Solved

I was able to program two Nucleo-WBA52CG using STM32CubeIDE and the on board ST-Link. I programmed them with the BLE_HeartRateThreadX example application. When I power them I can see the BLE_HeartRateThreadX BLE traffic on my phone. However, I can not reprogram them again using the same setup. I suspect the problem is simple but I really have no idea what is wrong. Any help is appreciated. I get the error below when I try to program them.   ------ Switching to STM32CubeProgrammer ----- [36m[01m     ------------------------------------------------------------------- [39;49m[36m[01m                       STM32CubeProgrammer v2.13.0                  [39;49m[36m[01m     ------------------------------------------------------------------- &n

No GPIOx registers are present in System Viewer for STM32G051 or STM32G061 microcontrollers during debug session. There are 12 different .sfr files for each different variant of STM32G0 microcontroller, but only the above two lack GPIO registers in System Viewer window. Why? What is the magic reason for it, is it just a mistake by ST vendor to not include them or is there another reason? I tested what would happened if I loaded a custom file i.e. STM32G050.sfr instead and I can clearly see the GPIO config and its state being toggled that way. So than the question really is - why is it not included in STM32G051.sfr??? I know that all GPIO registers are memory mapped, but that is not a convenient way to debug whatsoever. I would really appreciate if someone reached out regarding this issue.

For example, I wish to use ADC1 (14 bits max) of STM32U575 at 12 bits, single ended. The datasheet guarantees a minimum of 68 dB for the SINAD, does this figure get reduced from 14 bits to 12 bits? If so, by how much?Thanks,Joel

I have an STM32H7 on a custom board. We do not have VBAT connected to anything. We do have a battery always connected to VDD. When I reset the MCU using the NRST pin it seems like the backup domain (registers and RAM) are not maintained. Is this expected? If I connect my power source to both VDD and VBAT will that correct the problem?The manual does say " If no external battery is used in the application, it is recommended to connect VBAT externally to VDD through a 100 nF external ceramic capacitor.". I plan to do that, but I want to know if the problem I'm experiencing is due to this and will be solved.Thanks,Dan

I am using nucleo STM32WB55RG to build an BLE application. I am having a very weird issue.At first I create an BLE application using CubeMX.I used server profile with custom template enabled (You can refer to attached cubemx file .ioc)The application will start advertising after all setup and init.I used an android phone with nRF Connect installed on it to scan advertising node.When I build and debug bare project (project generated from cubeMX without any modification), android phone can successfully see the device (nucleo stm32wb board) advertising.---> HOWEVER, WHEN I UNPLUGED THE BOARD AND PLUG IT AGAIN (DISCONNECT FROM POWER SOURCE AND CONNECT AGAIN), THE BOARD SENDS ALL DEBUG INFO WITH SUCCESS VIA UART (DEBUG MODE IS ENABLED)BUT THE PHONE CAN NOT SCAN THE BOARD SUCCESSFULLY.--> Additional info: when I program the board with BLE_p2pServer example, the above issue did NOT occur@@Please help me with this problem!!!Thank you very much

Hi all,I am new to motor control, and I am currently working with the BLDC motor driver board STEVAL-SPIN3201 (based on the STSPIN32F0). I am trying to generate the corresponding PWM signals to drive a BLDC motor. Although the low side of the bridge is working, whenever I try to drive the high-side MOSFETs I get a voltage of around 40 mV in the midpoint between the high and low side of the bridge (e.g., OUTU). When looking at the signal through a oscilloscope I get the attached outcome. Does anybody know what the issue could be? Am I missing something in the control logic driver to enable the OPAMPS?Also, when I disable both output compare signals (OC1E, OC1NE), I get a voltage in OUTU of around 11 V (supply is 24 Vdc). Is this correct?Hope that everything is clear. 

Hi there!I'm using an STM32F746 disco with an OV9655 camera module. I have already configured all necessary peripherals: LTDC, FMC and DCMI.What I want to do exactly is tell the camera in which buffer I want it to save the image. In the meantime, process the previous image using the CPU. When I finished processing the image, I want to tell the LCD to display it. Maybe it will better br understood if you see this: while (1) { // HAL_Delay(500);  //DCMI->CR |= (1U << 0);  switch (sequence) { case SEQ_1: /* 1- Capture -> Buff_1 */ Take_a_frame( buff_address[0] ); sequence = SEQ_2; break; case SEQ_2: /* 1- Capture -> Buff_2 2- Pocess Buff_1 */ Take_a_frame( buff_address[1] ); processar( ); sequence = SEQ_3; break; case SEQ_3: /* 1- Capture -> Buff_3 2- Process Buff_2 3- Buff_1 -> LCD */ Take_a_frame( buff_address[2] ); processar( ); Show_frame( buff_address[0] ); sequence = SEQ_4; break; case SEQ_4:

Where can I download SPC5-UDEDEBGPLS JTAG debugging software! Not available on the official website! Can you give me a download?

According to the user manual (st (dot) com/resource/en/user_manual/um2115-discovery-kit-for-lorawan-sigfox-and-lpwan-protocols-with-stm32l0-stmicroelectronics.pdf), you can optionally close SB13 to get a 32MHz clock signal to the MCU instead of attaching your own external clock. However, when selecting the clock configuration for the STM32L072CZYx the HSE crystal freq is only allowed up to 25MHz and I see similar information in the datasheet for STM32L072xZ (st (dot) com/resource/en/datasheet/stm32l072cz.pdf). Maybe I am just misunderstanding but it sure seems like the intent is for the TXCO to be routed to the PHY_OSC_IN pin on the MCU in some applications, but the MCU is only rated for 25MHz

I build SBSFU using X-CUBE extension for STM32F769I-DISCO. Flashed the "SBSFU_UserApp.bin" file using STM32CubeProgrammer. Now I need to send UserApp.sfb file via YMODEM without using Tera TermI used,stty -F /dev/ttyACM0 115200 sb UserApp.sfb >/dev/ttyACM0 </dev/ttyACM0Is there any extra parameters to be mentioned or is there any other way without using tera term?

I created a project in TouchGFX Designer and then I opened the project in CubeMX. It compiles successfully. But then I want to add UART function to my project. So I go to CubeMX and add UART function but when compiling it gives an error because the stm32h7xx_hal_uart.c and stm32h7xx_hal_uart_ex.c files were not added to Drivers\STM32H7xx_HAL_Driver folder. So I had to manually import them and it compiles fine.CubeMX should have a functionality to automatically add the corresponding files for each functionality.Now I have added FreeRTOS functionality and it's giving me the same type of error message, except I do not know what files to add since I am not too familiar with RTOS.The error message is so long that I had to take 2 separate screenshots, I hope you guys can read it and help me out.I suspect the problem have to do with missing files for FreeRTOS.

According to AN4144, page 14/28, the coefficient 'ke' is measured by turning the stepper and measure the phase voltage with a oscilloscope. For the coefficient 'ke' in V/Hz, which voltage normation should be used:Peak-to Peak, Peak or RMS?.

Hi, I have an application where the device must respond to another device as a part of UART communication @ 1 sec. However, at the same time to log 200 bytes of data upon update of a variable, I need to log it into Flash at Sector 11 of STM32F205RGYX_FLASH MCU so reprogramming Flash takes 1-2 sec of blocking erase cycle as stated in the datasheet, and then by it missed to respond to messages from another device also observed timeout at another end. ​Can we have any mechanism that reduces the erase cycle time for Sector 11 or any optimized way out to manage communication and reprogramming flash simultaneously?Thanks,
