Hi,I am currently working on a bluetooth application, on an STM32WB55 microcontroller, to which I have integrated OTA update functionality.As Loader I used the one present in the provided code examples.The application and downloads work properly, my question is: what happens if the binary file I transmit is corrupted?At the moment I have run some tests. However, if I manipulate the binary file by going to delete parts or overwriting others, the trend may change. There are cases where after downloading it remains in the OTA loader and others where the firmware is loaded but the application crashes not allowing the binary to be reloaded.So in the loader present in the examples I think that in addition to the key check there is no check on the validity of the received binary, is there?In that sense how could one proceed? By inserting an additional check in the loader (e.g., CRC) or has some other functionality been provided?Thank you very much

Hello,Is there a way to create a STM32cube IDE project using command line?Thanks,Mohammed

use the X-NUCLEO-NFC06A1 DEMO test p2p can't read slave listen , one board poll p2p and other board listen p2p

Hi everyone, I want to organise a little bit more our stm32cube projects. I want to remove Src and Inc folders and create some subfolders. Is it doable without having to use your own Makefile to compile the project ?Thanks in advance for your answer, and sorry if that question has already been answered.Best Regards,Thomas

How do I calculate the SPI CRC-16 in C? I have an STM32F429 sending me SPI data. These are the SPI settings:How do I implement a CRC-16 check implemented in C (not using STM32)?It is 16-bit data with LSB first. Polynomial X1+X3

I have to projects based on FreeRTOS. One is st example and one is generated by me from example .ioc file. All of the files in projects are the same (including FreeRTOS middleware directory). In the projects there is a task called periodically which set flag for the other task using osThreadFlagsSet function. While debugging I've noticed that osThreadFlagsSet function returnes different values. In one project rflags variable has value equal to 1: In the other rflags has some random value:and because of that I think that there might be the problem with setting flag for the task. Not setting the flag causes project work unstable. What might be the issue?

I'm using STM32WL V1.2.0 and trying to generate LoRaWAN End Node FreeRTOS application from .ioc file and make it work but I met some issues with sending data packets periodacally. After succescul join procedure device sends only one data packet. After Tx LmHandlerSend status is LORAMAC_HANDLER_BUSY_ERROR, MacCtx.MacState equals LORAMAC_TX_RUNNING and no more data packets are send. I think that the issue is caused by some part of FreeRTOS because I generated appliaction without it and everything works as expected but I can not find soucre of the problem. Here are steps that I made in order to generate application:- generated project using .ioc Configuration File from LoRaWAN_EndNode_FreeRTOS example- imported BSP driver and added it to include path- replaced generated app_freertos.c file with app_freertos.c file from LoRaWAN_EndNode_FreeRTOS example- inside lora_app.c file filled user code section of SendTxData function with own sending code:static void SendTxData(void) { /* USER CODE

I want to perform a timer interrupt using the output comparison mode.When the frequency is set to 2000Hz, ARR : 20, CCR1 : 25, I think that interrupt does not occur because ARR <CCR1, but interrupt occurs. Why do interrupts occur?

I have a STM32L431CCT6 uC configured with CubeMX (project attached): RTC connected to LSE 32.768 kHz, auto wake up enabled. In my code, I perform the following calls:HAL_GPIO_WritePin(LED2_RESET_ESP32_GPIO_Port, LED2_RESET_ESP32_Pin, GPIO_PinState::GPIO_PIN_RESET); HAL_PWREx_EnableInternalWakeUpLine(); result = HAL_RTCEx_SetWakeUpTimer(&hrtc, 0x0000FFFF, RTC_WAKEUPCLOCK_RTCCLK_DIV2); if(result == HAL_OK) { HAL_PWR_EnterSTANDBYMode(); }The uC enters correctly the standby mode, it should wake up after 4 seconds, ma it never does. I tried to check if wake up interrupt is launched, removing the HAL_PWR_EnterSTANDBYMode() call, but handler code is never executed (no breakpoint hit, no led blinked).

At the datasheet at figure 7 you use CMC befor connecting it to DC2DC.I connect the PM8805 to DC2DC LTM8027.If I don't put the CMC will it be worng?BRShmuel

Hi,I am working on a functionFS usb gadget based on gmidi. Following the gadget_configfs.rst and using stm32_usbotg_eth_config.sh as starting point was straight forward. After writing the shell script and modifying my device tree configuration to support high-speed OTG in the usb-c port as explained in the USB device tree guide, the usb gadget loaded with no errors and it was recognised by Mac, Windows and Linux hosts as usb-midi. USB-MIDI Shell script:configfs="/sys/kernel/config/usb_gadget" g=g1 #Gadget name c=c.1 #Configuration name d="${configfs}/${g}" #gadget path func_midi=midi.usb0 #Midi Function declaration #Product and Vendor for getting recognised VENDOR_ID="0x1d6b" PRODUCT_ID="0x0104" #Take the serial from the MP1 and make it a serial for our USB MIDI get_mac_address_from_serial_number(){ sha1sum /proc/device-tree/serial-number \ | fold -1 \ | sed -n '1{h;d};2{y/1235679abdef/000444888ccc/;H;d};13{g;s/\n//g;p;q};s/^/:/;N;H;d' } #To call the gadget do_start() { #Call depen

I have downloaded and implemented VL53L4CX driver following the example code. First I opened the provided example with CubeIDE (v1.8.0) and it failed to build. Looks like a fragment of refactoring. Also a source file was missing a struct definition, so I added an include. I don't know if this is where it should be, but it passes the build and the project works (on f411RE nucleo with provided shield).You can find the issue in my repository on github(i can't post link): "prtzl/vl53l4cx-demo", the fix was applied in commit: a40dfe72b40925ff08c20e87ce3c31ecaa8062c4Regards,Matej

Hello everyone,Is there a setting/command to limit the slew rate of I2C signals of a STM32F429ZI-Disco board? I know this feature is available on some Microchip micro-controllers.Thank you.

Hello,I wanted to ask if it would be possible to have the sequence of commands sent and how they should be formatted, by the STM32CubeMonitorRF tool to the board, so possibly I can recreate those steps even with a custom program.Thank you very much

uint8_t sdadc_lld_read(SDADCDriver *sdadcp, float* converted_value) {   int16_t data; uint8_t return_value = SDADC_DATA_NOTVALID;   /* check if valid data is available */ if (sdadcp->sdadc->SFR.B.DFEF == 0U) /* <- Check if the FIFO is not empty */ /* if (sdadcp->sdadc->SFR.B.CDVF == 1U) */ /* <- Check if data is valid */ { /* read converted data */ data = (int16_t)((uint16_t)sdadcp->sdadc->CDR.R);Is it right to check the DFEF (which is related with the FIFO) and not the CDVF (valid data)?

I am using SPC58EC disp board. I can upload code and see led is linking when I reset the board. But I can not debug it, my code’s start location is 0x01020000 but it is going somewhere else. I asked if I can set debug start location to PLS and they suggested me to ask to ST also they said use Hardware Start Mode but I couldnt find anything like that in software. How can I solve this problem? Thank you.

Hi Team,We are using ST10R167 in our design, as you that it is obsolete right now. So we have chosen an Alternate MCU, Part Number:SPC560P50L5CEFAR.Please let me know the Year to End of Life of the selected MCU and your comments on this Alternate.Looking forward to your support.Thanks & RegardsGangadhar

Hello,I'm searching the low level command to create multiples ndef files in a st25ta 2k tag. I know that there is a field in the system file that specifies the number of ndef files, but it is read only, so it isn't possible to specify the number of ndef files with an update binary command.I know it is possible to create multiple ndef files because on the software st25pc-nfc, there is a field where we can specify the number of ndef files we want, but it is high level and i don't know how it works.It is not possible either to update the CC to add the TLV of a new ndef file because it is read only too.I've searched on the tag datasheet, there is a topic, the 7.8 called : create and update an ndef file, but it doesn't explain at all how to create an ndef file.Best regards.

Hello,anybody can explain to me the difference between the BlueNRG-2 SoC and the BlueNRG-2N co-processor?Thank you,Sincerely ​

I know controllers push data to stack, PC to LR, etc. but how does this happens? Is it through software or hardware?If through software then where is the code which does this? and where does it come from? is it the compiler which adds it?If it is through hardware then how does it happen?

helloi need library for AT88RF04C and stm32f107thanks

I cannot disable SPI global interrupt in SPI Settings--> NVIC sub settings when DMA is used for SPI. When DMA is activate, SPI global interrupt check box became deactive. I am not sure if it is a problem or not. I suspect from everything because I have faced many problems in V6.5.0. I have an old project for STM32F745 and SPI global interrupt can be disabled in NVIC settings. Therefore I suspect about it. you can check my sample ioc file. Regards

Hi everyone,I am working on a FD-CAN project and i am able to send a 64 byte data frame. But I want to send multiple frames of data with different IDs. Any help would be greatly appreciated!

I've just started to learn FreeRTOS on CMSIS and im trying to make an interactive menu on a task and I also have another task with an HAL_GPIO_TogglePin just to coexist and see that both tasks are working. The menu text itself is sent to the terminal with no issues, then I send a character thar corresponds to one of the options available. The character is identified correctly and I've setted an informative message to confirm the option and give more instructions, but only the 2 or 3 first characters of the message are sent, then HardFault_Handler is activated.I've tried some solutions like changing the TIM6 to Systick for the Timebase Source, because some people say that Youtube Tutorials are wrong about changing it to TIM6.On the image below you can see my Transmit_Callback that I've been using in all my programs before starting to use FreeRtos.These are the functions that I call on the tasks to send the messagesThis is the Menu task:This is the new_Message function and the option fun

Hi, I want to report a problem in TouchGFX Designer, when a project has some widgets and containers in the custom containers tab and it needs to scroll down in the left bar, when I scroll down to the end of the list by mouse scroll wheel, the designer doesn't response to anything anymore and has to be terminated by the task manager.
