Access Raspberry Pi GPIO with ARM64 assembly
Components
Any general-purpose NPN transistor (2N4400, 2N2222A, BC548, etc.) will work. Likewise, any four-digit, common anode, seven-segment display will be fine. Because this project uses AArch64 assembly language, your Raspberry Pi must be running a 64-bit distro like Ubuntu 20.10.
Have fun!
