Thanks for the reply.
I’ve tried with all ASCII characters, and except for the comma (,), every symbol is displaying fine. For the comma, a hyphen is displaying instead.

Thanks

I have been having the exact same issue. I configured my USB keyboard via the lv_indev functionalities. Pressing the “comma” key will yield the ASCII equivalent “44” in the callstack for as far as I can follow it. lv_textarea_add_char gets called and the callback I attached to the textbox receiving the keystroke when in focus does a memcpy() on the data in the textbox matches what I expect. I suspect the issue is somewhere in the drawing of LVGL but it’s difficult to track what and when. I am using the NXP RT1176 as well with version 8.3
