I am trying to make a guitar loop pedal with my nucleo-l476rg board. It has 1MB of flash and I am trying to write and read from bank 2 only as it is the bank of memory I want to use for storing recorded audio. I currently have an active buffer set up...
I'm trying to go about creating a USB Audio interface on a NUCLEO-H7S3L8, receiving USB audio and forwarding it to the SAI, in order to send to an external DAC.Among other tests, I went back to checking when the functions in usbd_audio_if.c get calle...
Hi, I am having issues with threadX tx_byte_allocate throwing a hard fault exception. This only happens after some time of byte allocate and release. There are still plenty of available bytes according to the pool. But somehow in _tx_byte_pool_searc...
I just had a quick question to clarify my understanding of how byte allocation works for thread stacks in the ThreadX RTOS. I've seen the official examples use a byte pool and then allocate bytes from that pool before creating a new thread. However, ...
I'm working on entering and exiting low power run mode at runtime on Zephyr rtos. I can't find a way to change clock frequency to 2MHz (required by LPR) and back to 80MHz using zephyr features at runtime. Is there any api to achieve this, or some si...
I'm trying to implement a USB touchscreen on a NUCLEO F446ZE. I'm making a full-speed device using ST's USB library (Custom HID class) and I'm testing it with on a Windows 10 host. The first contact registers, but when I try to press another, it doe...
Hopefully i chose the right thread, right so i have sn stm32h523 chip running a PCISPH fluid simulation, but its incredibly slow, that was expected, which is why i optimised the algorithm to include spatial hashing to reduce particle-particle computa...
There's a serious bug in G4's hal(version 2.0.0) library in spi dma function.The problem is:1, user calls HAL_SPI_TransmitReceive_DMA2, after spi transmission finished, HAL will call HAL_SPI_TxRxCpltCallback3, user calls HAL_SPI_Receive_DMA inside HA...
In stm32u5xx_hal_flash_ex.c, version 1.6.2, FLASH_OB_GetUser() is defined as:/** * @brief Return the FLASH User Option Byte value. * @retval The FLASH User Option Bytes values. * The return value can be a combination of @ref FLASH_OB_USER_BOR_LEVEL, ...
I am currently experimenting with STM32F030RCTX and STM32F030CCTX devices.My goal is to use RS485 with auto-baudrate detection, since I have modules that operate either at 115200 baud or 500k baud.On STM32F030RCTX, I use USART1.On STM32F030CCTX, I us...
