My device use STM32L0 controller and Hal USB Device CDC class is implemented in it. When connected to Windows 10 OS the "Device description request Failed" message is shown. But on updated windows 10 OS it is working fine as it should. So is there a...
Hi,I have 2 eval boards STM32F756G-EVAL2 and STM32F779I-EVAL.I am using this example from STM32FCube library\en.stm32cubef7\STM32Cube_FW_F7_V1.14.0\Projects\STM32756G_EVAL\Applications\ExtMem_CodeExecution\ExtMem_Boot .I am able to run this sucessful...
Hi, guys. I'm curious whether anybody has tested the Opus Audio CODEChttp://opus-codec.org/using STM32F4 MCUs.I have both the NUCLEO-F446RE board & STM32F4 DISCOVERY board.Is there an example to play music using Opus?Any extra video demo for Opus usi...
Hi there,i managed the get a working composite device with working driver files. I can choose between all combinations of cdc,hid and msc.But i can't connect to my serial com port. I want to use this com port as a uart bridge but it's not working bec...
typedef enum { HAL_OK = 0x00U, HAL_ERROR = 0x01U, HAL_BUSY = 0x02U, HAL_TIMEOUT = 0x03U, } HAL_StatusTypeDef;This is the actual defintion of the HAL_StatusTypeDef. Other status codes are defined in other modules headers ...
I am generating a special signals with GPIO. It is unique protocol signal to communicate with other system.To make signal timing, I ran one of TIMER counter and check the value in a while loop.But, the problem is from USB connection. If I don't conn...
Hello,I have a STM32H743ZI with FreeRTOS and SDMMC1 initialized from MxCube 5.0.1.I'm currently using the FreeRTOS-FAT.When i try to call a HAL_SD_WriteBlocks_DMA() with 4bit wide bus, I always get "HAL_SD_ERROR_DATA_TIMEOUT" in the IRQ Handler. With...
The CubeMX samples have an MP3 encoder, but it appears to be a binary blob rather than source, and locked to certain chips & versions of the libraries. Is it possible to get the source or is a compiled version available for the STM32F733 / STM32F723?
Proper use of the HAL library for SPI communications.OK, first, I am very new to this and I am slowly learning as I go.The project I am working on is a radio beacon in the 430MHz range. I have a Nucleo-F446RE board and a RFM23B transceiver module. I ...
Ok, another noob question....I can use the following line of code in the main.c with no issues#define Green_LED_OFF HAL_GPIO_WritePin(GPIOA, GPIO_PIN_8, GPIO_PIN_RESET); // Green offBut when I want to use it in another .c file such as foo.c I get th...
