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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
A simple question.I have loaded & run the NUCLEO-F401RE \Projects\STM32F401RE-Nucleo\Examples\UART\UART_Printf example.The project sends printf() to COM.I have cut and paste the __io_putchar(int ch) code into my own project.__io_putchar() does not g...
I have a microcontroller that restarts by switching a switch to PE1 (Pin 142).The switch is grounded and has a resistance to VCC. PE1 is connected between resistor and switch via a low-pass filter.I'm worried that VDD (pin 144) has a cold solder join...
Hello,I have an application, where I need ADC samples at a fixed rate, if the device is running. So, I can do a ADC self-calibration at start up and while idle, but not while the application is running.The application can run for several hours and th...
On an STM32F103 I configure SPI in 16bit wide mode and set up a DMA transfer to transmit one word:SPI2->CR1 &= ~SPI_CR1_SPE; SPI2->CR2 = 0; SPI2->CR1 = SPI_CR1_SSM | SPI_CR1_SSI | SPI_CR1_DFF | SPI_CR1_SPE | /* Some baud rate flag...
Hi I am using the RTC on the STM32L433 with battery backup. After the date/time been set and running , then either processor reset or repoert the unit the date/time resets to the default time. As it happens even after reset (power not disconnected) ...
I want to reverse the Bits of a unsigned long data that is acquired by serial port. I used __RBIT() function in Attolic Truestudio but it does not work . I found during debugging the ARM_ARCH_7M is not defined .I compiled similar code in the KEIL , ...
Hello, i have probem with backup registers, which are powered from VBAT pin on Dicsovery board.First problem was CubeMX init, where i can't choose LSE source, because the value of clock box, was not active. I tried differend things like change txt c...
hello everyone !i'm using a nucleo board (NUCLEO-F401RE) to program a MCU STM32F301 placed on newly fabricated pcb; the mcu has never been programmed.i have disconnected the jumpers to use the CN4 connector. i have just connected the SWCLK (clock sig...
i have interfaced opt8320 optical sensor to stm32f446zet.I hav configured STM as master and Opt8320 as Slave. Can i initiate continuous registers read from sensor using I2c ?Please share suggestions regarding this issue.
I am more of a assembly guy. So I have problem in understanding the functionality of I2C control registers. It would be helpful if you could provide an outline or a pseudocode as how to write to a register or how to read from a register ? How to writ...
