I want to make a sound gen. connecting with a LCD module and several LEDs. It looks like a "electronic piano".. however, before compiling the program, i am vague in connecting the pins of all the components to the 8051 micro-controller.. please indicate me which parts i did badly..thank you!!
the LCD module, even i have the datasheet.. except Data bit 0~7, VCC and GND.. i dunno which pin(s) i should also connect.. can u teach me? thanks a lot !!!
