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...
Posted on January 24, 2017 at 18:54I am building a peripheral device that will use an STM32 microcontroller. This peripheral device will communicate with a master/supervisory device over a CAN interface. We have tentatively chosen the STM32F091CC ...

Posted on October 31, 2016 at 12:13 Dear all ST staff, I found a small bug in CubeF7 v1.5.1. Bug found at preprocessor macro definition of ''FMC_SDCMR_MODE_2'' at stm32f7 register definition files(stm32f745xx.h, stm32f746xx.h, stm32f756xx.h...
Posted on January 25, 2017 at 11:07Hi,I try to implement a timer with interrupt routine, but it always hangs after the timer is activated. This can be seen if I use the debugger over SWD: when I execute the next command after TIM_Cmd(TIM2, ENABLE); ...
Posted on January 23, 2017 at 18:27Hello,e.g. RM0377 lists the PWR_CR_LPDS bit unconditional for all L0X1 devices. * @version V1.7.1 headers define PWR_CR_LPDS only for L011 and L021. Is this right?#stm32l0
Posted on January 24, 2017 at 11:54Hi allI'd like to use UART2 to receive data, but It seemed to be failed, only could transmitted data.I used the same codes in UART1, everything is fine,So I think HW and SW parts are fine except UART2.I had not con...
Posted on January 24, 2017 at 15:09I have looked at PM0214 Programming manual for STM32F4 series for functions like GPIO_Write() and GPIO_ToggleBits() but they don't seem to be there. Is there a document that describes peripheral functions or does o...
Posted on January 24, 2017 at 15:27Hi allI'd like to use UART to receive soe fixed length datas, ex.'1234567890'.uint8_t buff[10]; hal_uart_receive_it(&huart, buff, 10); or hal_uart_receive_dma(&huart, buff, 10);How should I do and then make sure th...
Posted on January 24, 2017 at 14:39Hi,I'm using latest version of Cube (download 20.01). I'm trying to read ADC-values from SPI with DMA. Read is activated on ADC-dataready.#define ADC_BLOCK_SIZE 24uint8_t tempBuf[ADC_BLOCK_SIZE ];// This interrupt ...
Posted on January 23, 2017 at 18:35As the title says, can the analog watchdog high and low thresholds on F4xx be reconfigured while the ADC is running?I vaguely recall reading somewhere that it could be changed dynamically at any time but can't for ...
