I need a C code that makes some of these devices work. (display, switch, second display, serial port or keyboard) . It has an 8051 microprocessor(AT89C52 Microcontroller) and 11.0592MHz clock frequency. It's on proteus and I am using Keil(don't know if this matters). I am also putting the device list below. I am new to the topic so let me know if any information is left out. Thanks in advance.
