I have problems detecting a falling edge external interrupt. I can see with the tester the signal changes from 3.2v to 0v so its produced but the the interrupt is not generated. Could the 3.2v instead of 3.3v the problem?Signal is oscillating 3.19-3....
I read in the reference manual that the STM32H750 has a 32-byte fifo. FTHRES is the FIFO buffer and FLEVEL indicates how many values are stored in the FIFO buffer. The reference manual also explains that after the FIFO is full the QSPI peripheral t...

I have configured 2 UARTS both are configured to using HAL_UARTEx_ReceiveToIdle_DMA.My init functions:HAL_UARTEx_ReceiveToIdle_DMA(&huart3,aRxBuffer, RXBUFFERSIZE); __HAL_DMA_DISABLE_IT(&hdma_usart3_rx,DMA_IT_HT); HAL_UARTEx_ReceiveToId...
Hello,I am currently working on my end of year project. I first realized my project under a development kit then now I realize the PCB.I am currently facing a problem. I have an STM32L073RZ which I must supply. As a power supply, I have a Li-SOCl2 ac...
When using an EXTI input to trigger a DMA request, there is only the possibility to trigger on falling or rising edged of the input. But my peripheral has only an output which is active when data are ready for read or write. This output is static and...
Hi all,I have a CAN 2.0 network up and running with a F407 and some F103. I added a board with a G0B (fdcan). I couldn't get my hands on a FDCAN-tranceiver. I tried to get it working in classic mode (from repository example) with a CAN2.0 tranceiver....
I have to implement a lifetime counter with microseconds granularity using a STM32L432KC to control an AFBR-S50 sensor. The timer has to count "forever" and this board only has 1 32bit timer, so this timer is for the seconds, i think is the only way...
I would like to build an application on an STM32 microcontroller (the one integrated in the NUCLEO-L432KC) that allows to transmit a message of 192 bytes or more if possible on CAN BUS.At first, I was thinking of a mechanism that in the transmission ...
Hi everyone!In my project, I use TIM2, TIM3, TIM4, TIM5, in each Timer module I choose PWM Input on CH1, and PWM Generation on CH3 function. My goal is to generate PWM pulse at channel 3 and feed back to PWM Input on CH1 to measure Duty cycle and fre...
