Resolved! STM32F4 Use HSI for USB Clock
I want to use STM32F413 for my PCB design. I need USB data lines for communicating with a computer. Ideally, I would not have any oscillator on the PCB to save space. I noticed that's it's not possible to use HSI for the USB clock on CubeMX. Can I us...
What's wrong with the compare in STM32F373?
I use MDK 5.32. In the debug interface - Peripherals - System Viewer - COMP window, the value of CSR is always 0 after initialization and the address of CSR is viewed as 0x40007C1C. But CSR's address is 0x4001001C in STM32F37xc.h. What's the mat...
STM32H7 USB OTG HS: Four highest OTG_HS_DIEPTXF registers mirror the low ones
I am trying to set the FIFO sizes for an application that uses 6 bulk IN endpoints. When I write to OTG_HS_DIEPTXF1, it appears that OTG_HS_DIEPTXF5 takes on the same value. Same for DIEPTXF6 taking on the value of DIEPTXF2, and for DIEPTXF7 taking o...
