SpoilerHi Friends, I have a problem using the DAC with the DMA. I have configured the DAC's DMA in normal mode and I want it to generate an interrupt at the end of data transmission to let me know that it has sent all the data to the output. The dat...

Hello friends,I write this post to ask for a hand in choosing a low -price micro stm32 that can read an .mp3 file from an SD card. The customer wants a really low cost and therefore I cannot go to use microcontroller with 100 pins, but I have to use ...

Hi Guys, I'm working on a personal project. I have experience with the use of STM Nucleo and this time I don't know how to get out of my problem. Previously I have already used the UART peripheral in the same way that I am using it now, but now it ha...

Hi, I am experimenting with the Nucleo-L452RE-P the ALTERNATIVE FUNCTIONS of the PA6 pin, what I need is that the pin acquires a rising edge through the Timer Direct Mode generating INTERRUPT, this works correctlyvoid HAL_TIM_IC_CaptureCallback (TIM_...

Thank you very much now I understand better, I will try to work and solve this problem to have an interrupt on the falling edge. I thought it was a bug of the STM32L452RE instead I understood that it was working correctly.@KnarfB Thanks for the examp...

I think it is not correct to say that I observe a delay of two samples, but rather that the DMA thinks it has transmitted all the data to the DAC when in reality there are still two data points to send out.

I did some tests using a defined signal to transmit on the DAC and a physical pin that goes high when an interrupt is generated. The array signal that is transmitted on the DAC is composed of 10 different points and when it transmits the eighth value...

can you tell me exactly if I should use SPI or SDIO? I chose the µ STM32G431KBU6 which reads the .mp3 file and translates it into a DAC value with low precision
