Hi all,I reach out to you all to give some pointers or advice for me where to look into to solve this mystery.I set up my Nuc-STM32F439ZI eval board i2s peripheral to play my audio sine wav file.I used Audacity to generate 13KHz sine wave audio file ...

I am using STMCubeIDE version 1.7.0 and I saw the generate code for the initializationhas different orders when I configured my ADC with DMASometime the code was generate with ADC init before the DMA init MX_ADC1_Init(); MX_ADC3_Init(); MX_DMA_Init()...

Would anyone knows why the STM32F7xxin stm32f7xx_hal_i2c.h structure I2C_HandleTypeDef doesn't have __IO uint32_t Devaddress; /*!< I2C Target device address */ __IO uint32_t Memaddress; /*!< I2C Target memory address */ ...

Thank you both @waclawek.jan and @MM..1 for your pointers.I got the correct sine wave output as my source with the same frequency. It is all from I2S needs to have the sample buffer = 2x my source sample buffer.So for anyone interested the way to c...

Thank you both @waclawek.jan and @MM..1 for your explanation about I2S implementation. Please spare couple minutes with me about this issue.I think when I tried to provide completely information some how it made the problem that I tried to trouble s...

@waclawek.jan wrote:> int16_t buff[BUFF_SIZE]; // output bufferAnd you then play back from this buffer?Yes, from the prepare buffer buff, you can just call the function the HAL_I2S_Transmit_DMA(&hi2s2, buff, BUFF_SIZE) once only if you already set up...

> I2S generated correct signal, bit clock, frame rate,How did you verify that?I used logic analyzer to check the I2S signal from STM32's I2S pins, bit clock, frame, data all decoded from the array data.>data valid meaning my I2S signals matching with...

@Arrvinddd do you have any luck to source the needed display? I got in to the same situation and have a hard time to find the 6", 2 lanes MIPI-DSI display to use with my STM32H747

STM32F439 I2S double the audio frequency

STM32WB5MMGHx custom app couldn't go back to OTA Loader App

USB Full Speed MSC using uSD (SMMC2) and FatFs took so long to enumerate

Is there a way to configure the order of the auto generated code?
