Hello NG,
i a very new to microcontrollers. The last weeks i have connected a HD44780 Display on my ARM, which works perfectly! Now i want some User- Interactivity via a Pushbutton. I can=B4t figure it out, how to manage it. This is what i am doing:
ldr r0, =3D0xFFFFF400
button: ldr r1, [r0, #0x08] and r1, r1, #10000000000000000000b cmp r1, #10000000000000000000b bne button
It doesn=B4t work. Has anybody some example for me? Thanks a lot for any hint! Peter
