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...
Hi,I want to configure the DMA so that it transfers data from the GPIO lines (8 bit data lines) to the RAM buffer upon receiving a trigger signal on the timer capture input channel TIM1_CHI (PE9) . I am using stm32f446ze.We nees to acquire data regi...
Dear,I use SM32L152, I go to STOP mode regularly and as the possible source of waking up is either RTC or External interrupt. It works Fine until I change the System clocks from MSI 4 MHz to for example HSI on 16 MHz. If I change it, then MY MCU is w...
Posted on August 28, 2014 at 12:45I am using timer1 channel 1 as output compare, to generate a pulse of variable period.Desire output � In the beginning the output remain low for 4 ms(delay period) and then pulses of variable periods as 5.8, 3.6, ...
Hi all, I would like to know whether the write access to external flash is possible when the code execution is from external flash? When I tried to write on external flash HAL function returns driver busy, since it's been used in memory mapped mode f...
Posted on February 14, 2018 at 01:55Hello,I have a program using serial UART communicatons. I based the UART code on the example code UART_TwoBoards_ComDMA. The system seems to work correctly when it is in command/response mode. That means, I can ...
I'm new to working with STM32's so if I make any mistakes please let me know. I have the STM32F446RE Nucleo board and I'm trying to read two ADC channels (IN15 on GPIOC_05 and IN14 on GPIOC_04) and output the ADC values over USART 1 channel as fast ...
I am working with the STM32F769NIH6 microcontroller and it's communicating with a different processor using a home-made SPI-based protocol where the STM32F769NIH6 is the slave. The master clocks data at 11 MHz and the STM32F769NIH6 is running at 120 ...
Hi,I am working on a custom device, based on Murata CMWX1ZZABZ, running both Sigfox and LoRa.Regarding Sigfox, I would like to use my own Sigfox Credentials, acquired direclty from Sigfox (not from Murata). However, the only documented process I can...
I'm using an ST part that has 2 banks of flash memory. I've built a code image for the second bank and downloaded it through the debugger. I've changed the startup script to set the VTOR register to the value needed for the second bank, with the line...
Hello, I'm using the STM32746G Discovery Board to familiarize myself with the ST environment. Now I simply wanted to store a 32Bit value in the RAM, and had several problems with the Cube BSP drivers. I tested the functions with the following code: #...
