Hey, I am using the RK043FN66HS-CTG LCD touchscreen (480 x 272 resolution) and have used the GT911 drivers found at:GitHub - DiveInEmbedded/GT911-Touch-driver: Simple and ready to use touch driver for Goodix GT911I have a custom STM32H743IIT6 PCB.It is currently recording coordinates incorrectly in the y- axis. Bottom right hand corner should be 480,272 (X,Y) roughly in landscape configuration. I am getting ~440,180.I have gone through the GT911 Register Datasheet but cannot seem to figure out why the readings are still off.Any suggestions why I am getting these issues. I understand the config version register has to be increment by one with each set of GT911 settings. My GT911 Config is here: static uint8_t GT911_Config[] = { 0x89, // Config version 0xE0, 0x01, // X = 480 0x10, 0x01, // Y = 272 0x05, // 5 touch points 0x40, // ModuleSwitch1 (landscape, no flip) 0x20, 0x01, 0x08, 0x28, 0x05, 0x50, 0x3C, 0x0F, 0x05, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

I am using stm32cubeprg-win64-v2-21, and I am experiencing an error.After launching the program and clicking Open File, the Open File window appears briefly, and then the program closes unexpectedly.I uninstalled it and tried using a previous version of STM32CubeProgrammer, but the same issue occurs. Rebooting the laptop does not resolve the problem either.  I have captured a video of the issue and attached it.

I am developing a Battery Management System (BMS) for a hybrid inverter solar panel system. I am using the ADBMS1818 IC as the battery management chip from Analog Devices. Currently, I am looking for a suitable MCU for my system. I found that the CYT2B7 MCU from Cypress Infineon fits my system well. However, during the development process, I need to use an MCU from STMicroelectronics. Could you recommend a series that meets my needs? Below are the specifications of the CYT2B7 Thank you for your assistance.

Title edited to note that this is a clone ST-Link.Using a WeAct mini STM32H723 Core board which seems to be working fine via SWD and a gold STLInkV2 USB stick. (STLinkV2 firmware V2j46S7).Using STM32CubeProgrammer v2.21.0 seems to work ok, connected under SWD, 4kHz, Normal mode, S/w reset, reliable speed, non shared (my usual settings that work with all the other STM32 boards I have).But when I tried the "Full chip erase" (or erase selected sectors), it merely reports erase successful with no errors. However the flash remains unchanged.Using STM32CubeIDE 2.0.0 however, I can successfully download my code to the board (which proves the flash can be erased using the STLinkV2 h/w).Not sure where the problem lies as yet, but have put this issue up here in case others have the same problem with STM32CubeProgrammer.Will post an update here or on the WeAct github site if I make progress to finding why its not working.

I have an STM32H7S78-DK and I have used TouchGFX to create a GUI just fine. I am currently trying to use the fanout or the Arduino headers to communicate through SPI or UART to another board.  The first thing I tried was using the SPI through the fanout board as it's soldered for the SPI4 by default with the fanout board.  I used the female headers on the fanout board that corresponded with MOSI, MISO, etc for the SPI.  I configured SPI4 in STMCubeMX and generated the code in STMCubeIDE.  I just tried to send an array with Hello in the array in the form of hex values.  However, I saw nothing coming out of the pins when I hooked it up to a logic analyzer. I then thought maybe I was using the wrong header and soldered some male pins next to the female pins which said CN12 which corresponded to what it said in the fanout boards documentation. I thought maybe the microbus female headers were not the right ones to use.  Generated all the code and tried again an

Hello Support Team,Good day,For product development, we chose the STM32U585 family, a trust zone-based MCU.

Hello,I'm working with the STM32MP257F-DK using the Yocto Project, and I'm trying to enable I2C in my custom Device Tree.However, I’m facing an issue where the I2C controllers remain stuck because of power-domain pending states.Here is the relevant dmesg output showing the problem:It looks like the D1 power domain never reaches sync_state(), which prevents the I2C drivers from probing correctly.I suspect a configuration issue in the power-domain hierarchy or in my SoC/board Device Tree, but I haven’t found the root cause yet.Could someone help me understand what is missing to properly enable the I2C controllers and bring the D1 power domain out of the pending state?Thanks in advance for your support. 

Hi everyone,I think I’ve messed up my NUCLEO-H755ZIQ board. A few days ago, I accidentally unplugged the board while an active debug session was running. Since then, the board "dies" every time I power it off.To get it back to a working state, I have to follow this tedious process every single time:Set Boot0 to VCC.Connect via STM32CubeProgrammer (Power Down mode).Perform a Full Mass Erase.Disconnect and set Boot0 back to GND.Connect again and flash a simple .elf file (a basic SPI project that toggles an LED) just to verify it's alive.After this, I can debug normally in CubeIDE—until I power cycle the board again.This was manageable until I started working on a Bootloader project. Today, it took me all morning to recover the board because the bootloader logic seems to interfere with my "recovery" steps.I’ve already tried messing with Option Bytes and performing several mass erases, but the issue persists. It feels like the flash or the option bytes are stuck in a state that prevents a

Hello everybody.On STM32MP2, is it possible to operate only the M33 like a microcontroller, without booting the A35? Also, if only the M33 is operated, can major peripherals such as I2C and Ethernet be controlled from the M33? (I assume that PCIe would be difficult...)

Title edited to flag that this relates to a Black Pill & Clone ST-Link After much too much time searching and following advice from for the most part, outdated forum posts I have been unable to resolve my issue with win 11.I have a windows 11 machine (Microsoft Surface) up to date as of 28th January 26.ST Link Utility installed and wokingStCubeProgrammer 2.21.0 and working (apart from not seeing the STLink v2.0 hardware).Both installed as Administrator.Cube Programmer however refuses to acknowledge the STLink v2 when connected even though the driver reports it is working and indeed it shows up in Device Manager. I did try reinstalling and the other common resolve I see is to switch to Shared Enabled in the right hand panel.The odd bit is it just works on my Mac M2 Tahoma without any issues and displays the correct serial numberI would like to get it working on my Surface laptop as well as all my programming is normally done on that machine (XGecu T48).Here are some screen shot

The L6206Q datasheet Figure 14 "Typical Application" does not show the use of any additional SENSE_A or SENSE_B resistors connected to pins 45/46 & 15/16 respectively.  Section 4.3 talks about "the external current sense resistor normally used [being] eliminated."   AN1762 in section 3.5, discusses the selection of sense resistors and suggests that they might be part of the over-current setting process (which the datasheet suggests is handled entirely by the R_CL resistors).So which is correct? Datasheet or AN?  Are sense resistors required or not?  If they are required, how are they selected and how does that selection work with the selection of R_CL current limit resistors?

The Reference Manual (RM0454) of the STM32G0B0 points to an old 2020 revision while on the website it shows 2025.I believe this is a mistake since there should be a newer revision of this RM with the fixed Flash section (STM32G0B0CE) unless ST only fixed the RM of the STM32G0B1.

Hey there community,As you can see I am trying to move the free Rtos and x-cube-st67w611 middle ware from the application context to the FSBL context, I am using the stm32n6 mcu series and MX 6.16.0 version.I failed to see the full message suggested by the MX tool, as to why this is, I also noticed that in the example projects the context is fixed to FSBL, hence doable. my intention is to develop in the FSBL content and latter migrate to the application content.Does any one have a idea of what I can do to?

Inside Cube config, i do not get the other internal connected pins on pin 14, only PA8... in older versions it was available. The chip is STM32U031F8... What do i do wrong.. i need to use the uart_tx function on pin 14... Thank you  Old version from Cubeide... New version from Inet : 6.16.1 

Hello I am looking at the ST87M01 Startup sequence in ST87MXX Startup Application Note. For configuring the ST87M01 (Band locks, eDRX, PSM ...), I understand that I need to "Stop the NBIOT Stack", enter my configuration with AT Commands, store this configuration in flash and restart the module. is this correct ? How do I "stop the NBIOT Stack" ? Is it possible to bypass this automatic startup, i.e. send a first "AT command" at startup, execute a specific set of configuration commands, trigger the network attachment ... without rebooting ? Many thanks, Thierry

Here comes another query about the status of a HUB device for the USB Host library. I have been working with the driver from herehttps://github.com/moribr/STM32F4HUB/blob/master/Project/Middlewares/ST/STM32_USB_Host_Library/Class/HUB/usbh_hub.cand have the HUB functional but cannot seem to get the MSC initialized and working. Why does STM not support a hub in their HOST Library? There certainly have been enough inquiries.
