Hello,I use EP1 (IN/OUT) for bulk transfer(64 byte) and EP2 (IN) for interrupt transfer(64 byte).I need to use the Vendor-Specific Class for this configuration. Using STM32CubeIDE 1.18.0 to create a usb device, which class shall I use to create this  USB configuration. I tried using the Communication Device Class, because it includes EP1(IN/OUT) for bulk transfer andan interrupt transfer endpoint.(primarily for sending notifications back to host)Instead of using interrupt transfer endpoint for sending notifications,I tried modifying this endpoint to send data back to the host when it polls for it.However, the USB device does not seem to respond to the host polling.Is this the correct way to do it?I have also attached my source codethank you very much!!

Hi,I probably didn't search correctly in the documentation, but i didn't find a command to reboot the device using the USB Bootloader interface . I found a reset method but its with STLINK and its not what i'm using.Is there any method available ?thank you for all the help you can provide Sofiane

A similar problem to this post but not quite the same:I've got my own low-level LPUART transmission code, it works like this:1) Initialize LPUART in FIFO mode with thresholds at 1/2 full2) When a buffer needs to be sent, write bytes to TDR until all bytes sent or transmit FIFO is full3) If transmit FIFO is full, enable USART_CR3_TXFTIE and let the ISR handle the rest.4) When the ISR has written all the bytes to the FIFO, it disables USART_CR3_TXFTIEWhat I see is this:1) Send first packet.  It's 10 bytes long, the first byte gets moved immediately to the TX shift register and 8 bytes fill up the FIFO so there's 1 byte left.  The interrupt is enabled, the ISR fires, the last byte is written to the FIFO, the interrupt is disabled.2) Send second packet.  It's 7 bytes long so fits completely in the FIFO and the interrupt is left disabled3) Send third packet.  It's 71 bytes long, the first byte gets moved immediately to the TX shift register and 8 bytes fil

I want to use the ULPI interface & both the CAN interface for my project But I see  For USB:   Pin No: 194     pin name: PB5     Module function :  USB_OTG_HS_ULPI_D7,   ONLY ONE PIN no other pins are there   For CAN   Pin No: 194,195    pin name: PB5,PB6     Module function :  CAN2_RX,CAN2_TX     Pin No: 104,105    pin name: PB12,PB13     Module function :  CAN2_RX,CAN2_TX      How to proceed with it, since we have clash with Pin No 194?

Hello I am looking for STGIK50CH65T demo board named STEVAL-IPMHF50G.Can you tell me when will st official find this demo board information?STM32 MCSDK:6.3.2CubeIde :1.6.1 

In the App Note, AN5949 "SR5E1 line - 7 KW EV/HEV on-board-charger reference design", there's a mention of "A dedicated Lauterbach script (SR5E1_multicoreAMP.cmm file) has been released to debug in AsymmetricalMultiProcessing (AMP) mode the main cores of SR5E1: Core_1 and Core_2." Can you please provide a link / attachment for where I can obtain this file.I'm trying to run multicore simple applications via a cmm script, but I'm unable to obtain a stable connection over multiple resets.Regards,Steven Daglish

Hello ST community has any one an idea what this ST chip is as shown in the picture?I haven't found any datasheet of this device.

Hello, I am developing an application using STM32N657I have datasheet DS14791 Rev 4. There are pins for VDDIO2 to VDDIO5 and the datasheet implies that I can run the GPIO on an independent voltage supply. Chapter 5.3.17 even specifies low levels and high levels for 1.8V mode and 3.3V mode. I need SPI and UART at 3.3V level. I know that VDDCORE is 0.8 V, for this I will use the internal SMPS at 1.8VSome of the voltage signals have 1V8 in their name so obviously these run at 1.8V However I am not completely sure how I can/must supply the rest of the chip.Can i supply VDD and VDDIOx with 3.3V and have all the GPIO work at 3.3V? What else do I have to keep in mind when using 3.3V on this chip? ThanksLucas

Hi ST Experts, I am working with the P-NUCLEO-53L8A1 evaluation kit and have followed the user guide to install the necessary software packages and GUI. I was able to detect the STLINK COM port connected to the evaluation board. However, after refreshing the list and attempting to flash the firmware, I repeatedly receive an error message and am unable to connect to the sensor successfully, despite multiple attempts.   Could you please advise what might be causing this issue with my board? Thank you. 

I am unsure if I correctly understand the power consumption of the N6 Family. I want to supply the MCU with 1,8V and use the internal SMPS to supply Core with 0,81V.When it comes to designing the 1,8V voltage source, how much current do I have to expect? Datasheet chapter 5.3.6 details supply current characteristics- I see that I_DD is almost negligable in the grand scheme (less than 1 mA)- CORE supplied by SMPS is given as current I_DDA1V8, order of magnitude around 100mA typ- I_DDA1V8 in and of itself also quite small with around 5 mA- I_DDA1V8AON itself also around 5 mA- Table 39. shows current consumption of SMPS, the given current is also I_DDA1V8AON with values up to 100 mA typ. Since some currents are defined multiple times in different tables I am having trouble to understand which values to take for a maximum current calculation.Do I have to add all together?Also, CORE supply without SMPS through I_DDCORE needs less current than when supplied with SMPS through I

Hello everbodyI am struggling creating a project which uses the ART-Accelerator and compiles. There are always some errors. It feels like i searched every possible document from ST but i haven't found a basic get started guide or something like that which uses the Nucleo-N6. I also tried multiple combination of FSBL, Application (even though i am not sure when to use which but thats a other topic).The basic template which auto generates when making a new project ran. I wasted already so much time on this so any help is welcome.How i am creating a project in CubeIDE:- New project and choose Nucelo-N6 with FSBL only- Go to .ioc choose X-Cube-AI 10.0.0, tick core and choose application template- load model and run analyze, validate on desktop and take a look at the Graph: Graph looks weird with blocks not connected, if i choose MCU runtime Graph looks fine but i want to use NPU- Save and generate Code- Try to compile -> Errors../X-CUBE-AI/App/app_x-cube-ai.c:100:5: warning: implicit de

Hi There,I am developing an RF link application where I need to transmit 64 bytes of data at 20-50 Hz over a range of 5-10m with some obstacles in the way. For robustness, I was looking at sub GHz devices, such as the STM32WL55. I purchased some NUCLEO-WL55JC1 for testing, and have been testing the example applications provided in the STM32Cube_FW_WL_V1.3.1, such as STM32Cube_FW_WL_V1.3.1\Projects\NUCLEO-WL55JC\Applications\SubGHz_Phy\SubGHz_Phy_LrFhss. However, the radio sending is far too slow for my application. I removed the dependancy on the sequencer and call Radio.Send from my main loop (see below). It takes 1900ms for the TX to be done, see screenshot below.  My question is can this chip even send 64 bytes at 20 Hz? Am I just using the wrong example code, or is this chip just designed for a different application than mine (much longer range, lower datarate) and I am wasting my time here? Thanks for taking the time to read this and I hope to hear from you soo

Split from STM32CubeIDE and STM32CubeProgrammer produce different results when flashing .elf files.Hello everyone, and sorry to dig up this thread (as it's been left open).We're also experiencing this issue, and it's impacting the CRC calculation due to a few 0x00 bytes that, for some unknown reason, are 0xff in Flash (first image below), thus preventing an update from being applied because they're incorrect.When programming directly with CubeProgrammer, everything goes well (second image below), and we do indeed find the 0x00s. But this means that debug tests will no longer be possible due to the erroneous data in Flash...I tested on CubeIDE v1.8.1, v1.8 and even the v1.17.0, but the same problem persists. A "monitor flash mass_erase" doesn't fix the problem. Everything seems fine when using CubeIDE v1.15.1 but the generated binary isn't the same.The incorrectly written data corresponds to the assignment of an ALIGN (third image below), which is enough to distort an entire verifi

In my task, a 3-axis accelerometer is connected to a 24-bit ADC. How should I transmit the signal data to Nano Edge AI? Should I send the raw data directly, or should I perform calculations before transmitting it? In version 5, how can I check the Emulator section like in version 3?  

I am attempting to deploy an sklearn RandomForestClassifier on a STM32H7 using ST Edge AI.I am using the following function to export the RandomForestClassifier to ONNX:My call to the stedgeai cli is:stedgeai generate --model ../Python/ml_model/rf.onnx --optimization balanced --binary --address 0x91A00000 --target stm32h7 --name aq_network_rf --workspace ../Python/ml_model/workspace_rf --output ../Python/ml_model/output_rf When I subsequently perform inference, the results do not match my python tests.

I'm trying to calculate if I need an external resistor with my HSE crystal (24MHz, 18pF, 50R) but the suggested formula example does not give the shown result. So is the formula or the result wrong or have I misunderstood something?Below example from AN2867: An initial estimation of RExt is obtained by considering the voltage divider formed by RExt and CL2. Thus, the value of RExt is equal to the reactance of CL2.Therefore, RExt = 1 / (2 π F CL2), and so, with an oscillation frequency of 8 MHz andCL2 = 15 pF, we have RExt = 1326 Ω. If I put the values mentioned in the formula I do not get 1326R??   

Hi,I made some custom PCB's with a STM32L476RG. Here are some of the features:-USB-C connector (CC channel configured as device) with DM/DP routed to PA11/PA12.-Step down converter 5V (VBUS USB) to 3.3V (VCC for most components)-Tactile switches for BOOT and RESET-10 Pin SWD Debug header: SWDIO/SWDCLK -> PA13/PA14. SWO not routed.-no external crystalsI soldered one PCB up and checked the connections under the microscope and with some resistance measuring. So that should be fine.Now to my problem: I cannot flash or debug it. What I tried so far.-Using the bootloader via USB doesnt work. The MuP doesn't even show up in the device manager.Using an ST-Link from a Nucleo-L476RG board:-Run / Debug with CubeIDE gives error: "Could not read registers; remote failure reply 'E31'". When trying different debug settings and pressing RESET and/or BOOT while trying to debug sometimes gives different errors.-Trying to flash with CubeProgrammer gives warning "Warning: The core is locked u

Hi,I'm designing a PCB using H755, and the corresponding Nucleo's reference design is a helpful resource that I've been looking at closely.I'd like to support supply config modes 2 & 3 on my board but would prefer to do this using jumpers rather than solder bridges, adding/removing resistors or changing capacitor values: all these being needed on the Nucleo. Although these component changes are simple enough, I'd like an approach that's more convenient and less likely to result in damage to the board if the cycle is repeated a few times.Referring to the schematic MB1363 and Nucelo reference manual UM2408, I've highlighted the changes that need to be made when switching from config 2 (SMPS only) to config 3 (SMPS cascaded with LDO):My proposed variant on this is:Replace R35 with a jumper, placed as close as possible and with short traces to VCAPn and VFBSD.Replace R34 with another jumper, similarly using short traces and placements.Replace SB75 & SB76 also with jumpers, short tr
