HiI own a STM32F469-Discovery Board bought in 2021. There seem to be (at least) two revisions of that board, "B" & "C" and maybe "A". Under "CAD Resources" are just schematics for Revision "B" and "C".If I try to run the supplied example for that boa...

HiI just testing some options for a future project which possibly involves a STM32F479VIT and I try to understand if it can handle an IS42S16400J-7TL SDRAM module.So I created a test project in CubeIDE but it does not show any SDRAM option in the FMC...

HiBecause people slowly seem to move to wayland I installed sway-wm and tried to start CubeIDE. But while typing and pressing CTRL-SPACEBAR no autocompletion drop down appears. Is this a known issue with CubeIDE on wayland?

Hi thereI got an IC that needs to be fed with 32bit NOP words via SPI TX (0x00000000) to get 32bit data output via RX at the same time. Communication works fine in SPI polling mode but I really want to try to do it via DMA...My RX buffer is an array ...

HiIn your Reference Manual for the STM32F469 at 31.3.11 it says:A DMA access is requested when the TXE or RXNE enable bit in the SPIx_CR2 register is set.But the SPIx_CR2 Register does not have a TXE/RXNE bit, it has a TXEIE/RXNEIE bit which just en-...

I am on Arch Linux. The problem seems to be a mixture of your explanation and the window manager "sway" I used. I switched to KDE-Wayland and auto-completion worked but like you wrote creating new STM32 projects does not work.So this is a showstopper...

Thanks, I think I got it. I changed the txBuffer array to an normal uint16_t initialized with 0 and changed TX MemoryAddress accordingly. I set both TX/RX datalenghtto maximum of 65535 and as suggested TX MemoryIncr. to none.I enabled DMA RX TC inter...
