STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I am using FMC on STM32F765NIH7. Using the HAL library for FMC, which copies the data byte by byte into the NAND register, what happens is that almost any interruption during the data exchange can lead to incorrect receipt of them. So that interrupts...
I have fail using multi UART while using with the ring buffer,but using the HAL function testmulti uart is fine,i using the Keil c(MDK) complier check and i test if cnacel the HAL_UART_Init(&huart3) or other one is fine ,and i look for other of the s...
Hi,I would like to know about the STM32F091's RTC accuracy and frequency error information.Is the RTC accuracy or frequency error factor affected only by crystal?Is the RTC accuracy or frequency error factor affected by MCU itself?Is it any ST docum...
Hello, I am using Nucleo-H743ZI ,I am using timer1 to trigger ADC.My APB1 clock frequency is 240MHz and my ARR register is 240 of timer 1. So my sampling rate of ADC should be 1Msamples/sec. To check it I am toggling a pin whenever ADC conver...
(1) cannot run at 84Mhz, it will stuck at Error Handler RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_H...
I have few questions on STM32H745 dual core cortex M7 and cortex M4.i. What is the booting sequence when both the cores are enabled at the same time? Is there any application notes available in details.ii. How both the cores uses the same resource (R...
Hi everyone,I am using STM32G070 Nucleo board and work with I2C and use DMA to reload TXDR or read out RXDR. I built up a master that shall also be able to receive from other masters. Everything works fine so far. Now I want to limit the number of by...
Hey,I am trying to modify some compiler/linker directives from IAR to GCC. I think I already managed to solve the first two obstacles:1 - In order to not initialize a variable saved in some register:static volatile __no_init uint32_t SystemInfoFlags;...
Hi,i'm needing to save the date and time on RTC backup register constantly (like once every second) in order to restore the saved time if the MCU was reseted, but im not sure if this registers could be written so constantly.
I would like to change the pin configuration from GPIO Input to INPUT_CAPTURE_MODE_Channel in the code (dynamically). How to achieve this ?I'm using STM32F103CBT6.Please Help. Thank you.
