We are doing a custom board bring-up and currently trying to display video on our display device. We use CubeMx to generate the device trees for our project, we have configured the DSI PLL dividers to match our display device requirement. Snapshot of the configuration is shown below.In the device tree's rcc node, we do see the CLK_DSI_DSIPLL, however we are not seeing these divider information.The clock configurations for rest of the peripherals are reflected in the device tree, also the clock dividers to generate DSI pixel clock are present in the rcc node and in the target's clock summary dsi_px clock shows the configured clock frequency. The clock configurations for DSI lane clock is not seen in the device tree and also in the target it shows 200MHz instead of a 174MHz when measured. Are we missing anything here? Where is the DSI PHY configurations in the device tree?

Brief: I am using cubemx to configure and generate code.MCU: stm32wb55rgvxfirmware package name and version: FW_WB V1.13.3Details:I am working on a project where the stm must act as a bridge between the PC and the device under test (DUT). We use the newtmgr tool on the PC to transfer/upload the firmware on the DUT via the stm at baudrate of 1MHz. For this, we are using two uarts on the stm i.e. USART1 connected to the PC and LPUART1 connected to the DUT. All packets received from the PC must be relayed to the DUT and all packets/responses received from the DUT must be forwarded to the PC.I have attached the .ioc file that shows how I have configured the two uarts to be used with DMA's. I'd like the DMA's to work in the following cyclic order since it's a request-response mechanism.Receive packet from the PC over USART1-RXRelay this packet to the DUT over LPUART1-TXReceive a response from the DUT on LPUART-RXRelay this packet to the PC over USART1-TXWith the above configuration, the tra

I'm looking to connect a Waveshare e-Paper display to my STM32U5 discovery kit (B-U585I-IOT02A).On the Waveshare website (https://www.waveshare.com/wiki/7.8inch_e-Paper_HAT), they have a pinout for the SPI bus on a STM32F4 chip as follows:Connect to STM32F429IGT6 (SPI)IT8951 STM32 Description5V 5V 5V Power inputGND GND GroundMISO PE13 Data outputMOSI PE14 Data inputSCK PE12 Clock inputCS PE11 Chip select (Low active)RST PC5 Reset (Low for reset)HRDY PA7 BUSY state output (Low for busy)What are the equivalent pinouts for the STM32U585? 5V/Gnd are obvious. I think MISO/MOSI/SCK/CS go to PE12/PE13/PE14/PE15. Perhaps HRDY goes to PA8, but I'm not fully sure. I don't know where RST(PC5) maps to on the STM32U585. Can you please help me?Also, if I wanted to bypass this RPi HAT, what would you recommend?Thanks,Vince

I'm trying to use the STM32WB firmware event callbacks defined in ble_events.h and ble_events.c but they don't appear to be working.According to the documentation in PM0271 revision 2 section 4.4 I should be able to use the event callbacks framework as an alternative to the switch/case event handlers.However when I implement the event, it never gets hit (tried both with and without the __WEAK attribute):__WEAK void hci_le_connection_complete_event( uint8_t Status, uint16_t Connection_Handle, uint8_t Role, uint8_t Peer_Address_Type, const uint8_t* Peer_Address, uint16_t Conn_Interval, uint16_t Conn_Latency, uint16_t Supervision_Timeout, uint8_t Master_Clock_Accuracy ) { Debug_print("hci_le_connection_complete_event called!"); }But in my switch/case events I do get the EVT_LE_CONN_COMPLETE event triggering.The version of the STM32WB firmware I'm using is 1.10.0and the firmware loaded onto my P-NUCLEO-WB55 development board is V2J37M26loaded with STM32CubeProgrammer v2.5.0.I did

Hello I installed spc5studio that downloaded from ST website and it works correctly. But in software, I can't debug MCU with spc5studio. I checked windows/preferences/Spc5studio ​ but there is not "Debug Options". How should I debug with spc5studio?

STM32CubeIDE Version: 1.9.0Hal MCU : v1.5.1Chip: STM32G061C8U6 If you enable USART1 in asynchronous mode for pins PA9 and PA10 the auto generated code incorrectly sets the port to AF0 when it should be AF1 see datasheet table 13 or port.png.When set to the correct port it transmits but at very low amplitude of a few mv. See scpoe.pngSetting the pins to PB7 and PB8 UART works fine.How to get it working for pins PA9 and PA10?

Hi all,I am using STM32F303CB microcontroller, connected with a I2C slave which has no CLK stretching support. The I2C bus lines are pulled high with 4k75 ohms resistors and the lines have a serial resistor of 50 ohms (approx.). The schematic looks like the one in the image below. The routine I have in configuring the slave and running it in normal mode, is the following.Reset the slave using HAL_I2C_Master_Transmit().A delay of 100 ms.Config the slave using HAL_I2C_Master_Transmit().A delay of 1.5 ms.Run the slave (from config mode to normal mode) using HAL_I2C_Master_Transmit_IT().The circuit was implemented on certain number of PCBs and the routine works fine on most of them. However, on certain PCBs, the slave does not start properly and the issue was found to be with the step 5 of the routine I mentioned above. Normally, the transmitted data should look like the image below (0x2A -> slave address, 0x0A -> memory location inside slave, 0x00 -> data to be written insid

We are trying to sample a 50Hz to 200Hz signal at 50Khz rate, using stm32H7 micro controller, ADC-DMA mode is used. Tried to plot the wave in cube monitor by accessing the corresponding variable. the issue is 50Hz waveform is not reproduced properly, while if the signal frequency is reduced to 1Hz, the waveform is plotted and reproduced perfectly. Till 5Hz the waveform looks fine. Beyond that the waveform is not proper. Tried changing the sampling custom sampling frequency in Cube Monitor beyond 50kHz. But looks like no change. If we need plot signals till 200Hz, how this can be done. We need to sense and plot around 12 ADC channels. Need suggestions, if any settings to be changed in cube monitor or IDE. Tq

When I do a build in STM32CubeIDE 1.9.0 the console window looks like this: But if you scroll up a bit...You can see that the build actually failed. Those errors are real.I could make the window a bit taller I suppose, but shouldn't it stop building when there is an error, and at least show the error and warning count on the very last line?STM32CubeIDEVersion: 1.9.0Build: 12015_20220302_0855 (UTC)OS: Windows 8.1, v.6.3, x86_64 / win32Java vendor: AdoptOpenJDKJava runtime version: 11.0.11+9Java version: 11.0.11

Hi,I am using a microcontroller STM32L4R9AII6 on a STM32L4R9I-EVAL board, with IDE STM32CubeIDE (version 1.9.0)I am trying to run a fairly simple code in Debug Mode, that just toggles a LED using some software overlay we developped.It seems that after a determined number of instructions executed, the program get stuck in "Running : User Request" mode. (See picture error1)I've noticed that my main while loop get executed everytime 18 times, and then the program get stuck.I've tried adding somme dummy instructions inside the main while(1) loop, and the program then get stuck before (11 loop executions), as if a pre-determined maximum number of instructions could be ran.The code that is being executed does not seem faulty at all, and have been running pretty well before.When pressing "Suspend" once stuck in the "Running : Use Request", I get the error shown on picture "error2".At this point I don't really know where to look and can't really explain anything of what is happening.

Hello, ST expert​In our custom MCU board design, some GPIO pins can be drived HIGH before MCU is power on. I found that sometimes (low possibility)these GPIO pins damaged, that means these pins can not be drived high again. I am not certain it is caused by the power sequence. Is there any suggestion about this?And by the way if VBAT pin is present and VDD is not, does GPIO part in MCU workes as VDD is present?

Hi,I'm looking at how compiling TouchGFX applications work, and it appears that you have to compile the TouchGFX project and then flash the board with the application.https://support.touchgfx.com/4.19/docs/development/ui-development/working-with-touchgfx/compiling-and-flashingI'm trying to figure out if its possible to hot-load applications onto a device like an app store, and install new widgets without having to re-flash the entire image.Thanks!

My code is larger than expected and I am close to the 32K program boundary of my device. When I optimize for debugging or have no optimize I cannot test new code. When I optimize for size I have plenty of room for the new code, but single stepping through the code to find a bug is a problem because the optimization jumps all over the place. So can I optimize for size the files that I know are good, and optimize for debugging or no optimize the files I am working on? It appears it is optimize by the whole project. If I change the optimization, it recompiles the whole project to that optimization. The new rev of the board increases the memory from 32K to 64K but that is not going to happen for a couple of months, and I need this version working before they will release the new board.

Hello,I am trying to connect to my STM32F429I-DISC1 (E01 revision) board's USART1 on pins PA9 and PA10 using an FT2232HL as USART to USB interface. I've seen in the user manual of the STM32F429I-DISC1 that the solder bridges SB11 and SB15 connecting ST-LINK to USART1 and enabling VCP where on by default. I am wondering if this might prevent me from accessing USART1 via pins PA9 and PA10 and if I have to disable this solder bridges or if it has no incidence over it ?​Thank you.

Hello,I want to update the MCU firmware using NFC.I have a iphone and will create an app or use existing one, and st25dv dynamic tag which uses I2c to connect with stm32f411re.And want to create a custom bootloader in flash similar to BL provided by stm32 which is in system memory. The following steps are the one which I perform.I open the app and then select firmware upgrade.Selecting the file to flash. Click Start transfer and enter password.press start transfer to start transmitting binary image.Implementing logic in code:Application is already running and I do the above steps, then the mcu will detect the nfc message and then will do soft reset (system reset), then bootloader starts running.What should i do now to get the new firmware.?I mean my question is, how can the MCU say, hey iPhone, im in bootloader please start sending the firmware now. (I got this question because, i already pressed start transfer button in the iphone which made to swtich to bootloader code after system r
