G.722 vocoder
Hello,I've seen the AN4229-how-to-implement-a-vocoder-solution note, which talks about support for G.711 and G.726. Does anyone know if anything is available specifically for G.722?Thanks

Resolved! Micro Trace Buffer (MTB) on STM32U5 devices?
Dear STM CommunityIn order to ease our debugging, I would like to make use of the Micro Trace Buffer which seems to be integrated in the Cortex M33 Core (e.g. stated by STM here: https://www.st.com/content/st_com/en/arm-32-bit-microcontrollers/arm-co...
Resolved! iwdg is not working while usb device is running.
Hi,My MCU us stm32f401rct6.This MCU has three UART and all UART are using for service. No console UART port :(So, I make a USB CDC device to use console port.But, iwdg is not working. When I use UART console port, while(1); occur watchdog reset. But,...
SPI1 with DMA Overflow Issue
I have SPI1 setup as Receive Only Slave with DMA enabled. I send 10 bytes from SPI2 ( to simulate a full duplex master uC ) and it works well the first time I transmit 10 bytes. When I transmit 10 bytes a second time, SPI1's overflow flag gets set...
Resolved! Understanding MPU config for FMC LCD on STM32H7
Hi,I'm currently trying to understand the recommended MPU config (when settings up an 8 bit LCD connected via the FMC on an STM32H742. Everything is currently working, but I haven't been able to wrap my head around why configuring the MPU regions wit...
Resolved! Wondering different port GPIO Power Consumption matter?
Hi everyone.I am recently working on stm32 chip and found a page show the power consumptionseems GPIO port C and F can save half the power than A and Bshould i always consider to use gpio port C and F ?or the consumption is too little that we don't n...
Copyright notice in main.c generated by Cube.
Posted on October 11, 2016 at 08:27Since the programmers are supposed to munge main.c into their own project, Cube generated code being just a starting point, why would ST put in a copyright notice that takes ownership of the code?This is the transi...
Strange behaviour when reading flash in FreeRTOS environment
Dear communityI have a strange behaviour, when I want to read the flash of an STM32U5A9 in a FreeRTOS task. I have a function, that programs incrementing numbers on a whole flash page of 8 KB (confirmed with J-Mem, that programming worked). If I want...
Resolved! STM32L562CE 48-pin 1.8V USB
Hello,As I understand from datasheet if you use 64, 81, 100, 132 or 144 pin package there is separated power supply domain for USB transceivers, i.e. VDDUSB which should be connected between 3.0-3.6V or connected to VDD if USB is not used.However, 48...
