Hello,I am working on STM32H745 controller. I want to share a variable between M7 and M4.Example: Variable named counter will be updated by M4 after some period and same has to be read by M7 for further processing.Can anyone help me with suitable app...
Hi everyone,I have configured my ADC on STM32F405 in Scan mode to read 5 channels. What I like to do ist to make a single DMA transfer to sample the 5 channels more than one time (e.g. 10x5channels = 50 elemet DMA transfer) To average the data after ...
The output push-pull implies either 0 or 1 - never floating. When do we use the output push-pull with pull-up or pull-down capability? What is the application for the output push-pull with pull-up or pull-down configuration?
Hi. Setup is simple:TIM2 creates the ADC_EXTERNALTRIG_T2_TRGO signal, which starts ADC. ADC is configured to use DMA to transfer the data to the buffer. hadc1.Instance = ADC1;hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4;hadc1.Init.Resolution ...
Hey Everyone,I am new to STM platform and dont have much experience with Embedded C. Currently I am stuck at PWM. First Things First:I am using STM32L052C8T6 MCU with a 16MHz external Crystal Connected.I am using STM32CubeIDE v1.12.1I have a photodio...
Hello everyone,I am developing a small program with a relay which has a data, power and ground input. This is powered at 5v and I have it connected to the GPIO PA0 output.My code is as simple as creating a task with FreeRTOS as follows:void StartDefa...
Hello everyone! I have been reading the user manual for the u575 processor and found out that there was a cache memory there. But I have absolutely no clue how does it work and how to implement its support in code. Does anyone know any article or som...
Hi all, (STM32U575..) we have the SRAM2 ECC active on reset by the according configuration of the flash option byte. For testing purpose I switch off the ECC by using the HAL_RAMCFG_StopECC(&hramcfg_SRAM2), manipulate one cell for a one bit error and...
Hi!I'm using STM32F217IGT.I want to know changing VDD anytime.I think.1. change firmware correction VDD(3.3V firmware or 1.8V firmware)2. change system clock configuration void SystemClock_Config(void) in main.c --> 7WS Thank you!
We have had this part on order from Mouser for over one and a half years, and Mouser cannot get any details on when ST will deliver. ST, is this part still in production? If so, why are you not allocating any to your authorized distributors in the US...
