Hi,From the following repo https://github.com/STMicroelectronics/st-mems-android-linux-sensors-hal/tree/masterI would like to know if the driver it's compatible with an Android environment under snapdragon where all the sensors part is managed under the ADSP and the SSC core library. On this systems the sensors part is managed trough the SSC Framework who handles the sensor core functions.Does anyone have experience with it or know if it is compatible?Thank you.

I'm working on a custom board with a F446RET6 and testing through some code bits. I've been able to successfully test that the board programs and functions with a led-blink style program. My problem is that I'm attempting to use CAN2; I'm trying to test via loopback but I'm having issues getting any type of IRQ for a receive. I feel like its something basic I'm missing here but after reading through some other posts I'm either brain-dead or missing something.currently using the HSI clock but I wouldn't think that would matter for loopback testing (understand for the "real" thing would be best to use the HSE).RX GPIO is set to pull-upVerified (after looking at some old posts using an older version of Cube) that the CAN1 clock is being initializedAlso I understand that the "CAN2" device is really the "slave" to CAN1. I've got my slave start for the filter set to 14 to split everything half and half and just arbitrarily chose bank 15:   hcan2Filter.FilterActivation = ENABLE

Hello, i am trying to interface TI's ADS8910 (18bit SAR ADC) to an STM32F730 via normal SPI, since i am unsure whether QSPI will work.I want to achieve the full 18 bit @1MSa, which is possible when working with 54MHz (/2 APB2 prescaler on the F730 which runs at full speed - 216MHz) and the ADC's zone 2 transfer. The HAL implementation of dma transfer is way to slow between consecutive readouts and thus gets stuck "busy" and "locked" forever after the first readout. Therefore i am currently trying to write everything myself. My question is regarding the SPI CR2 register, bits 6 & 7 (RXNEIE and TXEIE):Will the DMA requests, mentioned in Bits 0 & 1 (RXDMAEN and TXDMAEN) still be generated when the interrupts are masked?I don't want my program to be interrupted more than neccessary. the flow should be :F7 gets an interrupt that signals that the ADC has finished conversion and is ready to send the new data.SPI transfers 3x 8bits // or 2x 11bits (the ads 8910

Hello,I'm working on a cutom made board controlled by an STM32F303ZET, I figured out that I forgot to pull up D+ for USB communication, even doing it externally keep showing me this error. I tried to pull up the D+ using 3.3V directly and also by pulling another pin HIGH. How can I resolve this problem ? 

I have an eval board (Nucleo STM32U5A5) working with the CDC_ACM demo code (UCPD/USB_HS, which was written in 2021). I then created the CDC_ACM from scratch with the majority of IOC parameters's configuration copied over from the demo IOC and MOOC tutorial (for STM32H7xxxx); I noted many new parameters in the 2024 release, which I left untouched. I then copied over some USB code filename (using WinMerge) into new code (as suggested by MOOC for STM32H7xxxx). I refer to this as a new code/project. I found an issue with the static HAL_StatusTypeDef USB_CoreReset(USB_OTG_GlobalTypeDef *USBx); it times out after the core reset: CSRST is not cleared in the new code. However, the demo code does.  I have checked the RCC/PWR/USB/UCPD register flags (via SFR window) while under the breakpoint in USB_CoreReset and found all the same between the demo code and new code except the TYPEC_VSTATE_CC2 which shows 1 in the demo code but 0 in the new code.  I have reviewed the datasheet and manu

Hi, I have a question to the ST community. I'm currently working on a project including an ECU form a diesel engine. The ECU uses J1939 for communication. I need to be able to read messages en send to the ECU. To do that I'm using an STM3210E-EVAL. Is there a library or stack available to use with my STM32 board? I did look on the internet where I found some things, but is nog for my board or incomplete. I hope that someone can send me in the right direction. If you need more information feel free to ask. I'm new to the STM32 platform.

Hello,I am new to dual core processors. I was working on both cm4 and cm7. My main core was cm7. I accidentally disabled the cm7 core on Stm32CubeProgrammer and now I cannot connect to the board. Power comes and goes instantly.  (I normally use STLK to connect the board.) What can I do to make my board work again?

Hello everybody,for first time flash programming of private CAN bootloader i want to use the ST bootloader.Despite of the nBoot_SEL Bit i can flash data if the flash is empty.The bootloader mechanism is shown in Figure 55 in the AN2606.Now the questions :1. Do i have to set valid level for e.g the RXD pins of UART 1 and 2 and 3 or are the internal pullup R used ?2 During scan of all possible interfaces, see Fig. 55 in AN2606, are the corresponding output pins (e.g. TXD pins) of the interfaces in Tri-state ?E.g. UART3 is used for flash update, is it possible to use TXD of UART2 for input, that means an external driver circuitdrives into TXD of UART2 ?3. If i use FDCAN, do i have to use FDCAN1 (PD0 and PD1, AN2606, Table95) or FDCAN2 (Manual, 2.5, page68, pins ?) ? Thanks in advance,BR, Kai

Hi，I have two questions about the SPAD:1: How does the L4CX select which part to turn off and which part to turn on when the signal is so large that the SPAD needs to be scaled down? Because i have a Lens installed on the light receiving area,  I'm worried if the spad  turn off  the signal-sufficient part .2: Is it possible to adjust my SPAD area by ROI? The manual of the L4CX says that this function is not supported, but I found the API function . Below I would like to explain the problem I'm having:In order to increase the  signal at the far end, I installed a spotlight lens on the light receiving part.I then noticed that when detecting the appearance and disappearance of white objects in close distance, the data returned by the L4CX was not very stable, with continuous error reporting and data abnormality.I found that when the anomaly occurred, both the signal and the spad were abnormal, so I suspect it was caused by the spad opening position.I've

Hi, ST community.I'm trying to drive a motor using Nucleo-H503RB. At that time, I am trying to change the USART pin of STLINK and connect it to Motor pilot, but it does not connect.＜Detail＞I want to use PB14 and PB15 for the STLINK USART pins instead of the default PA3 and PA4 (because I use PA4 as DAC).I changed the Nucleo-H503RB json file for Motor Workbench and solder bridge (SB2&SB3→SB18&SB22, SB19&SB33→SB20&23) to change the USART pin. In Motor Workbench, the USART pin has been changed from USART3 to USART1. However, it does not connect to Motor pilot.（Defalut setting (PA3 and PA4) were worked correctly. ）The software I use to generate F/W is Motor Workbench 6.2.1,  EWARM V8(but debug in V9), CubeMX6.10.0, STM32Cube_FW_H5_V1.1.1.I will send you the Workbench file, json file I was change, and EWARM F/W file that I used.  

Hello everybody, I am currently designing a configuration utilizing two drivers to heat a mat, which is a resistor load requiring 24V and 3.3A. This component is commuted at 100 Hz. For this setup, I've employed two different drivers: the first one being VNB14NV04TR-E, utilized for switching large loads requiring high currents. On the other hand, I've utilized the MIC5018 to control the spoken driver. Additionally, I have add a pull-down resistor to force the 0 state, and I may use a series resistor for the PWM signal to limit the current, although I am not sure about it.... We have conducted tests of this configuration on one STM developmentboard, and it appears to be functioning properly. However, we would like to confirm if the setup is correct, as we have connected this system to a developed PCB with STM32h563, resulting in sparks and the MCU failure. The diode is a recent addition to the design; initially, we believed it might not be necessary due to the resistor load, assuming th

Hello community, I am using STWINKT1B board and trying to implement basic accelerometer datalogging from scratch. I don't want to use HSDatalog because I don't need so many functionnalities.I am using FATFS functions, able to use mount, mkfs, mkdir, open and write functions to create this file DATA/data_000.TXT.When I add the f_stat (after mount and mkfs) function with the path "DATA/data_000.TXT" and restart the board, I always get a FR_NO_FILE error. If I put the SD card in my laptop I can see the file in DATA/data_000.TXT:Here is my code:Any idea about what could cause the issue ?Thank you 

I am developing a device with the STM23MP153C and plan to implement secure boot, but I don't fully understand the SSP workflow and have a few questions.1. The STM32CubeProgrammer documentation says that the -ssp command can be executed both with HSM and with a generated license. Do I understand correctly that this is the license that must be generated by the -hsmgetlicense command of STM32CubeProgrammer? If so, the license is valid only for the current device?2. Is it mandatory to have HSM in production? Is it possible to generate a license for production so that production is not dependent on the presence of HSM? STM32CubeProgrammer program has a command -hsmgetlicensefromcertifbin. Is this command not what I want? If so, it requires "Input certificate file path" as an argument. How can I generate it?3. HSM has a certain licenses count. Is this license per flash process or per device? Can I flash the same device multiple times with one license?

I have one of P-Nucleo-WB55 and recently bought one more P-Nucleo-WB55 board.We are using this board to program the STM32WB55VG6YTR microcontroller in our custom board and we have succeeded more than 20 times in programming that microcontroller using ST-LINK in P-Nucleo-WB55. However, recently we couldn't access either our microcontroller in the custom board or the dummy microcontroller in P-Nucleo-WB55 anymore. In addition, we never succeed in using the new P-Nucleo-WB55 board. After several trials, we found that the wire length of SWCLK was the reason.Right now, we only can access the dummy microcontroller in P-Nucleo-WB55 using a jumper pin to connect SWCLK. If we use a normal wire (resistance < 1 ohm), we cannot access even the dummy microcontroller.This problem is big because we have to program the microcontroller in our custom circuit board. Does anybody have a similar problem and find a solution? 

Hi people, I'm trying to use the flash crc but is not working as expected. If I pass the end address with offset 3 or 7 the result of crc calc will be always the same, 0xba4bbbf0.

good morning   i was trying for sometime now to configure stm32 timer as a counter to count the pulses in order to count the RPM of a rolling gear and then show it on a lcd screen, and no matter what i do or change in the code or the timer configuration, the number of pulses is always stuck at 0. can anyone please help me with it? i really need it for my studies. (by the way, i am using a proteus simulation to test it).
