HI, I am trying to develop a application with a accelerometer over 5kHz.I have some samples of LIS3DH. Does exits any repository of mem senc?I search in cubemx but is not there.I can write the library from datasheet but it is a lot of time and it wil...
Hi!I'm trying to get an SPH0645 microphone to send sound data to my STM32F411 with HAL_I2S_Receive(), but the data I receive is not correct. According to the data sheet, the microphone gives 24 bits data on a 32 bit frame, with 24 bits containing dat...
Hello everyone,I have an application that eventually record some audios and is working fine with a pair of MP34DT01. It works over SAI with a clock of 1.024MHz and a decimation factor of 64 (for the PDM2PCM), leading to an audio frequency of 16kHz.Th...
Hey guys we are using the HAL Uart at 9600 Baud between our Bluetooth Board and Motion Sensor. We are using the DMA in non circular Buffer mode and then we have an actual Circular Buffer the Data goes into after the DMA. We are noticing randomly the ...
Hi,I've configured the LSM6DSO with an NRF52. The NRF52 is able to use DMA and to trigger the SPI clock for bulk read in background without incorporating the CPU. But as far as I can see in the datasheet and the example drivers the LSM is not capable...
I'm trying to get data from PDM microphone and convert it to PCM data. This is my first project on stm32 and I'm starting to debug the project. Could you take a quick look at my code and say if you notice something wrong ? Some part of the code come ...
ADC Sampling rate :-Total Conversion Time (Tconv) = Samplingtime + 12 (This 12 is for 12-bit resolution of ADC). If I set 12.5 Cycles in MX based on the settings of the controller STM32L9RI My ADCCLK Cycle will be =24.5 . Please confirm whether 12 to...
Hi, I have an application where I am using NUCLEO F401RE interfaced with Nucleo-CCA02M2 and a sensor. I am running two tasks one is reading data from sensor via I2C and other reading audio from I2S via DMA. THe sensor uses an interrupt line which w...
Hello everyone,I'm interfacing a digital MEMS microphone with a stm32l152re mcu cortex M3 using I2S with DMA In order to measure sound pressure level. the communication is based on acquiring PDM ( Pulse density modulation) values that represents the...
Hi,I am currently working on DMA combined with I2C bus. I want to read acceleration data from IKS01A3 with HAL function HAL_I2C_Mem_Read_DMA(). I want to read at 6 different memory registers. How can I use that function to get it work properly? Can I...
