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...
There is MCO that supports PLLCLK, HSI, HSE, SYSCLK but not LSE with 32.768khz. How can I produce this frequency for FCLK pin of Max30003 sensor? Do I need use Timer? If yes could you send me some examples how to do it properly?
There are conflicting things written in STM32 documentation regarding SRAM retention during Standby mode with SRM32 G0 MCU.For example, in RM0454 G0 Reference Manual it states two different things 1 paragraph apart .The UM2319 G0 HAL/LL Manual has a ...
Hi all,im trying to bring a timer interrupt to work. In the first step I want to create an LED blinky.For that I followed the instructions from the Knowledge base example (How to generate a one second interrupt using an STM32 Timer). The only differe...
hello i am working with i2c i used register for coding i2c but when i configure AFRH register i cant upload my code to my board i have target not responding error then i tried hal library but nothing changed
Hi, I am trying to detect whether a reset event was caused by power on rather than any other reset such as a button reset or a software reset. I attempted to use if (__HAL_RCC_GET_FLAG(RCC_FLAG_PORRST) != RESET)but the compiler reports that PORRST ...
i see somewere that the way to erase the flash is to do this instructions.FLASH_EraseInitTypeDef EraseInitStruct;EraseInitStruct.TypeErase = FLASH_TYPEERASE_SECTORS; EraseInitStruct.VoltageRange = FLASH_VOLTAGE_RANGE_3;EraseInitStruct.Banks = FLASH_B...
The RM0440 ch. 28.3.18 rev7 mentions on page 1128:> An interrupt is generated if the BIE bit in the TIMx_DIER register is set. A DMA request can be sent if the BDE bit in the TIMx_DIER register is set.Unfortunately, the DIER register does not contain...
Hello. I've noticed that DCMI/PSSI code does not provide this functionality, but it is very handy when using DMA in circular mode (ADC, frame buffer pumping to other interfaces, etc.). I've tested DCMI+DMA circular mode on F4 and PSSI+DMA circular mo...
Some ARM/STM32H7 CPUs have a problem with single stepping through code. Which CPUs didn't have this problem? I have planned to use STM32H750 because it is now somewhat available, but I could swap.
