Hello everyone, I'm a complete newbie to code writing and I'm very keen to learn, I do have some experience in flashing PIC's as I have a Pic Programmer and have flashed hex files to PIC16F84's, But this was pre written code from someone else and then as I understand exported to HEX from and ASM file.
The Code I need is for the 12C508A, Which is a controller for another IC ( MC145170P2 ) which is a Phase Lock Loop stabilizer for an FM Transmitter, The 12C508A contains the Data that tells the MC14517OP2 what Frequency the transmitter should be operating on.
I do have a 12C508A at home and when I tried to read it, the code was protected. This 12C508A I have has code written for 107 Mhz. I looked around on some forums and I found that the code was not completely protected, something about the last 64 or something being unprotected,
I do have a hex backup of it, I clicked on a tab in my Pic Programming software saying disassemble I think, But anyway I have an ASM file of something maybe this can help speed up the code writing.
