About STMF407xx I2S DMA circular buffer playback DMA interrupt inconsistency issue
The STM32F407XX chip is used in the project, and the audio codec chip WM8978 is connected through I2S. The voice data adopts 8000 sampling rate data format 16bit, two-channel. STM32 I2S unidirectionally writes audio PCM data, using cyclic DMA double ...
The values read by my ADC have not sense considering my RES setup (STM32H747).
I am using the VREFBUF as a reference for my ADC reading and I set it up to the max (2.5 V) and used the capacitor circuit described in AN5690 p.2 Fig. 2. The code used for my ADC and VREFBUF are described here : void VREFBUF_Init(void) { SET_BIT(R...
Resolved! How to include/find the source and header files for LL-Drivers?
Hi there, I have been using STM32G474, but if I look into the HAL driver folder structure I cannot find the files for LL-Drivers. I want to use LL functions in my code. Looking forward to your quick suggestions.BRs,Waled2G474RE, the documentation say...
Six SPI continuously monitoring
Hello, I am working on STM32H7 series controller, I have to continuously reading the data of dac through spi and vtg ,and send over an GUI application so every 50 microsecond I have read the values of 6 spi , so I have do the calculation in stm32 or ...
Is the STM32F43x underlying chinas import/export regulations?
Is the STM32F43x under any import/export regulations, if you want to export a product with F43x to china? Because for example china has theyre import and export list for crypto devices. Or in regard of Wassenaar Arrangement? Even tho our product does...
How do I create an Interrupt for UART_FLAG_TXE?
I have a STM32L081KZT and I am using the LPUART.I want to create my own Interrupt (handler) based on UART_FLAG_TXE. So basically a function that gets called whenever the UART_FLAG_TXE bit is set.In the GCC compiler manual I have found this:void f () ...
Problem with configuring/transferring an SPI with DMA (And CRC).
I can't get a data transfer over the SPI bus with my currently implemented code. I can see the CLK and CS but there is no output via MISO (only zeros are probably transferred). If I execute a transmission manually via "LL_SPI_TransmitData16", I can s...
