Solved

Hi, I am just wondering would it be ok to operate this IC with 52 to 55V supply? Hoping to use this with a 52V battery without the trouble of designing a new power supply.Clipper circuit will also be incorporated to eliminate any voltage spikes.Regards,Dan

I would expect obscured controls to not respond to clicks.

Hi, I use STM32F407 to acquire and process data from sensors, this data is very large approximately I need to define array (float Data[12][15000]) with 12 row and 15000 columnbut, STM32F407 mcu can't define this array.Did I exceed the maximum size of data memory ? and how I can determine the maximum size of an array of type float?Thanks..

I am trying to follow the DM00570145 and validate on target (STM32F746 Discovery Board, XCUBE-AI 6.0.0, toolchain: STM32CUBE IDE), I cannot get the output listed on Figure 61. "Layer by layer results - Validation on target", especially the "ms" running time on each layer. I also tried Keil MDK toolchain, no luck. I opened the ai_stm32_msg.txt, no such information. Not on the terminal (I used putty) output.

Hello,I'm working on a BLE project on a STM32L072CZYx MCU and there is an example of a profile that suits my need but it is on another MCU, the STM32L476RG. I want to port the code from that MCU to mine but I don't really know how to do so... I've checked a tutorial on porting code but they use CubeMX and more specifically the .ioc file of the MCU I want to port the code from. The problem is I don't have the .ioc file...So I have 2 questions regarding this :Is it possible to port the code withour using CubeMX?Is it possible to generate the .ioc file from the code?Thanks for your help

Using:Latest STM32CubeIDENucleo-64 G071 (Cortex-M0+)GNU Tools for STM32 (9-2020-q2-update) (default)There seems to be a problem multiplying long numbers. Here's what a multiplication of two 32 bit ints looks like.And this is what a multiplication of a 64 bit with a 32 bit int looks like. It works, but in addition to writing the result it also writes a bunch of junk in the memory addresses preceding the variables. `bl   0x80004e8 <__muldi3>` seems to be the culprit here.

I currently am working with a stm32L010K4 mcu, but i have a startup script for stm32l010xB (startup_stm32l010xb.s). Where can I find a startup script for the stm32L010K4 mcu -- I'm guessing the name is startup_stm32l010x4.s ?

Hello,I use SM32F103ZH6 MCU.I'm trying to send log (i.e. text) messages from my board to host PC on a UART2 using HAL_UART_Transmit_DMAproblem: 2 successive calls to HAL_UART_Transmit_DMA, only last call gets executed.logging function (sends text to host PC)void LogEvent(const unsigned int EventType, const char* format, ...){  va_list arg_list;  va_start(arg_list, format);  vsnprintf(LogString, MaxEventTextLength, format, arg_list);  if (EventType == EventType_Info)    strcpy(pcLog, "Info>");  else if (EventType == EventType_Warning)    strcpy(pcLog, "Warning>");  else if (EventType == EventType_Error)    strcpy(pcLog, "Error>");  strcat(pcLog, LogString);  strcat(pcLog, "\n\r");  HAL_UART_Transmit_DMA(&huart2, (uint8_t*)pcLog, strlen(pcLog));}UART2 is setup as followinghdma_usart2_tx.Instance = DMA1_Channel7;hdma_usart2_tx.I

In the TouchGFX program, there are Model, A_Screen, and B_Screen.It's working in A_Screen, and it's working in Model::tick()When I have time, I want to move the screen to B_Screen.To do this, I want to know what to do in Model::tick() to switch from A_Screen to B_Screen.If anyone knows how, ask me for advice.Thank you.

I think I dove in a bit over my head.I made a custom stm32f0 board that measures and logs a magnetometer through SD card and CAN. It was originally prototyped and tested on the nucleo stm32f042k6 and I tried to copy the essence of it into kicad and make the pcb. I broke out the SWDIO and SWCLK pins, but did not realize that I should've included the reset circuitry.I tried flashing the board with the stlink v2 debugger/programmer and received theError in final launch sequence:   Failed to start GDB server Failed to start GDB server Error in initializing ST-LINK device. Reason: (4) No device found on target.message. Reviewed forums and learnt a lot of info that I should've researched before doing this :D and tried the following:only had VDD (pin19), GND(pin20), SWDIO(7), and SWCLK(9) connected at first, so tried connecting VAPP, but have only tried connecting it to VDD (3.3v)tried pulling down and pulling up NRST, and connecting NRST to ST Linktried pulling down & pulling up BOO

When reading the I2C bus with DMA it is followed by a NACK. Do i have to clear it somehow in the DMA1_Stream0_IRQHandler ?

I am looking for an expert to help me with I2C bus on STM32F407IGT. I2C3 is working as expected and I would like to make working also I2C1 and I2C2 which I have problems with.I am using the same initialization regarding registers and I can see the right values on the right places (addresses) but I don't get any interrupt on I2C1 and I2C2. I set the start bit and a value in DR register but I can not see any clock or signal on pins. Any idea what to check?

I am writing in reference to RFID tag reader project that we are working on it. We have studied it and this gives us insight how GUI is working and how data is flowing from GUI to RFID pcb.Inspired from your GUI software we are trying to develop our own custom API without using Qt framework. We would also appreciate if you could please provide us individual protocol structure or protocol stack for each tab and button in GUI since we are finding it difficult to trace the protocol structure for tabs and buttons that we want to use in our custom API. 

Hi, I have already a ioc file for my board. So I created an application template for Touchgfx Designer using it. But when I generated the code in Designer, I was getting an error about that ioc file couldn't be found. So I put the ioc file under the project file. Then I got an error about that uvprojx file couldn't be found. So, what are the needs to create a app template?

I use passive RFID tag with NFC03A1 card reader, I have create a little program to detect RFID tag, the range is up to 5 centimeters. Is there a way or a configuration to increase this range ?Thank you in advance.

I'm using the demo code ST25R3911B-DISCO, and I don't find how are making the request for other board by RFID, I want to know if the code using interrupts to make this request each time gap or if this code makes a request just when calling a function?  

environment:STM32CubeIDE Ver1.6.0Thank you for helping.How do I add image compilation options?Thank you.

MCU: STM32F769Thank you for helping.I may want to reset the microcontroller while the program is running.What kind of method is there to reliably reset the microcomputer in terms of software?Thank you.

Hello,I am trying to generate the code for a neural network with STCubeMX, and I'm following the manual you have posted here (https://www.st.com/resource/en/user_manual/dm00570145-getting-started-with-xcubeai-expansion-package-for-artificial-intelligence-ai-stmicroelectronics.pdf). I follow all the steps, but, when I have to select the USART3 on the "Platform Settings" configuration tab of X-CUBE-AI, there is no "Plarform Settings" tab. I attach some images. This is how it is supposed to be: This is what I have:  As you can see, the USART3 is correctly configured:  I am using version 6.2.0 of STM32CubeMX and version 6.0.0 of X-CUBE-AI. Could you give me any help?Thanks.

I using in my project today the ISO 14443 Protocol, but I Will need to arrive at the highest transmission rate, I believe that ISO14443-4 could give me that rate.Is it possible to implement ISO14443-4 in ST25R3911? What is the function that I can use to read this protocol in the demo code of ST25R3911-disco? 

hi, i am working with an example from the book Mastering STM32 written by Carmine Noviello.The example is the 6th of chapter11, it is about Input capture mode.I have a nucleo board STM32F401RE and i am building examples with STM32CUBEIDE tool.I have configured two timers:i use TIM1 in DMA circular mode to blink the LED PA5, which is high every 50khz.i want detect this frequency by connecting the led to channel 1 of TIM3 in input capture mode.TIM3 clock is connected to LSE through the MCO pin, which is running at 32768 hz. I configured TIM3 in DMA circular mode so that when the LED is high, the content of CCR is trasferred to a 16bit Captures array of two elements(Captures[2]).The DMA transfer is of halfword size since the CCR1 is a 16 bit register.The global variable captureDone is set to 1 by the HAL_TIM_IC_CaptureCallback() callback function, which is invoked at the end of the capture process.When this happens the frequency of the sample signal is computed using the following equatio

Hello,I am designing a system of multiple VL53L1X sensors placed around a drone. My question is whether two sensors are closed and oriented towards the same direction , is it possible that the VCSEL signal from one could affect the measure computation of the other ?Whether it's the case, exists it an angle (45°/90° of direction difference) where these interferences will disappear ?Another point is with a timing budget of 20ms for example, how many time the sensors radiate the signal before computation ?Thanks for your future help.
