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'm running an STM32F373 with 8Mhz osc and enabled PLL in the clock config to get 24Mhz on the timer buses.I setup TIM2 to TIM_IT_UPDATE interrupt at 4Hz. I send a one time 10ms pulse to an output pin each time TIM2 interrupts. ( I have a speaker b...
hello.I am implementing I2C slave with STM32F103C8T.I2C is operated by a external master.It must support Rx and Tx from 1 to 16 bits as shown below. Purpose: To implement the following functions.- Operates as I2C slave- Write 1Byte address > Repeated...
I am using PB6 as a GPIO input with a pull-up for monitoring a switch to ground. It works properly when not debugging but has some kind of signal on it when debugging that prevents proper operation. Note: I am using the STLINK-V3SET debugger.Is the...
Hello,I ran the STM32CubeU5\Projects\NUCLEO-U575ZI-Q\Examples_LL\RTC\RTC_ExitStandbyWithWakeUpTimer_Init application, which worked as described in its README.md. After changing the low power mode from STANDBY to STOP0, the RTC interrupt no longer fir...
Hi,I am using a STM32H743BIT6., I am trying to access two SDRAM part-number(IS42S16320D-7TL)problem:both the DRAMS are wring the same data at the same time, so instead of having access to a 32 bit i am getting access to 16bithelp will be apricatedTh...
i get `FR_NOT_READY`, `HAL_SD_ERROR_REQUEST_NOT_APPLICABLE` errors ./* If requested card supports wide bus operation */if((scr[1U] & SDMMC_WIDE_BUS_SUPPORT) != SDMMC_ALLZERO){//...return HAL_SD_return HAL_SD_ERROR_REQUEST_NOT_APPLICABLE; }ERROR_NONE...
Dear communityI develop a 'robot" with odometrie.Each geared DC motor have a rotary magnetic encoder for speed regulation.My question is about avoid count overload.I use a timer for read encoder count. Each interrupt, i print the value.My aim is avoi...
Hi,I am implementing micro-sd card with STM32H573RI using SDMMC1 interface. I am using HSE clock with input frequency 25MHz and the system clock is running at 250 MHz. SDMMC1 clock mux is sourced by PLL1Q(25MHz).All the SD card initial commands in th...
Hi amazing community. I would like to write some data in the flash memory of the following mcu STM32F103I know there are some dedicated pages for such purpose.How can I guarantee or understand that the future code that i will develop and it will be s...
