Convert Dec --> Hex
	One of the first creations with PICs. The function is to convert a decimal value to hexadecimal. Button functions: P 1 OK proceeds with the calculation: P 2 Increases the set value: P 3 Sel Tens/Units selection: P 4 Reset. There is no electrical diagram, but the various connections can be deduced from the ASM listing. Quartz is 4 MHz. As mentioned, it is also a creation for educational purposes, in fact the listing in ASM is linear and I used various parts of the program to create macros used in subsequent projects.
