Solved

Dear STM32 team,I want to thank you, honestly, for a really great MCU chip. Well done.(just as my friendly feedback to you and company)When I say, the STM32U5xx is a really "cool" MCU - I mean two things:It is really cool, in terms of temperature:I am impressed: my board (with few external components, like LDOs, LED, OSC) draws just 20mA (in full-speed mode) - very impressive.And the die temperature remains almost with ambient temperature, 29C (in a 20C room) - very impressive.But "cool" means also to me having some nice features:I like the OCTALSPI: very nice to have now a free user QuadSPI interface:just: it would be nice to use OCTALSPI also as a regular "full-duplex" SPI interface, like any other SPI,in single-SPI mode (it is still a half-duplex SPI interface, instead, not a full-duplex as any other "regular" SPI)I like the memory size, esp. in a STM32U5A5 chip (huge flash memory, huge SRAM, even better as a STM32H7xx MCU, "cool")I like the new and additional features like CORDIC a

 Does anyone know the exact pin-out of these five pins? I cant find anything in the documentation. Hoping it will allow me to use an external programmer.

Today, I tried installing CubeIDE so I could get a sample project up and running to evaluate against a Nucleo 144 board.  This is my second attempt, and both times I get this error.  Nothing in the manual, cannot find nothing on Google either.  The IDE is *so* heavy, my mac struggles like notihng I have seen before, closing a window (like the product selector) takes more than 10 seconds where you are locked waiting for it.  Not to be deterred I am hoping the experience gets better... although based on past work I will probably end up trying Platform.io which seems far better than the Eclipse based IDEs'Anyway, frustrations aside, any idea what this error means and how I get past it?Thanks in advance..Gerry  

Recently working with spi communication in stm32g070rb using stm32CubeIDE (HAL library).SPI master receive interrupt triggered continuosly when there is no interrupt.But same code wrote in SPI slave its works perfectly.I also put Pull down resistorso My main problem is if i configure SPI master Spi rx callback automatically triggered again and again. Slave devices that rx callback function works perfectly. I think if any master mode fault what reason master spi interrupt triggered unwantedlyi have also one doubt if any did not connect miso,mosi,sclk pins to slave devices. i just load the code to master device then i see interrupt rx callback or error occurs. pls provide solution This code works properly in full duplex slave if i set full duplex master or half duplex master does not worksmy clock configuration is set(hopefully correct) i do not use slave select pin for i set this software(one master and one slave) and also give interrupt priority why this only woks slave not master

According to AN4879, PA9 must be used as VBUS Sensing and must not be re-used for other purposes. However, according to CubeMX, PA9 refer to USART1_TX and USART1 is the only port that supports memory reprogramming (STM32F103VET6 Datasheet Section, 2.3.10, "Boot modes") Does it mean that in self-powered devices, USART1 and USB must not be used simultaneously?  

Hi guys, this is my first post here on the forum. I'm starting my learning in STM and I created a custom board with a STM32F405RGT6, I followed a basic MCU operation schematic that I found in a video on Youtube, but the MCU is not starting. I did several tests to check if the USB connection was correct, if the voltages also worked well and everything is ok. However, I saw that I really don't get a clock from the crystal, the crystal I'm using is already known to me from other projects. So I'm leaving here a print of the connection schematic and if anyone can give me some light on where to look for the problem that causes the MCU to not start, I would be very grateful.:grinning_face: 

In the ADC scan mode in STM32 microcontrollers, the digitized value of all input channels is dumped into ADCx->DR. Is there a register or flags to find out which ADC channel the data currently in the ADCx->DR register```void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) { if(hadc->Instance == ADC1) { uint16_t adc_data; // Read the converted data from the ADC data register adc_data = ADC1->DR; //I don't know which ADC channel this data is related to // Process the ADC data as needed // ... } } void ADC_Init() { ADC_ChannelConfTypeDef sConfig; hadc.Instance = ADC1; hadc.Init.ScanConvMode = ENABLE; hadc.Init.ContinuousConvMode = ENABLE; hadc.Init.NbrOfConversion = 2; // Number of channels to convert hadc.Init.DiscontinuousConvMode = DISABLE; hadc.Init.ExternalTrigConv = ADC_SOFTWARE_START; hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc.Init.NbrOfDiscConversion = 1; if (HAL_ADC_Init(&hadc) != HAL_OK) { Error_Handler(); } // Configure the AD

Hello everyone, I hope you're having a great day. I was planning on buying this STM32 NUCLEO-U5A5ZJ-Q Board but as I was reading the user manual for the board, I realized there were no GPIO connectors for the board but rather there were these "ST Morpho pin headers",I was wondering where the GPIOs were but as I did some experimenting with STM32CubeMX I discovered that I can set the pins in the ST Morpho Pin Headers to GPIO input or Output. Does this mean I can use these headers as the GPIOs of the Nucleo board or are these meant for something else entirely? I'm sorry if this is a silly question but if anyone can help me clear this up I would be very grateful.

Hello STM32 Community,I hope this message finds you well. I am currently working on a project that involves integrating Bluetooth Low Energy (BLE) communication into an STM32CubeIDE project. Specifically, I am facing a challenge in reading the updated values of BLE Write Characteristics from a mobile client.Here's a brief overview of my setup:Microcontroller: STM32wb seriesIDE: STM32CubeIDECommunication: Bluetooth Low Energy (BLE)I have successfully implemented the BLE communication, and I can write data from the mobile client to the STM32 device. However, I am struggling to read the updated values of the Write Characteristics on the STM32 side.If any of you have experience or expertise in this area, I would greatly appreciate your guidance on the following:How can I set up my STM32CubeIDE project to efficiently handle updates to BLE Write Characteristics?What functions or callbacks should I use to capture and process the updated values from the mobile client?I have thoroughly reviewed

Hi,I have a Nucleo-U5A5ZJ-Q board which i replace the mcu with a STM32U5A9ZJT6.I'm trying to use LTDC to control a 800x480 LCD (WF50FTYAGDNN0#) via RGB888.Eventually running touchgfx, but I have fallen over at the first hurdle.I have read many tutorials and forum posts and no one seems to have the same issue as me. I started a blank project and followed thishttps://support.touchgfx.com/docs/development/board-bring-up/how-to/03-display-internalBut my display remains a black screen, I then probed PD3 (LTDC_CLK) where I expected the 25Mhz clock signal that was configured, but saw nothing. I also tried switching the pins "Max output speed" to Very High as I saw somewhere that this was required.I then switched PD3 to GPIO_Output and toggled it to make sure connections are correct. Is there something wrong with my clock setup? I tried a test of toggling a pin in the while loop with a 1ms delay and the scope says a full cycle took 4ms instead of the expected 2ms... but then I s

Hi,using the code below, the device will not run when set to 250 MHz (PLL1DIVR = 99).

Using the STM32U5xx MCU - I see that PA4 on STM32U5A5 can be OCTOSPI1_NSS signal as well as SPI1_NSS signal.Now, I want to use SPI1 in parallel with OCTOSPI1 (as QuadSPI). The SPI1 should be a SPI Slave Rx where OCTOSPI1 is my master QSPI Tx.I want to know this:If PA4 is configured, via ALT, as OCTOSPI1_NSS (output)can I configure SPI1 to use HW_NSS signal (also PA4), as an inputand the output signal on PA4 as OCTOSPI1_NSS is routed back as input to SPI1_NSS?What I understand:When I would configure PA4 as SPI1_NSS (via ALT) - it would become an input. OCTALSPI1_NSS would be disconnected as an output.But what if I leave it as a OCTALSPI1_NSS but I configure SPI1 to use HW_NSS signal (but without ALT again)?Would it be connected to the same PA4 signal, but internally, to read how OCTALSPI1_NSS is driven?I mean: can a signal, driven as an output, still be used as an INTERNAL input (for another device)?Actually, I guess the answer:How would SPI1 know which pin signal to use as HW NSS? It n

I have a problem with USB initialization on those specific MCUs. Initialization function generated automatically by CubeMX hangs on USB_CoreReset function. Specifically on USB_OTG_GRSTCTL_CSRST bit which doesn't want to set after the reset. The Cube examples (which are working) use USBPD library only which source is not given so I can't see how initialization is done there.With older USB32U5 where USB_FS phy is embedded everything works fine. Any ideas what should I change to make it working? My goal is to use it with tinyusb library since I don't want to use Azure RTOS or any RTOS in my project

I have a project with a STM32H747. I don't use the DSI functionality. I left DSI_CKP, DSI_D0P, DSI_D1N, DSI_D0N, DSI_CKN, and DSI_D1P unconnected. Can I also leave VDDDSI and VCAPDSI unconnected?

Trying to connect to a STM32H723ZGT6 for the first time. Does the ST/LINK-V/2 have to use the JTAG connection on this device as I feel it probably does? The 4 pin connection being for the STM8 only?

We are having 6 proto boards and out of 6 boards only 3 are working properly, I'll outline my observations: Similarities: All six boards can be programmed/erase the flash.Physically, the orientation of all components is the same for every board.Each board has a proper clock and reset.The BOOT0 pin is pull-downed on all boards.All boards show the same VCAP pin voltage (1.3V). Differences: In working three boards, the board is working as expected, but in the other three, it seems it is not running the program.The overall current consumption of the working board is about 20mA, while the non-working boards have an overall current consumption of about 9mA. Actions taken on the boards: Tested a LED blinking code with an external clock configuration and debugged it on both boards: Previously working board's LED is blinking as expected.Previously non-working board's LED is not blinking. Used the same code with an internal clock configuration and debugged

My STM32F303RE is running with an 8MHz crystal feeding into HSE:Using TIM4 I want to generate 700 interrupts per second, but I only get 318.As can be seen TIM4 runs at 64MHz and the following configuration should trigger about 318 interrupts:Using the following formula:(edit note - had a typo in the formula)interrupts_per_second := clock_frequency / (prescaler + 1) / (counter_period + 1)64 MHz / 3 / 30476 = 700The 318 interrupts are way off the expected 700 and I just can't figure why. Any ideas are highly appreciated.Thx in advance !Woyzeck 

Hi all,I'm investigating what I need to be able to update the firmware on my custom STM32 board (with either an STM32H7 or STM32F7 MCU) from a C#/C++ Microsoft Visual studio application via USB. This is for Windows 7/10/11.I found STSW-STM32080 but it says not recommended for new designs and that it was replaced by STM32CubeProgrammer (CLI specifically). I want my application to do the upgrading of the firmware without the customer having to install any additional software (like STM32CubeProgrammer).Does STM32CubeProgrammer have any redistributable libraries to do this? Is there a better way to do this?Thanks
