Posted on June 29, 2018 at 07:30Hi, I'm trying to use SAI_DATASIZE_24; with the Audio_playback_and_record application demo for the STM32f769i_Discovery.The demo uses DMA to copy data from the SAIx to the recorder buffer in 16bit.I tried changing the...
I am looking for maximum timer resolution supported in STM32U5 series MCU's.Basically whether I can configure or use hardware timer as 100us.Any input or documentation on this would be a great help.Thanks!!
Hello,I am looking for help. I am using stm32L0. The problem is as follows:ST goes in stop mode for example 5 seconds. After 2 second some interrupt wakes the ST. Then I want go in stop mode for the remaining time which in this case is 3 seconds. Is ...
Hi guys, I'm a mechatronics student learning the basics of STM32s in my own time through the excellent series of guides by Vivonomicon. I'm currently learning interrupts, but my program seems to trigger a SIGTRAP fail when the interrupt fire.The code...
I have some old program to migrate to stm32h7. the old program is written by 16 bit mcu. so it is easy to implement union structure and easy to copy structure from memory to another; however, in stm32h7, this is 32 bit mcu, so memory size is 32 bit, ...
I try to recreate this tutorial:https://deepbluembedded.com/stm32-input-capture-frequency-measurement-example-timer-input-capture-mode/I use STM32H747I-DISCO board instead. It's configured to generate 25kHz test signal. Main clock is set to 400MHz, t...
Why I get \0 at the end of the transmission?I imaging the \0 is a NUL termination character but I have seen from the terminal that sometimes is not received or arrives with a big delay.Could somebody tell me anything about it?Thanks in advance.
I am trying to make SPI6 work with BDMA I see that transfer completion flag set in BMA ISR but SPI registers i don't see EOT bit set. I don't see any data coming from MOSI line of SPI6. Please help me know what is going wrong. There is no error set i...
Hi evryone,I try to find a way to read a DMA memory buffer n consecutive times but the issue is that there is a normal mode (1 time) and a circular mode (unlimited time)I would like to find a way to end the circular mode when I decide, for example to...
