I would like to clear up some confusion regarding the DSI VIO, the stm32mp157a datasheet mentions "1.2 V I/O for DSI interface" but in the EV1 kit the LCD used (the RK055AHD042-CT, for which it's impossible to find a datasheet for, could that be shared too?) uses the RM68200 driver which seems to require 1.8V for IO.The LCD I would like to use also requires 1.8V so I'm wondering if I need a high-speed voltage translator or will the STM32MP1 support my LCD?

Referring to "mapping_sbsfu.h" file of the example "2_Images_OSC" of STM32f769I-Discovery, seems the DTCM and SRAM2 are not used in the project.So does it have a reason?

Hi allI have recently changed my computer, and reinstall STVD for the development of STM8 applicaiton.using cosmic compiler. In my old computer, I used to set up breakpoint by just double clicking the very left column (where line number appears) at the statement of the source code viewer, and a red dot appears making the breakpoint set. with my new computer, that does not work, clicking the mouse at the left column does not have any effect to set breakpoint. The alternative way is the right click popup and select insert/remove breakpoint.Is there any one out there having the same problem, and any way in settings to enable this feature?RgdsCalvin

Hi Team​I want to know the difference between X-CUBE-AI and NanoEdge AI Studio for ML and AI development environment.​Can I do the same thing with either dev environment?Are there any restrictions on the devices used?

There used to be a flowchart showing all the ways of programming the STM32H7 series through various ports including SPI, UART, etc, showing the order they are checked. But I can't seem to find it anymore. Can anybody point me at it please ?

Hello guys.Im a little confused about dma functionality.My question is that if dma controller can start a peripheral or it just can move data from the peripheral to memory.For example when using adc with dma:Is it dma that start the conversion and moving data from adc to memory or when we start the conversion by software (or timer trigger for examole) its the EOC flag that start the dma transfer procedure?In case of spi and dma if we dont want any cpu usage how would it work? In adc there is a connection between timer trigger out and adc that starts the adc by hardware but in spi i didnt see any. Am i able to use a dma stream that is connected to timer update channel request to transfer data without cpu starting spi transmit?

Anyone know  STM32H7 (STM32H743) support usb gadget ethernet?I read somewhere STM32F7 does, but not sure about STM32H7Many thanks.

We need STM32 MCU types for use in medical instruments. Does ST have Medical grade STM32 MCU's? It must be recommended for new design with long life time.

The ProblemA TextArea with one wildcard is used to display a floating point number centered in its field. When a larger number is overwritten with a smaller number, the new number is centered in the TextArea, but a “residue�? of the previous, larger number, remains visible on both sides.The issue is seen in the GUI of a client project for an industrial meter and process monitor, and is reproduced here in it's own TouchGFX Designer project which runs in the Simulator.Simple ScreenThe project includes a single screen with a white background, and three additional objects:A blue Flex Button (setBtn), labeled “Set 1.0�?A single-wildcard TextArea (numberText( with initial setting “345.67�?A red Box background (numberBgd) to the TextArea.Screen AppearanceTextAreaThe TextArea (numberText) is of fixed width, non-autosize, includes a buffer with a 16 character size. and has an initial setting og 345.67: Text ResourceThe text resource (numberDisp) specifies the default font, centered display

Hello, I am inquiring about USART communication using DMA. I am following github.com/MaJerle/stm32-usart-uart-dma-rx-tx tutorial using the low level drivers for a STM32L432. I have reception working with no troubles and I believe my interrupts are being hit okay. However, I am having trouble with transmission, simplifying the code from the tutorial I can't seem to get the USART to actually start transmitting the data. When I check the size of the DMA buffer it says it is full of 32 bytes, then when I start channel it never empties. Apologies if this is simple, but I've tried numerous combinations with no success. Thank you.

Hello, I many years use STM32, but first time when I ran into a problem.I can not compile the code STM32CubeIDE (same and TrueStudio). I pushed the button and nothing happen, I don't have any error, so I can not understand why I have a problem.Initially, the project was created in CubeMX6.6.1 for STM32CubeIDE (same and TrueStudio).In the image, you can see, I added a variable and pushed the build, and nothing - Nothing to build for project

At ST25RU3993-HPEV firmware how to control an antenna distance? For eg. I want an antenna to read tags in 3ft only.

Hi all,I purchased the nucleo-stm32g474 board and the z-nucleo-USBPDM1. I would like to use the USB port to communicate with the computer at speed (HIGH SPEED). I am unable to find an example of how to do this and how to communicate with the microcontroller.I will only add that I have run an example that works: github x-cube-tcpp/I would be very grateful for your help.Regards

Hi all !I want to enter the bootloader in system memory using the Nucleo-F429ZI but without success until now.As I understood, the only thing to do to enter bootloader at reset is driving pin BOOT0 High and BOOT1 Low.What I have tried is :solder the SB152 in order to have BOOT1 pin pulled downpower the board, user leds start blinking (standard FW)connect +3V3 and BOOT0 pin : the user leds stop blinking (I don't get why...)reset the board, the user leds don't blink (but I'm not sure I'm in the bootloader though)disconnect +3V3 and BOOT0 pinuse STM32CubeProgrammer to open an UART connection on the ST Link COM Port (115200 br with even parity) : failure to open connection - time out !Is there something I'm missing ?Any help much appreciated !

I have successfully connected USBCDC to stdout by redefining __io_putchar and can use printf to talk to a PC thru its virtual serial port but am not having any success with stdin (modifying __io_getchar). Anyone done this and can advise?

I have tried multiple different configurations, software trigger, hardware trigger, the only way to read ADC channels in sequence is to use DISCONT=1 and trigger each reading individually. I have minimized my project to a testcase where a software trigger should initiate a sequence reading channel 0 through 2 and the EOC and EOS events are counted in the ISR then printed over usart. Am I missing something? Both EOS and EOC increment by 1 after each ADSTART...// Main loop: DelayCycles(1000000); ADC1->CR |= ADC_CR_ADSTART; DelayCycles(1000000);   if(EOS_COUNT != old_EOS_COUNT){ old_EOS_COUNT = EOS_COUNT; etl::string<32> text; etl::string_stream stream(text); stream << "EOS_COUNT:" << EOS_COUNT << "\tISR:\t" << etl::bin << ADC1->ISR << "\n"; dbg << stream.str(); } if(EOC_COUNT != old_EOC_COUNT){ old_EOC_COUNT = EOC_COUNT; etl::string<32> text; etl::string_stream stream(text); stream << "EOC_COUNT:" << EO

Hello-We are working with two different boards for the STM32L062, schematics of which I have attached. The first is a bare-bones development board for general testing and the second is our product. I have a Cube32MX project that enables the features we need the product to use and toggles a GPIO pin every 2 seconds so there is something to measure indicating the code is running. The issue we're having is that the code runs correctly on the development board, but on our product the code not only doesn't run but most or all of the GPIO pins appear to output logic HIGH. I've tried commenting out the peripheral init() functions from the Cube project so that only the GPIO code should be running, but to no effect. I can't see any non-standard wiring on our product's schematic that would raise any kind of issues. Note that although our schematic shows an oscillator Y1 attached to the chip, this and the two capacitors have been removed. Clearly something on our product design is causing this is

I have created a project from one of the Example Applications in STM32 WB CUBE.I exported the whole of the code and renamed the project with the intention that it be independent of the original example. My development environment is STMCubeIDE.I made a few changes of variable names in main.cWhen I edit the project .ioc file from inside the IDE using MXCube, the variables I'd changed in main revert to their names in the original example.How is this happening? Is it possible to stop it happening?
