Hi ST community i just searched the GUI for EV-VNF9Q20F but could not find it. Please tell us where can i get suitable GUI. and also i'm really glad if you could check the availability of SPC582B against EV-VNF9Q20F.

Hello all,I'm working on an embedded project based on an STM32F030K6T6 microcontroller.The MCU is connected to an Adafruit TFT display with an integrated resistive touchscreen. The display is driven via SPI using the ILI9341 controller, while the touchscreen is interfaced using four wires (X+, X−, Y+, Y−).The resistive touchscreen is read by dynamically configuring the GPIO pins and performing ADC measurements to retrieve raw X and Y coordinates. These raw values are then calibrated and mapped into screen coordinates to detect user interaction with the UI.The graphical interface consists of four blocks:- RELAY_1_ON- RELAY_2_ON- RELAY_3_ON- RELAY_4_ONEach block behaves like a button. When the user touches a block:- the corresponding GPIO is set HIGH to drive a MOSFET connected to a relay.When the same block is touched again:- the GPIO is set LOW, turning the relay OFF.To handle touch interaction corr

(and why is this a problem?)It looks like the backup ram can not be called through unaligned access on my STM32U585. The mighty internet says that this should not be completely unexpected since it is basically a peripheral and no standard Ram.I have set up the BKPSRAM in the linker file like this:#include "partition.h" /* Entry Point */ ENTRY(Reset_Handler) /* Highest address of the user mode stack */ _estack = ORIGIN(RAM) + LENGTH(RAM); /* end of "RAM" Ram type memory */ _Min_Heap_Size = 0x000 ; /* required amount of heap */ _Min_Stack_Size = 0x800 ; /* required amount of stac

I could able to find only .hex output file for this demo app. Where is the source code ?

Hello,  I am currently using the IIS2MDC in my design with the following configuration: As you can see, I am not using the INT/DRDY pin, so it is left unconnected. However, in idle mode, I am measuring an abnormal current consumption of around 400 µA. I noticed that this extra consumption disappears completely when the INT/DRDY pin is tied to GND via a pull-down resistor.The datasheet states that this pin is configured as a High-Z output by default. I do not understand how this floating setup could cause such a high leakage current. Furthermore, I could not find any specific hardware desi

Hi communityI found a missconfiguration in CubeMX while using a MCU TFT with FMC.Description:Device: STM32N6 (STM32N645B0HxQ) / Cortex-M55CubeMX Version: v6.17.0Peripheral: FMC, LCD Interface, 16-bit data width, A16 as RS/DC (Register Select)Symptom: A single WriteCommand() call (one STRH instruction to 0x60000000) produces 3 WR pulses on the oscilloscope instead of 1. The LCD display remains gray despite a correct initialization sequence. All FMC timing parameters and Write FIFO settings were verified and are not the cause.Root Cause: The Cortex-M55 (ARMv8-M) treats 0x60000000 as Normal Memory by default. This allows the CPU to merge and reorder 16-bit write accesses into 64-bit bursts, resulting in multiple spurious W

I am currently working on a resolver ad2s1210. I have selected the required pins generated the code and entered my code and now it does not seems to be running. As the screen shows this Kindly let me know whats seems to be the issue here and how to rectify it.

I am devoloping a low-power motion detector device using the STM32L071 mcu.The PIR sensor wakes up the system through wake-up pin, and after completing the RF packet transmission, the system goes back to sleep. In other words, I have a system that continuously switches between standby and run modes.How should I implement the watchdog in such a system ?I don't want the watchdog to keep counting while the MCU is in standby mode. I only it to run during run mode.My code like this (bare metal): int main(void) { /* USER CODE BEGIN 1 */ config_getresetflags(); /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* USER CODE BEGIN Init */ /* USER CODE END Init */ /* Configure the system clock */ SystemClock_Config(); /* USER CODE BEGIN

Hello,In this file, the line:USBx_HC((uint32_t)ch_num)->HCSPLT |= USB_OTG_HCSPLT_XACTPOS_Pos;wrongly alters bits 1 to 3 of register HCSPLTThat can be fixed simply by removing this line, since middle payload is encoded by bits 00 in the XACTPOS field. 

Hello, I purchased an STLINK-V3PWR from Mouser. When I tried to use it, STM32CubeIDE 2.1.1 suggested updating the firmware. This failed, and the STLINK-V3PWR appears to be unusable (bricked). What can I do? Return the device for a refund/replacement? Or is there a way to re-flash the firmware using an STLINK-V3SET? If it is possible to restore the firmware by re-flashing it, where can I find the correct firmware? Kind regards, Jack.

Hello everyone,My apologies if this is in the wrong forum. I have a STEVAL-BMS114TX evaluation board and I'm wondering what to do with unmounted cells, since my pack is 5s. The datasheet for the L99BM114 says to short the unused PCB connectors together, but this definitely cannot be done on its corresponding evaluation board. Does anybody have any advice on how to move forward with this? The STEVAL-BMS114TX datasheet says that it can manage from 4 to 14 battery cells, but doesn't provide much clarity on unmounted cells.Thank you for the help. 

Hello everyone,We are currently designing a decentralized Battery Management System (BMS) node for our Formula SAE electric car. We selected the L99BM114 due to its robustness in automotive environments and high measurement accuracy.Our architecture requires this specific node to monitor a 5-series (5S) cell module. Since the L99BM114 supports up to 14 series cells, we will have 9 unused channels.While reviewing Section 6.8 of the datasheet (Unmounted cells), the exact hardware implementation for our case felt a bit ambiguous. We want to ensure our schematic doesn't trigger false internal diagnostics, such as Cell Open Wire or Balancing Short/Open.Could anyone clarify the recommended wiring for the unused pins in a 5S configuration? Specifically:Voltage Sense Pins (C6 to C14): Should all these unused inputs be shorted together and tied to the highest active potential (C5)?

Hi !I've using TouchGFX Designer for a while, only using Simulator project (which Board setting is PC) for sfx evaluation and learning. And I wanna try to flash my previous project running on a real microcontroller board like F429 discovery board.Here's my question: How to migrate my previous PC Simulator project to new CubeMX project based on real board project?I tried to find related settings in TouchGFX but failed. Is it the only way to migrate my previous ui into new project by doing all the steps in the new TouchGFX project？Thanks !

Hi ST Support Team,  #1 Demo provided by ST for STM32H7B3I-EVAL board is working on Windows Simulator.   But it is not working for Target (STM32H7B3I-EVAL board.)  #2 Does code generated by TouchGFX designer will run on Target board without any code changes on target (STM32H7B3I-EVAL).Please help me to resolve this issue.  Regards,Tejas

I ported PPSSPP 1.20.3 to run on the STM32MP257D platform.With the GLES backend, everything looks fine and normal games run without issues. But when I try heavier 3D games like Tekken 6, it gets extremely choppy – single-core CPU usage stays around 95%.Then I tried switching to Vulkan. At first, the emulator crashed on startup. I debugged it by adding some print statements and found that a function call was returning an incorrect value – which shouldn't happen according to the Vulkan spec. Because of that, another function (vkCreateSwapchainKHR) ended up failing. 1) PPSSPP Crash Log:Spoiler (Highlight to read)

Hi,I created a project in STM32CubeMX 6.17.0 targeting the NUCLEO-G491RE and successfully generated the code. I then imported the project into STM32CubeIDE 2.1.1 and as far as I can tell it looks ok. The only apparent issue was that when I clicked on the .ioc file I thought that the STM32CubeMX project was supposed to open inside STM32CubeIDE but instead I get an error saying:So that's one issue. But when I come to build the project in STM32CubeIDE there is no Build All (CMD+B) option available, or indeed any other build options available.

hi, I created a project by the MCSDK, i tried running it as a C++ project, but im getting an error compilation that i cant solve:   ../../MCSDK_v6.4.2-Full/MotorControl/MCSDK/MCLib/Any/Inc/revup_ctrl.h: In function 'void RUC_Stop(RevUpCtrl_Handle_t*)': ../../Inc/mc_type.h:77:32: error: invalid conversion from 'void*' to 'RevUpCtrl_PhaseParams_t*' [-fpermissive] 77 | #define MC_NULL (void *)(0x0) | ^ | | | void*     it seems that there is a wrong casting issue. I tried to solve it in some fifferent wauys like: pHandle->pCurrentPhaseParams = (RevUpCtrl_PhaseParams_t*)(malloc(MC_NULL)); or pHandle->pCurrentPhaseParams = static_cast<RevUpCtrl_PhaseParams_t *>malloc(sizeof(MC_NULL));  

Good afternoon,First post here, so aologies for any ignorance.I am trying to combine the subghz radio feature of WL55JC1 and the ST60 high frequency communication Full Duplex UART bridge.Ideally, I would be switching between these two functions.I have ported the ST60 example to the WL55JC1 dev board, and can get both running independently.But my problems arise because the subghz radio example uses the STM32 Sequencer utility, while the ST60 doesn't.When I try to integrate the sequencer into the ST60 code, it seems like the I2C comm/config channel for ST60 stops working.Does anyone have any guidance/direction in this area?Appreciate your time.

 Hi everyone,I am working on an STM32H523 MCU and I have recently observed some strange behavior regarding the PB14 and PC9 pins. I have the following setup:PB14 is configured as input (I use this for the TIM2_CH2 alternate function, but this does not affect the issue) and is externally pulled up using a 10kOhm resistor.The PC9 pin is configured as output.When the PC9 pin is unset, the PB14 is 3.3V, as expected. But when setting the PC9 pin, the voltage on PB14 drops to only 1.13V.  These pins are otherwise not connected, so 2 seemingly unrelated pins seem to have some dependency within the stm32h523 chip.  Another test was performed by configuring PB14 as output (without pullup). Now, when PC9 is unset and PB14 is set, the voltage on PB14 is 3.30V. When setting PC9, the PB14 voltage drops to 3.26V, which seems related... To make sure it is not caused by our own har

I am using STM32CubeMX 6.16.1 to configure a project for STM32F415.I use the FATFS on SD card and set it up as:According to FATFS documentation (https://elm-chan.org/fsw/ff/doc/config.html#lfn_unicode), the data type TCHAR should translate to char in this case. However, CubeMX generates Middlewares/Third_Party/FatFs/src/ff.h in which TCHAR is defined as WC
