Getting StartedChapter Programming LoopsChapter More LoopsChapter InterruptsChapter The compiling procedure takes place in two consecutive steps. Step 1. ASM file.
Step 2. In the second step compiler automatically calls assembler, which converts ASMtype file into an executable HEX code ready for reading into the programming memory of a microcontroller.
The transition between first and second step is for a user - programmer an invisible one, as everything happens completely automatically and is thereby wrapped up as an indivisible process.
In case of a syntax error of a program code, the compilation will not be successful and HEX file will not be created at all. Errors must be then corrected in original BAS file and repeat the whole compilation process.
The best tactics is to write and test small parts of the program, than write one gigantic of lines or more and only then embark on error finding. HEX - executable file which is written into the programming memory File with the HEX ending is in effect the program that is written into the programming memory of a microcontroller.
The programming device with accessory software installed on the PC is used for this operation.
Programming device is a contrivance in charge of writing physical contents of a HEX file into the internal memory of a microcontroller. The PC software reads HEX file and sends to the programming device the information about an exact location onto which a certain value is to be inscribed in the programming memory.
HEX is given. Besides reading of a program code into the programming memory, the programming device serves to set the configuration of a microcontroller.
Here belongs the type of the oscillator, protection of the memory against reading, switching on of a watchdog timer etc. The connection between PC, programming device and the microcontroller is shown.
The programming software is used exclusively for the communication with the programming device and is not suitable for any code writing. The one comprising text editor, software for programming microcontroller and possibly the simulator as an entity bears the name IDE i.
Integrated Development Environment. The supply of the microcontroller can be organized with the simple rectifier with Gretz junction and LM circuit as shown in the picture below.
Basic for PIC Microcontrollers 8 The oscillator of the microcontroller can be a 4MHz crystal and either two 22pF capacitors or the ceramic resonator of the same frequency ceramic resonator already contains the mentioned capacitors, but contrary to the oscillator has three termination instead of only two.
The speed at which the microcontroller operates i. Minimal hardware configuration necessary for the operation of PIC microcontroller After the supply is brought to the circuit structured according to the previous pictures, PIC microcontroller should look animated, and its LED diode should be twinkling once each second.
There are some suggestions that may be useful in order to help bringing to Step 1.
If the pin remains Basic for PIC Microcontrollers 9 disconnected, it's level will be "floating" and it may work sometimes, but usually it won't. Chip has power-on-reset circuit, so that appropriate external "pull-up" resistor on MCLR pin should be sufficient.
Check whether the connection with the resonator is stable. Step 3. Check the supply. PIC microcontroller spends very little energy but the supply must be pretty well filtrated.
At the rectifier exit, the current is direct but pulsing and as such is by no means suitable for the supply of microcontroller. If PIC microcontroller supervises the devices that pull lot of energy from the energy source they can in their own rights provoke enough malfunctioning on the supply lines so that the microcontroller can stop working normally and start revealing somewhat strange behavior.
Even seven-segmented LED display may well induce tension drops the worst scenario is when all the digits are 8, for then LED display needs most power , if the source itself is not capable to procure enough current for the case of 9V battery just for an example.
