[i=s]This post was last edited by abszy on 2014-7-3 19:18[/i] Presumably many of you have heard of or played with S3C2440. Now, what are the differences and improvements between 2416 and 2440? Please ...
The PCB made according to the schematic diagram can generate square waves normally with a frequency of 43KHz, but when simulating with Multisim, the frequency is abnormal and is several MHz. I don't k...
The specific phenomenon is that during simulation, Protues only prompts "simulation is not running in real time due to excessive CPU load" and then stops running (observed by reversing PB^9 in the pro...
