Hello guys,I was inspecting the design files of the Nucleo board and could not understand the use of the capacitor used for the TCXO. In the image attached (nucelo design schematic file), a note says that the C31 is used in order to avoid stubs on XTA path when the same capacitor is not placed. I don't understand what it means, could someone help please?

I am trying to run an FTPM in a trusted environment generated by OPTEE. I can see OpenSTLinux has support for OPTEE, TPM but there is no support for ftpm. Can someone give me pointers as how I can include ftpm in distro(openstlinux-weston). ftpm souce code is made available by Microsoft but I want to know how I can make it work on STM board.

Hello,So I already downloaded the Lorawan_End_Node example into my Nucleo board and I could see how it works with the TeraTerm terminal.However, now I'm trying to generate a new code from the .ioc file with the CubeMX (I only added the debugger option and defined regional configuration for EU868). I had some problems in the beginning because it seems that the CubeMX does not generate the BSP driver files (I read this in another question in this forum). So I coppied the BSP folder into my drivers folder of the project and added the ".extSettings" with the modified path to this same drivers folder in the project. Now the project could be built and downloaded/debugged.Can anyone confirm if this was well done?Anyway, this seemed to make the trick, but the code does not still work. When I run it into my board the code stops working before ending the first try to join. See next image:The join failed message never appears and the code is stuck at here: It seems it is waiting for an inter

I'm evaluating the ST25SDK-1.5.0 for the development of an application on Android but understood ST25TB tags are not supported.Any recommandations on how to implement ST25TB support on a mobile application ? Any workaround on android?Thanks

I am quite new with embedded programming. I must implement CRC8 with HAL and have tried to implement the CRC8 in python at the other end. Have used the crc8 library but both results don’t match. Is there anybody who could give me a hand to implement it correctly?

hello everyone, I have a small mistake when I want to make something like the photo, it give me error what is the problem, If anyone help me, It is very good for me, thanks.

Hi I would like to know if I can still get the interrupt updates of a timer but disable the call to the callback HAL_TIM_PeriodElapsedCallback.

HI all,I tried change option bytes for STM32WB55 in code, and probably something went wrong when I did this. After programming MCU I found that my flash was probably be blocked:How can I unblock FLASH? I tried change security config options in STM32CubeProgrammer, used CLI, used DFU mode but It didn not help.

I'm planning to use 2052 bytes per packet (ATT-MTU-2052) and I want to know if it is possible. So. here is a question.What's the maximum ATT-MTU and minimum connection interval of WB55 with BLE 5.2?

Hello,We are using M95512-6RMP with STM32WL5CC, we powered EEROM with STM32WLE5CC Pin. According to M95512-6RMP datasheet its voltage range is 1.8V-5.5V.I have attached our schematic of EEPORM connection.Please help us in this case. We want to use EEPROM at minimum of 2.2V.Thank You

I am looking for a self-test library to be able to pass UL-60730 class-B certification. Request you to help me if such a library exists.Regards,Bhavya.

Hello, this will be a rather advanced problem that I'll be presenting so please bear with me until the end.I'm currently working on I2C communication, with a configuration where I have a controller that initialize 4 STM32g0 on custom PCBs.TL;DR : I want to combine data transmitted from target transmitters by broadcast, using the fact that I2C bus lines are driven low but it doesn't work.Context ----------------------------------------At initialization, the I2C controller (on SoC) will individually set each STM32g0 boards (targets) with a custom ID and two address : a broadcast address, and an individual address (which depends on the ID). This is done with the help of a mux and after this initialization, the mux is always set so that all STM32g0 are connected to the I2C bus.Presently, the controller sends a command to say it will request to read some specific data to each target (STM32g0) individually then reads the data after a repeated start condition.I2C communication presently looks

I have a project that inadvertently appears to have what looks like the bootloader area.I'm using STM32CubeIDE and when I program the board from the IDE, it runs fine and all is ok. If I press the reset button then the board ceases to run.I've duplicated the debug session to allow me to attach while the board is running. After the compiling and programming the board from the IDE. I can see it running as expected and attach the debug session without a problem. If I press the reset button then attach the debug session, I get the following message:Break at address "0x1ff09c94" with no debug information available, or outside of program code.I understand that the main reset part of this area is generally handled via a jump to 0x1ff09800.I'm using an STM32H750 on an in-house developed board. The reset button pulls NRST to ground. I've checked the option bytes against another board that has previously worked ok and they are the same. I've not programmed the other board as I don't want to unne

 I'm trying to download Starter Package to microSD card on STM32MP157F-DK2 via USB.I clicked "Open file", selected "FlashLayout_sdcard_stm32mp157f-dk2-trusted.csv", pressed RESET button, clicked "connect" and tried to download.​However, STM32CubeProgrammer showed the message "MMC erase failed", or "an error occured while uploading data from the virtual partition 0xF1".​Please tell me someone about what shall I do to remove these errors.​Note:・Both DIPSW (BOOT0 and BOOT2) are set to OFF. ​・I'm using Kingston 16GB microSDHC for downloading.・I want to use the Programmer for WIndows10 not for Linux if possible.​

Dear to All,I have a boar with STM32G030J6 and I want use the TIM3 as PWM output (on PB0->TIM3_CH3) using DMA1 channel 3 to transfer data from RAM memory to TIM3_CCR3 register.

I noticed this driver https://github.com/EmcraftSystems/linux-emcraft/blob/master/drivers/rtc/rtc-stm32f2.cIs it possible to configure the stm32g030c8 to be an i2c slave and provide it's RTC to an external system that runs linux and uses this driver? Or do I have to implement a full i2c slave that would emulate another discrete RTC?

Hello, I want to know if there are other platforms like proteus in which I can virtually simulate STM32 MCU and OLED display.STM32 programs are not working in proteus. I just used simple toggle LED program but it is not running on proteus,

Has anyone else seen this?I have never seen such a problem in years of debugging with EWARM and STM32's through sleep modes: using source and project files that debug fine with EWARM 9.20.2, now with 9.20.4, the IAR IDE is hung on the ST LINK driver as shown in the attached screen shot. IDE is unresponsive until I cause an EXTIO to wake the STM32WB from STOP2. I reported this first to IAR, but the engineer responding to me, Dave, keeps asking for logs, and as you can see from the screen shot, nothing interesting is getting logged. so the IAR support seems to be at an impasse.

Dear community, I am facing a weird problem on using the SPI after migrating my codes from STM32F407 to STM32F767.The SPI is configured as slave and interfaces with another STM32F406 MCU as master. The data received by the slave is sometimes shifted by one or two bytes. I am using the CMSIS middleware API. The same source code, when compile for another STM32F406 (which is my original target) runs without problem. I noticed that the Data Register of the SPI (SPIx_DR) is sometimes filled upto the 2nd byte even though Datasize (CR2 DR[0:3]) is set to 8-bit, and MSIZE and PSIZE in DMA are both 0 (BYTE). Comparing with the STM32F4 master the data register is consistently only using the lower 8 bitsI do not have the D_CACHE enabled so I have compiled the CMSIS driver with SPI_DCACHE=0. It has the CRC calculation enabled and it did not report any data corruption on both sides.The master is able to receive the data correctly.

Do the integrated circuits L9823, E-L9823, E-L982301 differ or are they identical?Are they still in production?

When I compile, I get the following error: The float formatting support (-u_printf_float)is not enabled from linker flagsI can't find Linker flags/Options/Settings for C - just for MCU G++ Linker. When I chose the option, it still didn't remove the error. It compiles, though and can be run.

I have been working with STM32H753 device. I was able to boot into the system booltoader of the Nucleo board. Cube Programmer was able to detect and connect through UART.But, I am unable to connect the Cube programmer in our custom board. Both BOOT_ADD0 and BOOT_ADD1 were set to 0x1FF0. After booting, I connected J-Link to verify that the PC is at 0x1FFx series addresses.Looking further, whenver I halt and run the CPU through J-Link, the PC seems to be at address 0x1FF0AAF0 and the CycleCnt is increasing.I am not sure what could be possibly wrong.

I get this message whenever I try generating code with the "Other Toolchains (GPDSC)" in STM32CubeMX:The support of the “Tool chain / IDE�? you have selected will be soon discontinued in further STM32CubeMX version.If you want to benefit from further STM32CubeMX evolutions for your project, we advise you to target STM32CubeIDE or other IDE.I'm currently using this option to generate code for my IDE. Is this option being taken away soon? If so, what will my options be other than only using STM32CubeIDE?

I am using the CubeMX to set up a STM32F413 to receive audio signal form the I2S unit 1 . But then I found that the CubeMX do not allow set up of NVIC for unit 1, 4,5 of the I2S. Only unit 2,3 which have full duplex function have NVIC setting. This means one has to do polling to check whether data is received. And then the DMA setting only allow TX, not RX mode.But nothing in the manual RM0430 mentioned that unit 1, 4,5 are different from the unit 2 & 3 in this way. My understanding from the manual is all I2S units can be configured to generate interrupt by TXE or RXNE and DMA is available for both TX and RX.I misunderstood the manual or there is a bug in the CubeMX such that I have to hand code unit 1 of the I2S?
