Hi everyone,I am encountering issues in sdcard initialization on my custom board.I am getting SDMMC_FLAG_CTIMEOUT error in SD_PowerON once the first CMD8: SEND_IF_COND is sent.Looking at signals and comparing with an identical custom board, you can s...
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

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...
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,...
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...
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...
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...
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...
