I have the Nucleo-H743ZI2 board. It uses the STM32-H743ZI part which has a reasonably fast 16-bit ADC, or at least that’s how it is specified: https://www.st.com/en/microcontrollers-microprocessors/stm32h743zi.html3× ADCs with 16-bit max. resolution (up to 36 channels, up to 3.6 MSPS)When I am testing this board, running the ADC at about 58ksps in single-ended mode, the actual dynamic range of the ADC seems rather low to me. I have the ADC using DMA to fill a circular buffer. Using a 20-second period sinewave input, I see 2000 counts or more between max to min readings in each set of 4000 readings on what should be a nearly-DC value during that short 70 msec interval, only 0.3% of the sinewave period. Even when I use 8x oversampling to average 8 readings together, and actually connect the ADC input directly to ground, I still see about 120 counts of noise. So considering the full-scale range to peak-to-peak noise, this so-called 16-bit ADC looks to me like it provides less than 10

Hello,I have a project where one of the requirements is to activate the iwdt in some defined circumstances, and refresh it in other circumstances also defined. I need to collect evidence of the correct implementation of iwdt in such a way that the acceptance criteria of these requirements are validated. (And the code can not be modified during the test to put some while(1) that makes iwdt to be triggered, or add some function pointer to a non valid address. The code must be validated as it will be flashed in the product).I had thought to force a hard fault using the STM32CubeProgrammer. Is it possible? Is it possible for example to make the program jump to a not allowed address (e.g. set the PC register to 0x0000000000) to force a hard fault on request to test the iwdt? The idea is to automate the tests, so being able to do it using the cli commands of the STM32CubeProgrammer would be a great help.Thank you very much in advance.

I'm trying to implement a RTC using the LSE crystal of Nucleo-h743zi board (Rev.B model). In addition, I want to backup the timestamp in case of power loss. Following the reference and user manuals, I finally have my RTC worked, using RTC backup registers and a external battery connected to VBAT (unsoldered SB156 and enabled mcu internal charger). So far so good. Unfortunately, after a couple of minutes I realize that RTC loses about 1 or 2 minute. This fault is getting bigger and after 24 hours this fault is about 1hour.I use the RTC as an internal clock and I don't use tamper or wakeup pins. I have also read the errata sheet and I think there is no any conflict or interference with other pins or functions. If I choose to work with the LSI crystal, the aforementioned problem is not occurs. But in that case the backup function doesn't work. It is worth mentioning that the RTC has the same behavior even if I run any of the STM32cube examples pertaining to rtc.Furthermore, I tried to mea

Hello,We are researching the feasibility of a new product and have some questions regarding STMicro's TOF sensors. At this time we are narrowing on the VL53L4CX, but I am sure these questions apply to most of these sensors. The product is detecting distance of a flat, white, square coupon normal to the sensing field. About three inches by three inches. The questions are as follows:1. It seems like ambient light has the most dramatic effect on range of the device. Does it also dramatically effect measurement repeatability and accuracy? As a result, are these sensors generally not used outdoors? Is there a way to compensate for the effect of ambient light?2. The size of the full visual field for these sensors, even with a 18 degree FOV, gets pretty large past several feet. Is there an understanding of how much of the visual field an object needs to take up for it to be detected? For instance, can a 3inch by 3 inch test coupon be detected at 3 meters, neglecting the effect of am

We have recently received source code from the company that was developing for us. This is our first time using a STM product, so we have some learning to do. We had them build a custom external loader and bootloader in addition to the main application. I have attached an image of the three projects. What is the correct way to build and deploy each project onto a clean board with no code on it?

Hello, I try to setup a working example of UAC1.0 USB to I2S - stereo 48kHz 16 bits on a stm32F4 discovery card (with CS43L22 CODEC). I try to get the project developed as far as possible on existing code from ST:STM32CubeIDE generated code,The board Drivers/BSP code for the audio part,inpiration from audio stand alone examples from other F4 boards.But this is not working correctly: bit of part of music with cracks and noises. With a Logic Analyser (LA), I looked at the I2S and it is clearly wrong. There are variants, but basically, it stammers. Instead of 0x0000, 0xDE1F, 0x0000, 0xCA... it gives something like 0x0000, 0x0000, 0xDEDE, 0xCACA, 0x0000, 0x0000. Please see attached snaposhots, with buffer content after breakpoint at usbd_audio.c Sync function, and the corresponding Logic Analyser capture. Values correspond between with Dec=> Hex conversion, except the "stammer". I have the record and playback example working, from USB board. I normally use the same BSP and board drivers

Hi everyone, I have questions about thread network protocol on STM32WB series mcus.When using open thread protocol in STM32WB series processors, the device can be configured as open thread border router (OTBR).In the same way, STM32WB mcu can be configured as end device.1- Let's configure one of the two stm32wb mcu devices as end device and the other as OTBR. Let's assume that we have an active end device and OTBR. Will these two devices be enough for me to control the end device from the mobile application? Does it need any other device like Leader, Router etc.?2- In this example, Raspberry pi is used as OTBR. Why was STM32WB not used? Does the OTBR device need to be an embedded linux device? https://wiki.stmicroelectronics.cn/stm32mcu/wiki/Connectivity:STM32WB_OpenThread_Border_Router_Application3- If the STM32WB mcu can be configured as OTBR, what is the number of end devices connected to this border router? Is there a maximum number of end device connections?  I

Hello,I try to build the STM32CubeExpansion_SBSFU_V2.6.2 for STM32H750B-DK.

Hello,Just got a new Nucleo-H563ZI board and I was trying to connect it to PC through the STLINK USB-C port, in order to play with it. I've checked jumper config, and all seems right, but the only thing happening when plugging in is that LD4 RED half is always on and the green half blinks. No other LED is on. If I change JP2 to power from CN13, plugging the same cable in the CN13 powers the board correctly, and the default demo starts running. I'm able to connect a Nucleo-F446RE and a Discovery board succesfully to the same PC port. I did search the forum, but I wasn't able to find some similar situation, so I'm out of ideas :)I wonder if I could power the board with a powerbrick through CN13 and use CN1 then for programming? Thanks and sorry if this was asked before.

Hello,I have an application that uses the TCPM/TCPC architecture, with a STM32U5 acting as the port manager, and the FUSB307B as the port controller. I want to use the USB-PD middleware stack for the policy engine, however, when looking at the available libraries, there is no USBPDTCPM_PD3_FULL_xxxx.a for the Cortex-M33. Are there any compatible TCPM libraries for the STM32U5? I do not want to use the inbuilt USBPD PHY, and only want/need to use the policy engine and port managing capabilities of the USB-PD library.Thanks

While looking at the HAL's RTC code, I noticed that in the IRQ handler for WakeUpTimer, there is no enabling of access to backup domain registers before clearing flag WUTF in RTC register ISR...Should this not be needed?When testing in my own implementation, WUTF flag cannot be cleared unless I first enable access to the backup domain registers.The reference manual (RM0090) does not feel very clear about if this is needed for clearing WUTF.(this is just one of numerous issues I have with the HAL RTC code and the documentation, but I feel that I may need to know more to determine if it's an error in the HAL code)

Hello.I want to integrate ADC with DMA, and calculate the average count of all convertions.I'm using the following code:In adc.c:```if(HAL_ADC_PollForConversion(&hadc1, 10) == HAL_OK) {uint16_t value = HAL_ADC_GetValue(&hadc1);USART_Send("%.3f", value);HAL_ADC_Start(&hadc1);}```In main.c:```HAL_ADC_Start_DMA(&hadc1, (uint8_t*) AVG_BUF, AVG_BUF_SIZE);``` However HAL_ADC_GetValue() seems to not use DMA.I want it to explicitely use DMA to read.

Hi, I am developing a project with an STM32H7 microcontroller, that has to do with ethernet connectivity. More specifically it is an embedded display that runs freeRTOS v2 code, which is being generated automatically from touchGFX. I used the cubemx in order to enable the ethernet peripheral,  the LwIP to assign a static IP address to my board, and also I set MPU configurations. After that, when I generate my code, I set a section into the linker script file (lwip_sec) and set the DMA descriptors to run in RAM_D2 also with the RX_pool buffer. I manage to succeed to work with the peripheral I can ping my board correctly, although at a random time it generates a precise hardfault error. So I would like to ask a question about linkerscript. Is there any additional process that it needs to be done in linkerscript (for example, change the length of ram or other things, when a new section is being initialized) in order to avoid the hardfault error, or it isn't related the linkerscript w

Hello. I am developing CAN communication protocols using STM32F429.However there is a problem in sending CAN frame data. Here is a picture which I captured in CAN TX using logic analyzer, and as you can see, the series of data is losted after first data.I tested this with publishing 100Hz, this problem occurred once a minute.In normal case, it should be like this. And also I add my code for helping to understanding.  __disable_irq(); motorCANTxMailBox = HAL_CAN_GetTxMailboxesFreeLevel(&hcan1); HAL_CAN_AddTxMessage(&MTRL_CAN, &motorCANTxHeader, &motorCANTxData[0], &motorCANTxMailBox); __enable_irq(); I disabled the non-automatic retransimission and enabled automatic bus-off feature.But I wonder why the retransimission did not occur.
