Hi all. After following Selsinorks' tutorials on getting Debian working on the riotboard and then getting the Gnome environment up and running with the tutorial here:
Debian on RIoTboard - After basic install, adding a GUI Desktop and other usefull stuff
I have successfully installed Codeblocks working with C/C++.
Codeblocks installed easily : sudo apt-get install codeblocks.
After this I installed g++ (as codeblocks uses the g++ compiler to build..)
It compiles no problem and after following the post on GPIOs:
I changed this code here:
#include <unistd.h>
#include <string.h>
#include <stdio.h>
#include <fcntl.h>
class LinuxFile
{
private:
int m_Handle;
public:
LinuxFile(const char *pFile, int flags = O_RDWR)
{
m_Handle = open(pFile, flags);
}
~LinuxFile()
{
if (m_Handle != -1)
close(m_Handle);
}
size_t Write(const void *pBuffer, size_t size)
{
return write(m_Handle, pBuffer, size);
}
size_t Read(void *pBuffer, size_t size)
{
return read(m_Handle, pBuffer, size);
}
size_t Write(const char *pText)
{
return Write(pText, strlen(pText));
}
size_t Write(int number)
{
char szNum[32];
snprintf(szNum, sizeof(szNum), "%d", number);
return Write(szNum);
}
};
class LinuxGPIOExporter
{
protected:
int m_Number;
public:
LinuxGPIOExporter(int number)
: m_Number(number)
{
LinuxFile("/sys/class/gpio/export", O_WRONLY).Write(number);
}
~LinuxGPIOExporter()
{
LinuxFile("/sys/class/gpio/unexport",
O_WRONLY).Write(m_Number);
}
};
class LinuxGPIO : public LinuxGPIOExporter
{
public:
LinuxGPIO(int number)
: LinuxGPIOExporter(number)
{
}
void SetValue(bool value)
{
char szFN[128];
snprintf(szFN, sizeof(szFN),
"/sys/class/gpio/gpio%d/value", m_Number);
LinuxFile(szFN).Write(value ? "1" : "0");
}
void SetDirection(bool isOutput)
{
char szFN[128];
snprintf(szFN, sizeof(szFN),
"/sys/class/gpio/gpio%d/direction", m_Number);
LinuxFile(szFN).Write(isOutput ? "out" : "in");
}
};
int main(int argc, char *argv[])
{
LinuxGPIO gpio27(112); // here is the line I changed to reflect the gpio port (pin 5... as seen in the GPIO tutorial.)
gpio27.SetDirection(true);
bool on = true;
for (;;)
{
printf("Switching %s the LED...\n", on ? "on" : "off");
gpio27.SetValue(on);
on = !on;
sleep(1);
}
}
So we now have codeblocks and the flashing LED hello world type program working.
