I need to send a single address byte with write bit and read bit.For the write, I'm using HAL_I2C_Master_Transmit_IT(&hi2c4, I2C_ADDRESS, (uint8_t*)i2c_buff, 0)It works perfect, it sends a start, single address with write bit cleared, slave device AC...
Can someone please guide me with 8KHz audio, echo cancellation is almost perfect for 16khz audio on stm32u5, but seems problematic at 8KHz, i've tested pass-through (loopback, mic connect to speaker) at 8Khz and it is clear when AEC is disabled, also...
Hi,I have implemented CDC USB device on my custom board using STM32C071CBT6. When i connect USB cable to host PC then I can see Virtual COM Port on PC as 'USB Serial Device (COMxx)' However, I tried transmitting some data which I could not receive on...
Current Situation: I have implemented a bootloader that receives a .hex file and writes the application starting from Sector 2. After successfully jumping to the application, the system runs as expected. The Problem: Once the application is running, ...
I used "generate-n6-model.sh" script to generate "network_data.hex" file as in the repo. However, it didn't match the original file. As a result, when I programed it to dev board "STM32N6570-DK", the app only shows images, and didn't detect persons. ...
Good afternoon,I'm using the STM32H723ZG Nucleo Board, and I'm trying to collect data using I2S + DMA coming from a PCM1803AEVM that is a 24-bit ADC used mostly for audio purposes.I've set the PCM1803 as controller (MASTER), it is generating the BCK...
I am using STM32G030 for my project when using version Z (REV_ID 0x1001) the functions in the firmware run as required. But when using the same firmware, the above hardware loads version Y (REV_ID 0x1003) the functions run incorrectly, especially the...
Hi everyone, I was wondering if is it valid to allocate DMA buffers for USART/SPI etc.. on the heap using aligned_alloc() function?My board is the NUCLEO-H743ZI2 If its possible - is it good practice?Thanks, Ariel
I have some code on the STM32G030 processor using only LL drivers.I need to write on some area in the flash of the processor.I undestood that there is no LL driver for Flash, but the proble is that If I try to use some HAL functions, like HAL_FLASH_U...
Hello, I'm running into an issue interfacing the STM32H7R3V8H6 with a MAX31856 where whenever I try to use any sort of SPI functionality, it returns HAL_Error. This issue surprises me because the code that I am using is identical to the code I used o...
