The program uses a hall effect sensor to calculate when a metal ball needs to be released by a magnet to drop through a hole in a spinning disk. It was was written for a PIC16F84A with an external clock of 4MHz.
Some data types are of course smaller than what you expect. The following table is just for reference to not forget about it.
| Type | Size (bits) | Arithmetic Type |
|---|---|---|
| bit | 1 | Unsigned integer |
| signed char | 8 | Signed integer |
| unsigned char | 8 | Unsigned integer |
| signed short | 16 | Signed integer |
| unsigned short | 16 | Unsigned integer |
| signed int | 16 | Signed integer |
| unsigned int | 16 | Unsigned integer |
| signed short long | 24 | Signed integer |
| unsigned short long | 24 | Unsigned integer |
| signed long | 32 | Signed integer |
| unsigned long | 32 | Unsigned integer |
