Resolved! Problem with HAL_I2S_DMA_Receive()
I am using STM32f407VG Discovery for audio application. I am having a problem while using the I2S2 in Slave Receive mode using the HAL_I2S_DMA_Receive() for receiving 16-bit data on a 32-bit frame. I am able to get the Audio data correctly at times a...
STM32G070. In the code generated by the CubeMX, there is the colock source is selected for the TIM1/15, TIM1CLockSelection/TIM15CLockSelection. But in datasheet, the clock source is only TIMPCLK and no other source. I think this is the tool bug.

Programming alternatives of the STM32H750VB
Hello,I would like to ask a question further to my recent one about the Value Line STM32H750 3 weeks ago or so.The chip has 128KB Flash and 1MB RAM.Assume my program is bigger than 128k and I decide to use NOR Flash as a storage and to run from the ...
Just how powerful are STM32s?
I'm sure this is a pretty loaded question, especially considering that there are a range of them out there now, plus I'm sure it also varies based on application(s), im just curious because I am coming from an Arduino world (and going to school to g...
Parallel synchronous transmission using GPIO and DMA. Which chip to use to receive data under 20MHz?
I found the doc AN4666 and AN2548, but I could not come to a conclusion.I have the STM32F103C8T6, but when performing a sequence of 1000 readings, the average time was of 266us, approximately 3.759398 MHz.I would like to know which chip model should ...

Resolved! C++ program gets stuck at __libc_init_array in startup
Hi all, I have a C++ project running fine on the STM32H7 EVAL board that I need to port to an STM32H7 Nucleo board, because it closer resembles the final hardware I will be using. I generated a Nucleo project using CubeMX and added all the things I n...
stm32f7 SAI1B DMA2 stream 5 and 0 conflict with SDMMC2 stream 0 and 5 ????
Hi,stm32f7 SAI1B DMA2 stream 5 and 0 conflict with SDMMC2 stream 0 and 5 ????I need to record data to and playback from SDMMC2 with DMA to and from SAI1B.SDMMC2 uses both stream 0 and stream 5.DMA2_Stream5_IRQHandlerDMA2_Stream0_IRQHandlerThe periphe...
STM32L052K8U6 - Now I have a question - How much the internal clock is reliable ? Is that any option to use my external clock for UART 115200 baud rate communication.
I am planning to use STM32L052K8U6. With this Controller I am planning to use UART and ADC and digital IOs. Only LSE (low speed external clock) is there and I can only provide 32.768KHz. With this clock I can't generate 115K baud rate with LSE alone,...
