Can I write to a UART Data Register if the RXNE bit is set(data has been received in the RDR but not read yet) ?

I want to use the WM8994 on the STM32F769-DISCO for 24 bit acquisition on the Line In connector. Unfortunately the BSP code is fixed at 16 bit. :-(

Has anyone done the changes necessary to switch up to 24/32 bit acquisition. It seems like its just AIF1_Control[6,5] on the WM8994 but the SAI is a complex beast and I'm not having a lot of luck. Any pointers would be greatly appreciated.

DMA HALFWORD and SAI_DATASIZE_24;

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...

Getting elapsed time after stop mode

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 ...

union type structure memory

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'm beginner in STM32(f303re CUBE IDE) and anybody know maybe how do the implementation for sensor fs-ir02. Probably it's simple but I have no idea. How to do this with USART2 on NVIC and by simple GPIO? When is another simple way, please show me :) thx

TIM CC1 register is always zero in input capture mode.

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...
