensor so we switched to Native bluetooth in hopes it was just an SDK issue, but seeing same issues with bluetooth.When the pressure sensor is being listened to, only audio + pressure data is received. the other 2 sensors have nothing.When disable listening to pressure, the other 2 sensors + audio receive data.We have put breakpoints for where we write data from the 3 sensors, and with pressure sensor not active, we can see the data being saved, but when enabled, it only fires on the pressure sensor write to csv function and the other 2 are never triggered.It appears that the pressure sensor does not allow for interrupts and is operating in a sync mode when it comes to the other sensors.This is proved by only listening to the oth

Hello all, I have a very strange problem with Debugging. I am using a STM32H723xx microcontroller for my project. I have some debuggers like ULINK ME, ULINK2, JLINK, ST-LINKV2 and V3. All debuggers show the same issue.I access the external SRAM via FMC as shown below:volatile __attribute__((at(0x60000000))) SRAM_DATA sram ;   [...] SRAM_DATA lram; sram_to_ram ( &lram, &sram, sizeof( SRAM_DATA ) ); [...]   static __inline void sram_to_ram ( uint16_t *dst, volatile uint16_t *src, uint32_t size) { while ( size-- ) { *dst++ = *src++; } __ISB(); __DSB(); }The access probably works. I have no problems here. The function is called in the interrupt context. It can block for up to 100 µs. The cache is active, so I used __ISB() and __DSB(). The MPU settings of the SRAM are set correctly.I am using Keil V5 IDE for this project. When the above code is in my code, after a few seconds I get the following message: "Debugger - Cortex-M Error - Cannot access

Hello,This is my first post to this forum.I've been trying for several days to configure a project with TouchGFX and STM32CubeMX. First, I want to thank you all for all your message I found on this forum and which helped me.Initially, I wanted to use STM32CubeIDE & TouchGFX but I realized very quickly that it is nearly impossible for now.So, I tried with Atollic TrueStudio. I succeeded in getting rid of compilation errors and having my GUI on my STM32F746 DISCO except that the touchscreen didn't work. I'm stuck here and I will maybe open an other post to find a solution about it (I can post my project if you want)I don't want to lose more time so I'm asking here: in your opinion, on which IDE is it the easiest to configure a new project?I can't pay for an IDE and I would prefer to use Atollic TrueStudio or STM32CubeIDE because I wanted to stay as close as possible from the ST "universe". SW4STM32 is simplier to configure than Atollic TrueStudio?I'm using a STM32F746 disco and STM32

Hello, I have a custom board with a SMT32L031F6P6 on it: PA2 and PA3 USART2 channel seems not to work even if they are correctly set in the .ioc file.I have tried the same code on the NUCLEO-L031K6 board using VCP-TX and VCP-RX (PA2 e PA15) default pins and it works correctly, but if I move the UART pins to the Arduino-compatible ones, PA9 and PA10, it dosen't work anymore.What am I doing wrong? The UM1956 says that "Only one USART is available and it is shared between Arduino Nano and VCP. The selection is done by remapping (no hardware configuration to change)." but I think something is missing.This is the working code, in CubeIDE v.11.0:... #ifdef __GNUC__ /* With GCC, small printf (option LD Linker->Libraries->Small printf set to 'Yes') calls __io_putchar() */ #define PUTCHAR_PROTOTYPE int __io_putchar(int ch) #else #define PUTCHAR_PROTOTYPE int fputc(int ch, FILE *f) #endif /* __GNUC__ */ ... int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_USART2_U

I'm writing initialisation script.Project repo is cloned into my empty workspace.At the moment the user must initialy run STM32CubeIDE select empty workspaceCall File > Open Projects from File System ... > select Folder and confirmThis action is what I need to implent in my initialisation script.What would be apropriate command for it?

Hi,I am trying to set the GPO pin on a ST25DV based device from an Android app. I am using the following code:AndroidReaderInterface reader = AndroidReaderInterface.newInstance(mTag); try { ST25DVTag mTag = new ST25DVTag(reader, ((Type5Tag) mNFCTag).getUid()); byte response = mTag.manageGpoCommand(ST25DVTag.GpoCommand.SET, (byte)0x00); Log.i(TAG, "Response: " + Helper.convertByteToHexString(response)); } catch (STException | Exception e) { Log.w(TAG, "ManageGPO failed: " + e.getMessage()); }This is what we concluded so far:1. The NFC device really receive the command and set the GPO. We confirmed this with oscilloscope.2. We tested the app on 2 different Samsung phones and Xiaomi. The same code executed fine on one mobile phone but throws an exception on two others.What are we doing wrong?Many thanks in advance.

Hi all,Does anyone know if I can watch a past Online workshop called 'Easily add intelligence to your products'? I missed the scheduled one on the 4th April and would like to watch it if available.Thanks.

Hi All,Can somebody point me what is a reason for 2 sec delay at PHY driver for LAN8742?I mean code below at function LAN8742_Init() inside file lan8742.c.if(status == LAN8742_STATUS_OK) { tickstart = pObj->IO.GetTick(); /* Wait for 2s to perform initialization */ while((pObj->IO.GetTick() - tickstart) <= LAN8742_INIT_TO) { } pObj->Is_Initialized = 1; }I am working at project with STM32H735 and ThreadX+NetX Duo. As PHY I use KSZ8081RNA, but I found that same delay need be there as at LAN8742 driver. Without this delay Ethernet does not work. With 2 sec delay works auto-negotiation with 100MB switch, but not with 1GB switch. For 1GB switch need be there ~3 sec delay.I am not sure what is going on here. I didn't found anything related to this delay at KSZ8081 datasheet, IEEE spec for auto-negotiation or at STM32H735 errata. I will be gland for any comment.Thanks.Regards,Jan

Hi,I have acquired a new STM32G031 microcontroller that has not been previously flashed and have observed an unexpected behavior when powering up my circuit prior to the initial software upload.Upon further investigation, I discovered that multiple registers were not at their reset values, but instead at different values that were not anticipated. Specifically, the registers of GPIOA (such as MODER) had critical (in my application) pins set to pull-up (e.g., MODER set to 0xEBEB FFAF).As such, I would like to know:Is the initial state of the registers documented anywhere? I was unable to find such information in the reference manual (RM0444.pdf).When in production with the final PCB already assembled, what is the safest approach to ensure the registers are at their reset values even when flashing fails (e.g erasing the device prior to flashing)?I appreciate your assistance with this matter.Note: While I understand that the safest solution would be to ensure that the external circuit can

I´m using the l9616-tr CAN transceiver, but i have no signal of CAN comuniccation, i think maybe tx and rx configurations pins are inverted.

Hi,​After I configure hospi1->Init.MemoryType = HAL_OSPI_MEMTYPE_HYPERBUS;​If I still want to send a command using CA[47:0] (or DQ[7:0]) and read back data such as device ID, how should I approach this? Is there an example code I can refer to?I am wondering if the command type (sCommand) needs to be OSPI_HyperbusCmdTypeDef? the max address is 32 bit but I need to send 48 bit.​or should I use OSPI_RegularCmdTypeDef? Then set MemoryType to HAL_OSPI_MEMTYPE_HYPERBUS later after I read all the data I want?Thanks in advance.

Hi, Is there any example of how to interface a NOR FLASH QUADSPI memory using the OCTOSPI interface used in the H72x, U5 or H5?

I am currently developing using STM32mp157fad and have a question. Here are the steps I have taken:Used STM32CubeProgrammer to upload the stm32mp157f-ev1 image to an SD card.Used STM32CubeMX to configure the GPIOs to be used with stm32mp157fad, generated code, and copied the device tree generated by the code generator to the SD card with OpenSTLinux installed.I'm wondering if this method is valid for use. If this is not the correct approach, I would like to know more information.

Dear all,ST brought a new feature to the STM32H7A/B and some L4+ MCUs, the "parallel synchronous slave interface (PSSI)". We would like to use this for a fast host-to-host communication. But this interface seem so new, we could only find register description in the RM0432 Reference manual. Are there any code example or app-notes for PSSI host-to-host communication?Thanks.

I am new to stellar MCUs. Please share information on how to get the SDK for stellar P series or G series MCU. Which IDE is used? Is there any RTOS support especially FreeRTOS support?

Hi expert,I am using Stellar SR6 P7 line, e.g. SR6P7C8. According to the SDK there is RAM and System RAM reset operation when system boot,/* Initialize memories protected by ECC */ bl _raminit bl _sysraminitI want to get more information about clearing memories for ECC. Why these step are needed? Is this for DAN-0055942? Thanks.

STM32 only connect VCC and UART2. Can it download programs with ISP(UART2 PA2-3)?​

I am using UART over RS-485 on an STM32MP153AAB3.The communication fails because the actual baudrate is off from the specified baudrate. With a specified baudrate of 9600 Bits/s, I am getting an actual baudrate of 9970 Bits/s, as you can see here (time per Bit is 100.3µs instead of 104µs): Changing the baudrate to 115200 Bits/s results in a time per Bit of 8.33µs, i. e. 120000 Bits/s: I set the USART2,4 Clock in the .ioc file to 64 MHz and chose PCLK1 as the source.The value in the BRR register is 0x1A0B which, if I understand it correctly, should correspond to a value for USARTDIV of 416, giving a baudrate of 9615 Bits/s (64,000,000/(16*416) = 9615). My settings are as follows:static void MX_UART4_Init(void) { huart4.Instance = UART4; huart4.Init.BaudRate = 9600; huart4.Init.WordLength = UART_WORDLENGTH_8B; huart4.Init.StopBits = UART_STOPBITS_1; huart4.Init.Parity = UART_PARITY_NONE; huart4.Init.Mode = UART_MODE_TX_RX; huart4.Init.HwFlowCtl = UART_HWCONTROL_RTS; hua
