In the X-CUBE-PWM-DITHR example application, which is supposed to accompany AN4507, PWM dithering is demonstrated by TIM1_CCR1 modified using timer-update-triggered circular DMA from an array of values, which is in turn generated in the DMA half-co...
I am writing a custom bootloader that gets hex of new user code via usart and writing on flash.Now the system jumps to another sector and the new code works. But after presing the reset buton, the system turns bootloader .How an I fix this problem?Th...
Hello All,I am using the usbh_core module to enumerate mass storage devices as a host. I have had it work for plenty of USB 2.0 sticks (not for 3.0), but suddenly, a large batch of USB 2.0 sticks fail to work. After extending all of my delays, this s...
Hello,I am using the STM32F7 for USB communication as an MSD host and using the usbh_core.c code and all of it's associated pieces. I have it working consistently on USB 2.0 devices (side note: I needed to insert an enumeration retry for certain non-...
Hello,I am having an issue connecting to specific USB mass storage devices with my STM32F769 USB host using the BSP. It seems like the USBH_GetDescriptor function never returns for USB flash sticks with a specific HID PID combination. I am considerin...
Hi All,I have been utilizing the STM32F7 to take and store pictures on USB 2.0 sticks.I have repeatedly run into variation across sticks that requires that I modify the MSC Host HAL supplied by STM. The most recent issue that I have run into is getti...
