So I am trying to compile the example code for the MCP2517_click (Mikroe) example but its coming with error.
from what I could diagnose, it seem that I am missing some of the required libraries (even though I did download and install the package!)
If anyone would point me to or share the libraries required for this example code, if would be much appreciated!
Code: Select all
/*
Example for MCP2517FD Click
Date : Jun 2018.
Author : Nemanja Medakovic
Test configuration PIC :
MCU : P18F87K22
Dev. Board : EasyPIC PRO v7
PIC Compiler ver : v7.2.0.0
---
Description :
The application is composed of three sections :
- System Initialization - Initializes peripherals and pins.
- Application Initialization - Initializes SPI interface and performs the device configuration to work properly.
- Application Task - (code snippet) - Always checks is a new message in FIFO ready for receiving and when
is message ready, receives a message from the other device.
Also in this example we can send the desired message via CAN communication to the other device.
We can choose a message to be sent by sending the determined command to the UART.
In this example the command can be number from 1 to 5.
Additional Functions :
- char * _strcpy( char * _to, char * _from ) - String copy function.
