I could cry... ("rrrr", the more I dive into latest STM MCUs - the more I get frustrated - LOL)The datasheet for STM32U5A5, LQFP64 package, tells me: there are PB15 as SAI2_SD_A and also PC12 as SAI2_SD_B.But the CubeMX does not let me configure thes...
Hi!I am still playing with the SAI of my STM32F446RE. It has one SAI (SAI1) which has two blocks, A and B.The idea is to use the two blocks synchronously in TDM mode to transmit in total 8 slots, 4 slots for each block.I can get it to work fine, thou...
Hello dear community,I’m working on a USB sound interface, using a STM32F7 and an external DAC chip offering 8 stereo output channels.Most of the DAC are offering multiple serial data inputs ports. For example, the Analog Device ADAU1966A is offering...
I am trying to receive audio data from an I2S microphone (https://www.adafruit.com/product/3421) using my STM32L476RG board and its Serial Audio Interface (SAI). I'm using cubeIDE and I have the SAI set up as in the pictures below, however I am not s...
Does anybody have an example code how to use SAI in STM32U5A5 as PDM interface?I use STM32U5A5, with LQFP64 package. So, I understand from datasheet: the SAI (I have just SAI1 available om pins), supports PDM interface (for MEMS MICs). My package has...
Hi, I want to create a timer with retriggerable pulse of specified length. Now I know timer can do it, but there is an issue with one pulse retriggerable mode that needs to be from outside trigger otherwise it dont work. My application is specific an...
Hi all,I am using the SAI peripheral on the STM32H753 and I have it set-up as follows:SAI2A - Master TX, asynchronousSAI2B - Slave RX, synchronous with sub-block ASAI3A - Slave TX, synchronous with SAI2SAI3B - Slave RX, synchronous with SAI2(SAI2 SYN...
In the STM32H7 ref manual (RM0433 - Section 51.4.4), the following is said about configuring an SAI block in synchronous mode with the other SAI block in the same SAI peripheralI'm confused about the following statements:Typically, the audio block in...
Hello, I have this code // Initialiser le bloc A fresult= HAL_SAI_Init(&hsai_BlockA1); if (fresult != HAL_OK) { return HAL_ERROR; } // Initialiser le bloc B fresult= HAL_SAI_Init(&hsai_BlockB1); if (fresult != HAL_OK) { r...
Hello Team , I am trying to use the SAI1_A on the STM32H563ZI and I am not able to read any data using the asynchronous RX Mode. The control keeps checking for status != SAI_FIFOSTATUS_EMPTY and there are no updates post that.(Although, I am using th...
