Hello everyone,I need to get some information about the power consumption of the STM32 Nucleo-64 with STM32F401RE MCU.The board is powered from the computer's USB port.I created a project in which the main while loop is empty, all peripherals are disabled and the HCLK frequency (from PLLCLK with HSI PLL source mux) is 84 MHz.I used a USB Digital Tester J7-c (between the board and the pc's USB port) and I obtained this values:5.04 V; 0.05 A; 0.29 W; 92 Ω.Changing the HCLK frequency from 84 MHz to 42 MHz, I obtain this values:5.04 V; 0.04 A; 0.25 W; 108 Ω.But if I use the PCC (Power Consumption Calculator) tool with these step parameters (RUN mode, power scale: scale2, memory fetch type: flash, VDD: 3.3 V, voltage source: battery, CPU freq.: 84 MHz, all peripherals disabled) I get a step consumption of 20.2 mA (= 0.0202 A).Instead, with these step parameters (RUN mode, power scale: scale3, memory fetch type: flash, VDD: 3.3 V, voltage source: battery, CPU freq.: 42 MHz, all peripherals d

I'm looking into calculating the timings for the brk filters for the TIM1 periphery. Mentioned there is the "tim_ker_ck" and the "tim_pclk" respectively.I cannot seem to find any information on where these come from.The clock tree in the RM says that TIM1 is connected to the APB2 using PCLK2, however there's nothing on how PCLK2 translates to tim_ker_ck or tim_pclk.

Hello,I have a very strange behaviour with the I2C bus of a STM32G431.I try to communicate with a MLX90393 of Melexis. I had some problems to get the measurements, after a Start measurement. The MLX90393 returned an error code. So I checked the signal with a signal analyzer.The signal look like this:  So the voltage of the SCL signal in white (digital measure at the top and analogue at the bottom) has a voltage drop to 1.6V at the end of the frame ! What is strange is that for other frames I've absolutely no problem. For example here I try to get the measurement from the sensor: The SCL signal is stable until the end.SCL and SDA are pull up on my board with 10k resistors and the frequency is set at 100kHz.I had previously used a STM32F334 on the 1st version of my board with all the same components (only the tracks are of cours a little bit different because the footprints of the F334 and the G431 are a little bit different) and I had absolutely no problems.I am able to w

hi come across these code using register programing, STM32F411 Nucleo bd, anyone can advise how does the (AF07<<4) and (AF07<<8) relate to UART2 PA2 & PA3? please advise..  #define AF07 0x07 GPIOA->AFR[1]|=(AF07<<4)|(AF07<<8); //ALT7 for UART2 (PA2 and PA3)  

Hi,I have read thoroughly RM0454, STM32G070CB datasheet and AN4187 in order to understand how to configure the DMA and DMAMUX in order to feed the CRC peripheral with FLASH data using the DMA (with CPU it is working but way slower than expected).I don't understand how to start the DMA requests through software, is there anyone who had successfully done it on G0 ?P.S. I don't do Cube and I don't want to do it for various reasons...

however, pwm1 doesn't output pulses. I think timer1 stop comparing output if calling Stop() function. Anyone has idea to implement this? Thank you.

Angle of incidence webinar question follow up… Original question - What angle of incidence performance information is available for these devices?  More detail - For multizone FlightSense sensors, looking into the corner of two walls for example or at a concave/convex  surface, each zone is not perpendicular to the sensor.  At high angles of incidence I assume the distance result from that zone will the average across the area of the zone.  Is that correct?  I'm assuming that at very high angles the histogram function might start to come into play, perhaps not, but if so what angle would the histogram function start to think there were multiple targets?  Or does the histogram functionality recognize that the distribution is kind of linear so the surface it's viewing must be at some angle?  If it does recognize that it's at an angle does it use this information for the average distance to the surface and or to calculate the estimated centroid of the su

Hi,I have a project based on MIPOT 32001506xxx radio module.The 32001506xxx is a multi-protocol sub-GHz radio module based on STM32WL55JC microcontroller.I need an example to follow to help me use the radio module as a "simple" LoRa modem.Thanks in advance

Hello allI have a STM32H730 project on a custom board.I have two W25Q16JW 2MB Flash connected to the OctalSPI in Dual-Quad mode.I have created a Flashloader ".stdlr" for my external Flash - its all working great in Cube Programmer and I can erase/program/debug a application from CubeIDE too.I have an Application program running in my External Flash (XIP mode) - I can debug this project fine.I have a small Bootloader program running in internal STM Flash (128K Flash) - I can debug this project fine. My issue is when trying to debug both .elf files going from from Bootloader to Application.(Reference : https://github.com/ethanhuanginst/STM32CubeIDE-Workshop-2019/tree/master/hands-on/09_BOOT-APP)I can start CubeIDE debugging in the Bootloader, step through my code and place breakpoints, but when I step into the Application and try and single step, or place a Breakpoint, I get this message; Error: Failed to set breakpoint at address: 0x90003da8.Error: Failed to set more brea

Hello TouchGFX Community,As part of my project, I'm developing a menu system within a TouchGFX application. The menu is intended to display either ToggleButtons or standard Buttons based on configurations set by the user. The aim is for the UI to dynamically adapt to these configurations, showcasing different functionalities as per the user preferences.I have read, that creating UI components dynamically on the screen at runtime is forbidden by TouchGFX design, however I've been exploring the possibility of dynamically generating these components before the screen initializes, tailored to the user's setup.I've had success with dynamically creating buttons pre-initialization, but only when they are of the same type, so I could keep them in the same array/vector.I know that the other route would be to predetermine all possible buttons in the .hpp file and manage their visibility according to user configurations, but I would prefer to avoid this method to save some of that memory.Given th

Hi !  I am very happy to start STM32F1 Series  for IOT projects. So i have experience of arduinoide software tool and STM32cube is new for me so which one will be best for smooth work ?

I have a monochrome display and use the framebuffer B/W with one bit per pixel. With the framebuffer and the TouchGFX Designer I can display text, but I have problems with small black and white images or e.g. a progress bar. Either only a black block or a black block with white highlights is displayed. But nothing usable. Has anyone had a similar problem and found a workaround?

I have tried every solution mentioned here. I have also contacted my friends and family members whom have tried to download this software and other libraries (CubeIDE, CubeMX, F1, F4, F7 and H7 Libraries). Same issues I need help urgently as I need to set software up as I have shifted to a new PC.    

Hi all,We are using an STM32H730IBK6Q.PA10 is not configured and STM32CubeMx generates code that initializes the pin as "Analog" as expected.Now if we enable USB (specifically, when setting `USBx->GCCFG |= USB_OTG_GCCFG_PWRDWN;`), that pin goes high, which is to me unexpected since AF10 (OTG_HS_ID) is not configured.Is there any way to tell the USB PHY not to attach a pull-up to that pin? It seems like it gets hijacked even if not configured. In the block diagram in the reference manual, that pin is mentioned, but I was under the assumption that if it is not configured as OTG_HS_ID in CubeMX, it would not be touched: As a workaround, I have configured it as GPIO output and set it to RESET, and that works, the pin stays low and USB communication is operational. Do you see any drawbacks with that? We operate as a USB device (not host) at all times.Thank you and best regards!

Hi, could I please get access to the 3D CAD Models for the LPS28DFW and VL53L4CD products? On both of their "CAD Resources" page you only offer the PCB Footprint and Symbol and not the 3D Model. I need to utilize the 3D model for designing a component that utilize both of these sensors. The datasheet dimensional information provided is not sufficient for this. Any help with this would be greatly appreciated. Thank you

UM2884-Rev 3, chapter 5.5 Results interpretation, shows in table 4 (list of available target status) a short description of the target status 0 to 13 and 255. Question 1: Our application sometimes also shows status 14, which is not described there. What is its meaning? Question 2: Some of the short descriptions are self-explanatory, others are not clear. Is it possible to provide a more detailed description that explains the status in more detail, i.e. what it really means, under what conditions does it occur and what is recommended to avoid it?

HAL_ADC_Start_DMA() takes a pointer to a uint32_t buffer, but the cubeMX can configure the DMA for word, half_word or byte.So therefore you can only configure the DMA for word transfers?I was setting the cubeMX to half_word or uint16_t and using 12bit adc, but I noticed the compiler warning about HAL_ADC_Start_DMA() taking a uint32_t.It is simple for me just to use a uint32_t buffer, but am I missing something?
