how can i use jtagice isp
I want to build JTAG ICE in system debuger
I read that jtag ice can reprogram flash ( write BREAK ins. to avr for stop avr at break point )
Can I use JTAG ICE INSTEAD OF STK200 programmer to full programing avr ?
I need simple code or algorithm to compression method on MCU

How can I do?
I need fastest method ( please !)
low pass filter uhf
You need a simple low pass filter with one or two varactor diode. When varactor capacitance is high, the filter will kill the UHF and the poor customers will not be able to see the p*orn movies...
Yes ...you right ,but this is not for p*orn movies.
I need low pass filter...

300 mhz bandpass filter circuit
sorry about my bad english
I want a circuit for no-pass UHF filter. for RF antenna T.V
It must allow to pass VHF-L and VHF-H with high quality and not allow to pass UHF
thank you for answer
I want to connect a MCU to standard external pc modem.
1-Is there any topic or link or similar project?
2- I think an external modem can detect busy line..... no answer ....... dialtone....and it can report it by rs232 com port to MCU.
is it true?
I want to know , if I want to multiplex 4 sevensegments, which refresh rate I must use for everyone? If I use 8 sevenseg. which refresh rate ?
( I think every 4ms for each one , is it true?)
any link for sample ?
