According to the data sheet, sec 3.13.3 says the VBAT voltage is measure by the ADC as VBAT/3, or one third Vbat.using : uint64_t volt = (uint64_t)(((uint64_t)3300U*adc_result)/(uint64_t)4095U);I get 2/3 VbatChanging to uint64_t volt = (uint64_t)(((uint64_t)4950U*adc_result)/(uint64_t)4095U);I logged the followingVin Measured0.500 684 (seems to be the lowest it goes)1.000 9971.500 14962.000 19992.500 24963.000 29923.500 3.492Then in RM0454, 14.3.6 VBat/3, and 14.10 Digital value is half the Vbat voltage. While Showing Vbat/3.But I clearly see Vbat *2/3 from the ADC. Data sheet error?Thanks

Hello,I have an issue with my LIS2DE12, when i'm starting up my board i'm doing the configuration of the device and then i need to put the boad from 1,8V to 3,3V to communicate with an other component. BUT when I come back to 1,8V the LIS2DE12 have take back his default configuration... (REG0 = 16 ; REG1 = 7 ; OTHER = 0) Do you have ever seen this ?I have been looking with an oscilloscope the power supply and it never fall under 1,8V and never go more than 3,3v. (1,71v to 3,6v in the doc so looks good)Thanks,Regards,Goulwen LE BOZEC.

Hello developers, I have three custom pcbs. The heart of all pcbs is the STM32L151CCT6 µC in LQFP48 Package. I connected all supply pins (VLCD, VDDA, VDD_x to 3.3V; VSS_x to ground). The BOOT0 pin is connect to gnd with an 20k pull-down resistor. The reset pin (NRST) is connect with an 100nF capacitor to GND and an 10k pull-up resistor to 3.3V.I also checked all connections, especially the power supply pin connections. And I checked the supply voltage with an oscilloscope. All seems fine!After connecting the ST-Link debugger to the PCB the microcontroller works fine. Also after progromming it and running the program several times. But after around 10 minutes the Reset Pin starts to float at around 1.0V whearas it is connected in pull-up configuration to VDD as descriped before. This happens not on one board, it happens on all 3 pcbs!!!) In this state the µC cannot be reprogrammed anymore and the program doesn't run anymore, because the µC resets itself. Why the hell does it do that???

Good afternoon,I am a newbie in the programing of stm32. Just working on a project, where is a serious problem with timing. Trying to implement FOC on the PMSM motor where I need to do a calculation in 50us loop, which is fast to communicate with angle sensor via SPI and HAL. Let me explain the situation.I tried to work with HAL, but as I read everywhere and explored by myself: if you need speed put it away. So my plan is to use CubeMX to configure all necessary registers and read data directly from the register DR. One small thing, that sensor communicates with a 16-bit frame.Code that I produced:__HAL_SPI_ENABLE(&hspi3);   HAL_GPIO_WritePin_Fast(GPIOD, GPIO_PIN_2, GPIO_PIN_RESET); //switch off the pin   hspi3.Instance->DR = 0; while ((hspi3.Instance->SR & SPI_FLAG_RXNE) == 0){} //Wait for Data Ready to Read RxByte[0] = hspi3.Instance->DR; //Read Data Register Directly   HAL_GPIO_WritePin_Fast(GPIOD, GPIO_PIN_2, GPIO_PIN_SET); // switch on the pin

Hello,There are several issues when having project in STM32CubeIDE for STM32H747I-DISCO.1) When you open M4 or M7 main.c file, there doesn't work the autocomplete. But when you open this file by generating code from .IOC file, those files have autocomplete.As you can see in this gif, I have two times opened CM7 main.c. In one is auto-complete working, in one not.2) When debugging any core, I can step the code, but anytime I make breakpoint, and run the code, it breaks on some address, and not showing anything, so in conclusion, breakpoints even don't work.Thanks

Hi,I am trying to set Debug under Sys to "Synch Trace" in latest CubeMX but there is no such option for my STM32G474RE: On other screenshots on the internet I see those options: Any idea why?Is Synch Trace not available on the 64 pin package???Thanks,Anguel

Hello,I am trying to use a ble application on the dongle board included in the P-Nucleo-WB55 pack. Is it possible to use the st-link debugger found on the Nucleo68 board to program the dongle? (This is the other board found in the P-Nucleo pack) the other alternative would be buying an external st-link programmer, something I’d like to avoid. I tried connecting the nrst, gnd, swdio, and swclk pins from cn13 on the Nucleo68 to the dongle and powering both boards, but stm32cubeprogrammer did not recognize the stm32 device.

Hi,We've been using LIS3DSH for a few years now and are now searching for alternative sensor because of availability problems.In LIS3DSH there are offset compensation registers OFF_X(Y,Z) for fixing the read axle values with correction values stored in manufacturing phase (TyOff).However I can't see any such registers in LIS3DH documentation, although there are same chapters in document (3.1.2 Zero-g level and 3.5 Factory calibration).I haven't yet been able to test the sensor, but just for preparing to the sensor change, are the offsets detected on manufacturing phase of LIS3H taken care somehow automagically, or am I missing something here?Best regards,Jukka

Hi friends,Yesterday I flashed my STM32F205 (custom board) and since that point, the RESET pin is always low : and I can't connect the MCU to flash it or erase or any other actions.I'm not sure of what happened, but it was maybe because my makefile was set to "device STM32F205RBTX" instead of "device STM32F205RCTX" and it erased some SWD registers in the bootloader?The BOOT0 pin is connected to the ground (through a 10K resistor) and VCAP_1 and VCAP_2 are like the datasheet. My other custom boards are working well. There is no short circuit or design problems.Do you have a solution to fix that problem without need to change to STM32F205 chip ?Have a nice day :)Jean

Hello everybody!The documentation indicates that this leg can only be configured as an ADC input. In "CUBE MX" it can be defined as different kinds of interfaces. Who should I believe that my project would work properly and I would not be faced with the fact that this leg cannot be used as I need?

Hello,I'm trying to get multi-buffer DMA on ADC working. I modified `HAL_ADC_Start_DMA` function to use `HAL_DMAEx_MultiBufferStart_IT`instead of `HAL_DMA_Start_IT.But for some reason, M0 Completion Callback is executed multiple times before switching to M1 buffer.uint32_t bit = READ_BIT(((DMA_Stream_TypeDef *)hadc1.DMA_Handle->Instance)->CR, DMA_SxCR_CT); printf("BIT: %s\r\n", bit ? "1" : "0");I have this in IRQ handler (on M0 or M1 conversion complete callback), and for some reason, flow is following:BIT: 1BIT: 1BIT: 1BIT: 0BIT: 0BIT: 1BIT: 1BIT: 1BIT: 0BIT: 0BIT: 1BIT: 1BIT: 0As you can see, it doesn't switch CT like it should (M0 M1 M0 M1 M0 etc...) but the buffer is used multiple times before it's switched. Any ideas where can be an issue?Thanks.

Hi everyone, I've written this little python script to control the brightness in several LED1642GW drivers connected in daisy chain. According to their Application Note, at page 4, it says you have to send 16 words of 16 bits where the first 15 must have a "Brightness data latch" while the last one must have a "Brightness global latch". My question actually is what those 16 words mean? Does they mean the brightness level? According again to the Application Note... at page 10 the default value of CFG-15 is "0", which means that "16-bit brightness register (65536 grayscale brightness steps)" is selected. So ... I think I should see some brightness variation when I send some different value than 0xFFFF (65535).The point is that I see always the same brightness level regardless of the value I send. Nevertheless, I have to set the brightness because otherwise LEDs will not turn on when I send the write switch.What do you think? Am I misunderstanding the protocol to set up the brightness? Th

Rev. 5 of those RMs introduced dual-bank devices. According to "3.3.1 FLASH memory organization" the page numbers in bank 2 start at 256, which seems to be very odd as the PNB field in FLASH_CR has 10 bits, so one would expect 1024 instead.

I use STM32CubeIDE under MacOS. I don't understand whether it is a bug or not. I can not change Input frequency of HSE in clock configuration. I can do it in CubeMX under Window on the same project.

There is no file named DTM_UART.hex  in the installed folder of STSW-BLUENRG-DK.I reinstalled 2 times. please guide and there is no proper mention of the connections required in AEK-COM-BLEV1.pdf.

Hi,I've got the latest SPC5Studio 6 with all updates (gcc4.9.4) and testing on the SPC560D40L1 chip with the discovery board. So core is e200z0h VLE.I want to manipulate the flash in my app so I need to call some code from the RAM. I added the necessary sections in the application.ld, and the necessary attribute for my method :__attribute__ ((section (".codeinram"))) void method_in_ram()I'm calling this method from flash codevoid flash_method() { method_in_ram()}All this compile correctly (no warning, no error), but this crashes during debug with invalid opcode...I decompiled the hex, found that the flash_method content is not VLE code but PPC code !! e200z0h does not support PPC but only PPC VLE. Why is gcc creating PPC opcodes to call a method in RAM ? I tried to add longcall attribute but it does not help ...Any help appreciated!Thanks

Hi,In the sample application for SPC584BXXX flash test, the hex file is written on RAM and then executed. I need the hex file to get written on flash and then write some data on other specific sectors of flash. So I modified the linker script by changing the RAM sections by flash at some places but the program doesn't work as expected. Please help me to get an appropriate solution so that the hex gets written on flash and the FlashWrite Flashinit, FlashErase etc. will work as expected.Thanks in advance.

STM32CubeMX doesn't show MII as an option for Ethernet on the STM32H730VBTx. Is MII not available on this part (RMII only?) or is there a problem with STM32CubeMX? The datasheet suggests it should support MII.
