Hello,is it right that STM32WB55CGU6TR is already pre-loaded with FUS v1.2.0.0?

Dear Team, I recently created a custom PCB where I wanted to implement the STUSB4710(A) for charging a phone and other accessories. The STUSB4710 should be plug and play without the need of configuring the PDO because it is already selected. I based my design on the valuation board of this IC: STEVAL-ISC004V1. I will attach a file with my schematics.So when I attach my Samsung A53 it will say that is is attached to a fast charger but when I look at the ampere app I charge with a current of 200mA which is almost nothing.So I started measuring and encountered an issue where the VBUS has a stable 5V which is good, but there isn't any current running from the to the usb-c connector as I also saw in the app. I read some registers trying to find out what the problem is via I²C and read the register of the CC_STATUS (0x11h) I found this in the file that was posted in a other post. here I can see that I get the following value 0x89 which means: (0x80) twisted cc2 lines (OK), (0x09)&n

I am looking to implement back button to go back to previous screen (similar to UI on a smart phone). For this,1. Need to remember current screen before a button is pressed.2. In the new screen, when a back button is pressed, programmatically change to previous screen. It would need a common memory area where current screen can be saved. This information should be accessible from any screen so that it can be read when a back button on that particular screen is pressed. Here is a scenario:There is title bar with a button, say Button1.Screen 1 leads to Screen 2. Screen 2 leads to Screen 3. All screens have title bar with same Button1.Two ways to reach screen 3. First, by clicking the Button1 on title bar (a short cut). Second, Screen1 to Screen 2 to Screen3.Screen3 has a back button.When present screen is Screen1 and Screen3 is reached by pressing the Button1, if a back button is pressed in Screen3 then Screen1 should be reached.When transition is Screen1 to Screen2 to Screen3, if a

Hi everybody, I have been looking for the charateristics (like ppm/temperature dependency) of the LSE crystal included in the STM32WBMMG, but I have not been able to find on its datasheet.Is there another document I am missing where the information about the LSE crystal can be found? Thanks in advance! 

The PKA peripheral can precompte the montgomery parameter, which is documented as "R2 mod n". If I compute this offline with R being the normal (2 ^ b) [b the numbers of bits in the modulus n], I am getting a different result than what PKA computes. I did see there was a "computeR2.exe" for BlueNRG-LPS (also with PKA peripheral), but no source. Is there anywhere documentation or source code of how to precompute the "Montgomery Parameter" used by the PKA peripheral ?  

I am practicing reading L3GD20 data built into the stm32f411e-discovery kit. I use SPI1 to communicate with L3GD20. I watched on YouTube, they have instructions on how to use the void function HAL_GPIO_EXTI_Callback. I cannot call the void HAL_GPIO_EXTI_Callback function to read data from the sensor. Debug only receives the value from the bar but not the value read from the sensor I use pin PE1 (configuration: Rising edge trigger detection, Pull-up ). Below is an image of my code. I need help. Thanks everyone   

Hello everyone!I just started learning how to use the STM32WB-Chips on the Nucleo-WB55RG and followed this tutorial: https://www.youtube.com/watch?v=Zgw3wRpGSRQ&list=PLnMKNibPkDnG9JRe2fbOOpVpWY7E4WbJ-&index=17After that I tried to make a function (following the steps mentioned in the tutorial above) which I can use in the main.c to send custom data to the PC. However when I call this function in the main loop the advertismenet  disappear and I cannot find the reason why. Can you guys help me with this?In the app_conf.h I wrote648 /* USER CODE BEGIN Defines */ 649 void ble_updateChar(uint8_t); 650 /* USER CODE END Defines */ ... 671 /* USER CODE BEGIN CFG_Task_Id_With_HCI_Cmd_t */ 672 CFG_TASK_BLE_UPDATE, 673 /* USER CODE END CFG_Task_Id_With_HCI_Cmd_t */In the app_ble.c268 /* USER CODE BEGIN APP_BLE_Init_1 */ 269 UTIL_SEQ_RegTask(1<<CFG_TASK_BLE_UPDATE, UTIL_SEQ_RFU, ble_updateChar); 270 UTIL_SEQ_SetTask(1<<CFG_TASK_BLE_UPDATE, CFG_SCH_PRIO_0); 271 /

Dear all,I've been following this video on YT on how to get the FDCAN on my discovery board (STM32H735G) to work: https://www.youtube.com/watch?v=sY1ie-CnOR0 . Note that this is the 2nd video of a series, if you want to watch it. Now, my problem is not with the video but with why the code doesn't work on my board. The full code you can find attached to this post. The code compiles and runs without a problem, however, when I reach the if (HAL_FDCAN_AddMessageToTxFifoQ(&hfdcan1, &TxHeader1, TxData1)!= HAL_OK)line in the while(1) loop the second time around, it throws an error. I have been unable to identify what the error is or how to solve it, however, I had a look at the pins with an oscilloscope to confirm the existence of a signal or the lack thereof. I did not see a signal. What I find interesting is that it succeeds the first time but only gives an error the second time around.Any insights and solutions are welcome!

I set the parameter of TIM5 of my MCU on CubeMX,the frequency of the clock is 72 MHz,PSC is 7199,ARR is 199,the information about my settings is below: TIM5 is used to output 4  channels of PWM to control four SG90 servos,TIM1 toTIM4 is used to control four Ultrasonic ranging module,I use this sentence to initialize four servos: I think these servos should turn to 0 degree,but in fact it turn to 90 degrees and stuck there,I don't know the reason why it happened.I hope someone can heip me solve this problem,it has been made me confused for several days 

How do I connect x-nucleo-lpm01a with STM32WB5MM-DK to test power?I am using the RF module from STM32WB5MM-DK and not the one from P-NUCLEO-WB55.I know that there is a video for P-NUCLEO-WB55. Is there a video/guide for STM32WB5MM-DK as well?   

Hello,Can someone at ST provide explicit, step-by-step instructions describing in detail how to generate a project for the STM32H755 with TouchGFX running on the CM7 processor? All the posts I've seen online seem to describe ways of hacking projects together involving copying, editing, copying .cproject files, moving TouchGFX files around, deleting simulation files, etc. I've spent days on this now and always seems to end up with a project that can't build because the tools can't find TouchGFX files because TouchGFX generated those files in the wrong place (according to where CubeIDE thought they should be). My board has a working SDRAM, working LTDC correctly displaying whatever I write to the frame buffer in the SDRAM, etc. I have regenerated this project countless times now but always end up in the same place.1. What tool should I be starting my project with? CubeIDE? CubeMX? TouchGFX?2. What should the project structure look like when configured properly? What does the project dire

Hello,I am struggling with the individual RX CAN Message Filter RXIMRx on SPC570S.First Question:Is there an Application Note available for the SPC57x Note like it is for the for SPC58x (TN1348).Second Question:I want to use the RX CAN Message Filter RXIMR0 without FIFO.How is the extended bit IDE and the RTR handled in the filter oris it ok to handle extended and standard format only with the filter-range.If so how ist RTR activated deactivated. Kind regards in advance 

Hi,For TrustZone enabled project (U5), TouchGFX configuration in CubeMX can't recognize enabled THREADX.Any ideas?Two screenshots attached:one for TrustZone enabled project setup and another one for the exact same but Non-TrustZone project.For the former it can be seen that THREADX option is greyed-out and cannot be selected, while for latter everything highlighted as expected.CubeMX generates correct project for non-TrustZone enabled project.TouchGFX version is 23.1, CubeMX is 6.10.0Thanks   

I have been struggling for a few days now with trying to trigger an interaction within TouchGFX (V4.23.1) via a hardware button.The board is a STM32H747i Discovery.

I have been reading a bit about neopixels and the communication protocol they work. I have been searching for a library for the WS2812B neopixel but could not find one that would work out of the box hence I have decided to write my own neopixel driver. This would also help me further understand DMA peripheral. It is worth mentioning that I use STM32CubeIDE as my development environment and I use STM32CubeMX to configure the peripherals.  When setting up my project I refered to the example below:https://controllerstech.com/pwm-with-dma-in-stm32/but I still could not get it to work properly. I suspect that the issues lies within the DMA.1.Clock configurationI have decided to use TIM2. According to the STM32F407 Block diagram (STM32F407 Datasheet ) , this Timer connects to AHB/APB1 hence I have set the APB1 to 48MHz to achieve the required Clock frequency for the neopixels. 2. Timer configuration: 3. DMA configuration: 4.  Full source code: &nb

In the context of a research project, I am using the STM32H743ZI2 microcontroller for object detection. However, I lack prior experience with camera interfacing and configuration. I am using a B-CAMS-OMV camera module. Therefore, I would be grateful for any relevant references or guidance to facilitate the successful implementation of this aspect of the project.

I'm trying to do some debugging using SWO on an STM32G474. After a very short amount of time no new packets are displayed in CubeIDE (usually after ~2500 packets). I limited the SWO frequency to various values between 100kHz and 8 MHz. Using an oscilloscope I can verify that the data is still being output at the correct rate by the MCU but no data is received by either the STLink probe or CubeIDE.I tried many combinations of settings (shared STLink, OpenOCD instead of ST-Link GDB server, reset mode, low power debug mode [I don't use low power modes], baudrate, etc.) and nothing worked.CubeIDE version 1.14.0.Debug log: STMicroelectronics ST-LINK GDB server.

Hello,I am using STM32U575 and would like toimplement a PWM output. This should also work in Stop2-Mode.Clock for the LPTIM is LSE. It works with LPTIM1 and 3 without any problems.To generate a PWM in Stop2-mode, I use the LPBAM with LPDMA. Now I would try it with LPTIM2, too. But it hasn`t work so far. Is it even possible? LPTIM2 is connected to a different bus than the other LPTIMs.The data sheet states that autonomous mode should be possible with LPTIM2? Thank you in advance for your reply.   

page 1320; timer 2 input pwm mode"1. Select the active input for TIMx_CCR1: write the CC1S bits to 01 in the TIMx_CCMR1 register (TI1 selected).2. Select the active polarity for TI1FP1 (used both for capture in TIMx_CCR1 and counter clear): write the CC1P to ‘0’ and the CC1NP bit to ‘0’ (active on rising edge).3. Select the active input for TIMx_CCR2: write the CC2S bits to 10 in the TIMx_CCMR1 register (TI1 selected)." shouldnt it be "write CC2S bits to 01 to select TI1" ? 

Hi,In the project that I saved-as (to rename) the DEBUG was set to JTAG (5 pins).After updating to STM32CubeMX version 6.11.0 I observe the JTAG (5 pin) option is unavailable.Below change (i.e. switched DEBUG to JTAG (4 pins))  was made by software automatically while saving the file.Regards,Rajeev
