Solved

Hi everyone!I'm using a NucleoWB55 and the LPUART protocole to communicate with a SIMCOM module. I'm able to send via the LPUART the AT commands that I want and to receive it's answers. I'm now trying to print on my terminal the content of my web page. I connected a USB to TTL (CP2102 module) to observe the UART RX of the SIMCOM module. The module transmits the entire content of the web page but I can't get it on my STM32 via LPUART. To make it easy to understand here are some screenshots : Here is the terminal where I transmit via UART the received data:Here is the terminal where the transmit data of the SIMCOM module is connected: We can see the entire content of the web page.Finally the interesting parts of my code : Commands and reception buffers:                     I presume there's a problem in receiving and displaying the data received. I know my "received" buffer

I've been asked to write some firmware for a legacy board that has an STM32F102CBT6 mcu on it.I have been involved in other computer and mcu projects over the years, but not with an STM32F. I'd like to get up to speed by starting on some basic programs on a simple (but somewhat similar) development board. I'll be writing my programs on a Windows laptop.I see development boards like the NucleoF103RB pretty cheap. But I don't see a Nucleo102F.Since the board I'll be coding for was built in 2011, I can see how maybe mcu's available at that time are not so well supported with development boards nowadays. That's fine if what I learn by practicing with whatever development board I get will help me transfer what I've learned to my target board.Do you have any suggestions for a development board? Or maybe it doesn't matter, as any of them will do?Thanks for your help and suggestions!

We need the schematics to eb checked for 10W power output

I have a STM32G0B1VET on a test board and tried to use its USB host function to connect a flash drive. It just stuck at the function of "USBH_MSC_SCSI_Inquiry" in file "usbh_msc_scsi.c". It can't pass  the state of below:case BOT_CMD_WAIT:   error = USBH_MSC_BOT_Process(phost, lun);where the error returns "USBH_BUSY".I have tried to increase the stack and heap to 0x2000. And I tried several different flash drives (500MB to 16GB). The same thing happened. I have measured the 48Mhz signal which is good.I have tried putting 30 Ohm resistors on the DP and DM line.I have tried using GPIO pin to control the 5V line for flash drive.I have tried using 3.3V for flash drive.Does anybody have an idea what's wrong? Any successful case? Thanks.

Hello,I checked out the documentation about TouchGFX (Link) and additionally installed TouchGFX as standalone software (without CubeMX).I would like to know, whether this framework can be used for other (non-STMicroelectronics) ARM Cortex MCUs. I found this page in the documentation which describes how to use TouchGFX with or without RTOS but the whole documentation seems like based on using CubeMX. I cannot find any "straight forward" initialisation routine for TouchGFX to use for other MCUs. Is it possible to use TouchGFX with any other ARM Cortext MCUs and if yes, is there any documentation for setting up the project and initialisation of software? Thanks,Best regards!

Hello, I have made a simple application with STM32G071RB_NUCLEO and an X-NUCLEO-GFX01M2 I TouchGFX. The problem is that the needle in the Gauge or the hands in the analogue clock are not displayed. When I look at Memory Details in STM32CubeIDE I can see the files. Does anyone know how to fix it? Br. Stig Hansen

hello sir       I am using the fast transmission mode of the nfc chip ST25DV04KC to transmit picture data. The NFC chip is used with the MCU of  STM32G071G8U6. When I write the 25KB picture data through the mobile APP into the NFC cache, I find that the entire writing time takes about 11 seconds. Please tell me know, Is the transmission and writing time normal? If not, what is the error? If normal, is there any other chip or solution that can replace it? I need to control the entire time within 4 secondsThank you.

Hello everyones, what are the red marked devices in smd format, diodes maybe? They are grey and yellow. There are no label on them.

Hello all,I have a question about additional MPU protection provided by enabling SFU_MPU_PROTECT_ENABLE.What are the main benefits of that?How much "protection value" do we miss if it's disabled? 

Hello all,I got a stm32f401vgt6 demo board from aliexpress and I created a project on stm32cubeide.  I wrote a simple problem " A = A +1" and downloaded via SWD communication.  All went well with download verified successfully message shown. The program halted just right after the download. In debugging, I got a message saying "Break at address "0x0" with no debug information available, or outside of program code."  I did the same thing on other boards such as F401x, F411x, F103x..etc., none of them has this issue.  This is the only stm32407vgt6 board did that.  Can someone point out what I needed to get this resolve.  I am very appreciated.  

Hi, could someone explain me what is the difference between wake up and alert in RTC?For example the UM1749 provides information about RTC Alarm functions (section 39.2.8) and wake-up functions (section 40.2.2)When should I use the wake-up and when the alert?

I am currently developing with the STM32G474 series, and there is a bug in the TIMER A setting of HRTIM.To make OUTPUT1 and 2 differential outputs with dead time, enable SWAP OUTPUT.If you set OUTPUT1's Source , Reset Source setting, cannot set the source and reset source of OUTPUT2.However, Timer A cannot set the Set Source and Reset Source of OUTPUT2,and the other Timer B, C, D, E, and F can set the Reset Source. In fact, the reset source for OUTPUT2 must be set for the outputs to function properly.Please fix so that the reset source of OUTPUT2 of Timer A can be set. 

hello，I want to download software from ST Website ,but there is not button to supply. when i didn't log in, there was a "get software",but after i logged in, it disappeared.thank you.

Where can I find the SVD file for the stm32wba52? Sincerely,Dana

I've been using LVGL for a while and I must say, their implementation (much based on CSS styles) is good to make responsive designs that scale based on screen size. Their concept is very simple, every object have a flex property that can be enabled. Objects put inside flex containers, for example, are automatically arranged inside the container in rows or columns. If the container size change, the objects are rearranged. There is also the grid option. This make possible the implementation of responsive designs very easily. So far, so good. But there is a problem: LVGL dropped their support for DMA2D acceleration on their latest major version. They expect to have some kind of official partnership with ST for bringing this feature back. I'm totally against this kind of behavior on a project that take benefit from community sent code. It's a total bummer!It's been a while since I have used TouchGFX for the last time. Some of my projects makes use of displays of different resolutions. Is t

Hi I'm new in working with CAN-bus. My project involves two stm32 boards (both are nucleo-l433rc-p) and I want to get CAN-bus communication between them. The code is supposed to make a build in LED blink each time the blue button on the main nucleo board is pressed (although I would be happy to get any CAN communication at all). Relevant code: Main: Relevant code secondary: Hardware:      

Hi all, I was wondering is there was a function pack or GitHub repo anyone has found which indicates how to implement CDC USB communication from the SensorTile.box PRO to a PC in STM32CubeIDE? Thank you in advance. 

Dear all,I'm attempting to use fast transfer mode with a ST25RDV04K type 5 tag and the STEVAL board for 3916B. I know this theoretically works because I have some Java code that is able to do it successfully, but I'm porting the code and I keep running into this issue and I can't see wht.I've enabled mailbox mode;I've send the mailbox message;I'm trying to check the mailbox control register to see if the remote device has posted a response. I'm using the iso15693TxRxNBytes() call with the Fast Read Dynamic Configuration command, register 0D (Mailbox Control Dynamic). This operation appears to not receive any data and results in the FramingError error code.I would appreciate any suggestions. Here's my diagnostic log:NFC|INFO | | Waiting for beacon...

I'm new to ST25R2916B programming and the RFAL NFC library. I'm currently writing board bring-up firmware and would like to know the correct way of updating the AAT A/B values in both the CHIP_INIT and POLL_COMMON modes of the Analog Config table while keeping all the other parameters in their default values. I currently read the AAT A/B values from Flash and would like to load it in the Analog config table on start-up.Questions:I don't quite understand how to use the rfalAnalogConfigListWrite() API - is this the right API to use? For example, if I want to update the AAT A/B values in CHIP_INIT, can I pass just the new AAT A/B reg-mask-value or pass the entire list of 20 reg-mask-values found in CHIP_INIT? How do I set the Config ID for CHIP_INIT and POLL_COMMON? I looked in the config ID defines in rfal_analogConfigTbl.h and didn't find anything for these two modes.Do I need to call the rfalSetAnalogConfig() function after I change the AAT A/B values?Since I'm just doing boa

Hello, I am confused in selecting the development board for the microcontroller STM32U585OIY because there are multiple series of it. I am working on a project which uses this name in their schematic STM32U585OIY and I wanted to buy a development board for the same.Can you please advise me which on I need to buy? 

Hello!I am using STM32 Cube Programmer API to flash a device with ST-LINK. I am using ST-LINK example 1. When I use connectStLink(debugParameters) it returns the value '-545'. Doxygen comments say that if it returns 0 the connection was successful, otherwise an error occurred. I can't find any more documentation about it. Surely the value '-545' indicates to some specific error. After using the getStLinkList() function, the debugConnectParameters look okay, so it means it gets a connection with the device.I can flash (debug) the device through VS Code (using the official STM32 VS Code Extension) and through the STM32CubeProgrammer app with no problems. During one runtime, after a couple of unsuccessful tries it actually flashed the device for a few times and then stopped working again (returnind -545). I haven't made any changes to the code or the connections.I am using mikroProg for STM32 with the ST-LINK V2 adapter. I tried different USB ports with no luck.There isn't much informatio

What exactly is meant by "If Boot from FLASH"?

Hi Community,I have a bitfield arrangement for one of the driver files which is a 32-bit value. While debugging I was not able to figure out how it is being stored in the register. The bit order and endianness are not always guaranteed in structs and bit fields but I want to have a fair knowledge on how it is being stored.Bit field arrangement typedef union { uint32_t value; struct { uint8_t data_1 : 4; uint8_t data_2 : 3; uint8_t data_3 : 4; uint8_t data_4 : 2; uint8_t data_5 : 1; uint8_t data_6 : 1; uint8_t data_7 : 2; const uint8_t data_8 : 3; } field; } reg_t; If I assign a value to fields of data like below the expected 32-bit value data.field.value is 0x88372. reg_t data = {.field.data_8 = 4}; data.field.data_1 = 2; data.field.data_2 = 7; data.field.data_3 = 6; data.field.data_7 = 1; But I am getting 0x110672 why?
