Some issue to entered and resume from low power mode by using CAN interrupt.
Hi All,I am new in development of controller run in low power mode and resume, I used the STM32F072RBT6 microcontroller. In my code CAN Peripheral with extended data frame( 1 Byte data) format and three timers are used.Now, The requirement is when...
STM32G071C8T6 and USART3
Hi All,I don't managed to send char on USART3 with the attached project.I was wondering if someone had already detected issue in using USART3 Thanks in advance
Inconsistent CK_TIM18.. usage in reference manual
In the reference manual STM32H7 (version July 2018) in chapter 37.1 - figure 343 for the clock source it says "CK_TIM18 from RCC".Problem: If I look for "CK_TIM18" in the complete manual, this name appears ONLY ONE TIME, here in this chapter 37.1 fig...
STM32_PVD_need to set the reference Voltage
Hi i am using stm32H750VB as the IC for my project.I need to detect sudden power shutdown .I.e., i need to use PVD mode for detecting the sudden drop in voltage and save the EEPROM Contents.I need to use PVD using external analog voltage PIN RB7. But...
how to count pulses per interval
I want to count the number of pulses that occur in an interval controlled by a timer. I want to trigger the timer and the counter simultaneously. How can I do that?
Resolved! STM32G431 Can't get DMA interrupts to trigger
Hi All,I please need your help as I have been stuck longer then I care to admit,I have a STM32G431 48-pin device which I am using TIM8 for input capture with DMA. I have an external input (PC6) for Ch1 input and am using a software trigger for Ch3.I ...
Porting OpenThread to STM32F4
I've just started a personal project to communicate between different embedded devices using STM32F401RE via OpenThread. I would like to know if it is possible to use F401 processors and its peripherals combined to a separate radio such as nrf24l01 t...
How to stop writing in memory where DMA can't access
Hi guys, I'm having this issue where I kept getting a Transfer Error when setting up a DMA.One of the replies I got is that DMA1 can't reach the memory area of DTCM, which would explain why it can't transfer the context from the buffer into the peri ...
STM32L4R5 Quadrature Encoder Hardware Connection
I'm trying to connect a quadrature encoder to my board using STM32L4R5. From what I understand, I should connect the A and B to TIM2, TIM3, TIM4 or TIM5. If I have 2 encoders, can I connect all 4 A and B signals from both encoders to the same TIM? Li...
