Solved

Hi to allI got interested on STM32WB55CGU6 which is recently available as a development board found online and in its reference manual I kind of notice that there is no detailed explanation or rather configuration for the Radio CTRL register and BLE Cntrl. Are these suppose to be like this? Any help with you guys. Best regards.

After I updated ST-Link to firmware version V2J43S7 through STM32 Cube Programmer, I can't connect it to my laptop and program my STM32 F405 Feather board. I have attached the error message to this post.

Why isn't VREFBUF enable available in CubeMX for the STM32L432 series? I believe the reference manual says this series has control over the VREFBUF. It also seems there's no struct for VREFBUF control in the stm32l432xx.h file.

Hellois it possible for the microcontroller with USB OTG to download the program memory from the USB stick itself?In other words, change the firmware simply by connecting a USB stick with a .bin file and perhaps by resetting the component.So far I have solved it using two MCUs. One only reads the .bin file from the USB and then uploads it to the target device via the usart bootloader, but this seems too impractical to me.

Hello, I m trying to establish a CANFD communication with an FPGA and an STM32 NUCLEO-H7A3ZI-Q. I just want the stm32 to transmit data to the FPGA. My colleague did the code for the STM32 and for standard CAN, everything works. I can receive the data and my CRC calculation is the same as the one that i had sent to me.    For the CANFD, the trame is all good until the CRC. He just sends me 1 byte data and the CRC that i can observe is to big for an FDCAN (supposed to be 17 and 21 for more than 16 bytes).  Here is the frame that he sent me: ID : 00000010001 RTR : 0 IDE : 0 CONTROL: 10000001 DATA : 01001000 All the frame : 00000010001001000000101001000 Here is an image of what i can observe : The frame that we can observe is (Start bit in black, stuff_bit :( 0000010010001001000001010100100010110111110111010100110001011111111111111111 If i remove bitstuffing, the begining is the same 00000010001001000000101001000 (frame)    10110111111110101001100010

Hi,I have a small problem with the RTC on STM32MP153. From hardware point of view I'm able to see sine waveform on the resonator 32.768kHz which is connected to PC14, PC15.I use the Openstlinux - kirkstone (openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23).I configure rtc section only in tfa file  clocks { /* USER CODE BEGIN clocks */ clk_lsi: clk-lsi { clock-frequency = <32000>; }; clk_hsi: clk-hsi { clock-frequency = <64000000>; }; clk_csi: clk-csi { clock-frequency = <4000000>; }; clk_hse: clk-hse { clock-frequency = <24000000>; }; /* USER CODE END clocks */ /* USER CODE BEGIN clk_lse */ clk_lse: clk-lse { st,drive = < LSEDRV_MEDIUM_HIGH >; #clock-cells = <0>; compatible = "fixed-clock"; clock-frequency = <32768>; }; /* USER CODE END clk_lse */ /* USER CODE BEGIN clk_hse */ /* USER CODE END clk_hse */ }; ... &rcc{ status = "okay"; /* USER CODE BEGIN rcc */ /* USER CODE E

Hello,I'm using a newly installed STM32CubeIDE on GNU/Linux (Debian/sid, from the .deb provided by ST), without any modification.I create a new STM32 project in an empty workspace. Project creation : Very slow, then unlockTo create this new project it takes 16 minutes. During this time, the UI is stuck in the dialog "Perform Project Creation. Please Wait For Completion ...", and one of the Eclipse processes has the CPU at 100%, and memory close to 2GB (I extended the default max to -Xmx2048m in stm32cubeide.ini), then after ~16 minutes, some things unlock, and the rest of the project creation is completed at expected speed. Build : Very slow, then unlockThen to build that empty project, it takes 4 minutes : Eclipse seems to hang just after calling make, but before make does anything (I added the --trace option to make to check its progress, and it has not yet reached its first step). Then, again, at once something unlocks, and the the build actually take place in the expected

Hello Community... We are working on a project for the automotive area and one of the requirements is that the circuit is powered by a voltage of 5V. We will also have analog inputs that should read values ​​between 0 and 5V. Reading the Reference Manual, we found the "CFlash Nonvolatile User Options register (NVUSRO)" which, according to our understanding, should have its PAD3V5V field written as 0, but we don't know exactly how to change/program the value of this register.On our board the VDD_HV and VDD_HV_ADCx voltages are supplied by 5 volts.All the board's peripherals (CAN/UART/Digital I/O, etc.) are working properly, however, when we put a voltage of 5 V on the pin used as ADC (PF[0],PD[13],PD[14] or PD[15]) it is crimped at a maximum value of 3.4V.Could anyone help us better understand the reason for this maximum voltage at the ADC input and also the procedure for writing to NVUSRO? Thanks in advance.

Hello ST expert,I'd like to control 4 300W motors with the BLDC L6234 and my STM32F401, but the problem is that I can't use 12 TIMERS and 12 GPIOs just for that, I need to interface other modules.Can I just use PWM/BLDC, and interface the two like that?   STM32F401 L6234PD | | | PA6 (PWM) ----------> | EN1 (3) | PA6 (PWM) ----------> | EN2 (6) | PA6 (PWM) ----------> | EN3 (11) | PB0 ----------------> | IN1 (17) | PB1 ----------------> | IN2 (18) | PB2 ----------------> | IN3 (19) | | | | | 11V ----------------| VS (10) | | GND ---------------| GND (1, 2, 7, 16) ----+ | | | | OUT1 (4, 5) -------> Phase U of Motor | | OUT2 (8, 9) -------> Phase V of Motor | | OUT3 (14, 15) -----> Phase W of Motor   Best regard.

Hello, I am writing FDCAN driver filtering function for the open source ChibiOS RTOS, both for FdCanV2(H7) and FdCanV1(G4) For the H7 side, all went easy, and the driver works as intended. On the G4 side,  FdCanV1 is a bit simpler (the ram buffer is not shared between interfaces, and  sections size are fixed) so it should be even easier, but that's not the case and I am unable to filter. What I do to enable filtering is : ° enable configuration change :  setting FDCAN_CCCR_CCE | FDCAN_CCCR_INIT in CCCR register ° setting fields in RXGFC register : reject non filtered frame, and setting number of filters ° setting filters in the ram buffer at the SRAMCAN_FLESA position, in my case for FDCAN1 interface, it is 0x4000a5c0 for extended filters ° removing FDCAN_CCCR_INIT in CCCR register ° using debugger, I tested that RXGFC has the expected value, and that ram buffer contains the expected filters ° XIDAM global mask is left at init value (no global masking done) Without

I2C_TIMINGR is configured for I2C bus speed of 400kHz. Is his configuration correct?   PRESC[3:0] = 0010 (PRESC = 2) SCLDEL[3:0] = 0001 (SCLDEL = 1) SDADEL[3:0] = 0001 (SDADEL = 1) SCLL[7:0] = 00001010 (SCLL = 10) SCLH[7:0] = 00001010 (SCLH = 10) Is it correct or not?

Hi Team,I am Using NUCLEO-F439ZI EVM, while using ethernet interfacing,In the RMII mode: LWIP -> Platform Setting -> Driver_PHY - both LAN8742 and DP83848 are enable.In the MII mode (both half-duplex and full duplex):LWIP -> Platform Setting -> Driver_PHY - only DP83848 are enable.My problem was, while using TCP client and server programming, I choose MII mode, I does not show LAN8742. while using RMII mode, the sent from PC -> EVM board, it cannot accept the data. Guide, what is the mistake done? give the clarification.Thank YouRamachandran.S 

There's a problem enabling QuadSPI in CubeIDE. After enabling QSPI and generating the code, compile errors occur.Here are the issues I've identified:XSPI_HandleTypeDef is not defined.There's no define related to QSPI (or XSPI) Enable in the stm32mp13xx_hal_conf.h file.Declarations for HAL_XSPI_MspInit and HAL_XSPI_MspDeInit functions' code are missing in the stm32mp13xx_hal_msp.c file.HAL_XSPI_MODULE_ENABLED is not present in stm32mp13xx_hal_conf.h. Thank you for your help.

Hello everyone, sorry if this is too easy of a task but I am quite frustrated. Can anyone help? I want to use CP2102 USB to UART bridge to send data from my PC to my Nucleo, then send the exact same data from my Nucleo to the PC so I know that the data has been received successfully. I have connected the Tx of CP2102 to the Rx of UART2 and Rx of CP2102 to the Tx of UART2, then connected the grounds and VCCs of the chip and board together (I am using 3.3V for this project. The baudrate I am currently using is 115200 but I have used 9600 with no changes to the result. I have also changed the UART ports I have used, to no avail: Did both receiver and transmitter on UART1, the receiver on UART1 with the transmitter on UART2, the receiver on UART2 with the transmitter on UART1... I thought maybe my CP2102 was faulty but when I short TX and RX I do get the echo of my typing back so that was not it either.The CP2102's transmitter's LED is blinking when I type, which is a good sign, but the re

I recently purchased a STM32F769NI MCU Discovery Kit. The kit is brand new, and I was looking to run the example display application "LCD_PicturesFromSDCard" from the most recent version of STM32CubeF7 software package. I downloaded the most recent version of STM32CubeF7 (1.17.0) as well as the most recent patch (1.17.1). I compiled the "LCD_PicturesFromSDCard" project in Keil uVision5 changing the optimization level to 0 and changed the defined processor symbol from "USE_STM32F769I_DISCO" to "USE_STM32F769I_DISCO_REVB03". As instructed via the readme.txt for this specific example application, I created a "Media" directory under the empty micro SD card root, and copied the 5 .bmp images provided in the sample application to the micro SD. I then connected the micro SD to the STM32F769NI MCU Discovery Kit and tried to run the application to display the photos with no success. The error of no bitmap files is consistently debug outputted to the display. I repeated the p

Hello, I am using the STSAFE-A110 connected to the ESP32C3 board. I referred to the service interface from this GitHub repository (https://github.com/kmwebnet/stsafe_esp32_test). I have matched the Host MAC key and cipher key exactly as in the example. The current status is that pairing is complete, and the wrap operation returns a success response. However, I am encountering a 0x11 error during the unwrap operation.     Unwrap_Failed : 17 <- print decimal data       

Hello everyone,I am using an STM32L152RE board to generate a delay using the RTC as a timer. I would like the onboard LED to blink every 10 seconds. I have tried using a delay via a timer and am now trying to implement the same functionality using the internal RTC.I have configured all the ports and selected the appropriate clock, i.e., LSE. Below, I have attached the main file. Although the RTC is running, there is no change in the LED. Can you please help me with this issue?Thank you,

Hi,I have a problem with my project. There are two boards MCU1 and MCU2. They are communicating with each other via UART. I simplified program to better understand why it is still not working but somehow I still cant see what the problem. Program description:1. MCU1 send to MCU2 AA (AA is array filled with two 0xAA)2. MCU2 send to MCU1 CC (CC is array filled with two 0xCC)3. MCU1 after receiveing 0xCC starts engine4.MCU1 send to MCU2 BB (BB is array filled with two 0xBB)5. MCU2 send to MCU1 DD (DD is array filled with two 0xDD)6. MCU1 after receiving 0xDD starts hornOn 6 step there is a problem. I can see on oscilloscope that DD frame is coming to MCU1 but somehow MCU1 doesnt go to callback function and doesnt exceute code in callback function - doesnt turn on the horn, rest of the code is executing fine.Baud rate is the same for both MCUs. Source code MCU1:/* USER CODE BEGIN 0 */ uint8_t buffer[2]; uint8_t AA[2]={0xAA,0xAA}; uint8_t BB[2]={0xBB,0xBB}; void HAL_UART_RxCpl

As stated in UM1052, chapter 14 there is often a requirement to control a BLDC motor control board over a serial connection. The above manual describes the protocol used by older MCSDKs. But the latest MCSDK 5.Y.x seems to use a slightly different procol called ASPEP.Unfortunately I could not find a documentation for that protocol on the ST web site.My question is: Is there any documentation of that new protocol or is it required to reverse engineer the STM source code to use it with an different application than the Motor Pilot?Thank you for any hints!Best Regards Thomas
