Programming PIC Microcontrollers in BASIC - mikroElektronika
Note that the programming software should be used only for the communication with the
programming device — it is not suitable for code writing.
1.6 Running the program
For proper functioning of microcontroller, it is necessary to provide power supply,
oscillator, and a reset circuit. The supply can be set with the simple rectifier with Gretz
junction and LM7805 circuit as shown in the figure below.
Oscillator can be 4MHz crystal and either two 22pF capacitors or the ceramic resonator of
the same frequency (ceramic resonator already contains the mentioned capacitors, but unlike
oscillator has three termination instead of only two). The rate at which the microcontroller
operates, i.e. the speed at which the program runs, depends heavily on the oscillator
frequency. During the application development, the easiest thing to do is to use the internal
