Xilinx Virtual Download Cable using Raspberry Pi

based on this project below…( Thanks this great project )
https://github.com/tmbinc/xvcd

just replacement following function calls…

======== gipo.c ========
#include

#define GPIO_TDI 3 /// JTAG TDI pin
#define GPIO_TDO 12   /// JTAG TDO pin
#define GPIO_TCK 13   /// JTAG TCK pin
#define GPIO_TMS 14   /// JTAG TMS pin

void gpio_init(void)
{
if (wiringPiSetup() == -1)
return;
gpio_output(GPIO_TDI, 1);
gpio_output(GPIO_TMS, 1);
gpio_output(GPIO_TCK, 1);
gpio_output(GPIO_TDO, 0);
}

void gpio_close(void)
{
}
================

======== gipo_inline.h ========
static inline void gpio_output(int i, int dir)
{
if (dir)
pinMode (i, OUTPUT);
else
pinMode (i, INPUT);
}

static inline void gpio_set(int i, int val)
{
if (!val)
digitalWrite (i, 0) ; // Off
else
digitalWrite (i, 1) ; // On

}

static inline int gpio_get(int i)
{
return (digitalRead( i )!=0);
}
================

Tested with NetBeans IDE 8.1 + Raspberry Pi 1 & 2 + Xilinx XC3S400AN

NETBEANS 開發 RASPBERRY PI APP

使用 NETBEANS 開發 RASPBERRY PI APP
非常方便，可遠端開發、執行偵錯

請參考此篇…
http://www.raspberry-projects.com/pi/programming-in-c/compilers-and-ides/netbeans-windows/installing-netbeans-for-c-remote-development-on-a-raspberry-pi

主要需增加一個遠端 HOST 的設定

若有使用 WIRING PI 等 I/O 底層服務，則需以 ROOT 身份進行遠端操作
可參考此篇…
http://www.raspberry-projects.com/pi/programming-in-c/compilers-and-ides/netbeans-windows/creating-a-new-project

主要為了打開 ROOT 帳戶
sudo passwd root
sudo nano /etc/ssh/sshd_config
PermitRootLogin and change it to yes (the default "without-password" won't work – change it to "yes"
存檔後 reboot
