Solved

Hello,We are using ST25R3920 with another host MCU(NXP S32K116) in a project. Our customer want us to be able to update the firmwares of modules in the board via host MCU if a new feature or some problem fixes are needed.So my question is, does ST25R3920 support such feature? If yes, does ST provide the new firmware for the module?I looked through the documents related to ST253920 but could not find any information regarding this issue.Thank you and best regards,Furkan

I am trying to use ST3993 to get distance between tag and the reader.Is there any SDK or function in the ST3993 to do that?

we installed an application binary on NUCLEO-144/F429ZI with UART2 as an external interface and USB-UART for debugger.And the binary code been downloaded via the debugger port using STM32CubeProgramer with the tool option of "STM32CubeProgramer(SWD)" and "USB support(if possible): None"It goes well without readout protection of OB(Option Byte). Also well in serial out on USB-USART.By the way, once Read out protection was set to 'BB' from 'AA', it will not go well. no output on USB-UART.What's my misunderstanding on the Readout protection?

[Solution] Code was moved around and then it compiled correctly. Misinterpretation of the problem.IOC Configuration: Pin PB9 - External Interrupt with Rising/Falling Edge trigger detectionPull-DownNVIC EXTI line [9:5] Enabled Preemption Priority 1 Sub Priority 0Code Changes: Inside Main.c/* USER CODE BEGIN WHILE */void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { HAL_GPIO_WritePin(GPIOB, GPIO_PIN_11, GPIO_PIN_SET); }To my understanding to accomplish the interrupt with a callback to turn an led on all I need to do is change the state of the pin from high to low or visa versa. Then override the _weak definition of HAL_GPIO_EXTI_Callback.Any advice would be very helpful here but I have tried almost all of the different settings for registering the interrupts without any luck.

I think there is an error in the reference manual (RM0440 Rev 7) in chapter 24.5 - COMP interrupts.At the end of this chapter it says: "Interrupt events are flagged through COMP_CxCSR flags."But in COMP_CxCSR register there is no flag for interrupt event?The Interrupt is handled by EXTI, so the Flags are in the EXTI_PR1/EXTI_PR2 register.Or do I miss something?

I have ST25RU3993s with marking "E". I see a note in rev.11 datasheet mentioned not to used the "E" or "ES" marking for the production board. (1)Is the note still true? (2)If It's released in the field, what kind of failures do I expect?Thanks,-Tieng

Hi Guys,In STM32CubeIDE I start a new project for this board, I leave everything in the ioc unchanged and generate the code.The call to MX_USB_OTG_HS_HCD_Init() works correctly.I now change in the ioc: USB_OTG_HS Internal HS Phy from host_only to device_only and regenerate the code.Now the call to MX_USB_OTG_HS_PCD_Init() ends up in the Error_Handler(), this is caused by a timeout in USB_CoreReset().Does anyone have any ideas why this might be?Many thanksAndy

I'd like to play a FHD video 1920x1080 25 fps on a FHD monitor.There is some hardware codec inside MPU I can use?On other platform (like imx6 I used it own codec h264), but reading datasheet I don'r find anything about codecs video on thi MPU.I suppose MPU has not usable hardare video codec.Thanks all MZ

I made an I2C communication between STM32U585 uC to an I2C EEPROM and it worksI do the following  but if I remove the HAL_Delay(10) or minimizes it to less than 10msec things are not working well, the second call I2C_Master_Transmit fails.Is there's a way to call the I2C_ISR register or anything else, in order to check if the writing process was completed before proceeding with the communication?Thanks!

Hello,I'm currently prototyping a custom design utilizing the ST25RU3993 which should be nearly identical to the reference design HPEV. I've removed the external PA and 2nd antenna, but otherwise the design is very similar. I've attached the schematic for comparison. Where available, I've followed the reference layout as closely as possible.The board is showing poor read rates (low distance, ~50% success rate for consistent tag-antenna positions) which I suspect is the result of the following: the RX probe point (equivalently RF-TP4 on the eval kit) shows almost 5dBm at the carrier frequency when measured with the spectrum analyzer. I understand this should be closer to -14dBm.Am I missing something obvious from my design? Or could this be a possible result of an assembly issue? Looking forwards to any insight into the issue or further testing I can perform.Thanks!

MCU: STM32l47xxxHi,I am attempting to modify Option Bytes in code and am seeing undesirable behavior.The purpose for modifying the OBs is to be able to reset into Bank 2 afterward. I am implementing to perform a on-the-fly DFU similar to the method found in AN4767. I have looked at both AN 4657 and its example code and followed their method in order to modify the OBs.After running the code below, the MCU halts and becomes unresponsive. The only way to get it out of this state is to reset the OBs using JLinkSTM32.I have also looked at the datasheet for this MCU and followed their steps, I am not using HAL libraries so everything is through registers.Is there a missing step that I am not understanding that is preventing the MCU to reset into Bank 2? I have flashed my application at the start of Bank 2 to test if its working.Any help would be appreciated! -Tom// Function to program the options bytes void ProgramOptionsBytes(void) { SYS_UnlockFlashWrite();   while (FLASH->SR &amp

Dear community,I'm still facing an issue with my SD card slot on my STM32F410RB Nucleo Board while using the CUBE IDE. After resetting the microcontroller, I'm able to mount the SD card successfully again, but as soon as I remove the card, I'm not able to mount it anymore.When trying to mount the card after removing it, I'm getting an error message of FR_NOT_READY from the f_mount function. I've tried various things to fix the issue, such as testing the SD card in different slots and trying different pull-up and pull-down configurations, but unfortunately, nothing has worked so far.Since I'm using the CUBE IDE, I was wondering if anyone in the community has had a similar experience or has any tips on how to fix this problem within the IDE. Any help would be greatly appreciated.void process_SD_card( void ){ if (SdCardConnected == 1) { printf("SD Card found\r\n"); FATFS    FatFs;      //Fatfs handle  FIL    &nb

Hello, I'm using a STM32L476RG Nucleo board for a personnal project. While playing with the ADC, I noticed something strange: ADC raw readings seems to be off.My experiment, connect the middle pin of a 100k potentiometer to the PC0 pin, and record different ADC output code with different voltage.The code used for the experiment:The output codes are read using the debug tool in Cube IDE, pausing after reading. Multiples readings are done before selecting a value.Using excel, I came up with this chart:Blue line corresponds to the data recorded: ADC output code vs Applied voltage.Orange line corresponds to the output code I'm supposed to get using the theorical formula: Ouput code = Vin * 4095/3.3 (3.3 being the voltage on the AREF pin, 4095 beiing the max output code possible with a 12 bit ADC).By playing with the formula, I found out a reference voltage that could give me a theorical curve close to my practical one in the 3.7V-3.8V range: Blue line is the same as before, while oran

If server1 is connected to the client and when I try to connect with server2, will server1 still be connected?because once 2 servers are connected I am not able to GATT Write attribute to an individual server.I am able to write only newly connected server only.I am using "aci_gatt_write_without_resp" to write even if I change Connection_Handle parameter also I am not able to write to server1. Thank You.

Hi, I recently had to update the LSE Drive Capability from "low drive" (0x00) to "medium high drive" (0x02) for an STM32U575 project. After making this change in STM32CubeMx and programming the micro with the newly generated code, I noticed the updated LSE drive level was not being set, it was still using the previous value.Upon further debugging, I noticed the generated code is not disabling the LSE before updating the the drive level via `__HAL_RCC_LSEDRIVE_CONFIG()`. This appears to be a bug with the generated STM32CubeMx code.My fix has been to disable the LSE before the function `SystemClock_Config()` gets called, which will then perform the LSE drive level configuration, as a well as, enabling the LSE. However I want to check if this is the proper way to set the drive level or if anything else should be done.
