I'm looking to use a ITS4200S-ME-P relay to switch a high voltage signal and would like to control that via a UART. Per the datasheet this relay, "can be switched on and off with standard logic ground related logic signal at pin IN."

SetupSTM32G491KEADC1 Input Channel 3 using Pin PA2Vdd = 3VRC-Filter at the ADC input with R = 33 Ohm, C = 330 pFObservationWhen measuring the voltage at the ADC input with an oscilloscope, we see the voltage drop caused by switching the input signal to the SAR-ADC capacitor (C_ADC). This voltage drop and its settling depends on the used RC-Filter (values see above).We also observe that if the ADC input voltage is around Vdd/2, the voltage drop suddenly jumps by factor 2. Namely, if we compare the voltage drop at input voltage 1.45V with the voltage drop at input voltage 1.52V, the voltage drop is doubled for the input voltage 1.52V (see the plot in the attachment).However, if the capacitor of the ADC (C_ADC) is constant and the capacitor is completely discharged during the conversion phase of the ADC, we would expect only a linear dependency of the voltage drop to the input voltage of the ADC.Question(s)Is there an explanation for this voltage jump at Vdd/2 (and possibly other other vo

Hello,i use spc58ec80e1 in our project.

I have a STM32MP157C-EV1 board.Can i upgrade STM32MP157C-EV1 board to STM32MP157F-EV1 only removing TM32MP157C processor and reinstaling a new TM32MP157F processor?If not, how can i upgrade MB1263 MPU subsystem daughterboard to the last microprocessor family?

HiI'm using STM32H750VBT6 with W25Q32 QSPI external flash memory from Winbond and I'm using Keil Microvision IDE with ARM_CC Compiler.I'm trying to execute my whole project from the QSPI flash directly (which is called XIP). I know that I have to configure QuadSPI peripheral properly before executing code from the memory mapped QSPI flash and I'm doing it in SystemInit() function, so I have to map the SystemInit or system_stm32h7xx.c file to the default internal flash address and change the main() address to the QSPI flash (which is 0x90000000 in my case).The problem is, how I can change the main() base address and execute it from the QSPI flash after configuring QuadSPI in SystemInit().And what should I do with VTOR? Do I have to leave it with the default value?RegardsFarbod

Hello everyone,i am planing to use an STM32 microcontroller in a project and would like to have a debugger on the same board. I then have to use another microcontroller ie. STM32F103CBT6 the same as used on STLINK-V2-1 on Nucleo boards, which will act as the debugger for the actual microcontroller. But this need to be flashed with the right firmaware to do its job.I have searched everywere for an original firmware of STLINK-V2-1 but did not find any. How can i find an official and original Firmware for STLIN-V2-1 debugger?Thanks alot!

Hi,I'm working on the FW for STM32H725VGT6 MCU and something strange is happening.I've created a simple project with cubeIDE (with usart2 and a GPIO to toggle) and the code created and compiled with no issues. After uploading the code with debug mode and running it, everything looks regular and according to the IDE the code is being executed (a test value being increased within the while loop and I can see its value changing in the "watch" window) but actually the MCU is not responding, there's no prints on the UART and the GPIO is not being toggled.I'm writing the MCU with the STLink of STM32H7 nucleo board.I'm not new to STM32 MCUs nor to cudeIDE and I never came across such thing.Also, the boot0 pin is tied to GND.With the nucleo everything was OK and had no issues.I remember that the first time I programmed this specific MCU the STM32CubeProgrammer tool send me a message about the option bytes but I don't remember what this message was. There's a chance this issue related to t

Hello,I'm new to using this ecosystem and I'm having trouble finding resources on how to get my ethernet working so that I can connect to AWS IoT. I'm not really sure what is platform specific or not in some the examples I found so I was wondering if there was a easy place to find this information.

I am a hobbyist that only has basic oscilloscope and function generator that is (according to AN5042) not accurate enough to tune the HSE crystal. Is the HSE crystal in the NUCLEO-WB55RG pre-tuned?

Hello everyone.what the DD-out pint is used for on the TDA7376B?Does it cancel out the channel when it detect clipping on that channel?

It appears like the board design project files link is not linked to the proper files. When I click it, I get BOM info. I am looking for the Altium project files for the 32F746GDISCOVERY  board.  Can someone please let me know how I can get the Altium files for this board? Thanks,Dan

Hello, I have been trying for 2 days to read my hardware button from the STM32F746G board and change the color on the display. Unfortunately, all tutorials are for older versions where the file ButtonController.hpp still exists, but in TouchGFX 4.21.1 this file is not generated. The button is set up as BTN_USER with a pull-down in Cube MX. In the .touchgfx file, I have added"PhysicalButtons": [ { "Key": 1, "Name": "BTN_USER" } ], I also cannot manually call Screen1ViewBase::handleKeyEvent(uint8_t key) because I always get include errors. It can't be that difficult to read a physical button. Screen1ViewBase.cpp: void Screen1ViewBase::handleKeyEvent(uint8_t key){if(1 == key) { //Interaction1 //When hardware button 1 clicked change color of box1 //Set RGB color R:255, G:0, B:0 on box1 box1.setColor(touchgfx::Color::getColorFromRGB(255, 0, 0)); box1.invalidate();

STM32F070RB stepping Y, with a 24MHz crystal as HSE. No LSE.In the Cube, enabled PLL sourced from the HSE; SYSCLK goes to 48 MHz.Then, as soon as I run thru HAL_RCC_OscConfig, debugger loses connection and I don't know what the chip does.​So I've switched the sysclk mux to HSE without PLL (24 Mhz), and then whole SystemClock_Config() passes well and everything looks good.​So I thought, 48 MHz is too much for this board. Enabled PLL again, with pre-div 1/2, to get the same 24 MHz. It fails again.What can be the problem with the PLL? The board runs well at 24 MHz from the HSE, so the oscillator is good?

I am trying to use I2C4 Pins PD12 (SCL/D15) and PD13 (SDA/D14) but cannot get it to work. I used CubeMX to generate my project. Also, I am using the Cortex M7 for the I2C4 connections. Please tell me how I can get I2C4 to work with the  STM32H745 Discovery Kit

Hi, I am working with STM32F407VETx and it has total 192kb RAM, but its split into 3 regions:#define SRAM1_BASE 0x20000000UL // SRAM1(112 KB) #define SRAM2_BASE 0x2001C000UL // SRAM2(16 KB) #define CCMDATARAM_BASE 0x10000000UL // CCM(core coupled memory) data RAM(64 KB)   My question how do I use all those 3 regions?I assume 1st region (SRAM1) will be used by default by compiler?Can I simply use 2nd and 3rd regions (SRAM2/CCMDATARAM) by assigning address to variable?static uint8_t *Cache2 = (uint8_t *)0x2001C000; //16kb sector2 static uint8_t *Cache3 = (uint8_t *)0x10000000; //64kb sector3Also how is IRAM2 used by compiler? And why there is no IRAM3?

I saw some tutorials with STM32 IDE 1.11.0, > When typing for the variable or function name, it makes a list and selected if found.and I don't see it doing that; where is the configuration in preference top enable it or was is it from the plugin feature? I have checked the IDE manual and could not find it there.

Hello,We are designing a board with an STM32H7B0VBT6 and USB3320 USB HS-transceiver. The MCU will run at VDD=1.8V. In AN5307, p. 11 it is written:"On some packages neither the VDD33USB pin, nor the VDD50USB pin are available, it is the VDD pin which supplies the VDD33USB through an internal connection. In this case, VDD is constrained by VDD33USB and must range between 3.0 V and 3.6 V."The package that we use does not have these pins. However, I expect that the statement above only applies when using the internal FS transceiver, which we are not: We are using an external HS-transceiver through ULPI.Is it correct to assume then that in our situation we can use VDD=1.8V?
