Sampling is used to take sample of analog varying quantity. like sine wave..
To get the approximated shape. Two times sampling is required then that of freq of wave to be sampled.
As the Nyqueist 3rd rule.
There are many sampling algorithm. two point, 3 point, algorith, delta mehtod.

Hi,
You need to select the source files. You can go through the available examples in the software. you need to select the hex file for the your code.
and you need to install the driver in Keil u vision. if you are using it with KEIL to compile it.
you need to select the simulator/ debugger...
Hi Khan,
You can use serial programmer for avr atmega32. it will very easy to design and if you don't want to design it then you can get it @very cheap rate in market also. Don't use universal programmer as it support multiple hardware you can face this issue.
even you can search programming...
Hi Dear,
Your question is valid. I would like clear your doubt.
Protocol : Protocol is rules and regulation or grammar to implement something. protocol is actual format for transmission and reception.
I would like to give one example to you. English is language. grammar is protocol, which...
Re: can vs rs485
It is not like that RS232, RS422, RS 485 is still being used in embedded system/products or microcontroller based system. It is also used for downloading the software as a media to download the software.
but yes still ethernet is prefferd one in higher end application and...
Re: Booting squence!
Bootloader
The first program which runs on any Android system is the bootloader. Technically, the bootloader is outside the realm of Android itself, and is used to do very low-level system initialization, before loading the Linux kernel. The kernel then does the bulk of...
I2C:
start condition: SDA Low to High CLK High constant:
stop condition: SDA High to Low CLK High Constant
data transfer:
1)
Start
2)
Slave address:
Generally consist of 7 bit address and R/W bit
In some IC need to set 4 bit constant 3 pins A0,A1,A2 (as jumper setting) and R/W bit.
3)...
I have not gone through you code in much details,as it was in assembly.... but still i m trying to do best whatever i have experience....
I am thinking this as a syncronizing issue....
As u said u are getting more delay somewhere after one cycle... mean timing generation is not proper...
It is common mistake to forgot to write the break in switch statement....
if you forgot to write break statement then It will continue to go on executing the next statement of of other case also...
So it will cause the problem....

How can i do that please help me out in this...
Thanks...

Re: SPI and I2C
Main topic to discuss the difference is
1) speed is difference
in case of i2c is 100/400kbps in 7 bit mode max 400kbps
in case of spi speed is upto 1mbps
2)Connection wise: i2c require less pin then spi
as spi require slave select for individual device...
3)it is better to use...
