Musical Greeting Card

Step 7Program the melody

Program the melody
The melody is in the form of a HEX file and will have to be programmed into the device. You can use any of the PIC programmers avalilable out there, they need five connections to be made to the chip, as shown.

The Hex file for the tune of "Go Tell it on the Mountain" is provided here.

Do you know if those pins can be programmed with more than a simple melody. I am thinkin of a full 3-5 minute song with vocals and all.

i did some googling and found out that there are reprogrammable PIC chips out there. is it possible that the chip from my music card is reprogrammable? if i were to get a new module, where can i get the necessary hardware that connects my computer to the card to program it?

Pretty much all pic microcontrollers are dead easy to reprogram, the problem is that when they're programmed at the factory, they can set a bit high that makes the chip unreadable, to prevent a company from stealing another company's code, unfortunately it also makes it unwriteable.
