I've connected a 16X2 LCD to STM32F401 board and successfully printed characters on the display. However, is it possible to view the contents of the LCD registers (data and command registers) while in debug window? We can view all register contents of the inbuilt peripherals in the STM32F401 board, but does that feature work for external devices like LCD also?
I understood the question, but perhaps did not answer well.
A. No
Unless there is an MCU that has the equivalent of a built-in HD44780 controller, or someone has made plug-in software(?), then I think the answer stands. Love to be proven wrong though.
Ok. thanks for the answer.
