I have a flexButton in a View, and I want to execute different functions depending on whether the button is PRESSED, RELEASED, or CANCEL.I know you can create interaction in TouchGFX Designer, but you can only call a virtual function on click. Is there a way to, for instance, enable the clickListener Mixin to read the event that has fired the callback from that specific button?I need to read this event within the view and relative to my button.Is there a way, or do I have to create a custom widget?

I am developing a multi-node system (16 nodes) based on the STM32G0C1MET6. During normal operation, all nodes communicate at 500k (Standard CAN). To perform a firmware update, the Master initiates the following transition sequence: Reconfiguration: The Master sends a global command. All nodes switch their FDCAN configuration to 250k (CAN FD) and enter Listen-Only Mode. Trigger: The Master then sends a specific SDO command to a single target node to trigger a jump to the System Bootloader (System Memory). Reflash: Once in Bootloader mode, the target node is expected to respond via FDCAN1 (as per AN2606/AN5405) to begin the reflash process. The Master repeats this node-by-node. The Issue: While most nodes perform the jump and reflash successfully, some specific units enter the bootloader (confirmed by status LEDs) but never respond to CAN messages. These units appear "deaf" to the Master's CAN FD frames at 250k. Environment: MCU: STM32G0C1MET6 Interface: FDCAN1 (Pins: PD0/PD1) Trans

I am using NUCLEO-STM32WBA25CE1. I created STM32CubeMX project for this board. I activated RF, WPAN, RTC. I configured a wakeup every 10 seconds and set up a task for the sequencer to toggle the LED. The LED pin is correctly configured. I can toggle the LED before the main loop starts. But in the task LED toggling is not working. How should i configure GPIO and anything else to get LED working?I am using STM32CubeMX 6.17.0 and STM32CubeIDE 2.1.1 versions.Moreover, I try to use USART1 or LPUART1 for debugging. Before the MCU goes into low power mode, i can output the message to the terminal. But after the low power mode it stops working.

HiWhen I attempt to install the 1.2.1 version of STM32CubeMonitor-Power on Ubuntu Linux, I encounter a "java.lang.ArrayIndexOutOfBoundsException". I saw some posts about problems with files on the server, but they are quite old, and I have a problem with today's download. Can someone help me with this problem?

Good day. I am using STM32WL31 on a custom board.DeepStop mode entry works correctly, but wakeup from PA0 (WakeUp pin) is not reliable or does not work. I used the example code in project:STM32Cube_FW_WL3_V1.3.1\Projects\NUCLEO-WL33CC\Examples\PWR\PWR_DEEPSTOPThe same code I use in my custom board works correctly on NUCLEO-WL33CC2 board (I have tested succefull the code on the NUCLEO-WL33CC2). In my opinion the difference from my custom bord + my code and the NUCLEO-WL33CC2 is the microcontroller; the NUCLEO-WL33CC2 mount the STM32WL33, my board mount the STM32WL31. Code sequence foe enter in deep stop:1. Enable wakeup pin (PA0, PA11 used as wakeup pins are connected by a button to GND). Internal pull-up enabled using LL_PWR_EnableGPIOPullUp on PA0 e PA112. Clear WUF flags3. Enter DeepStop When I press PA0 or PA11 buttons the MCU does not resume execution OR behaves inconsistently, it look like as the micro is in an undefined state.After programmed the micro it seam

Good day,I have a simple custom board with a STM32WL31 that needs to cyclically enter DEEPSTOP mode and then wake by means of RTC internal wakeup. It seems the device enters DEEPSTOP, but does not wake from it. Basic setup:Clocked from HSI, RTC clocked from LSE with 32kHz xtal.SMPS not implemented.Basic project generated with STM32CubeMX 6.16.0 with MCU Package for STM32WL3 Series 1.3.0 installed.IWDT activeMR_SUBG radio not yet implemented I can confirm RTC runs, RTC interrupt occurs every 1s, and HAL_PWR_EnterSLEEPMode() behaves correctly. However, when I enter DEEPSTOP with the sequence below, then the code never gets to HAL_ResumeTick() (reset after a few seconds by IWDT): PWR_DEEPSTOPTypeDef sConfigDEEPSTOP; sConfigDEEPSTOP.deepStopMode = PWR_DEEPSTOP_WITH_SLOW_CLOCK_ON; HAL_PWR_ConfigDEEPSTOP(&sConfigDEEPSTOP); HAL_SuspendTick(); HAL_PWR_EnterDEEPSTOPMode(); HAL_ResumeTick(); Below is a reg dump of possible relevant registers just before calling&

Would it be possible to use a Time-of-flight sensor to measure water level in a pipe?The pipe is vertical with a diameter of 50 or 75 mm and a height  of 800 mm. At bottom there is a 90 degree bend. Sensor should be at top looking down the pipe. I assume that best sensor would be VL53L4CD since it has smallest field of view. Would reflection from pipe walls disturb measurements?   

Hello all! I need some rubber ducking help here. I have got hold of a B-U585I-IOT02A dev board, where I'm trying to get learn and get to know the STM32 family. I have got a lot of things working, but the ADC1 is giving me a hard time: Here is my MX config: IN1 enabled, and expecting the data to be stored in the DR register. PC0 is selected as ADC1_IN1: Global interrupts are enabled: So far, so good( I think ). my application code: /* Running in my main while(1) loop */ // Other stuff before here if (StartConv) { if (HAL_ADC_Start_IT(&hadc1) != HAL_OK) { /* Start Conversation Error */ Error_Handler(); } StartConv = 0; } HAL_Delay(10); And when above is executed, I can see that I'm getting a interrupt and call to my own ConversionCallback function: void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* AdcHandle) { /* Get the converted value of regular channel */ adc_raw = HAL_ADC_GetValue(AdcHandle); printf("ADC Raw Value: %lu\r\n", adc_raw); // Retrigger convertion

Hello I've been trying to recreate the DCMIPP_SnapshotDecimation example with STM32CubeIDE, I have been running into several issues. I have solved most of them, I am encountering a memory error while debugging my code. I was able to flash and debug the original example successfully on the STM32N6570-DK. However, when I try to read a value from the AXISRAM address (0x34200000), it fails: (address does not exist and unable to reconnect to target device). AXISRAM3 which it should be the address 0x3420000 is activated and initialized in the main. Initialization of  the signal processor and starting the DCMIPP pipeline was passed without any problem:if( ISP_Init(&hcamera_isp, &hdcmipp, 0, &appliHelpers, ISP_IQParamCacheInit[0] ) != ISP_OK ) { Error_Handler(); } if( HAL_DCMIPP_CSI_PIPE_Start(&hdcmipp, DCMIPP_PIPE1, DCMIPP_VIRTUAL_CHANNEL0, BUFFER_ADDRESS, DCMIPP_MODE_CONTINUOUS ) != HAL_OK ) { Error_Handler(); }But, trying to access the buffer addr

Hello,I'm working on a projet where I need to drive 4 (or 2 x 4) GPIO at the same time with high speed on the STM32U545RE.I'm trying to use the DualQuad SPI (with OSPI) but I can't have the clock working...At first I tried to write a code with a send only type of frame (with no instruction and no address) but nothing was working.Now I tried to use the example code from a STM32L5 but nothing seem to be working either. Can you if someone already tried to do that ? BR,Loïc

I use STM32U5A9J-DK to plot a graph containing a series of V-I data. I have tried static graph widget and was succeed, but it somewhere doesn't meet my need: the label can only show int, if  x data range is -0.6~0.6V, I can only scale them to -600~600, in mV unit, (but I want to show unit in V); besides, my data sequences may have the same x value with different y, e.g. (-0.6,2) (-0.2,5) (0,3) (-0.2,2) (-0.6,1), data like this can't be plotted on static graph, it only accepts monotonous x value. I need my graph showing the original data points (need no scaling) and allowing same x value with different y values, Any other way I can build a graph fitting my requirement? I use touchgfx 4.26.1, seems no canvas function ?!I mean like drawing the plot below, with a lots of on the same graph, and allow me to active/inactive the plot, each plot is a regression 

Hi, My projet has been working fine until the last week or so where I can no longer debug. When I press F5 I get a "Missing CMSIS_PACK_ROOT" with a notification toast message of "gdb is not running".Nothing has changed in terms of project settings, launch.json, etc. as far as I'm aware.

If the STM32H743IIK6 is clocked by an external 25MHz clock generator, but we still aim for minimum current consumption until a wake-up is required, what is the lowest achievable current draw assuming everything is powered down except for the external oscillator? Thanx,Eli. 

In the last weeks, I was working on running W25Q256 nor flash chip from vendor Winbond with STM32F746 MCU on a custom board. My guideline in this road is ST's how to run QSPI flash video tutorial (5-part video) and of course some genius guys in the community who's helped me a lot to rewrite the functions of QSPI flash (Init, Erase, Write, Memory-mapped). So far functions tested in the Main.c and I can read the pre-written data on the memory. The next step is to generate (.stldr) external loader file and modify Flash.ld file.according to the video tutorial, I added Loader_Src.c, dev_inf.c, and dev_inf.h files to the workspace but there is a little confusion about flash.ld file that contains memory definitions and all other data and text stuff to assign to specific memory (>FLASH, >RAM, >QUADSPI).for the point of concern, I use STM32F746 with IS42S32400F SD-RAM connected with 2-banks to MCU and of-course W25Q256 NOR-FLASH.how to modify flash.ld file to my specific condition and

The graphical representation shows an internal op-amp amplifying the signal entering the comparator's positive input.However, the STSPIN32G4 positive input comparator cannot be an op-amp output unfortunately and is limited to op-amp positive inputs - see Ref. Manual RM0440 ver 9 (Figure 168).This is misleading, because only non-amplified signals gets to the positive input of the comparator.

I need to implement a protocol using 11110000 as preamble. The protocol is 2-FSK 868.1 MHz, +/-35kHz, 25kbps. According to RM0511 STM32WL33 only supports 01010101 or 10101010 as preamble for 2-FSK. Is it feasible to use the STM32WL33? I am planning to use direct buffer mode.

The board I am using is NUCLEO-H7S3 and I have encountered the following issuesI want to perform continuous and large data sampling using ADC+DMA, but when the collected value reaches 10000, the subsequent values become 0. When I modify the number of collected values to 50000, it stops at 17231 and the subsequent values remain 0. At this point, I am connecting the ADC pin to the 3.3V on the board. I'm not sure where the settings went wrong, please help me.Thank you.

Hello,I am working on a project where I need to both read and write regularly into the STM32 flash memory. I have some concerns and questions regarding its endurance.First off, I posted a question not long ago about writing to FLASH using ST EEPROM library. I was wondering why upon writing to a variable, it did not effectively write it into flash. This is essentially due to how the library itself works. Hence why I can not really use it to manage flash wearing, because I need the writing to happen precisely when I call a write function due to the fact that my product can be power off at any moment.So going back to the reference manual RM0456, I came upon section 7.3.8 which states:"Each flash memory page can be written and erased 10 000 or 100 000 times. A maximum of32 pages (256 Kbytes) per bank feature this increased endurance of 100 kcycles. Thisenhanced endurance can be used for data storage that usually needs more intensivecycling capability than code storage.Any flash page can be

Hi,I want to create a pin-compatible board to X-NUCLEO-SRC1M1 to further explore USB-C charging, is there a STEP or DXF file available for this or any other X-NUCLEO board that has both the ST Morpho and Arduino UNO R3 connectors please?Kind regards,Al

Created a STM32H743II prj with I2S2 enabled, half-duplex slave receive mode, and DMA1 S0 bounded to SPI2_RX, to work with an ADC in master mode. Can't get data from the ADC ( DMA linked mem area always zero ), while my oscillograph can properly decode the ADC I2S data output pin ( CK & WS pin also connected between the ADC board and the H743 board, and the oscillograph ). In cube, the SDI pin is mapped to SPI2_MISO, PB14. But as a slave, shouldn't the correct SDI pin map to SPI2_MOSI, PB15? So I modified the cubeMX generated code manually, by changing PB14 to PB15 in the I2S2 GPIO initialization sector, and it worked, the DMA linked mem area shows the same value on my oscillograph. Is this a cubeMX bug?
