Hi everyone, I'm using an STM32F0 Nucleo board. I've been trying to implement an input capture function that tries to measure the frequency of an input PWM signal. I basically record a timer count when I get the first rising edge and the second risin...
Hi,With H7 the mapping is simple, we can use multiple streams at the same time, one channel per stream.But with L4 , it seems to be more complex, especially usage of "channel" terminology:For L4, Is it that we can use multiple channels ? Thanks,ranra...
I am trying to set up the ADC to continuously scan a few channels in the background and store them in an array automatically using the DMA. I have been trying a vast number of things to get this work. If i don't set the the ADC to run in CONT then t...
I am building a radar back end wherein I have to process 4 ADC channels coming in from radar front end and want to do processing on each channel and want to store the adc values in the buffer so that I can do DSP on it.
i am having STM32F0103 discovery board and STM32F746ZG Nucleo. i want to check maximum speed on which i can toggle GPIO. When i select 48 MHz in STM32F0 i am getting maximum 1.25 uSec which is around 800 KHz Max.in case of STM32F7 i am running at 216...
Hello,I tried to store data to flash on a STM32H742 (running at 480MHz) and I have some timing issues. Meanwhile I found myself a workaround that I also want to share here. Still I would like to ask some questions to better understand whats going on,...
Hi,I guess this question has been asked over and over, i have tried my best to read what i can to understand sleep mode.However I am having difficulty as i am not using the HAL library that everyone refers to.I use a program called Flowcode, basicall...
Hi,We developed a custom board using the STM32F479NI MCU (using the Rev A).We are using a SEGGER J-Link JTAG adapter to flash and debug our MCUs.We are able to detect the MCU and to flash it using the J-Link softwares.But when trying to debug the MCU...
About fault exceptions, as I can understand user level trying to access privileged level memory will result in Memory Management Fault... but in Table 5.1 from Joseph Yiu's Guide to ARM Corten-M3 2nd edition page 83, it says Why that results in Bus f...
Hello guys, I hope you can help me. I'm using a STM32F439 board and the following setup:In my application FreeRTOS with FatFS is running. For reading and writing blocks from my eMMC I use a DMA transfer. The problem occurs very seldom (in an 40 MB fi...
