STM32 MCUs Products

Hello,Short: I'm developing a USB to I2S bridge, hopefully multi-channels in the end. I don't understand ST designers intention about flow for I2S DMA callbacks . How to do it correctly as expected by ST designers, based on CubeMX generated code? Longer: I want to rely as much as possible on CubeMX code generation and on ST USB UAC1 middleware for future portability reasons. I have a difficulty to understand how ST code intends to implement the mechanism to rearm the I2S DMA once the first transfer is complete between the usbd_audio_if.c and the driver BSP code, I looked at 3 ST examples:Audio_playback_and_record for STM32F4-DISCO (the board I have for development). DMA call back BSP_AUDIO_OUT_xxxxTransfer_CallBacks are coded inside waveplayer.c application code, not in the BSP drive code. Example is working,AUDIO_Standalone for STM324x9I-EVAL. BSP_AUDIO_OUT_xxxxTransfer_CallBacks are coded now inside usbd_audio_if.c

Hi, everyone I am Talha an Electronics student, I was recently working on making an oscilloscope using STM 32. I recently made a logic analyzer using stm 32 f103 RB. I now wanted to make a simple oscilloscope that simply displays the function generator's data. What I want is that I want to give an input signal using a simple function generator and display it on a serial analyzer. Now I don't get the problem as I tried to simply read the data and send it to USART and display it on the serial analyzer but unfortunately, there was a lot of noise, I don't get it what should I do, I have 2 STM 32 one with an ADC in it.It is a request to please help me If you can. I also need to integrate the output with a GUI I've designed using Flutter, but I would take care of it on my own.Help needed anyone with a similar experience please help.

Hi,Just yesterday on my H743VIT6 (rev. V ) on the running TFT : picture faded away...white screen.I just happened to look at the display , thinking ...ok, maybe one of the thin wires just broke now...TFT (small, 1,8" , ST7735 on 3,3V) connected /soldered about May 2022 , on SPI2 , at 48 Mbit . :)(Not touched/changed the wiring since then - so no static problem etc. possible.) Today i tried to fix the problem - but everything still connected !So took the scope to check the signals, beginning with reset ...all look ok, except SPI data !Here super slow rise time...ok, no useful signal for the TFT at 48Mb. (PC3_3 is sick ?)First check short to next pins - no, all free. Then impedance of pin unpowered : high, as cmos should be.Hmmm....try other pin: in Cube could choose PC1 as SPI2 data tx , so i changed to this and soldered the wire also here. (Soldering iron is antistatic.)Hey, TFT display ok, as be

Tried implementing ADC conversion on STM32H563ZI Nucleo board. But, getting only a constant value like 66,67,68,69 in serial monitor(Tera term) irrespective of the given input even the i/p is unplugged getting the same values. Need a help to fix this. Thanks in advance!

Hello Community,We are selecting a high stability 12.288MHz HSE to clock our RTC on STM32G0 series MCUs.Kindly suggest if the HSE/32 which is 384kHz would be able to operate the RTC? I did not find any mentions of the maximum clock frequency for the RTC on STM32 MCUs. I understand the RTC has a prescaler, kindly direct me to the correct configurations.Clock Tree configuration using HSE with 12.288Mhz as clock input for the RTC on STM32G0

I have been trying to get a TMC2209 and STM32F103 working over UART for a while now.I have followed 2 posts ( I am pretty sure correctly ) on this but I can't add them here as I am a new member, they are already on this community.I have found online that I need to bridge a connection at the back of the driver board I am using, I have done that.I have also found that for the start UART comms I need to set "GCONF.pdn_disable = 1"I think that is done correctly in the code below but feel free to correct me.I have connected a 1K resistor between the Tx and Rx lines as in the datasheet and in one of the posts above.My problems start with the UART connection I believe.I have included nothing else in this code so I can just look at getting this working.I get a 0x05 on Recv[0] each time I run the code but I do not get any other values, I expect to see 0xFF in Recv[1] but I get 0x00.

I am trying to figure out what UART mode do i set in CubeMX configuration for my STM32F407VE in order to connect stepper motor driver TMC2209? Should it be Half-Duplex?This question may fall on TMC2209 manufacturer. I searched the forums but I only see arduino based TMC libraries and know less about STM32 based libraries for TMC2209.page 15 - https://www.trinamic.com/fileadmin/assets/Products/ICs_Documents/TMC2209_Datasheet_V103.pdf

Hello, I would like to contact you because, following the code made on Keil uvision 5, I cannot get my interrupt to work.Objective of the code, turn on and off the LED (pb0) of the card with the button (pc13) on it itself.PCB Used : STM32F767ZI

Good day I am not sure what I am doing wrong as I was quite successful on other dev kits to import examples. I have downloaded en.stm32cubef2-v1-9-4 from the ST website and I am trying to import some of the examples from th eProjects->NUCLEO-F207ZG->Examples and Examples_LL and Examples_MIX. I am using STM32CubeIde V1.14.1 and none of the examples want to import. I am currently trying to get the Uarr to trigger the interrupt when a character is received. I can even measure the character I send using a scope, but the interrupt does not trigger. I can send a cahracter and that triggers the Interrupt   I hope someone can help.

Is there a newer version of this infographics:https://community.st.com/t5/image/serverpage/image-id/44904i6E7E4466B43E7167/image-size/large?v=v2&px=999?It was used in the "10 years of STM32" campaign.If there is no such, can please such infographics be produced? It could accompany a "17 years of STM32" campaign :)Thanks,JW

HiI use HID host as USB profile for getting barcode from scanner (ES4650 scanner).I use STM32F746.Most of the time I get the right barcode, but sometimes it misses a character .I tried giving its interrupt the top priority, but it didn't solve the problem.When trying the same scanner on a PC with a PC software, I always get the right barcode.What can be the problem ?ThanksOfer

Hello all,I have been trying to get I2C communication working on my NUCLEO-U5A5ZJ-Q board based on STM32U5A5ZJJT6U. First I have used STM32-CUBE-IDE and CUBE-MX to generate code but I was getting error when I try to transmit so I write a custom code which is also attached attached and after doing a bit of stepping through the code, it looks as though a HAL_TIMEOUT occurs when the I2C driver executes the I2C_WaitOnTXISFlagUntilTimeout() function and the exact error I am getting is as belowif ((__HAL_I2C_GET_FLAG(hi2c, I2C_FLAG_TXIS) == RESET)){hi2c->ErrorCode |= HAL_I2C_ERROR_TIMEOUT;hi2c->State = HAL_I2C_STATE_READY;hi2c->Mode = HAL_I2C_MODE_NONE;/* Process Unlocked */__HAL_UNLOCK(hi2c);return HAL_ERROR; /// HERE IT RETURNS ERROR IN MY CASE ///////}I have looked through the datasheet for this particular micro to figure out why this flag would not be set, but it is not immediately clear and it is con

I am sending a command to the STM32F405 through the UART (COM) port for receiving data from the STM32F405. Once the command send from PC it will continously send data from STM32F405. What if the PC drops the connection and goes to sleep. And my STM32F405 still performing to send data and how can I make the STM32F405 to stop automatically. I couldnt find much details on this. Any one could help on this matter. Thank you

Hi,     Configured PC4 and PC5 for transmitting and receiving over USART1.    Enabled the interrupt, DMA is disabled.     Tried with different baud rates, same results.     The data seen on serial console application cutecom does not match data I am setting in my transmit buffer.      Tried same test on USART2 using putty, it shows data matching TX buffer.     Any suggestions ? Thanks,   Mo

We are developing using the following development environment. Are there any libraries or SDKs that we can use?Also, Is HAL or LL a library? [IDE] STM32CubeIDE 1.14.0[MCU] STM32F412VGT6

The STM32H562RG USB interrupt does not work.Also, using the library on the Nucleo-H503RB results in a memory error. We verified the other chips work fine, but the H562RG has a problem with the USB interrupt not working.

Hello, I am making a development board where I want to use STM32 and USB C connector for power supply to the STM and also for UART communication with the PC. What are the best solutions for this? I looked into using FTDI chip but they are quite expensive. Also, not really sure how to connect the USB C connector for this to work. I am using STM32G0B0CE which has a USB NOE pin which im also not sure how it works or where to connect it.  Any help or referrals will be welcome  

Hello all, I am using the STM32U5A5QJ in a project and I had a question about some of the wake-up modes. I would like the microcontroller to be in stop mode 3 most of the time until it receives an interrupt from a sensor to return to normal mode. The data sheet seems to specify two ways of doing this and I’m wondering which is correct or if both can be used. In Table 9. STM32U5Axxx modes overview it says the wake-up source for stop mode 3 is one of the 24 WKUPx I/O’s.There is also a section under Extended interrupt/event controller (EXTI) where it says “The EXTI wake-up requests allow the system to be woken up from Stop modes.” They both seem to say that they can be used to wake-up from stop mode, is this correct or should one be used over the other? Thanks for your help,

Hi,We have a custom board based on STM32H755. We have two configuration of this SoC. In the normal operation we run a Bare-metal application on M7 and Zephyr OS application on M4 in a dual core mode. When requiring firmware update, we run a Zephyr application on M7 alone. 1) In the dual core mode, M4 Zephyr OS sees two flash partitionsimage2 - read only - 896KiBbootloader - read/write - 128KiB2) In the firmware update applicationM7 sees both banks and following partitionsBank 0image1 - read-write- 896KiBconfiguration read/write - 128KiBBank 1image 2 - read-write- 896KiBbootloader - read only - 128KiBI am able to update bootloader partition in 1) without IWDG1/WWDG1 enabled.

Hello everyone,I will put the device on standby as part of my project. I set the GPIO Pin as SysWakeup1 pin. Can I reconfigure the pin that I configured as SysWakeup1 in the main.c file as external interrupt or gpio input? We can dynamically set GPIO as output when it is input, but is this valid in SysWakeup?
