Is it possible to view 16x2 LCD register values as a peripheral in debug mode?

sebin_sebastian over 2 years ago

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?
