| - | ====== Minimum setup for a PIC16F1455 on a Breadboard + PICkit3 ====== | ||
| - | |||
| - | If you need a quick setup for the PIC16F1455, fast wiring and code to check output from a pin, this article is for you. | ||
| - | |||
| - | Firstly, the breadboard layout: | ||
| - | |||
| - | {{ :pic16f1455-layout.png?nolink |}} | ||
| - | |||
| - | Shown is the 6-pin header where you connect your PICkit3. | ||
| - | |||
| - | <code> | ||
| - | PICkit3 Pin 1 - red wire -> orange wire -> MLCR on Pin 4 | ||
| - | PICkit3 Pin 2 - yellow wire -> blue wire -> VCC on Pin 1 | ||
| - | PICkit3 Pin 3 - green wire -> Ground on Pin 14 | ||
| - | PICkit3 Pin 4 - grey wire -> PGD (ICSPDAT) on Pin 10 | ||
| - | PICkit3 Pin 5 - purple wire -> PGC (ICSPCLK) on Pin 9 | ||
| - | </code> | ||
| - | |||
| - | Connect an LED and 100 ohm resistor from RC3 (Pin 8) on the PIC16F1455. Run the ground side to PIC16F1455's ground pin (Pin 14). | ||
| - | |||
| - | That's all you need to wire up the breadboard. Ensure to power the board using the PICkit3. | ||
| - | |||
| - | Fire up **MPLAB X** and start a new project based on the PIC16F1455. Create a new C file under the source folder. Add the following code: | ||
| - | |||
| - | <code c> | ||
| - | #include <stdio.h> | ||
| - | #include <stdlib.h> | ||
| - | #include <xc.h> //include for all pic projects | ||
| - | |||
| - | int main(int argc, char** argv) { | ||
| - | |||
| - | TRISC = 0b00000000; //set all pins on Port C to Output | ||
| - | PORTC = 0b00000100; //set pin RC2 to 5v or ON. | ||
| - | | ||
| - | return (EXIT_SUCCESS); | ||
| - | } | ||
| - | </code> | ||
| - | |||
| - | In the ''TRISC'' above, all pins are set to output with 0. With the ''PORTC'' setting, the third pin, or ''RC2'' is being turned on. | ||
| - | |||
| - | Compile the code and use **MPLAB IPE** to send the resulting ''.hex'' file to the microcontroller. | ||
| - | |||
| - | The LED should turn on. If not, check the orientation of the LED, or check the pin with a voltmeter. There should be 3.5v to 5v on it. | ||
| - | |||
| - | That's it. You're up and running. | ||
