Hi,I try to run "FatFs_Shared_Device" example which supposed to demonstrate FatFs and eMMC.I keep getting FR_DISK_ERR.Has anyone ever encountered this issue?I understood it supposed to work without any modification to the example.Thanks guys
I am working on using open_bootloader with CAN(STMG0B1CB).After successfully writing 256B(in packets of 8B each), I try to read back.After some amount of correct read-backs(to verify), the communication fails randomly.Any suggestions?
TLDR:I'd like to send 1000 key presses per second over USB to my PC, but USBD_HID_SendReport() blocks for at least 1 ms, so the best I can currently achieve is 500 reports per second.More detail:I'm using STM32CubeIDE with an STM32H750 board connecte...
