The PIC16F877A is used to support detecting and handling external events. For example, assume a Can of Coke in a vending machine costs $.75. The accepted coins are quarter ( 25 cents) and dime ( 10 cents), and nickel (5 cents). The user may insert coins in any sequence. Detect each coin type using any interrupt types associated with INT and RB. There is a need to develop a program in PIC assembly language to detect the coins input to the machine and check if the total adds up to exactly or more than $0.75. Then, the vending machine should dispense a Coke by writing the value 0xBB to location 0x25 in the data memory space (GPR) and then display it on Port C. Note: To write the program, you can use suitable equivalent numbers to represent the allowed Coin values. The PIC16F877A is used to support detecting and handling external events.
