Hello,I'm trying to implement a UART DMA data transfer in STM32F429. I face the following problem.I'm using custom-made Python to receive and transmit data over the serial port. I am sending an unknown number of bytes from my computer to MCU. So, I'm...
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...
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
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...
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...
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?
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 ...
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...
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 ...
