create branch/ tag with tortoise SVN


Select the folder in your working copy which you want to copy
to a branch or tag, then select the command
TortoiseSVNBranch/Tag....


The default destination URL for the new branch
will be the source URL on which your working copy is based.
You will need to edit that URL to the new path for your branch/tag.
So instead of

    http://svn.xx.net/launchy/trunk


you might now use something like

    http://svn.xx.net/launchy/tags/Release_1.0.0

Working / Using EEPROM in WinAVR (AVRGCC)

Include the EEPROM API file (module which handles the interface on behalf of you)

#include



Define the Variable (where you want to put it)

#define BK_LIGHT_SETNG 0x00



write to the location

eeprom_write_byte((uint8_t*)BK_LIGHT_SETNG,0x7); //! read the settings



Reading the byte

xx = eeprom_read_byte((uint8_t*)BK_LIGHT_SETNG);



//=====================================================


you don't need to do anything from scratch, The work has already been done for you just use the interface header files.
AVR GCC Rocks... Free of cost... save lot of development time... and even the compiler is free, up to date with solid tools... (where you need to pay nearly $4000 + for tools like Keil)

Working / Using EEPROM in WinAVR (GCCAVR)

VR microcontrollers like many any other Harvard architecture MCU's are ships with some amount of EEPROM (Electronically Erasable Read-Only memory
) memory. This type of memory allows developers to store program
parameters, constants, menu strings etc. EEPROM memory is good that you
can read like one byte and store modified, while FLASH memory usually
is written in pages.

In this article I am going to show how to store data to EEPROM by defining a particular variable types.



For this we need to include eeprom.h header library from avr directory #include “avr/eeprom.h”.

Following is simple variable declaration using simple attribute word EEMEM:


#include “inttypes.h”

#include “avr/io.h”

#include “avr/iom8.h”

#include “avr/eeprom.h”


//store initial byte to eeprom

uint8_t EEMEM eeprombyte=0x10;

//store initial word to eeprom

uint16_t EEMEM eepromword=0x5555;

//store string to eeprom

uint8_t EEMEM eepromstring[5]={"Test\0"};

int main(void)

{

//RAM byte variable

uint8_t RAMbyte;

//RAM word variable

uint16_t RAMword;

//RAM array of bytes

uint8_t RAMstring[5];

//read byte from EEPROm and store to RAM

RAMbyte = eeprom_read_byte(&eeprombyte);

//read word from EEPROM and store to RAM

RAMword = eeprom_read_word(&eepromword);

//copy string fro mEEPROM to RAM

eeprom_read_block ((void *)&RAMstring, (const void *)&eepromstring,5);

return (0);

}


EEMEM
keyword indicates to compiler that variables has to be stored in EEPROM
memory and it creates separate .eep file which has to be written to
chip separately during AVR microcontrolling programming..

Lets see what I have got after compiling with AVR-GCC compiler the above example code:


Size after:

main.elf :

section size addr

.text 156 0

.data 0 8388704

.bss 0 8388704

.noinit 0 8388704

.eeprom 8 8454144

.stab 876 0

.stabstr 132 0

.debug_aranges 20 0

.debug_pubnames 74 0

.debug_info 486 0

.debug_abbrev 316 0

.debug_line 240 0

.debug_str 271 0

Total 2579


You can see compiler information about compiled code sizes. The bold line (.eeprom 8 8454144)
is indicating the size of occupied EEPROM memory in EEPROM memory
space. In this particular case we see that size is 8 bytes: one byte
variable, one word (two bytes) and five byte array – total 8bytes.


If you open .eep file located in project folder – you will see Hex File of EEPROM data:


:0800000054657374005555109E

:00000001FF


The
first line shows 8 byte data stored at address location 0. Second line
is the same for all hex files – it indicates end of file record.


Dont
forget, that .eep file has to be written to avr microcontroller
separately as writing compiled program doesn't write EEPROM data. If
you use PonyProg programmer this
can be done easily. Open .eep file by selecting File->Open Data
(EEPROM) File...and then select command: Command->Write Data
(EEPROM). The same can be done with tool-bar buttons.

Image

In
the PonyProg memory viewer there are both memory locations displayed:
Flash and EEPROM. You may noticed that EEPROM memory area has different
color than Flash. I hope this helps to some of you to get the picture
and can start working with AVR EEPROM memory.

Hello World with CUDA

Writing Hello World in CUDA is bit difficult ( CUDA does not support strings)

But the following is a vector addition program which may be a good starting point


Simple code to add two vectors.(Blue colour)

#include "stdio.h"

__global__ void add_arrays_gpu( float *in1, float *in2, float *out, int Ntot)
{
int idx=blockIdx.x*blockDim.x+threadIdx.x;
if ( idx
out[idx]=in1[idx]+in2[idx];
}

int main()
{
/* pointers to host memory */
float *a, *b, *c;
/* pointers to device memory */
float *a_d, *b_d, *c_d;
int N=18;
int i;

/* Allocate arrays a, b and c on host*/
a = (float*) malloc(N*sizeof(float));
b = (float*) malloc(N*sizeof(float));
c = (float*) malloc(N*sizeof(float));

/* Allocate arrays a_d, b_d and c_d on device*/
cudaMalloc ((void **) &a_d, sizeof(float)*N);
cudaMalloc ((void **) &b_d, sizeof(float)*N);
cudaMalloc ((void **) &c_d, sizeof(float)*N);

/* Initialize arrays a and b */
for (i=0; i
{
a[i]= (float) i;
b[i]=-(float) i;
}


/* Copy data from host memory to device memory */
cudaMemcpy(a_d, a, sizeof(float)*N, cudaMemcpyHostToDevice);
cudaMemcpy(b_d, b, sizeof(float)*N, cudaMemcpyHostToDevice);

/* Compute the execution configuration */
int block_size=8;
dim3 dimBlock(block_size);
dim3 dimGrid ( (N/dimBlock.x) + (!(N%dimBlock.x)?0:1) );

/* Add arrays a and b, store result in c */
add_arrays_gpu<<>>(a_d, b_d, c_d, N);

/* Copy data from deveice memory to host memory */
cudaMemcpy(c, c_d, sizeof(float)*N, cudaMemcpyDeviceToHost);

/* Print c */
for (i=0; i
printf(" c[%d]=%f\n",i,c[i]);

/* Free the memory */
free(a); free(b); free(c);
cudaFree(a_d); cudaFree(b_d);cudaFree(c_d)

}

===========================
Running the Code
===========================

Copy the code in a file add_vector.cu
Compile it with nvcc: nvcc -o add_vector add_vector.cu
Run it: ./add_vector

If you don't have a Cuda capable GPU, compile it in emulation mode:
nvcc -deviceemu -o add_vector_emu add_vector.cu
Run it: ./add_vector_emu
