- Merge Makefile and Makefile.include into Makefile
- Format structure
- Remove unused variables, targets etc.
- Add missing check if it is ok to send data to the FPGA.
- Remove 'baud rate calculator.ods'
- Update encode_usb_strings.py to generate strings for
CdcCtrlInterfaceDesc, CdcDataInterfaceDesc,
FidoHidInterfaceDesc, TkeyCtrlInterfaceDesc.
Also store generated strings in UTF-16 instead of hex.
- Update usb_strings.h to match new encode_usb_strings.py
output.
- Remove unused struct SetupReqBuf.
- Move copying of TKEYCTRL data from UartRxBuf to TkeyCtrlRxBuf to align
with previous code.
- Remove obsolete UartRxBufOverflow variable.
- Add missing Endpoint4 handling for USB bus reset.
- Fix more robust uart_byte_count() calculation.
- Fix baudrate fast mode calculation to get rid of compiler warning.
- Fix assignment of bUD_PD_DIS to UDEV_CTRL.
- Cleanup comments.
Fix CDC configuration problem on Windows when we have a composite
device (multiple different Device Classes). Add "Interface Association
Descriptor" to make it work.
- Use CTS signals to let the FPGA and CH552 signal each other that
it is OK send UART data.
- Update the CH552 rx and frame handling logic.
- Fix minor spelling errors and indentation
- Add USB HID support.
- Introduce a small protocol to distinguish between CDC and HID data
sent over the UART.
- Add some debug printing.
- Cleanup of code and formatting.
