Block parameters for USB FS and HS interface

• USB type – switch between USB FS and HS
• Receive mode – (only support Binary mode)
• Header settings->Hex format – supports hex format of header
• Frame repeat – frame repeat counter (if 0 send once)
• Input data->Input data type – (only support auto data type)
• Input data->Enable input length – enable length definied by input
• Input data->Input length – length of input data (Enable input length->Disabled)
• Header/Terminator->Enable Header/Terminator – anable add header and terminator to frame
• Header/Terminator->Hex Header/Terminator format – supports hex format of header and terminator
• Header/Terminator->Header – header of frame (e.g. ‘START’ in non hex format and e.g ‘0x53 0x54 0x41 0x52 0x54’ for hex format of header
• Header/Terminator->Header length – length of hex header in bytes (only for hex format enabled)
• Terminator settings->Header – terminator of frame (e.g. ‘END’ in non hex format and e.g ‘0x45 0x4E 0x44’ for hex format of terminator
• Header/Terminator->erminator length – length of hex header in bytes (only for hex format enabled)
• Timeout – timeout in ms

Explain output „Status”

• Status „0” – Add to buff error
• Status „1” – Add to buff OK

Settings for STM32H7 USB FS and HS
