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 dont understand why this is a option for the mux clock selector. css is a great feature so i didnt find reasons to not enabling.In which cases i should not enable it?
We are using "STM32G473VET6" in one of our application requiring 7 pins from different ports to be mapped as external interrupt (EXTI) vector. But as per reference manual document "RM0440" section 9.3.8, "All ports have external interrupt capability....
TIM1 is configured for complimentary PWM for three phase motor control.PWM switching frequency is 4khz i.e. 250us, but i am finding that PWM time is getting varied from 244us to 248us. sometimes 252us.Is it some calibration issue or what? Can anyone ...
HiFigure 120 in the reference manual RM0008 shows the control circuit in normal mode. It shows an update event using the Update Generation bit (UG). See attached figure.I am curious about the CNT_INIT bit, which is a pulse one clock cycle after the U...
Hi,I have a board containing an STM32F415RG and another board containing an MCU from another manufacturer. Both boards are supposed to communicate with each other using RS-232 transceivers. The communication is running at 9600 baud and working well f...
I'm using STM32l152 and use TIM5_Ch2 for generate pwm .My target frquency pwm is 2.85 KHz .I using these parameter:clock frequency = 32MHz htim5.Init.Prescaler = 6; htim5.Init.Period = 100; I measured pwm on oscilloscope and I measure 2.85KHz with 5...
Hello, I'm trying to understand the peripheral to peripheral transfers. I'm pretty sure my setup is correct but it's not working and I don't think I understand enough to know what to look for to troubleshoot. For my test I simply have uart1 rx connec...
HiI wish to use an external clock into PH0 from an oscillator module already present in my design.Does this mean PH1 becomes a spare pin?ThanksAndy.
Hi to all,I need to send on every TIM interrupt a packet stream to SPI1. I can't use the HAL_SPI_Transmit(...) because it is blocking....so I need to use the DMA but not in circular mode.I can not use the synchronization of DMA with lptim using DMAMU...
