Looking for others who may be developing Adruino code on Linux hosts. I am not able to configure my systems to utilize the four numeric keypad arrow keys(4,8,6,2). Pgup/PgDn/HOME/END all work. Tryping the formulars for the selfbalancing robot filters without the normal keypad is a pain. Only solution so far is to configure the IDE to use an external editor. Problem is only with the editor, menu keys and serial monitor behave as expected.
numlock & INO
Its not the num lock. The keys work as expected in the file menus and serial monitor. Plus they work with emacs. The behavior is the same on a laptop with integrated keyboard or wireless keyboard plus and older PC with the dedicated keyboard connector. Laptop is a dual boot and the keys work fine with the Windows Adruino editor. I suspect its just Linux, perhaps just CENTOS.
I will look into INO. I prefer to build with Make and command line. Thought it was time to play with some “modern” tools but the Arduino IDE seems a little to sparse. If it supported breakpoints, peripheral and memory dumps it might be useful.
