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...
Hello eveyone,In my code i try to set the BOR level with the following function:/** * Set proper BOR level. */ void setBorLevel(void) { FLASH_OBProgramInitTypeDef optionBytesInit = {0U}; bool_t isBorLevelConfigured; uint32_t borLevel = ...
Hello!I'm working on a custom board with an stm32L051 and the HSI16 crystal. I'm setting the clock registers, Flash, PWR and then I try to enable the clock for TIM21. as you can see in the code I set the bit but the computer "doesn't listen"(I am loo...
I want to perform a timer interrupt using the output comparison mode.When the frequency is set to 2000Hz, ARR : 20, CCR1 : 25, I think that interrupt does not occur because ARR <CCR1, but interrupt occurs. Why do interrupts occur?
Hello,I need some examples to learn how to configure and use the touchscreen on STM32H747I-DISCO board.Could you provide it or direct me to the resources which contain such an example, please.Thanks,Best regards
we have experience checksum change ( or data corruption ) anomaly in various stage of production assembly process, this anomaly occurs 1) when we power up the system, we got checksum error, does it mean that the data from default factory setting wa...
I'm using STM32CubeMX and HAL functions.I've gotten interrupt capture working for Timer 3 Channel 3. However, my input frequency is low and the 16-bit capture value is overflowing multiple times. I've solved this many times in the past with a diffe...
I'm reading data from an FPGA over QSPI. I'm attempting to read 256 bytes at a time. However, when I read the data the QSPI clock decides to take a long pause before continuing. I get an initial burst of 74 clock pulses, then 56 bursts of 8 clock pul...
Hello! Im receiving data by UART with DMA and now I wonder, how is HAL_UARTEx_RxEventCallback is ejecuted?Because I'm receiving and saving chunks of data in a buffer, then adding a header and a tail in this buffer to send it by USB, but I realized th...
