- Note
- Based on HiTech DELAY.C examples.
Note that there are range limits: x must not exceed 255 - for xtal frequencies > 12MHz the range for DelayUs is even smaller. To use DelayUs it is only necessary to include this file; to use DelayMs you must include delay.c in your project.
Set the crystal frequency in the CPP predefined symbols list in HPDPIC, or on the PICC commmand line, e.g. picc -DXTAL_FREQ=4MHZ
or picc -DXTAL_FREQ=100KHZ
Note that this is the crystal frequency, the CPU clock is divided by 4.
MAKE SURE this code is compiled with full optimization!!!
