USB controlled Bike Light
This project is under development. Here are some things I have found useful:
I am using a PIC18F14K50 processor and I bought the Low Pin Count USB Development Kit from Farnell, which includes the PICkit2 Programmer / debugger. The first thing I wanted to to was flash four the LEDs on port C, so I followed an online * PIC tutorial using assembly. I then converted the project to a C program and recorded the steps taken here:
- Install MPLAB IDE and the C18 compiler from the microchip website
- Connect the PICkit2 to the development board as shown in the photo
- Run MPLAB IDE and click on Project -> Project wizard...
- Click Next and select PIC18F14K50
- Click Next and select Microchip C18 Toolsuite
- Click Next and enter a location and filename for the project
- Click Next twice (without adding any files to the project) and click Finish
- Click on File -> New and enter the following code in the new document
#include <p18f14k50.h> #pragma config LVP = OFF #pragma config FOSC = XT void main(void) { TRISC = 0; PORTC = 0;
while(1) { int value, delay;
PORTC = value++;
while( delay-- ); } }
- Click on File -> Save As... and enter a .c filename for the new file
- Right click on the Source Files folder in the project window and select Add files...
- Find the file we just saved and select it
- Click on Project -> Build all
