Hi all,
Need help to implement small app where two sides (PIC + ccrf2 each side) exchange data. For now, I am just trying to make a connection to ccrf2 and calibrate it but it's not going well. I am using UART for debugging, and software gets stuck in first do-while loop in manualCalibration() function, SPI_ReadExtended() never reads 0x41.
I am programming PICs on EasyPIC5 board, using MPLAB X IDE v3.30. Also, I am using cc112x_easy_link as reference guide.
Code:
#include <xc.h>
#include <math.h>
#include <stdint.h>#define _XTAL_FREQ 10000000
// CONFIG
#pragma config FOSC = XT // Oscillator Selection bits (RC oscillator)
#pragma config WDTE = OFF // Watchdog Timer Enable bit (WDT enabled)
#pragma config PWRTE = OFF // Power-up Timer Enable bit (PWRT disabled)
#pragma config CP = OFF // FLASH Program Memory Code Protection bits (Code protection off)
#pragma config BOREN = OFF // Brown-out Reset Enable bit (BOR disabled)
#pragma config LVP = OFF // Low Voltage In-Circuit Serial Programming Enable bit (RB3 is digital I/O, HV on MCLR must be used for programming)
#pragma config CPD = OFF // Data EE Memory Code Protection (Code Protection off)
#pragma config WRT = ON // FLASH Program Memory Write Enable (Unprotected program memory may be written to by EECON control)/******************************************************************************
