I have been using HAL_SPI_DMAStop to abort my SPI transactions and usually it works, but every once in a while I notice my SPI bus gets all jammed up or whatever and stops working. I noticed that the HAL_SPI_DMAStop function is not returning HAL_OK.Should I be using a different approach when using DMA? Also, How would I do this same thing if using IT (interrupts) instead of DMA? I tried using HAL_SPI_Abort_IT without any luck.To add a bit more context, I need to be able to use the SPI receive command to always be listening to another device and this device is a slave to it. As data becomes available to transmit back to the master, I need to abort the receive transaction and start a TransmitReceive transaction. Also note that this is being performed within a callback function (ISR) because my timing requirements are extremely tight.Thanks!

I am having STEVAL-IDB011V1 board. I am developing the battery profile for that i have refer the ADC_Battery_sensor and BLE_sensorDemo example but the code is stuck in below loop. Please let me know what is the issue in firmware. Is the issue is in ADC initialization. Please find the attached firmware link./** * @brief Disable the inversion of the ADC data output bits (1's complement) *     when a differential input is connected to the ADC * @rmtoll CONF   BIT_INVERT_DIFF   LL_ADC_InvertOutputBitDiffModeDisable * @param ADCx ADC instance * @retval None */__STATIC_INLINE void LL_ADC_InvertOutputBitDiffModeDisable(ADC_TypeDef *ADCx){ CLEAR_BIT(ADCx->CONF, ADC_CONF_BIT_INVERT_DIFF);}@Sebastien DENOUAL​ @Salvo​ @Salvatore DI SALVO​ @BlueNRG-LP Hands-On: Expanding Bluetooth​ @Sebastien DENOUAL​ https://drive.google.com/file/d/1Ijkz83Vn9KHylf9Kwu9mUnPLL7aWp-jZ/view?

HelloI'm starting to implement AES-GCM on STM32H753 (rev V).I've found an inconsistency between the HAL and the Ref Manual.The STMicro HAL for AES for STM32H7x3 is setting some bits called NPBLB in CRYP_CR register if the product revision is above rev B.But these bits are not documented in the ref manual rev 7.Is it just an error of the HAL ?

I have requested a X-CUBE-CRYPTOLIB V4 download last week, and no answer from ST.I have indicated all requested information and received an acknowledge, but no link to download the library.Could you tell me why ?

I received today the link to download version 2.6.0 of X-CUBE-SBSFU. Is it possible to install it along with the other X-CUBE Packages within the STM32CubeIDE? I successfully verified the integrity of the downloaded file and tried to install it using the "From Local..." button in the "Embedded Software Packages Manager" window.After the decompression of the file, the following error message is produced.  How should I proceed to install this expansion package?Nicola

this is my codeuint32_t delayCnt;int main(){ ledInit(); SysTick_Config(SystemCoreClock/48000); while(1) { GPIO_WriteBit(GPIOC, GPIO_Pin_13, Bit_SET); delay_ms(10000); GPIO_WriteBit(GPIOC, GPIO_Pin_13, Bit_RESET); }}

I want to measure analogue input ( 0-10V DC , 4-20ma) using STM32 MCU.​STM32 pin ip voltage (0-3.3)Now I want to convert 0-10V & 4-20ma in to (0-3.3V DC) what is the circuit diagram for getting 0-3.3V output ?​

I have multiple channels that I am trying to read from. I want to try both DMA and Interrupt mode.Does the callback follow the EOC flag, and therefore follow the 'End of Conversion Selection' setting in Cube (to which I have set to 'at the end of single channel conversion')? If so, does that mean when I call HAL_ADC_GetValue (say from this callback), I will be getting the result of the channel that has just been converted?For DMA I understand that HAL_ADC_ConvHalfCpltCallback is called when the chosen buffer I have given it is half full. So does that mean HAL_ADC_ConvCpltCallback is called when the buffer is completely full and not when a singular channel or all channels has been converted?

Why do some documents use Cube-MX instead of the MX inside of Cube-IDE? I can open an IOC with Cube-IDE and do everything Cube-MX does and more so why are so many examples using just Cube-MX? I downloaded the current version of Cube-MX but it is very slow, like watching paint dry compared to Cube-IDE

I am using STM32CubeExpansion_SBSFU_V2.6.0 to test SBSFU on B-L4S5I-IOT01A board.I am using the projects in the Projects/B-L4S5I-IOT01A/2_Images_KMS folder with STM32CubeIDE. I did not change or modify anything regarding the files.I first built the SECoreBin and then the SBSFU project. Then I followed UM2262 documentation page 48 to flash the SBSFU.bin image. I connected to the board with Tera Term but getting the following error output:Am I missing something?

I'm not sure if the failure is in tx or rx.The full generated project is attachedtested on dual nucleo-f401RE+S2868A1 boardstest protocol: reset both boards, click few times on blue button of a board, and see it just blink twice on the other board.I have no clue where to find the problem, I just see the example is failing fast, and when pushing a button the app think it does send radio frame.(it goes to: SM_STATE_SEND_DATA, SM_STATE_WAIT_FOR_TX_DONE and back to SM_STATE_START_RX )stm32cubeide 1.8.0SUB2G lib+example: 4.2.0

Hi everyone, I need to power my F401RE with a 3.3V external power source. I read in the datasheet I need to connect the power source to the CN7 pin 12 or CN7 pin 16. Where do I connect GND signal apart from 3.3V signal?Also, from what I understood, I need to desolder SB2 AND SB12 to get it working, to mantain the ST-LINK functionalities.​Am I correct? Do I need to remove/change any jumper positions? I don't seem to find info about jumpers for 3.3V.​Thank​ you​

Let's assume we have a software that uses FDCAN Classic and I2C with multiple slaves. FDCAN Priority = 1I2C Priority = 2During the transmission / Receiving process, the I2C is locked : __HAL_LOCK(hi2c);If an FDCAN interruption arrives during the I2C process, does the I2C get interrupted or does it wait until the I2C process get unlocked ?

On the STM32L051x6 datasheet it is written "PB9/12/13/14/15, PH0/1 and PC13 GPIOs should be configured as output and driven Low, even if they are not available onthis package" but in the "notes" space of the pin register descrpition there is no reference to this note. Anyway, since the packages are small i need to use to use those pins as I/O.What are the risks, if i use them as standard I/O? What exactly means "Should be" in a techincal datasheet without a clear description of the conseguencies? Thank you,Alex

I have a STM32WB35CEU7A. Vref doesn't provide a pin out, it's tied to Vdda internally. On my PCB Vdda is connected to Vdd. The question is: The ADC will take into account the internal Vref or Vdda ? I suppose the latter please verify. If that is the case can the internal Vref (Vrefbuf) still be read to offset the error from Vdda ?Thanks in advance

Currently we are using STM32G473CC controller for one our project, where we using CAN module(CAN 2.0 mode) in operation along with peripheral like UART1/LPUART1 in operation.We integrated CAN open stack on top of CAN driver for communication and in other side we use UART1 in operation. We are facing a problem that the CAN transmit error occurs when the UART1/LPUART1 is running in parallel to the CAN transmission. This in result the transmit error counter in FDCAN_ECR register increments and end up BUSOFF bit set. If the UART1/LPUART1 is not in operation the CAN operation is stable.Is there any limitation in the Controller core using CAN transmission and UART1/LPUART1 in parallel?What are the scenario the transmit error can occur in the transmit frame?

For example I have the following frame buffer data with mostly 0's and only the first value populated with a blue color.static const uint32_t image_data[480] = { 0x000000ff, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, . . 0x000000, 0x000000, 0x000000, 0x000000, 0x000000, 0x000000, . . 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, }With LTDC PixelFormat set to LTDC_PIXEL_FORMAT_RGB888 - I get the following output on the LCD. A single blue line on the left-most side of the LCD. I think I can reason about the output but this still raises a question. I was expecting the first value from the frame buffer data to represent a single point on the screen not an entire line. How would I represent a single point if not like this? I can reason about the color of the line since the value is 0x000000ff and the 2 least significant bits represent blue. The following 2 bits represent green, The ne

I've configured IWDG for my application (STM32L053). When I've halted the application during debugging, the IWDG is still triggering resets. I'm using a SEGGER j-link. I've attempted to use the __HAL_DBGMCU_FREEZE_IWDG() macro, but it doesn't seem to have any affect. I've also tried to write to the register directly:*((volatile int *)(0xE0042008)) |= (1 << 12);When I check in the SFR view for APB1_FZ, the DBG_IWDG_STOP value never changes.I can disable initializing the IWDG when debugging, but that isn't ideal. Any help?
