we have a STM32L07CBT6 and we want to disable the VREFINT with following HAL functionsHAL_PWREx_EnableUltraLowPower()HAL_PWREx_EnableFastWakeUp()but still want to use the BOR. Therefore I checked the section of VREFINT (6.2.4) and BOR (6.2.2) in the ...
Hi everyone, i'm quite new with the stm. Currently im using the stm32f411 discoveryboard and trying to get the pulse width in order to measure range, i did try to search for solution and find out about input capture method but the code is on sw4stm32...
Hi,I have a custom board with an STM32H745 which doesn't boot / I can't connect to.I've noticed that three of the gnd pins are not connected K15, L15, M15, would this cause the problem?The design is using an external 1.2V supply which is fine. 3.3V i...
I am developing a device that simultaneously logs two CAN lines using the STM32H743.I saw "Wrong data may be read from Message RAM by the CPU when using two FDCANs" in STM32H743 Errata document.I need a detailed explanation of the above Errata.I am t...
HelloI'm using the "en.fp-sns-allmems2", which send data from sensor with a ultra-low power consumption. I'm traying to increase the time in which the sensor is in shut down mode.I think that I've to change the value of the variable SHUT_DOWN_TIME_O...
I know that DMA interrupt don't need rising/falling edge trigger because DMA interrupt is an internal signal.Except this result is that any additional result why DMA interrupt don't need rising/ falling edge trigger?
Dear Experts,Can I configure the DMA2 to do say 3 repeats read on GPIOx_IDR by a single DMA request? I do not want to have array of bytes instead I would like to write into a single variable and overriding it with the latest value.I have set the MINC...
Hi every one.I want to read the value of a potentiometer connected to the pinA1, and if the read value is more than 2000, one of the LEDs, otherwise the second LED, will be on.Can anybody please help me? what is wrong with my code? I don't have too m...
Hello all, I want to count pulses with TIMER 1, because he has the fastest counting frequency. I was able to count pulses with TIMER 2 but something in my code is missing to make it work for Timer 1: (I also checked the reference manual ...)Maybe som...
This problem just popped up for me. I'm not sure if I'm doing anything wrong, but timers other than timer 1 don't have functioning PWM. I configured the timers the exact same (aside from ignoring timer 1's special features,) making sure to include HA...
