We use TUSB3410 without problem as UART Bridge in our design, but now we wish use it as hid keyboard.
I'm not building a keyboard, but uart to keyboard bridge. Data received to serial port must be send as keyboard hit.
For test i have one tusb3410 UART PDK. I've downloaded TUSB3410GPIO-SRCCODE, keyboard is working but not the serial debugging fonction.
Using standard 8052 register to configure serial (sllu027a.pdf firmware debugging appnot is not working
Using LCR, LSR
I've modified source code to use UART, but i have problem with FIFO: if FIFO is not full RXF bit of LSR register is not set. When FIFO is full we lost 1 byte to get 1 byte.
If FIFO is disabled, no data is received by mcu. i
For test i'm juste trying to echo the byte received on uart.
Have you sample to use TUSB3410 UART without USB troughput.

Alexandre
