Hello.I try to use ADC with STM32H743II. The problem is that the calibration flag is not reset.//ADC1 RCC->AHB1ENR |= RCC_AHB1ENR_ADC12EN;   //Exit DEEP Sleep ADC1->CR = 0; while(ADC1->CR != 0) { ADC1->CR = 0; };   //Enable LDO ADC1->CR = ADC_CR_ADVREGEN; //dump delay, for LDO startup for(uint32_t i=0; i<0x10000; i++){ __NOP(); }; //Start CAL ADC1->CR |= ADC_CR_ADCAL; while(ADC1->CR & ADC_CR_ADCAL){__NOP();}; //Program stop here foreverThis code worked in another project. If remove the calibration, then the ADC works (I use 2 regular channel with DMA).Why can't the flag ADC_CR_CAL be reset?

Hello, Is there a lora library which supports the lora specification 1.1 available?What I found are 1.0.3 and 1.0.4. But I am looking for 1.1 too.Anybody can helps?

Hi!I am looking for a brushed DC-motor ±12V controller for higher currents, typically 25A-30A. I have checked the ST products Evaluation & Development Boards for Brushed Motors - STMicroelectronics but it seems the highest current available is 2.5 A. However, it does not need to be a complete dev board.I am considering to design something similar to Sabertooth 2x32 regenerative dual motor driver (dimensionengineering.com) that I can control with PWM from a STM32 MCU.Any hints?Thanks in advance

I want to understand how I could convert the sensor data on the box into real-time position tracking. The tracking is periodic linear movement in the y-direction going from a range max of 15/16 feet and back to 0. Are there any good resources or git-hub repos I can tap into?

Hello STM32U5 community,I was making a few attemps with my B-U585I-IOT02A demo board and TF-M. I am afraid I have irreversibly locked the MCU.Here is what I did:run regression.shset RDP level 1 with the Programmer despite the warnings, because I forgot that regression.sh had erased the Secure and NSecure applications.Now I fail to reconnect with the MCU by any means. What can I do? TZEN/RDP regression with boot from RSS? AN5347 says "a small rework" must be done. I would appreciate a step by step instruction.Regards.

In Bus -off condition , the ECU(node) disconnects from the CAN bus.So how it monitors the transfer and receiving of the message signal in CAN bus until Bus -off recovery stage is received.

The STM32F070RBT has Hardware Flow Control for RS485, with DEAT, DEDT and DEM bits in USART_CR1 and USART_CR3 registers.How do we identify which series of ICs have these features easily? Is it a particular series or type? The STM32F4 IC we are currently using does not have this option however it is not highlighted as different on the datasheets.

Hi all!I am testing the audio configuration for the stm32mp156C-Dk2, with lastest demo(4.0.1-openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15).I followed the sound card configuration [tutorial](https://wiki.st.com/stm32mpu/wiki/Soundcard_configuration) and I can't configurate correctly somes controls.E.g (Analog Playback Volume)root@stm32mp1:~# amixer -c STM32MP15DK cset name='Analog Playback Volume' '204','204' amixer: Control sysdefault:0 element write error: Invalid argument   root@stm32mp1:~# amixer -c STM32MP15DK cset name='Analog Playback Volume' '100','100' numid=3,iface=MIXER,name='Analog Playback Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=228,step=0 : values=100,100 | dBscale-min=-102.00dB,step=0.50dB,mute=0In this case, the max argument is 228 but when I try it with the value 204, it says: "invalid argument" but with other lower value it works...This also happen with others controls.What is the reason for this to happen?Regards!Thanks!

Hello,I am looking to use the NUCLEO-H7A3ZI-Q, which utilizes a STM32H7A3ZI MCU. It has the following memory specifications:2MBytes of Flash1376 kBytes of SRAMI am looking to do the following things on my product:1) LCD Display (480x272 resolution), potentially with animations (animations TBD. For this question, assume we are using animations)2) CAN communication3) Basic GPIO signalingMy goal is to minimize PCB cost, so I am trying to see if I can get away with no additional, external RAM/Flash. I am trying to determine if that is possible, but want to confirm my logic.For the SRAM, it needs to be able to display each pixel of the full 480x272 resolution. If we assume 1 frame buffer (no animation) and a 24 bit depth (RBG888), then the RAM requirement is:480 x 272 x 24 / 8 / 1000 = 391.68 kBytesIf I want to do animations (Basic TouchGFX screen transitions. Not anything fancier than that), then an additional frame buffer would be needed. Therefore, the needed SRAM is:480 x 272 x 24 / 8 /

Hi,I am new to STM32 and the Signing Tool and I'm trying to sign using a key from an HSM (nitrokey) but i get the following error:"Error loading pkcs#11 module functions".I run the following on Ubuntu 20.04:STM32MP_SigningTool_CLI --binary-image [path to stm32 file] --algorithm 2 --module /usr/lib/x86_64-linux-gnu/engines-1.1/libpkcs11.so --key-index 0x0 --slot-index 0x0 --password 123456 --output ./signed.stm32Any help appreciated!ThanksDoug

We teach using the STM32L476G Discovery kit Board. We have been using STMCubeMX 5.6.0 and Libraries 15.1. We want to migrate to current versions (6.6.0 and 17.2) but all of out programs that use the LCD controller fail. After some detective work, the bug appears between versions 6.2 ands 6.3. There is a file called stm32l4xx_hal_msp.c that is generated and some new code has been added:/** Initializes the peripherals clock */ PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_RTC; if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit) != HAL_OK) { Error_Handler(); }It turns out that this code was moved from main.c to stm32l4xx_hal_msp.c and in moving it one line of code was dropped. PeriphClkInit.RTCClockSelection = RCC_RTCCLKSOURCE_LSI;Without this line of code, the LCD/RTC clock selection is none. That's why nothing works. There is a workaround since there is a user area where this code can be placed. But - it is still a bug.How do I report this kind of bug and either get it ad

After enabling "generate peripheral initialization as a pair of '.c/.h' files per peripheral" under Project manager > Code generator > Generated files, everything stops working, including debugging log also does not show up in my tera term.How to regenerate this problem: (stm32wb55 ) Select the BLE_Custom example from the libraryAdd FreeRTOS in the ioc. file (Remember to set the TOTAL_HEAP_SIZE to 20480, Enable     USE_NEWLIB_REENTRANT  , change your SYS timebase source to TIM17) Go to Project manager > Code generator > Generated filesEnable "generate peripheral initialization as a pair of '.c/.h' files per peripheral" * There will be no issue if I did not enable the "generate peripheral initialization as a pair of '.c/.h' files per peripheral" but I feel that it is messy if I don't enable it.

In STM32CubeMX clock schematic and in the clock schematic of the reference manual CK_PWR is mentioned. It is never explained what it does and what it is for.I'd like to know what it is for and how it affects current consumption (since it is before the AHB prescaler).

In X-CUBE-EEPROM, the calculation of PAGES_NUMBER from NB_OF_VARIABLES is defined as:#define PAGES_NUMBER (((((NB_OF_VARIABLES + NB_MAX_ELEMENTS_BY_PAGE) / NB_MAX_ELEMENTS_BY_PAGE) * 2U) * CYCLES_NUMBER) + GUARD_PAGES_NUMBER)With a 2K flash page and a 32-byte header, 252 8-byte variables will fit in one page, as stated in AN4894. However, setting NB_OF_VARIABLES to 252 allocates an extra page.To get the correct number of pages it should be:#define PAGES_NUMBER (((((NB_OF_VARIABLES + NB_MAX_ELEMENTS_BY_PAGE - 1U) / NB_MAX_ELEMENTS_BY_PAGE) * 2U) * CYCLES_NUMBER) + GUARD_PAGES_NUMBER)

Hello.​I am using the stm32f051 discover board.I want to use RTC's WAKE UP function when I wake up in stop mode, is there a way?​The STM32F051 MCU must be used.

Hello!I am trying to use the STM32CubeProgrammer API to create my own application with a simple GUI in C++. Currently my solution is compiling the STM32CubePrgAPI as static library and then include it in a MFC project.Basically user clicks OK from the GUI and then Example2 is executed. The getSTLinkList function executes with no issues, but connectSTLink fucktion gives me this error.int connectStlinkFlag = connectStLink(debugParameters);   0xC0000005: Access violation executing location 0x0000000000000000.If I compile STM32CubePrgAPI as .exe, it works with no problems.What am I not understanding? Is compiling it as a static library a valid choice? What other options do I have?I can't find any examples of applications created using this API. Has anyone done something like this?

Hi everybody,I have a custom STM32 board. I'd like to use ANT7-T-ST25DV64KC dev board to use NFC functionnalities. I have red that I can use X-CUBE-NFC7 to communicate with this board.In my cube MX, I have choose custom/NFCTAG7, I can configure IC2/GPO. Then, when I generate the code, I have an error. Compiler told me that "st25dvxxxkc.h" is not in the directory.Is someone known where I can find this file ?Thank you.
