Hello, I am using st CUBE to configure my board to read a single digital mems microphone. From reading RM0433 Table 429 and also AN5027 figure 52 I try to set the clk to SAI1 to be 2.048 but i get an issue that its not possible and can only be set t...
MCU: STM32F446VESTM32CubeIDE 1.7.0 with CubeMX 6.3.0SAI1 block A is configured in SPDIF TX mode, clock audio frequency is set to 44.1KHz.SAI Clock is approximately 2.823529 MHz. HSE freq is 12MHz.As you can see on screenshot "Real Audio Frequency" al...
Hello,We're trying to configure the H7 for use with 2x PDM mics, with an effective sample rate of 16 kHz. I believe the input clock to the microphones them selves should be 2.048 Mhz, yet CUBE MX produces an AudioFrequency field value of 16 kHz?Stran...
In the reference manual: https://www.st.com/resource/en/reference_manual/rm0468-stm32h723733-stm32h725735-and-stm32h730-value-line-advanced-armbased-32bit-mcus-stmicroelectronics.pdf there is a clock symbol mentioned called: spdifrx_symb_ck which is ...
Hello,In my project I need CPU frequency independent CANBUS and SAI2 Master clock output.CANBUS is running out of PLL2P clock, while SAI2 MCLK is selected from PLL3PIf I only enable one or the other, they work great, but if I enable them all together...
hello, i'm using stm32h745 mcu. i want to using SAI interface to use MEMS MIC, ADAU7002 .this sensor transmit 20bit PCM , 22050 hz data.i used CUBEMX and SAI & DMA setting is here. i can't select SAI interface data size 20bit, so i fixed HAL Driver ...
I have created a clock of 38.4MHz for SAI4A and SAI4B but I am not able to get 24.0kHz sample rate for a I2S 32bit Master input.All sample rages seams to relate 4.8MHz clock.
I have a code that mdma can access any variable feed to it by &var (AXI SRAM) also I have gave it an address of ADC common registers from APB1 but adress from APB2 &hrng.Instance.DR causes HAL_xfer_read_error. Any idea? I know in reference manual it ...
Is it possible to obtain a (theoretical) 48kHz sample rate with 0% error on the STML5's SAI peripheral? So far the clock configuration tool in STM32CubeIDE has been unable to do so.Research led me here, but this is not applicable to a slower clocking...
Datasheet claims that with FSDEF=0 (FS signal is start frame, not channel identificaion) i can set up number of slots (NSBLOT) to any value. In my case 1. CubeMX claims that it must be equal two (which is not true). When i try to set value to 1, then...
