I'm in trouble using dll with c# for using the mailbox.Can someone help me?Please @Ulysses HERNIOSUS , my friend, help me! I'm pain too! Here is the code: private void TxRxNBytes_Click(object sender, EventArgs e) {//This is a button click event handler    sbyte[] rx = new sbyte[512];    //Here following is the reversed uid byte sequence compared to the one reported from software ST25PC-NFC    byte[] uid = [0x61, 0x92, 0x74, 0xD0, 0x01, 0x24, 0x02, 0xE0];        ee = ST25R391x_Dll.iso15693Select(Handle, uid);    // ee=NoError    sbyte[] tx = { 0x10 , unchecked((sbyte)0xAA) , 0x02 , 0x06 , 0x01 , 0x02 , 0x03 , 0x04 , 0x05 , 0x06 };    ee = ST25R391x_Dll.iso15693TxRxNBytes(Handle, tx, 10, rx, ref uRxDim, 1);    //    ee=NoError... // ... but microcontroller hosting ST25DV04K doesn't receve the GPO signaling.//  

[EDIT 03/04/25 09:15:35 AM] Well, it appears that, as usual, the real issue was sitting right in front of the keyboard… and could have been solved with a good old ‘Read The Freaking Manual.’ My deepest apologies for this classic case of user error! :grinning_face_with_sweat:Sensor_ID inversion (0x01 and 0x02) I'm struggling with programming the ISM330DHCX on a sony spresense.

Would it be possible to connect and send sensor data to a Pi Pico W from the STEVAL-MKBOXPRO? I’m looking for a way to connect them together via Bluetooth but a wired connection would be alright too. I have connected a Pico to the sensortile box via Bluetooth already but I do not know how I can gather sensor data from this. Also is there any official or unofficial documentation on any similar endeavors? I’ve found this link which seems promising but the implementation is not very detailed https://community.st.com/t5/mems-and-sensors/how-to-create-a-custom-gaming-controller-using-sensortile-box/ta-p/597296. 

Hello,I have a GPIO pin that is owned and used by the M4, i.e. Pin Context Assignment.  But on power-up, I'd like the M7 to do some work with it, toggle the state, before it starts the M4.  Is it possible for the M7 to programmatically take ownership of the GPIO pin, then transfer it back to the M4 just before it starts the M4?Regards,Robert 

Hello, I am working on a project that includes HTTPS communication, peripheral communication via LIN, and a graphical user interface. I am using the STM32H745I_DISCO board. I have already tested and successfully implemented the HTTPS and LIN parts.Yesterday, I started investigating how to get the GUI up and running. I downloaded an image with TOUCHGFX 4.24.2, and it displayed correctly. Then, I followed the example from this link to configure it via CubeMX, but without success. The strange thing is that when I tried downloading an image or a demo to the board again using TOUCHGFX 4.24.2, artifacts started appearing. I tried erasing all the memory areas visible in STM32CubeProgrammer, but after loading an image or demo, the artifacts persisted. The last thing I tried was loading a blank GUI. I am attaching an image of what appears on the screen: vertical red stripes and pixels randomly turning on and off in red. It seems like a RAM read issue, but I can't understand why it per

Hello ST,I'm developing a USB CDC communication project on an STM32L452RE microcontroller using STM32CubeIDE.I can successfully receive data from a PC using the Hercules SETUP utility by HW-group.com.I'm facing a challenge with transmitting data back to the PC using the CDC_Transmit_FS function.Environment:MCU: STM32L452REIDE: STM32CubeIDECUBEMX: STM32CubeL4 Firmware Package V1.18.1USB Configuration: Configured as a CDC Virtual COM PortOS: Windows 11USB Interface: Hercules 3.2.8Issue Description: Data reception from the PC works flawlessly. However, when attempting to transmit data back using CDC_Transmit_FS, the function seems to never complete. The code gets indefinitely stuck waiting for hcdc->TxState to reset to 0, which, based on my understanding, should happen via an interrupt once the transmission completes.Troubleshooting Done:Create a new ST board project using this video USB tutorial:https://www.youtube.com/watch?v=92A98iEFmaA&t=212sConfir

Hi,I'm developing a bare-metal project with the SR5E1Ex (E3 and E7), and need to determine the current core ID at run-time.Could you please confirm if there are any registers that can be read to determine the current core ID? The only multicore examples I can find for the SR5E1Ex chips use different restart locations to determine the current running core, but if there are any registers that can be read with the core ID, that would be preferable.Regards,Steven Daglish

So I'm having this issue with a Nucleo STM32H563ZI board regarding the USART3 that connects to the VCP ST-Link port.If I enable the USART3 at 115200 baud rate, and keep all the default parameters and, in the clock configuration, if I do not change any clock parameters, except to configure the HCLK to 250Mhz, then the USART3 Clock Mux will use PCLK1 and also will output a clock frequency of 250Mhz.So basically all defaults without too much changes except the HCLK.In this situation, the USART3 works just fine, meaning that I can see correctly the data that is output by the USART with a terminal program. So far so good.Nevertheless if I change the main clock source to the 24Mhz crystal, hence use the HSE and still keeping the HCLK at 250Mhz, the USART Clock Mux will still also be at 250MHz (still using PCLK1), BUT this time the USART output is just garbage meaning that the baudrate calculation is just wrong.If I drop the USART clock mux to 4Mhz, for example everything just starts to work

Hello ST Community,I was successfully working with my STM32WB55RG Nucleo-64 and had FUS (Firmware Upgrade Service) and the BLE stack properly uploaded and running initially. However, after attempting to modify some register values in the Option Bytes, I encountered a serious issue where FUS and the wireless stack appear to be corrupted.Now, when I try to upgrade or reinstall the BLE stack, I am facing errors, and FUS is no longer functioning properly. FUS Version is now corrupted and shows invalid values (attached screenshot).FUS upgrade is failing – attempting to reflash FUS results in errors.BLE stack cannot be reinstalled due to the corrupted FUS state.Attempts to start FUS fail with FUS_STATE_ERR_UNKNOWN.Steps Tried to Fix the Issue:1. Attempted to Reinstall the BLE Stack (stm32wb5x_BLE_Stack_full_fw.bin) → Failed due to FUS corruption.2. Tried Deleting the Wireless Stack in STM32CubeProgrammer →  Did not resolve the issue.3. Performed a Full Chip Erase → FUS corrupt

Could you tell me the differences between the IIS2DLPC and LIS2DW12?According to the reference URL, are there any differences between these two devices other than product longevity and guaranteed parameter values? I am particularly interested in whether there are any differences at the wafer level.From a business continuity perspective, we would like to evaluate both the IIS2DLPC and LIS2DW12. However, it would be a waste to evaluate the same hardware twice. If it can be confirmed that there are no differences, we would like to evaluate only the LIS2DW12. Reference URL:https://community.st.com/t5/mems-sensors/iis2dlpc-vs-lis2dw12/m-p/179418

Hi all,I'm trying to understand how can I use this ST lib to activated interrupt if accelerometer data ready. I already use this lib but I don't use interrupt mode, right now I'd like to try it.So if I understand well I have to use int32_t lsm6dso32_pin_int1_route_set(const stmdev_ctx_t *ctx, lsm6dso32_pin_int1_route_t *val) I've find it in the datasheet :. Write INT1_CTRL = 01h // Accelerometer data-ready interrupt on INT1 in Startup sequence part 4.1, so if I want to activate the interrupt I have to write 0x01 in INT1_CTRL register, but I'm little lost to how to use typedef struct { lsm6dso32_int1_ctrl_t int1_ctrl; lsm6dso32_md1_cfg_t md1_cfg; lsm6dso32_emb_func_int1_t emb_func_int1; lsm6dso32_fsm_int1_a_t fsm_int1_a; lsm6dso32_fsm_int1_b_t fsm_int1_b; } lsm6dso32_pin_int1_route_t; and typedef struct { #if DRV_BYTE_ORDER == DRV_LITTLE_ENDIAN uint8_t int1_drdy_xl : 1; uint8_t int1_drdy_g : 1; uint8_t int1_boot : 1; uint8_t int1_fifo_th : 1; uint8_t int1_fifo_

I downloaded Cube Power Monitor and am trying to use it to connect to the LPM01A. I have downloaded and installed the W8 version of the virtual com port driver. I can select the board in the drop down menu, but when I hit "Take Control", a dialog box pops up with the message `error pwr get`. When I hit okay, another pops up with the message `Get current range command failed` with another message below it `ERROR TIMEOUT`. Hitting ok again gives yet another dialog box with the message `Board has been released due to connection issue. Please unplug and plug the board`. I've tried unplugging and plugging it back in and the same thing happens. I am currently on Windows 11, but I've tried on a different windows 10 machine and the result was exactly the same. Any help would be appreciated. Please also take a look at my other question for something that might be related... having lots of issues with this board so far...

Hello,I have a STM32F777 with ST7789 Display controller over SPI.To write the Framebuffer i have the following code: void TouchGFXHAL::flushFrameBuffer(const touchgfx::Rect& rect) { // Get Framebuffer Address uint8_t* frameBufferAddress = (uint8_t*)HAL::lockFrameBuffer(); // Calc start address uint8_t* fbPtr = advanceFrameBufferToRect(frameBufferAddress, rect // Set window DisplaySetWindow(rect.x, rect.y, rect.width, rect.height); // Start DMA Transfer DisplaySendDataDMA(fbPtr, rect.width * rect.height * 2); // Wait for DMA Transfer end if (osSemaphoreWait(DisplayTransferSemHandle, osWaitForever) == pdTRUE) { HAL::unlockFrameBuffer(); HAL::flushFrameBuffer(rect); } } I can't build the code because the function advanceFrameBufferToRect() is defined as inline but without implementation in the header. The implementation in the source file is not accesible with the inline statement.How can I fix this error? Is the code above correct?Thanks for your r

Hi,I have a c++ file with a table of utf16 c style strings encoded as utf16. I need this file to be encoded as utf16 for the compiler to understand correctly the 'special' characters. In IAR, it was super easy as the compiler could read both utf8 and utf16 files.It seems however that cubeIDE only handles utf8 encoding. Is that true? Is there a work around? Moving my table from utf16 to utf8 would really annoy me…Thanks in advance  

Hi,Release notes for STM32MPU ecosystem v4.0.0 mention “Add support of Firmware Update feature�?. Is there anymore information available on this feature? Or is it utilising an existing Yocto swupdate layer?Any additional information would be appreciated. Thanks

Hi, I was curious on the operation of the tearDownScreen function in regards to local variables created in the screen views hpp file. If I create a Struct A in screenview, and pass it by reference to the presenter then to the model, is this recommended against since tearDownScreen would get rid of the struct A? Is it recommended to dynamically create the Struct A in the screen view then delete it in the tear down screen function after sending it to the model?

Hi,I am using STM32G0B1VET6 on my custom board. I want a delay of 0.2 and 0.3us. Hence I have used timer 6 to achieve this delay. But my program leads to crash when API - HAL_TIM_Base_Start_IT(&htim6) is executed.My settings for Timer 6 are as follows: My clock configuration is as given below:Generated code:static void MX_TIM6_Init(void){ /* USER CODE BEGIN TIM6_Init 0 */ /* USER CODE END TIM6_Init 0 */ TIM_MasterConfigTypeDef sMasterConfig = {0}; /* USER CODE BEGIN TIM6_Init 1 */ /* USER CODE END TIM6_Init 1 */htim6.Instance = TIM6;htim6.Init.Prescaler = 0;htim6.Init.CounterMode = TIM_COUNTERMODE_UP;htim6.Init.Period = 13;htim6.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE;if (HAL_TIM_Base_Init(&htim6) != HAL_OK){Error_Handler();}sMasterConfig.MasterOutputTrigger = TIM_TRGO_RESET;sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;if (HAL_TIMEx_MasterConfigSynchronization(&htim6, &sMasterConfig) != HAL_OK){Error_Hand

This might be *** question but I have to ask as as I'm a biginner... I want to interface ST25r3916 with STM32F072xx without using BSP package and HAL. I'm currently using bare metal embedded c. I've been trying to change rfal_Platform.h file which I think I got right. is it possible to write the code from scratch since the example code is generated by MXCube??

Hi!I'm creating an i2c-slave using a stm32g0-series. There are two types of messages that need to be supported, a write-then-read, and a write-only.The write-then-read starts with a write-message of a register address of the slave device (1 byte). This is followed by a repeated start condition where the master writes the data to the register address.     The write-only starts in the same manner, but in addition to the register-address, a number of bytes (depending on the register) are also written to the slave. IFAIK these are fairly common ways to do reads and writes. The write-then-read messages work fine with the use of HAL_I2C_Slave_Seq_Receive_IT (receive one byte) and HAL_I2C_Slave_Seq_Transmit_IT (transmit n bytes). My problem arises when the first message (write) can either be one byte (write-then-read) or multiple bytes (write-only). The way I see it, I either have to detect if the repeated start condition has happened (one byte has

Hi All!I have an application where I am designing a PCB for an STM32 MCU. However it requires a faster ADC than the integrated one. I am thinking about using the AD9057 by analog devices, using parallel interface. I want to ideally read as fast as possible each sample, and transfer data to memory using DMA. My question then is, what is the fastest/most elegant way of doing this, and what is the easiest way of doing this? Could one for example use PA0 to PA7 as GPIO inputs and read them simultaneously and transfer the data using DMA or CPU at 20 MSPS? Is is fast enough? I am open to any suggestions! I would love examples too!Could one use FMC? How would one configure it?Best regardsNOTE: I am trying to avoid using FPGA

Hi, I have an application that should trigger an interrupt on a falling level signal. For argument sake, let's say that I expect it to trigger about once a second. Now, when I run my code, it triggers(the EXTI12 ISR) more like 30 times per second. I have measured the level signal, and it is flat but the ISR for some reason still triggers. Attached is the scope plot of my level signal. I have a Debug IO PIN toggling plot as well. you can see, I ran this over 3s and my scope had 3 captures, from my analogy this means the level signal cannot be the cause ?. This is my code in the ISR(I have a bunch of other ISR's in here)Continued: then I exit: Detail: I do trigger another ISR using Software I don't know if this can have an effect .The code for this is below:  My ISR subroutine consists of multiple IF statements for me to run specific code when other Level Signals go Low/High. Here is a debug IO Pin toggling, Which is how I know

Hello,In previous touchgfx releases, we all know that partial framebuffer is limited to 20 lines. Now with touchgfx 4.25, is it possible to increase it? If yes, how can I do it?In addition, I tried to increase "Block Size" in .ioc file, however it still sends only 20 lines. It does not use remaining block size. I need a clear example.Thanks!
