Hi, I'm trying to build avr465 energy meter. I've done all the hardware section including the programming uC. I've got a great help from tpetar of this forum. I'm really grateful to him for his guidance.

Now I'm in trouble in understanding the display and output of micro controller. I want to use LCD display, in order to do that, i would use atmega8, i'll use the output of atmega88 as an input for atmega8. So i need to know what kind of output it will give and how i can use it as an input for the second uC. If any one can discuss on this part, I can finish the project.

If you have the hex file and a programmer, then use the programmer's software to make a project and then download it to the other MCU. Otherwise import the hex file from AVRStudio, set the fuse bits and download the code to the other MCU. I think there is a way to create a project in AVRStudio also, but I don't know how. But it doesn't matter, hex file and proper fusebits settings in AVRStudio will also do the job just fine!

Hope that helped.
 

I think you are trying to transfer the meter reading to another microcontroller Atmega8 for further processing if it is so, the whole thing has to be radically modified.
 

Thanks, MCU is burned with the .hex file before I'm posting this thread. I just want to understand what kind of output will give DPP and DPN pin, i thought i just can use those output as an input for atmega8 and make a display counter controlled by atmega8. So if you can guide me about the output, that will be a lot of help.
 

Table 7 on page 21 says:
Display pulse rate 100 imp/kWh See DPC calibration coefficient

So you must use a counter to accumulate usage. (100 pulses /h = 1kW)
This is the normal ouput from kWh and gas meters.
Please post picture and comments as you go along with this project.
 

Sory, can avr465 used for make digital power factor meter?
