Hello,I have used USB-CDC for some time. All STM32F3 discovery boards are rev.B (MB1035B). Recently I purchased a new one, which turned out to be a revision D (MB1035D) .Running the same code on the new board gives the famous 'USB device not recogni...
Hi guys, Does anyone know if there is any existing example to configure low lever(without using the abstraction layer) an input capture with a timer using a STM32F3 board? If so where could I find it?Thank you very much !!
Posted on November 22, 2013 at 14:27Hi All, Does anybody have an example how to lock/unlock SD card using SDIO and CMD42?
I want use two or more buffers with IO functions. One way I could imagine was if I use two different callbacks. I would call HAL_UART_Receive_IT using buffer A which calls HAL_UART_RxCpltCallback A which calls HAL_UART_Receive_IT using buffer B which...
Hello,while many STM32 have a RNG unit, only few parts, like the STM32L053, have a TRNG unit. Looking at the reference manual, I see no real difference.Is there any fundamental difference in TRNG versus RNG unit?
Greetings.I'm using STM32L051 for a project, and there are some maths calculations where I'm using single-precision floating point calculations (additions, multiplications, sinf(), cosf(), etc.).My calculation routine is taking about 7ms when using 1...
I have SD card interfaced with stm32f407 through 4bit SDIO. I am writing data from I2S _DMA_receive buffer into the sd card. This write should happen continuously,but it happens only once.Here is the piece of the code:FATFS myFATAFS;FATFS *myFATAFS1;...
Hello, In the uart driver code of STM32 CUBE layer i found this, static void UART_DMATransmitCplt(DMA_HandleTypeDef *hdma){ UART_HandleTypeDef* huart = ( UART_HandleTypeDef* )((DMA_HandleTypeDef* )hdma)->Parent; /* DMA Normal mode*/ if((hdma->Instanc...
Posted on July 11, 2011 at 21:13I'd like to use a Connectivity Line STM32's (STM32F107) I2C peripheral in the 400Khz fast mode. I'm using a Olimex STM32-H107, which has a 25MHz external crystal. I am confused by what the reference manual says (RM000...
DMA1_Stream0->FCR = 0DMA configured to work in double buffer direct mode.And I get FEIF0 error interrupt flag?
