I made a small wav-music player with a STM32L452. Reads data from SD card via SD 1 bit mode, and plays it over the DAC. Homemade jukebox, fun little project.My problem is: while all the small cards (up to 8 gig) I tested are o.k, larger cards do not ...
I'm implementing two channels of DMA in my STM32F302x using Timer 2 in input capture mode. Do I really need the HAL_DMA_RegisterCallback callback function? I'm using DMA interrupt mode so each channel has a DMA1_Channelx_IRQHandler that performs the ...
I need to receive signal information in percentage %.How can I convert/change received information ?Thank you
HI All,I Have the STM32F302R8. I am using comparator 2. What I want to do is have DACH1 feed a value to the inverting input and have PA7 connected to the non inverting input. For now, I am just wanting to generate an interrupt to get things working ...
I am using an NUCLEO-F429Zi to read a MPU over I2C ( 2C1, PB8, PB9). The applications works correct. The sensor returns the correct values. When the ST-Link is removed (cut away) from the board, the power supply Vin , the I2C connectivity fails. It ...
i can switch between all pin but this one is static, pin PC14 (I call it olcl).I think maybe one of the peripheral units in the card is catching it to me.this is the code and the setup.sbs_pol_Pin is swiching states properly. while (1) { HAL_GPIO_Wr...
I am using NUCLEO-G474RE as my hardware.STM32CubeIDE V1.3.1 and STM32G4 Fw V1.2.0.I am using ADC2 with 4 channels triggered by HRTIM CH B Compare 4 Injected.So these 4 channels are triggered interleaved, meaning that every HRTIM-CH-B Compare 4 only o...
Hi, I would like use the DMA functionality for SPI on my STM32F4. But all examples I have found are calling the SPI DMA Transmit Receive function in a while loop. But what would be a better way? I think that if I call the Transmit Receive function ...
I'm using the project "SPI_FullDuplex_ComPolling_Master" in P-Nucleo-WB55.Nucleo/Examples_MIX/SPI in FW version 1.6.0. Works fine on the nucleo board. I've ported it to my board which uses pins PB5, PB4, and PB3. I'm using a crystal on my board. I di...
While trying to read ADC value over voltage divider I accidentally connected not divided voltage to ADC pin. That was about 10V and with burnt smell I promptly intervene and cut the connection. The board was hot but I could touch it. After that I pu...
