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...
I'm really struggling with this problem. This is my first time trying to do anything low power, so please forgive any noob mistakes. All I'm trying to do is get the hang of a simple low power program so I can apply it to a larger one. My code is here...
I have an application where I must be able to update the code remotely through the CAN2 link and the embedded bootloader. This worked fine using the mass erase function, but now I need to erase sectors individually. The ap note AN3154 poorly describe...
Hello This is my first time using STM32 MCU on my own PCB. I know that I have to take many things into consideration. Please help me if I am missing somethingI have wired up all VDD/VSS/VDDA/VSSA/VUSB with bypass caps as close as I couldI have used e...
