Hi,I'm trying to get a timer with external clock (ETR2) to trigger a DMA transfer from GPIO to memory on a STM32H745 with no luck.I'm using cubeMX to generate the code below.The timer seems working. TIM2_IRQHandler is triggered periodically.However n...
STM32L451RE - How to detect a Wakeup event in shutdown mode?Hi,I connected a Accelerometer interrupt on Wakeup Pin 2. In Standby mode "HAL_PWR_EnterSTANDBYMode();" I can wakeup MCU by moving Accelerometer.After that, the flags "PWR_FLAG_WUF2" and "PW...
Hi,I am setting up my STM32F405RG with 3 analog inputs on ADC with DMA.The problem I'm having is that the ADC buffer is being filled in the wrong order:For example, I have channel 11, 12 and 13, with ranks 1, 2 and 3 respectively, so I presume the AD...
Hi,I am using stm32L431, in the documentation says that when using LPTIM pulse counter the 5 first pulses is lost, after this the counter works fine. But in my project this situation is not acceptable, because in some cases I use less than 5 pulses.I...
We are using the STM32F746 in combination with an exernal SD-RAM.The clock rate for the RAM is set to a frequency of 96 MHz.At radiated emission measurement we are above the limit line at 192MHz (double RAM clock)Is there a possibility to activate ji...
Hello,I'm using STM32F767 custom target board with J Link debugger, everything was working fine since last 2 months till today morning, while debugging my existing project following pop up message came up. instead of selecting options right way, I've...
Hi All,I am able to generate OPM pulses using Timer 1 of L4R5ZI MCU.Problem is - I want pulse train having 20 pulses first time. Once they are generated, after ~5ms delay, I want another pulse train having 5 pulses. This is not working. OC1 pin has p...
Hi,I am trying to check IWDG functionality on Nucleo-L4R5ZI board.Referring to the example code available for NUCLEO-L496ZG, i created new project for L4R5ZI nucleo. I was trying to go step by step in debug mode. When the debugger is inside HAL_IWDG_...
Hi all,First post on here so apologies if I make some errors in my question format/clarity.I am doing some testing using the SPI HAL library attempting to communicate with another chip, everything works as expected and I can successfully send bytes a...
I need to be able to toggle between 3V and 5V per pin for about 40pins. i.e command output_high_3V would get 3V etc. I am not sure the best way to go about it since STM32 are only 3V3 pins. I was thinking of using GPIO Expanders, or some transisto...
