HI since fews days, i'm trying to get data from my microphone connected in stereo mode on my evaluation card B-L475E-IOT01A and give them to the DAC. According to the datasheet PE7 is DFSDM1_DATIN2 and PE9 DFSDM1_CLKOUTso i activated channel 1 on cha...
Posted on May 09, 2016 at 12:53In our project we have two boards communicating with eachother through SPI. A controller board based on an STM32F405 is SPI master over a sensor board for which we have two instances. One is based on an STM32F071, the ...
Hi. After many hours my stm32f091 board does not receive what I send to it using uart.Please could someone confirm that I'm using uart, rx and dma correctly?So this is my sequence:CubeMX -> usart1 -> DMA Settings -> add(on RX, circular, memory)Usart1...
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...
