I create sample code for FLASH Erase Program on both mdk arm and stm32cubeide. Using the sample hardware(stm32h563ZITx develop board), the sample code runs correctly on stm32cubeide, but will enter Error hander when doing Flash operation in keil debug mode.:if (HAL_FLASHEx_Erase(&EraseInitStruct, &SectorError) != HAL_OK){while (1){Error_Handler();}} The C code for two project are the same. The only difference is IDE. This issue only occurs in debug mode. If I download the code into flash without entering debug mode, the code will successfully run. By debugging, I find FLASH_NS->NSSR was set as 0x0040000 when I get into the main function of debug mode in Keil, while FLASH_NS->NSSR is 0 when I debug on stm32cubeIDE. Then I try to manually clear FLASH_NS->NSSR by setting FLASH->NSCCR as 0x40000.But there will be following bug.

Hello,I want to read and write to st25dv64kc IC with X-Nucleo-NFC03A1 reader/writer. I can write up to 4 bytes with rfalNfcvPollerWriteSingleBlock() function. But when I want to write 2 blocks or more with rfalNfcvPollerWriteMultipleBlocks() function, I get an error when I want to read at the same time.What am I doing wrong in the code I wrote, How many blocks of multiple reads and multiple writes can I do at one time? void masterNFCV(rfalNfcvListenDevice *nfcvDev){      ReturnCode  err;      uint16_t rcvLen;      uint8_t blockNum = 2;      uint8_t rxBuf[1 + 2*4 + RFAL_CRC_LEN];      uint8_t *uid;      uint8_t reqFlag;       uint8_t wrData[8] = {0x11, 0x99, 0xFF, 0x00, 0x67, 0xA5, 0xCF, 0xFF};            uid = nfcvDev->InvRes.UID; &

I have a Nucleo F303ZE and enabled USB Device middleware along with the USB 'Device FS' Connectivity.  I also configured the CDC_SET_LINE_CODING and CDC_GET_LINE_CODING  functions in USB_DEVICE/App/usbd_cdc_if.c I connect a USB cable to the STLink connector as usual which powers the board.  I then connect a USB cable to the CN13 usb port but the PC does not 'detect' this new USB connection.  I run 'lsusb' on my linux machine and only see the STLink connection, but not the second USB connection.Any ideas on what I may have missed?Thanks

Hello,I'm using TCPP03 for a DRP solution. For my design it would be good to use the Mosfet drivers for controlling a logic input for further power control instead of using Mosfets. Is it possible to use the gatedrivers with the SRC-pins connected to Ground and feed the GATE-Pins to an input of a logic device? I'm aware that I have to take care for the logic level translation.I did already tests and it worked so far. Just to get safe that there will be nor furhter impacts, I want to know your suggestion for this.RegardsMichael Houzer   

Hello All,in the function VL53L0X_PerformSingleHistogramMeasurement from api library it is said that the code isn't implemented yet. Is there a way to get histogram measurements using this chip ? otherwise which chip should I choose to get histogram data ? Thank you

Can any of the expert share an example of ADC configured in Sequencer not fully configurable mode please?Its hard to find the solution .As the project had predefined prototype I need to sort it out with the configuaration and mandatory to use PA12 (adc_in_15)and PA11(adc_in15).Please

Using MP135F-DK board.Setup the environment and rebuild kernel.After I use openocd and gdb success connect to linux system, try to debug linux kernel, then run some simple gdb command like "bt" or do nothing, then system get reset.I did not get much useful info from console (minicom).if I don't pause system and let gdb "continue", then no reset.Is it because watchdog ? how to disable it.

Hi, I'm trying to develop a FW for one of my custom boards that has an ethernet interface.I'm using STM32CubeIDE, I generated the code with the configurator, and without even writing a line of code, if I go into debug, during the initialization of the HAL the code immediately jumps to: void Error_Handler(void){ I wanted to ask, Is there a way to know at which point the code jumped to Error_Handler(void), so as to try to understand where the problem is.In other words, is it possible to run the code backwards or see from which line a certain function was called?

Hello,I'm interfacing the STEVAL$MKI238AA through serial commands with STEVAL-MKI109V3. The UM2116 document in its Rev 10 - April 2022 doesn't mention any reference to the LIS2DUX12. I would like to know what is the format when I send the command *start. In table 4 (page 18) there is a long table explaining the format from all different board that can be connected but lacks of the STEVAL-MKI109V3.Could you guys provide an upgraded version of the document with this information or just the format that I'm looking for?Regards,Pascal.

Hi,I am creating an application where firmware version will be verified before flashing in the MCU flash using custom bootloader.Would like to understand, do we have any feature in STM32CubeIDE to append a header/ some dedicated data at the end of binary image while generating the .bin file for firmware.If not, can you please suggest some method to append firmware version in binary image, which can then be verified by bootloader before flashing the image in application area.

Do you have the antenna size and design process reference of NFC07A1? I want to know how to match the circuit and what is the inductance of the antenna.

Hi, I am trying to program the TFT LCD screen that is on STM3240G-EVAL MCU through STM32CUBEIDE. I just want to be able to put text onto it, or even a simple "Hello World program", but i cant get anything to display or find any tutorials. I'm not sure if i need to set each pin to an output on the STM32CUBEIDE, or whether i just don't have the write code. Any advice or links to tutorials or code would be appreciated. Thanks!

Hi CommunityI could use some help regarding UART on the "Bluepill" board so I can get my night sleep back againI'm working on a small project where I'm creating some interrupt driven bit frames on 16 outputs. Each frame is 16mSec long and consists of a 4.3mS start bit followed by 16 data-bits.each with a fixed 310uS low period, a fixed 155uS high period and the last part of each bit it 155us and is low or high dependent on the set valueSo far so good, this part is working very stable and reliable Then I need to receive commands on the UART and use these commands to set the bits in the frames, but I have big problems receiving these commands via the UART.The problem is that sending eg. abc and then cr to the UART is given me aabbbccc\0 in the Command bufferAs a test, looping the received byte back directly in the interrupt handler is given me ee when I send a single e to the UART port. Same for all chars.....I get 2 chars backWhat am I missing or what am I doing wrong?My understand

Hello,I would like to know how can i perform the Device Firmware upgrade using ST25DV dynamic tag.I am using "en.STSW-ST25DV001SC-Source_v1.2.0" and tried out both demonstration examples ST25DVDemo ( firmware update using internal flash)I am able to perform firmware update using ST25DV demo example, but after reset it jumps to original firmware. So i would like to know how can i implement a firmware upgrade feature using "ST25DVDemo" example so that after reset it boots to the uploaded firmware instead of the old firmware.Thanks,Nikhil.

Hello Team,In my application using STM32G431KCU6 at 160MHz, I want to trigger ADC2 channel by TIM1 channel. I aim to read ADC value synchronously with 1.1kHz pwm signal. When I set up the CubeMX config, i can see that TIM1 trigger OutputCompareCallback function but i can not trigger ADC_ConvCpltCallback. Shared my ADC and TIM1 configuration below:Also I am confused about starting ADC on software because ADC is not continuous conversion mode. Should i start and stop ADC as below or any suggest? My finalize code as below: Thanks for your help. Best Regards,Basri. 

Hi,I designed a board with NFC Chip ST25DV64KC, which will be connected with a extra antenna, during the selecting of antenna products, one parameter confuses me very much: the self-Resonance Frequency, is it important? For example this product. Or all antennas with specifical frequency 13.56MHz will work with ST25DV64KC? Thanks in advanc.Danny

I am using two stm32H7A3ZI-Q board to transmit and receive data (which is a double). I am using HAL_UART_Tramsit and HAL_UART_Receive_IT to send and receive the data. When i connect Tx to Rx on the same board, it sends and receives data fine. The image below, is showing that both boards are working when Tx is connected to Rx on the same board. When connecting the Tx of board 1 to Rx of board 2 and Tx of board 2 to Rx of board 1 it stops working and it receives nan (Not a Number). The image below is showing this. I dont think it has anything to do with my calculations because when i send a integer is still happens. Thank you for your help.  This is how i am sending and receive data  

Using F401 ADC continuous conversion and DMA for multiple channels.I have pins A0-7, B1, PC0-5 running conversions. For consecutive pins in a group (A0-7) (C0-5), the final pin in use always has a different offset error to the rest. Note this actually means the final /used/ pin in the group, e.g. If all 8 pins in group A are used, pinA7 has a different offset error to the rest. If only the first three 3 are used pinA2 has a different offset error to the rest. If the first 4 pins are used pinA2 no longer has the additional offset error but this is passed on to pinA3.These results are conversions from all pins being used. The ADC inputs are grounded with pull down resistors in all cases. The different sets of values (0-4 vs18- 25) represent different input impedances from input circuits. The ADC is 12 bits so the offset errors aren't particularly problematic, the issue for me is what could be causing the last value to have a different offset error?I've measured the pins with my oscillosc

I am building a high voltage fence controller, it requires a IRF820 Mosfet 500V 4A  N-channel. Apparently they are not manufactured anymore, and I can not find one anywhere, when trying to find out a replacement I am hitting brick walls with most people not knowing.The only Mosfet that keeps coming up is IRF830 500V 4.5A, will this be suitable or will it cause issues? Thank you for reading

Hi,    I'm working on enabling ETH on STM32H563. I tried to create a FW to do basic ping/ICMP in order to test the interface along with the PHY/switch chip. I found whenever I start the DMA by calling HAL_ETH_Transmit, it always returns HAL_ERROR due to timeout. I checked the status register, ETH_DMADSR and found TPS0 is set to 0x6, which indicates descriptor is not available or buffer underrun. I checked the descriptor and buffer with GDB and found nothing suspicious. Is there anything I should check?  Thank you.

I followed the instructions posted here to enter the bootloader and successfully connect to the MCU via USB using STM32CubeProgrammer.  When I attempt to load code the following error occurs:  09:12:45 : USB speed   : Full Speed (12MBit/s)  09:12:45 : Manuf.

(STM32F103C8)My program continuously sends UART messages with regular blocking calls like this:   HAL_UART_Transmit(&huart1, buf, size, timeout);   The result on my logic analyzer normally looks like: I also handle interrupts coming from HAL_SPI_TxRxCpltCallback at 1kHz. When this coincides with a UART transmission, the result looks like this:The SPI interrupt causes a slight delay in UART transmission, but it never seems to corrupt the transmitted data by getting "in between" the bits of each byte and messing up the timing. I ran a test for many hours and everything was fine. Is this behavior something I can depend on to always be true? If so, I would imagine that to accomplish this the UART is disabling interrupts during the time it is transferring each byte? I have a bunch of other timer interrupt driven code that is quite time-sensitive, just trying to understand if the UART will affect that.
