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...
