Hi, I am new to STM32. I have a STM32H723 nuncleo board where I want to sample 8 bit data from the on-board ADC at the maximum frequency of 3.6 MHz. Then I want to directly transfer the data to a SD card using DMA with SPI. Preferably I would want to add a timestamp to each sample, where this can get tricky to combine with the use of DMA.ADC -> Memory + adding timestamp (As a buffer)Memory -> micro SD card I need some tips and tricks how to do this, and if it is even possible to do at these speeds.Thanks for all answers!

In the STM32L562 reference manual (RM0438), v7.0, the section 11.6.13 "GPIO register map" is missing the registers MODER and PUPDR (which are documented in the preceding sections).

Is it possible to transfer large data files, meaning bigger than the internal memory of the tag?The intended purpose is to have a stm32 connected to an i²c dynamic tag and be able to write large files, like a new firmware, to the stm32 MCU. The problem is, that I couldn't find documentation if it is possible to simultaneously read the data via i²c which is currently written to the tag via NFC. If not possible in a continues stream, reading in chunks would be a viable alternative. As long as it is possible to do in one NFC "Session". That would allow a 0 port device that can be sealed towards the environment. 

Hi Team,We are using LD1086DT33TR regulator to generate 3.3V output from 5V input, But the the maximum dropout voltage given in the datasheet is 1.5V.Our dropout voltage is 1.7V (5V - 3.3V =1.7V) which is exceeding the max dropout voltage of the IC mentioned in datasheet ,My question is whether this IC is suitable for our requirement or we need to look for alternative.RegardsTejas

Hello,I'm planning to use the STM32G474 to read a pulse width. This width is a delay value in nanoseconds.I'm wondering if there is any possibility to use the High resolution timer (HRTIM) for that operation.I would use the events to trigger a rising (set the timer) & falling edge (reset the timer) and then read the value to get the width (delay) of my pulse signal.If anyone has an idea, it could be helpful :)Kind regards,Chris

Hello, i am working on the STM32MP157C to use its ADCs. at first i was only using the iio framwork on linux , however it is limited. so i'm trying the examples on the (github page) using the Linux Remoteproc . my board configuration is different since that i'm using OSD32MP1-brk. I am using the SWD to debug the MPU using ST-link V2 as shown in the figure 1.Figure1: ST-LINK V2 USB Dongle ProgrammerNow after compiling the code and Loading the compiled ELF firmware in the remote processor memory using the cube mx ide and the provided shell scrip in the example it seems to run without issues. how ever i have no indication of what the ADCs are doing, with the debugger i was only using engineering mode to compile and load it to the M4 but then linux isn't running so the variables are showing empty... I don't know if i'm doing the right thing or not since i'm not using the development board that was originaly used for the examples. since that i have i different pin mapping in the device

Is there an example or link where I can see the code for STM32F407IG Ethernet (UDP) communication?https://www.st.com/en/embedded-software/stm32cubef4.htmlI tried LWIP (UDP) communication by looking at the example in the link, but can you tell me why it doesn't connect?Error : lwip.c -> ethernetif_set_link(&gnetif);  An error occurs in this part. Could you please tell me a function or method that can be used instead?

Does a product that includes a ST25DV need to meet the requirements of the Radio Equipment Directive 2014/53/EU I have developed a product that has a ST25DVKC included. I am looking at the compliance necessary to put this on the market. I have 2 "Test Houses" that give me different opinions on the need to comply with RED. The question seems to be over whether the ST25DVKC is classed as a "Passive Tag" or not. Can anyone give me some clear guidance on this?

I am using the SBSFU STM32CubeExpansion_SBSFU_V2.6.2 version for my custom board STM32H743VI controller. I have ported the STM32H7B3I-DK project for H743 controller for COM port and changed the crypto scheme to SECBOOT_ECCDSA_WITHOUT_ENCRYPT_SHA256. I am getting below logs and hangs. It hangs in the below code,SE_ErrorStatus SE_VerifyHeaderSignature(SE_StatusTypeDef *peSE_Status, SE_FwRawHeaderTypeDef *pxFwRawHeader){ SE_ErrorStatus e_ret_status; uint32_t primask_bit; /*!< interruption mask saved when disabling ITs then restore when re-enabling ITs */ /* Check if the call is coming from SFU code */ __IS_SFU_RESERVED();#ifdef SFU_ISOLATE_SE_WITH_MPU if (0x0U != SE_IsUnprivileged()) {  TRACE("\r\n inside privilege");  uint32_t params[1] = {(uint32_t)pxFwRawHeader};  SE_SysCall(&e_ret_status, SE_CRYPTO_HL_AUTHENTICATE_METADATA, peSE_Status, &params);  TRACE("\r\n after secall"); }After SE_SysCall() call,

Hi there!   We are developing a new STM32WL based product that must be compatible with the existing STM32L0 + S2-LP products.   It appears that the GFSK data whitening algorithm is different(?). I used an SDR dongle to sniff the raw bytes transmitted over the air.   A 4 byte packet is transmitted with the following content (in HEX; before data whitening): PREAMBLE: 55 55 55 55 SYNC: 93 0B 51 DE LEN: 04 DATA: AA BB CC DD   The packet transmitted over the air by the S2-LP is (after data whitening): PREAMBLE: 55 55 55 55 SYNC: 93 0B 51 DE LEN: FB DATA: 4B A6 56 30   The packet transmitted over the air by the STM32WL is (after data whitening): PREAMBLE: 55 55 55 55 SYNC: 93 0B 51 DE LEN: FB DATA: 2D 03 95 6A   So the LEN field is correct but the DATA is different. I have looked at section 7.10 of the S2-LP datasheet and section 6.2.3.4 of the SX1261/2 datasheet but can't figure out the difference.   The STM32WL whitening seed is set to 0x1FF (alll ones) w

Hi,I am using STM32H747. I have successfully write&read micro sd card over SDMMC2 peripheral while debugging. But after debugging, when I power cycle or reset the board, I am not able to use sd card. I see FatFS open file failing. The board is arduino portenta H7, which has its own custom bootloader, so I flash my code on address 0x08040000 and it boots ok. I use CubeIDE. The only thing which does not work after reset is SDMMC strangely. Anyone has encountered this issue?Best regards

I am trying a PWM output with jumper connectors.when mains fail(input supply)PWM is on indicated by a lamp and OFF when there is a supply .in between if the supply is OFF and Lamp is in ON there is a jumper connect to PA6 (input)of stm32c011f6p6.if the input is set to 1 it should make the PWM with half duty cycle.I couldn't understand that my half duty cycle part is blinking once the input supply OFF and PA6 is set till the input supply is 0.1 and below 0.1 its getting stable half duty cycle. can one find the error I made please. Mains is input supply 1.5v Vbat is 0.9v 12 Mhz internal clock can one find the error I made please. if (Mains > 0.1) { if ((Mains < 1) && (Vbat > 0.9)) { TIM1->CCR4 = TIM1->ARR; HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_4); Set_LED(0); //Batt_Chrge(0); HAL_Delay(100); } else if (Mains > 1) { TIM1->CCR4 = 0; HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_4); HAL_Delay

Still trying to get a custom board with a STM32MP151AAC and 512MB ram to boot from eMMC. Switched to using this guide.After various new issues (one of them being this), I managed to bitbake a set that I'm able to fully program with CubeProgrammer.However, that was the only good news about that. The board doesn't boot from eMMC, instead i get the following output.NOTICE: Model: STMicroelectronics custom STM32CubeMX board - openstlinux-6.1-yocto-mickledore-mp1-v23.06.21 INFO: PMIC version = 0x21 INFO: Reset reason (0x15): INFO: Power-on Reset (rst_por) INFO: FCONF: Reading TB_FW firmware configuration file from: 0x2ffe2000 INFO: FCONF: Reading firmware configuration information for: stm32mp_io INFO: Using EMMC INFO: Instance 2 INFO: Boot used partition fsbl1 NOTICE: BL2: v2.8-stm32mp1-r1.0(debug):lts-v2.8.6-dirty(ff0bd5f9) NOTICE: BL2: Built : 17:57:15, Apr 21 2023 WARNING: Failed to access image id=3 (-2) ERROR: Unable to find a metadata partition WARNING: Failed to set reference to ima

On STM32MP1 discrete power.  512MB DDR , TF-A & OPTEE configure in SYSRAME/TC:0 0 Panic at core/arch/arm/plat-stm32mp1/cpu_opp.c:106 <set_clock_then_voltage>Log attached.This message seems to unique for stm32mp1 in OP-TEE  code. no other platform source file seems to use this message.Looking further this cpu_opp.c file is not part of OP-TEE on github in ST's stm32mp1 , thus ST unique and added afterwards to the ECO system. Seems to be patch. So that anyone familiar, outside ST, with what this code is doing is probably zero. The source does not reveal much about what is is doing.

Hello,I'm developping a Zigbee firmware for a custom board embedding a STM32WB MCU. So I'm using STM32CubeMX application to configure my card and the Zigbee middleware. For some reason, I need to understand how the differents Zigbee functions work and unfortunately, I only have the header files. So, my question is : How can I obtain the Zigbee source files ?Sincerely, Evandzd

Posted on March 16, 2018 at 07:23I have been using ST Visual Develop with the STM8 Cosmic Compiler on a Virtual PC with Win10 for months.Now I want to use it on my normal PC (also Win 10 64 bit  Version 1709), CosmicCompiler is working but I cannot program the code on the target (see picture), this  happens a soon as I open in the menu Tools->Programmer.I installed the ST-Link utility and the ST Visual PÃœrogrammer, both can be started. The ST-Link V2 is correctly shown in the Device Manager of Windows.I re-installed ST Visual Develop but this doesn't help.Any ideas what is going wrong?

Hello, We have an audio amplifier circuit in our design using the TS482IDT chip. We're wondering if there's any guidance on what is a good value for decoupling capacitors for the chip? Is 0.01uF acceptable? Or Could we use 0.1uF?Thanks, 

I have a test project that sets up TIM3.3 to count microseconds between falling edges of the timer input.  The timer is started with a call to HAL_TIM_IC_Start_IT(&htim3, TIM_CHANNEL_3); to start timing the input.  Inside HAL_TIM_IC_CaptureCallback(*htim), I call pulseDurations[pulseIdx++]= HAL_TIM_ReadCapturedValue(htim, TIM_CHANNEL_3);followed by __HAL_TIM_SET_COUNTER(htim, 0); to save and reset the TIM3.3 counter. This gives me the number of microseconds between falling edges of the timer input. This works perfectly until the frequency on the input exceeds 10KHz where incoming pulses appear to be lost and are not counted.In an attempt to improve the high frequency abilities, I created a second test project to use  HAL_TIM_IC_Start_DMA(&htim3, TIM_CHANNEL_3, fallData, numData); to populate an array with the timer counter values every time TIM3.3 receives a falling edge. The array gets populated correctly, albeit the 16 bit timer value overflows but, o

Hello everyone,I'm working on a project with a STM32L072CBT6.I'm using LPUART (PB10 / PB11) at 9600 bauds to communicate with an other board.

Hi.I use the STM32G474.To start TIM1 synchronized with HRTIM, I will use "hrtim_out_sync".I have a question.If I use "hrtim_out_sync", Can I start TIM1 at same time and reset ?I want to set a same frequency for HRTIM and TIM1 and start simultaneously.In addition to, Please teach me how to set on CubeMX and HAL Lib. .

The STM32U5 has HS PHY and it's slower than the STM32H5 so why doesn't the H5 have HS PHY or any HS USB support? Will a version that does be released in future? Its almost the perfect chip to use for a future project I have in mind aside from the lack of HS USB support.
