Hi all, We would like to perform write/erase actions in internal flash during active BLE connection for a slave/peripheral device. We intend to use BLE_RfWithFlash example. We are trying to establish sufficient conditions for a slave to perform write/erase operations.Looking "4.7 Flash memory management" of AN5289, we see the constraints:BLE connected: the connection interval must be longer than 25 ms + packet length, tobe able to execute flash memory erase operation.Data throughput use case: When data streaming packet is sent, the radio is kept activeto send as much data as possible between two connection intervals. Therefore, theradio can not be in idle long enough to fit an erase operation. When the device ismaster, it can reduce the Connection Event Length parameter (with either theaci_gap_create_connection() or aci_gap_start_connection_update() command) toprevent the device filling completely the interval between two connection intervals.When the devi

Hi,I have setup the ADC in STM32H753ZIT6 to sample 4 channels with DMA in circular mode. This works as expected and I can check the values being updated in the "Live Expressions" tab.But there is an offset, which I can only get rid of, if I perform the calibration of the ADC each time I start the ADC.The reason I start the ADC and calibrate again, is that seems to be the only way to get correct results.  The DMA is setup to circular mode, so normally the ADC would only be started once. But as explained, this leads to an offset on all ADC values of some 0.05V.Any help is appreciated. Thank you.   uint16_t ADC_result[4]; while (1) { HAL_ADCEx_Calibration_Start(&hadc2, ADC_CALIB_OFFSET_LINEARITY, ADC_SINGLE_ENDED); HAL_ADC_Start_DMA(&hadc2, &ADC_result, 4); }   

Hi I can't find USB device with MTP example.Is there any resource about USB device with MTP?

Hi,I am using a STM32L452RET6. How do I generate spread spectrum PWM on that particular micro?I read somewhere it has a dedicated mode but did not find where.Is there perhaps a library specifically for it?If it does not have a dedicated mode or peripheral for spread-spectrum, how do I generate it in other ways using the standard PWM channels?Thank you :)

Hello.I'm working on the stm32h753vit6 MCU trying to integrate the X-CUBE-AI software package into my project and I noticed a couple of issues.1) After installing the package, I go into the IOC and as soon as I enable the X-CUBE-AI, the RCC_OSC_OUT pin reverts to the reset_state for some reason.2) Also as soon as I enable the X-CUBE-AI, Changes start happening in my clock tree.If I set back the clock tree to the configuration it was before enabling the X-CUBE-AI, My code crashes at the SystemClock_Config method (The method is autogenerated and I don't make any changes to it).Has anyone come across a similar issue?Thank you in advance, Yonatan.

Goodmorning, I have a problem with the validation on target of a CNN network on XcubeAI.I tried to validate the networks on desktop, and it runs, but, when I try to validate on target it gives me that error, I ask you if someone has a solution or something else to try to fix this problem.I'm using version 1.15.1 of STMCUBEIDE and v. 9.0.0 of cube AIthe board I try to validate is UFBGA144. Building project Generating project Temporary project loaded Temporary AI configuration done Generating temporary project code Building project C:/ST/STM32CubeIDE_1.15.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_1.0.100.202403111256/tools/bin/arm-none-eabi-gcc -c -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard  -DDEBUG -DUSE_HAL_DRIVER -DSTM32L4R9xx  -IDrivers/CMSIS/Device/ST/STM32L4xx/Include -IDr

Hello, I have configure ADC to use channel 5 and 6 but I am not understanding what I am doing wrong to get readings from the two channels. Here is my code:void adcConvertionFinish(ADC_HandleTypeDef* handle); static ADC_HandleTypeDef g_adc; static const uint32_t g_shutter_pin = GPIO_PIN_5; static const uint32_t g_window_pin = GPIO_PIN_6; static adcPowerMeterConvertionFinishHandler g_adc_conversion_finish_handler = NULL; static void* g_adc_convertion_finish_obj = NULL; bool adcPowerMeterInit() { __HAL_RCC_ADC1_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENABLE(); GPIO_InitTypeDef init_struct = {0}; init_struct.Pin = g_shutter_pin | g_window_pin; init_struct.Mode = GPIO_MODE_ANALOG; init_struct.Pull = GPIO_NOPULL; HAL_GPIO_Init(GPIOA, &init_struct); ADC_ChannelConfTypeDef config = {0}; g_adc.Instance = ADC1; g_adc.Init.OversamplingMode = DISABLE; g_adc.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; g_adc.Init.Resolution = ADC_RESOLUTION_12B; g_adc.Init.SamplingTime = ADC_

Hi,I am working on automating the build process of the ST firmware and for that I was looking for CLI tools which can be used for the same. I found that STM32CubeCLT is a toolset extracted from STM32CubeIDE, so I was trying out the toolset to check if it fulfils my needs. For development purposes we use STM32CubeIDE.To check if same hex file is generated, I built the firmware to generate the hex files using the STM32CubeIDE and STM32CubeCLT and calculated the sha2556sum hash of both the files. It turns out that both the hex files return different hash values.Is there any specific reason for this? I checked the commands executed by both the IDE and the CLI tool and the commands are same as far as I can tell. Note that I did clean build both the times(i.e. for CLI and IDE).Also I have noticed that there is no user manual/reference document for the STM32CubeCLT toolset except for the quick start guide. So I used the command mentioned in the quick start guide to build firmware using C

Hello,is there any example how to configure LTDC device tree entry for RGB display ?Documentation is unclear on that, only MIPI mode is quite well documented.RegardsArkadiusz

I want to read ADC values from 2 joystick. My aim is design a controller RC. I use stm32f103 and set up ADC1 with channel 0,1,2,3. I used interrupt but it read only one channel. Can you help me how to read 4 channel?Thank you! 

I'm a noob to the 32-bit world trying to add EEPROM emulation to my ToF application. I read AN3969 and downloaded the associated code, then added eeprom.c and eeprom.h to my project. That didn't compile due to typedef FLASH_Status missing amongst other things. Looking at some other posts, I learned that it is defined in stm32f4xx_flash.h which isn't included in the download but I was able to find on githib. Added it to the project and #included it in eeprom.c, now get even more errors, including in some of the hal .h files.It seems that the code associated with AN3969 is only half the solution. Please could someone offer some guidance?

Do the SPI interface need an entry in the SCMI file, as what I2C requires to work ?if yes, So far could not find the exact entry for SPI2. According to the SCMI wiki not, but you never now. (:-))  

Kernel tree does not assign any driver to pin PZ2. After gpioset -c gpiochip11 2=1, the pins goes actually high (from low) but the gpioset program stalls.

I am trying to get 12V at the output of STKNX buck converter, but I am not getting it and the STKNX dead.The RFB1 that I am using is 33K Ohm and the RFB2 is 3k Ohm, with these resistors the Vout would be 1 + 33k/3k = 12V. The maximum value of this voltage, that I got, was 9.46V while I was using RFB2 as 3.9k Ohm and if I use 3.24K (Vout = 1 + 33k/3.24k = 11.18V) the STKNX dead.Does anyone know where the problem would be? I saw in the datasheet that the STKNX buck output could be up to 12V. Do the resistors have any limit value? 

Hi,I'm looking into using the STM32WB55 device for a custom radio solution.From what I gather this same question was asked and answered here: https://community.st.com/t5/stm32-mcus-wireless/is-it-possible-to-flash-a-custom-application-to-cpu2-m0/m-p/288448Since the post is 4 years old I just want to make sure this is still relevant and that its not possible to make custom binaries for the M0 coprocessor due to encryption key managed by ST?BrJohan

Hello, I have a trouble when I tried to change AMP I2C adreess on AVAS EVK which is based on AEK-MCU-C1MLIT1(https://www.st.com/en/solutions-reference-designs/sl-ssasf011101v1.html ) like the below. 1. In Allocation pin page, I just do "Delocation" and then "Allocation" without any action.2. After Compile and download, the Amp doesn't work even though it worked very well before.3. When I checked pinmap, the pin map was changed.  - Before - After(Only Blue parts are same with before....) I don't know why the pin map is changed. How to avoid this?? Thanks,

Ok, so I tried to follow https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Getting_started_with_USB-Power_Delivery_Sink for an example on how to use STM32G0B1 family as a simple USBC Power delivery sink. The Article seems to have received an update on June 2024 so it suggested to be rather up-to-date. Unfortunately, lots (!) of things have changed when I try to reproduce the settings that are done in CubeMX in the Tutorial. For some settings I am quite sure that I found the "correspondence" in the current version of CubeIDE/CubeMX but with others, one is really lost because settings or variables just don´t exist anymore or new ones were added. It makes not even sense to ask for all of these here, because really a lot of different things in different tabs or sections have changed. If the Wiki should allow a more or less useful "getting started" approach, this is really broken. Has anybody followed the guide with a more of less recent version of the G0 FW Libs and a more or less recent C

A high-frequency DC testing power supply product that uses LM235 to measure the temperature of the heat sink (aluminum), and the measurement circuit is shown in the above figure:The temperature range of the radiator is also within the temperature range of LM235 (TO-92/-40 ℃,+125 ℃). The product is placed in a high-temperature box for 40 ℃ full power aging test. The maximum temperature of the aluminum heat sink is about 90 ℃, and the aging test time is 6 hours;During the aging process, if the temperature value detected by LM235 (voltage between measurement positions ① and ②, refer to the circuit diagram) is about 20 ℃ higher than the actual temperature (aluminum radiator), it will cause the product to have a false alarm (HOT-ERR);Question 1:This temperature measurement circuit has not been adjusted in any way, and LM335, which has been used for 23 years, has basically not had this problem; Recently, there have been multiple instances of LM335 being damaged, and now replacing it with LM2

Hello, I've been trying to port over ST OpenBootloader for use with an STM32L431KBUx over CAN. I specifically want to use CAN pins PA11 and PA10 as those are what are available in the package I chose. As I am porting over the ST Openbootloader code found here: https://github.com/STMicroelectronics/stm32-mw-openbl I noticed a few strange things:1. there is no can_interface file set so I had to write my own2. the project calls for app_openbootloader file set but those do not exist in the project so I grabbed it from an example project. I am also following this application note: https://www.st.com/resource/en/application_note/cd00264321-can-protocol-used-in-the-stm32-bootloader-stmicroelectronics.pdf Anyway, I got past these issues no problem. The issue I am running into now is when I try to connect my STLink V3SET to the STM32L431 over CAN using STM32CUBEProgrammer. When I hit connect, the program sends over CAN STD ID 0x79 with no data. My code will se

 Hello everyone,I'm working on an in-application firmware update for an STM32H7 series microcontroller. The process involves erasing and then writing to the flash memory. I can successfully erase bank 2, but I'm encountering an issue when writing to the flash.Issue Description: After the first 256 bits (flash-word) are written without any error, the subsequent write operations result in an inconsistency error.
