I got an STM32H745I-DISCO board and am trying to get a program started with the TOUCHFX component, but I noticed that all the components are not available because "This pack cannot be used on the selected MCU".Is there a way to make it work? Is it a limitation due to the dual-core nature of the MCU, and that the CubeMX tool doesn't support it? I'd really like to avoid having to integrate it manually.

Hello STM Community!First of all, I would like to thank you to read my topic and enter in this discussion.I'm new with STM32, and it's the first project of mine that I really need to worry about energy comsuption.In my project I have sensor that Input =12V and output 4~20mA.I waas think to use something like figure below.However, I don't think is the best way to do when power consumption it's something relevant.So, with you guys have better suggestion I would aprreciate! 

I wish to make changes to a STEVAL-STWINKT1 which I bought, in other words I have to redesign to suit my application. The example projects works fine. I want to know from experts, is there a tool which will help me to write program or copy the example. Or any video which explains the step by step procedure?Thank you in advance, your advice will help me as this task looks very complicated. If I have to write drivers from the scratch, hope not.

Hello,No dev kit is available for STM32MP151x microprocessors, do you know if it is possible to replace the STM32MP157 chip by a STM32MP151 one on the STM32MP157A-DK1 ?I have read that STM32MP1 are pin to pin compatible, but I want to be sure and if someone has already done this, that would be interesting.Thank you in advance.Charles Blanchard

Hi, I've created a custom keyboard and so far all works good. I've just a problem: I want to use an OK button on the keyboard to copy the text edited to a text area in an other screen. I'm able to go to the other screen but when i do the second part of my goal, I've got errors. I think the problem is in the function getBuffer.-This is the part in customkeyboard.cppvoid CustomKeyboard::okPressedHandler(){getBuffer(); // function to save the actual entered textapplication().gotoScreen01ScreenNoTransition(); // if i use only this line the code work to change screeen}-Part in customkeyboard.hppvirtual void getBuffer(){// implemented in screen02_00View.cpp}-Part in the screen where the keyboard is definedextern Unicode::UnicodeChar keyboardBuffer[10];void Screen02_00View::getBuffer() // added to manage the entered text from temperature keyboard{Unicode::UnicodeChar* buff = keyboard.getBuffer();Unicode::strncpy(keyboardBuffer, buff, Unicode::strlen(buff) + 1);} -Part in screen.hppvirtua

I'm trying to implement a 10 us delay using TIM2. This delay is inside an EXTI interrupt handler.I am not getting a return at the end of 10 us.In the clock configurator, I used the max PLL clock possible, 64 MHz. Is this OK? I don't know what else to use here.Edited to add: the purpose of this delay is to allow the external pulse to settle before determining its value. I am currently watching for the EXTI interrupt and then giving a delay. Is there a better way to do this with the timer settings?Thanks,Priyavoid delay_us (uint16_t us){ uint32_t start = TIM2->CNT; while ((TIM2->CNT - start) % 65536U < us); // wait for the counter to reach the us input in the parameter}static void MX_TIM2_Init(void){ /* USER CODE BEGIN TIM2_Init 0 */ /* USER CODE END TIM2_Init 0 */ TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; /* USER CODE BEGIN TIM2_Init 1 */ __HAL_RCC_TIM2_CLK_ENABLE(); /* USER CODE END TIM

Hello,I am trying to use the memcpy function to transfer data from the ADC data buffer to a separate data buffer, but when I call memcpy, only the first 1400 of 6000 samples gets copied, while the remainder of the buffer does not get updated. I noticed this when I added a breakpoint after the memcpy function and when I output the new data on a DAC and saw the following on an oscilloscope, where the green toggle indicates when the HAL_ADC_ConvCpltCallback function is called, and the blue is the data being output by the DAC after being copied from the ADC buffer. The function being read at the ADC is a simple ramp function: I am wondering if there is any specific reason this may be occurring. I am using DMA for the ADC (Continuous DMA requests enabled) and a DAC on the STM32F413 MCU. The only thing being done in the callback is a flag being set.Thanks,MC

Hello ST Teams!Question, again! I'd like to know if the image "st-image-core" or "st-image-weston" are compatible with the "read-only-rootfs" from yocto append? (thud or dunfell) Well I've already tried on the st-image-core and bitbake compilation failed, saying something about user-fs.Any hints would be welcome!Have a nice confined day!

I have an application using a LSM9DS1 with the purpose of accurately measuring the rotational speed of a platter spinning at about 33 rpm.I measure the speed by taking readings from the gyroscope every 10ms. I did an initial calibration for offset and slope before that, but I would like to increase the accuracy by correlating the initial calibration with data from the magnetometer also.So I added an initial calibration step by reading the X,Y measures from the magnetometer every 30ms, calculating a heading using atan2(Y, X)*180/PI +180 , and measuring the time it takes to go from heading 50º back to heading 50º again.However, when I look at a log from the headings obtained, I see a not completely linear sequence of values, sometimes going back for 1,2 steps, before going forward again. Something like: 34, 36, 38, 33, 39, 40, 50, 45, 55, 60.....Any idea of what may be causing this ? Maybe I'm trying to take readings too fast ?I've set ODR at 80Hz

Hi! My name is Vincenzo.In the last week I devoted myself to study the example application written by ST for the ToF VL53L1 (VL53L1CB). I was interested in being able to better understand the MULTIZONES_SCANNING mode. In the example, the field of view of the ToF is divided into 2 zones. Based on this, I am attempting to write an application similar to ST's 2D LIDAR. I would like to divide the FoV of the ToF into 9 zones. At first I thought I had succeeded, but lately I noticed that periodically, some zones detect a particular high ambient value. The curious fact is that this "anomaly" of the ambient value seems to depend on the number in which the field of vision is divided. For example, if I divide it into 10 Zones instead of 9 I don't run into this anomaly. If I divide it into 8 I encounter the anomaly again, but it appears in a reduced form, but more frequently. In the most interesting case, the one in which I divide the FoV into 9 zones, I register ambient values ​​that are about 5

Hello,I am trying to set the clock frequency to max of 480 MHz. I tried 120 MHz and there is not problem with that. The block code is very similar for both, so not sure what is going wrong.I feel the oscillator fails and goes into an error state. Based on datasheet max speed is 480 MHz and PLLM, N, Q are set based on valid values taken from CubeMX.I also tried all possible value for "FLASH_ACR_LATENCY_15WS" since this is the only difference between 2 code blocks of 120 and 480.Here is USART output:[2020-11-15_10:56:03:539] Before.[2020-11-15_10:56:03:539]SYSCLK : 64000000Hz[2020-11-15_10:56:03:539]HCLK  : 64000000Hz[2020-11-15_10:56:03:539]PCLK1 : 64000000Hz[2020-11-15_10:56:03:539]PCLK2 : 64000000Hz[2020-11-15_10:56:03:539] AFTER  120.[2020-11-15_10:56:03:539]SYSCLK : 64000000Hz[2020-11-15_10:56:03:539]HCLK  : 64000000Hz[2020-11-15_10:56:03:539]PCLK1 : 64000000Hz[2020-11-15_10:56:03:539]PCLK2 : 64000000Hz[2020-11-15_10:56:03:574]Someth

Hello! Thank you in advance for your help =)I've just bought a STEVAL-BCN002V1B (BlueNRG - Tile), with the host board to Flash and debug, and i would like to know how i can easily program it. Questions:I've found this video where a STEVAL-IDB007V1 is programed using the BlueNRG - 1 navigator. Is there anything similar for my board? If yes, could you please introduce me to the first steps?How can i access examples and send them to the board? I would be very happy if i could do anything similar to this LinkWhat is STSW-BLUETILE-DK 1.3.0? Is it usefull for my porpuse? Is there any tutorial avaiable?My ultimate goal would be send/receive information from a cellphone with my BlueNRG - Tile and transmit this via I2C (or UART, or SPI) to a Raspberry Pi. Any idea how this can be done? I'm sorry for asking so many questions, but i can't find this answers anywhere.Best Regards,Danilo

Hi,I am struggling for a while to get the CDC_Host to work. Steps that I have taken are:Create a MX Cube USB Host HS port projectset correct frequencies 8Mhz for HSI, heap=1200 stack 800 (tried various values with no effect)Generate the code (eWarm and CubeIDE code - no difference when running)Flash to a Disco407 boardconnected the USB host connector to PB14,15 via a USB sniffer to a STM32F103 boardThe results I see is that the device enumerates on the host successfully (goes thru all stages and ends with set_configuration1 and getlinecoding packets).However when I send a USBH_CDC_Transmit API then that packet does not get send out. I did debug the code see below. I did find the point where the transmit fails to initiate the packet based on the CDC_Handle status (incorrect status code e.g. 0x81 instead of CDC_IDLE etc).main.c routine contains... /* Includes ------------------------------------------------------------------*/ #include "main.h" #include "usb_device.h" #include "usb_hos
