Down to Code

Shown below is a simple code sample for a Hello World project example. The code demonstartes how to configure the PIC and flash an LED.


                /* It's That Easy Series RADIX - PIC18F25K22 */

                    void ConfigureDevice()
                    {
                        // Peripherals you don’t need
                        ANSELA = 0x00;
                        ANSELB = 0x00;
                        ANSELC = 0x00;
                        
                        // Inputs and Outputs
                        TRISB = 0b11111110;
                        // Initial PIN Configuration
                        LATB.B0 = 0;
                        }
                    
                        Flash_LED()
                        {
                        LATB.B0 = LATB.B0^1;
                        Delay_MS(500);
                        }
                    
                        void WhatToDo()
                        {
                        Flash_LED();
                        }
                    
                        void main() {
                    
                        ConfigureDevice();
                    
                        while(1)
                        {
                            WhatToDo();
                        }
                    }

Why use the RADIX. . .

The RADIX utilizes one of Microchip's powerfull, energy efficient and extensbible devices. Prepopulated on the RADIX, it's a power up and play solution capable of running from a USB cable. The Device itself offers many itegrated peripherals namely: USART, I2C, SPI, PWM, CCP timers and so on. That's allot of techno jargon, but it equates to a compact purchase with many open doors for ongoing development; the device will allow you to grow your project to its full potential.
