> then backspace seems to generate some incorrect code/character in MWdemo
text input field
@ppisa, this looks like the NuttX HID driver maps the Backspace key to ASCII
DEL. I had handled that in the mw kbd_nuttx_raw driver before,
```c
static MWKEY raw_byte_to_mwkey(uint8_t ch)
{
switch (ch)
{
case 0x7f:
return MWKEY_BACKSPACE;
case 0x0a:
return MWKEY_ENTER;
default:
if (ch < 128)
{
return (MWKEY)ch;
}
return MWKEY_UNKNOWN;
}
}
```
but didn't do the same in the event driver (because at that time the usb hid
driver haven't updated to event path yet). Applying the same handling to
kbd_nuttx_event should fix it.
I have opened a pr in mw to solve it
https://github.com/ghaerr/microwindows/pull/199 . Once it is merged, I will
open a pr in nuttx-apps to change the commit hash used in Makefile.
By the way, thanks for the reminder, I have already submit the materials for
final evaluation.
