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'm using the STM32746 Discovery board and some example code - the "QSPI_ReadWrite_IT" example - but the QSPI interrupts are not working correctly. Specifically the Status match interrupt never fires and the example code gets stuck. I've ported ov...
Hi all, I'm using a stm32f10x connected to a CANalyzer in order to verify the integrity of the CAN bus. The implemented process is simple, I have transmitted a CAN trace ( 11 bit ID + 8 bytes of DATA ) to the CANalyzer and it responses automatically ...
Hello everyone,I'm using USART3 on F746, but only RX/TX pins which are mapped to pins PD8/PD9.Besides that, I want to configure general output to pins PD10/PD11 (to control LEDs), but they don't work when I try to control them. I looked up the AF map...
Hello,currently I'm trying to use the LPUART of the MCU using the LL drivers but I encountered an annoying issue.In short:LPUART1_TX = PB6LPUART1_RX = PB7-> Tx not working, pin always low; Rx fineLPUART1_TX = PA1LPUART1_RX = PB7-> Everything working ...
Hi!I'm using mpu6050 and Nucleo-f103RB without MXCUBEi got problem with I2C communication.LED is blink in infinity../* Wait until SB flag is set */ if(I2C_WaitOnFlagUntilTimeout(hi2c, I2C_FLAG_SB, RESET, Timeout, tickstart) != HAL_OK) { return...
I set a timer to count 500us ticksTIM_InitStruct.Prescaler = (uint16_t)40000-1; //SYSCLK = 80Mhz – 80Mhz/40000 = 500us TIM_InitStruct.CounterMode = LL_TIM_COUNTERMODE_UP; TIM_InitStruct.Autoreload = 0xFFFFFFFF; //TIM2 – 32-bit c...
I'm searching for a stm32 with 8 uarts for io-link. But there is no way I can search for peripherals. So any suggestions, preferably in LQFP-48 or something similar small.Thanks.
Hello!I have a trouble with Timout delay in SDMMC_GetCmdResp1. I invoke HAL_SD_Init from freertos task. Now SD card isn't connected to board. Timout deleay take approximately 30 seconds, but Timout is 5000 ms.static uint32_t SDMMC_GetCmdResp1(SDMMC_T...
Hi,I'm trying to replicate the Hands-on Flash memory Technical training for the STM32L4 (https://www.youtube.com/watch?v=ZMtsR0nZjt4) but i'm having some issues when changing the BOR level and specially in the debugging. The instruction "HAL_FLASH_...
