I have recently developed a USB Compoite (HID Keyborad & Audio Speaker) device using the STM32G491.I have been able to have it recognized as a Composite Device in the Windows 11 Device Manager, and I have been able to input keys and play PC sound fro...
Dear STM Community,I've configured the SAI on my Nucleo-G474RE board by setting the protocol to "I2S Standard" and data size to 24 bits to communicate with an external 24 bit ADC. Further, the SAI works together with the DMA to fill the buffers. Here...
Hello,I am trying to read sample from a AD7768 using a STM32F767. The data is feed to the SAI peripheral at 8Mhz. I used this code https://github.com/pavel-demin/stm32f7-discovery-usb-headset/blob/master/Drivers/BSP/STM32746G-Discovery/stm32746g_disc...
I'm running tx and rx of SAI_I2S by double buffered DMA.I expect on double buffered DMA to change Current Target or CT register bit state to change at each Transfer Complete or TC. But on tx DMA stream it changes CT, one sample before TC. Why? But in...
Hello,In my project I need to do two 10kHz feedback loops, and I want to make as much in hardware, so I don't have to waste time communicating with dual channel DAC.So my bright idea is to use a fast 200ksps 24b DAC for generating analog setpoints. I...
Hi Team,I am using a the SAI Peripheral from the STM32L5 family to read data from a master device. I am employing the DMA peripheral to read the data from SAI. I have a buffer of 32kb and I am using the STM board as a slave device. I am using the HAL...
Hi,Having STM32F723 DISCO with simple play/record example. Need to process sound by 20ms periods, so I've calculated PCM buffer size as :```#define AUDIO_CHANNELS 2#define AUDIO_PCM_BIT_RESOLUTION 16#define AUDIO_SAMPLE_LENGTH_MS 20#de...
I've written a code to trigger(toggle) GPIO_C1 by ADC_TC interrupt. And the GPIO_C13 by MDMA through SAItx_TC request.I've programmed to both GPIO toggle together in-phase. But GPIO in-phase behaviour can be achieved in first time I program in MCU wi...
Hi everyone,I am trying to get the SAI1 periperhal configured in I2S Standard mode going on the STM32H753ZI. During my testing sessions I found that my master clock is so far off it doesnt make sense. Based on the figure 652 within the TRM, it shows ...
I am working on the STM32F769 series microcontroller in my project. I am using SAI interface of the mcu. And of course I also use DMA of SAI interface . I adjusted the DMA(DMA2 Stream 1) as listed below in the application :DMA Request Settings : Mode...
