[AVR club] Problem in reading analog Data from more than one Channel / Bootloader - Neena Sharma - Apr 1 9:26:43 2009

Hi
=A0
Is this question about reading analog data or bootloader.?
=A0
As for Analog channel, you must specify more details like what are the inpu=
ts. I have been using analog inputs to read various inputs but have never f=
aced this problem.=A0The Atmel datasheet gives many suggestions to reduce n=
oise on ADC channel.=A0

Hi Kundan
=A0
Bootloader is a program that helps to burn (write) program flash without an=
y programmer. Using mainly serial port.=A0I=A0was also in =A0need of =A0boo=
tloader for ATmega168 to work with AVRstudio(AVRprog does not support Atmeg=
a168). But after some searching I had no choice but to write my own. It is =
in Hex and does Flash, EEprom writing and verification etc. Work quite well=
and feels similar to AVR ISP downloading and uploading the program from AV=
Rstudio.
=A0
Basically it will be for PC controlled boards that will have feature of upg=
rading=A0firmware as and when needed.

Thanks
