Is there any equation for calculating SNR from LQI? what is the relation between SNR and LQI? If it can give the rough estimation then how can we get proper value of SNR?
Hello Everyone!
I am using RF transceiver of atmel and it gives me some reading of RSSI and LQI in its register.
I need to display signal to noise ratio of RF signal, but there is not direct register for that.
How can I get signal to noise ratio?
can LQI gives measure of SNR? or what is the...
Hello,
I want to make a boot loader code for avr, which can update firmware over the air. Now I am able to write application area using some fixed data. I have a hex file of the new firmware to be updated. how to convert that hex file to raw data so that I can update the application are using...
I am using atxmega256a3bu microcontroller for my project, I want to make a program architecture like I have compiled and programmed the code and now only some APIs can be changed and reprogrammed into the board other portion of flash should not be changed and newly compiled APIs can work with...
Hi all,
I am using CS5490 chip for metering of one street light.
I am trying to calibrate it but it does not working.
Have anyone used this chip here? Can anyone explain what exactly the chip does in its calibration?

hi all,
I got the answer
here it is:
Object files are what the linker uses to build complete executables (or libraries).
You can usually have your compiler output an executable "directly", the syntax will depend on the compiler. For instance with GCC:
gcc foo.c bar.c ...
will produce an...
Hi all,
I want to know that from where does the execution of program starts?
is it from 0x00 address?
then how main function goes to 0x00 address?

hi all,
when we compile a code it generates object file and from those object files executable files are generated in linking process.
why we need object file?
what is the use of object file?
cant it be possible that executable file is generated directly?
after all we are using executable file...
hi Dora,
Its not working means, there is no display on LCD.
I did not have error in code.
the driver chip of LCD MTF0280QN-18 is HX8347D, I found it on site **broken link removed**
I tried to read driver ID from LCD it is not receiving 47 as per datasheet.
I observed datalines in signal tap...
hi,
I have already searched it
I have tried below code but its not working:
// EXIT IDLE mode Setting
Set_LCD_8B_REG(0x18,0x36); //I/P_RADJ,N/P_RADJ, Normal mode 75HZ
Set_LCD_8B_REG(0x2F,0x11); //Normal mode line inversion 11 or frame inversion 00
//Set_LCD_8B_REG(0x01,0x00)...
I asked the manufacturer of LCD and as per their suggestion they told me that LCD is configured as 8-bit parallel by them.
now I tried the code to read the driver ID of LCD and as per HX8347-D datasheet it should be read as 0x47, but I am getting 0x00.
what may be the problem? can it be a...
I am using 2.8 inch LCD mtf0280qn with NIOS II processor.
the LCD uses HX8347D driver IC,
datasheet of this driver IC tells that it can be configure as 8 bit parallel or 16 bit parallel interface or many other by connecting pins IM0, IM1, IM2, and IM3 to VCC or ground,
but I have no any...
