Resolved! How to Manually Use DMA for USB Device
I made a High Speed USB DEVICE using USB PHY with STM32F207.When delivering data to the HOST, there are small-sized data (less than 512bytes) and large-sized data (more than 1Mbytes).At this time, I want to transfer small-sized data without using D...
Resolved! How do I transfer data over 0x80000 from USB DEVICE?
I made a High Speed USB DEVICE using USB PHY with STM32F207.A data transmission test to the host is in progress, and transmission is possible up to the size of 0x7FFFF, but it cannot transmit more than that.When referring to stm32f2xx_ll_usb.c, the m...
