I wrote a high-pass filter program. Now I give a simulated signal, for example (temp=200.0*sin(2*pi*f*t1)) where f represents the frequency of the given signal, t1=t1+1.0/18000. After sampling this si...
I am designing a board that needs this 80-pin chip. I don't know if it is available. I am afraid that the board will not have the chip.Could you please ask the agent if it is available and how much it...
If the word "mobile phone" is not added to the title, I believe many people will not know what this is, right? IUNI means I am unique. Last November, IUNI announced that they would soon operate the mo...

Thank you very much, I feel that it is something within my ability, but I just can't figure it out. I have been working on it for a long time. Let me introduce my situation below: (fpga has a local cl...
Atmega128 enters power-down mode:
MCUCR=0x30;_SLEEP();
All IOs have been placed in a state of no input or output current.But the measured current is still 2.5mA (not the maximum 40uA as stated by DS),...
