I have enabled DMA for usart2 in pins PD5 and PD6 and I have attached my main file. I have tried uart transfer by polling mode and interrupt mode both are working fine. But when I try for DMA mode the data is not transferring .I don't know where I ha...
I am using an STM32 MCU. When I use the HAL_Delay function with a parameter of 1000 for example, I see that the delay is shorter than it should be. I have checked that HAL_IncTick(), but it works correctly and it is placed inside the SysTick_Handler....

Hi, I'm using STM32CubeIDE to develop firmware for a small appliance (using STM32F303) in C++, but I'm in troubles related to the build process, caused by generated files like stm32fxx_hal_mps.c including C++ headers, while being compiled with gcc.Wh...
Hello, everyone,I test CANFD a long time. And I found that some Bit Rate doesn't work together. For example, I use CANFD Mode, set to 1M + 5M. It work well. But same parameter at Data Bit Rate，I change to 500k + 5M， or 250k + 5M， it can't work. It al...
Hi, I would like to ask, I have a SPI setup Full duplex which my STM32f302R8 nucleo board as a master and arduino UNO as my slave.I send a data 0x0C from master to slave. During transmission, I know that the slave will return a dummy data back to the...

I am trying to take a microphone sample every 62.5 microseconds (16,000Hz) which is the standard rate for audio files. The problem i have found is that HAL_SAI_Receive_DMA() returns HAL_BUSY for some samples. So we dont receive the required 16,000 sa...
