Hi everyone,
I would like to send datas by USB in full speed with a CY8C5888 but I don't understand that if I should use a driver or if I can directly connected Dplus and Dminus from the USB cable to the pins of PSoC. FYI: I will supply my PSoC in 5V
Thank you

Hey
actually I already saw this video, and on the freeSoc it doesn't use driver for USB so I supposed that I don't need a driver. Another question, how do I know if a crystal is required? On example's datasheet it 's write " The PSoC devices include a dedicated Full-Speed (FS) 12-Mbps USB 2.0 peripheral, which uses an internal oscillator—a crystal is not required. " but on FreeSoC there is a crystal connected.
Thank you

Using an X-tal for USB on a PSoC5 LP is optional, when not used a special setting of the clocks is required to stay within the needed precision. Settings will be hinted to when clock window is opened.
Set the IMO to 242MHz and the ILO to 1kHz, USB-clock to IMOx2
