发帖数: 220 | 1 我做mouse NFAt c3的IP, 预测的分子量应该是115Kd， 我IP下来大概100Kd有带，
但是input 里面分子量变大了快到150Kd，（略小于100也有浅带，但不是IP那条）
为什么会这样呢？
有人说可能是sumoylation， 可是为啥IP下来这修饰就没了呢？
谢谢。 |

发帖数: 121 | 2 我也碰到类似的情况
我的是IP下来的，比input稍微高一点
一个如果60，一个可能就60－65KD
一开始以为是磷酸化，加了ppase，还在原来位置
现在也不知道，那个到底是非特异性的
还是什么修饰 |

发帖数: 26 | 9 电路用small signal analysis分析完，然后我给出simulation results，但是input是
square wave，不是sin wave。老板说不合适，要改成sin wave，small signal
analysis指的是sin wave信号，不是square wave信号。理论上好像是这么回事，不过
这年头好像sinwave信号很少见呀。我分别跑了电路对sinwave和square wave的
frequency response，是有一点不同，但是大体上是一致的。大家什么看法 |

发帖数: 840 | 17 板子上要用到2个micro-controller
两个mocro-controller通过SPI bus communicate
如果我给这两个micro controller各自用一个12MHz的crytal作为clock input，那么
power up板子的时候会有问题么？
多谢！ |
|
T******T
发帖数: 3066 | 18 The two micro-controllers does not have to be completely synchronous to each
other.
The SPI master/slave controllers and their associated buffer/fifio on either
device will tolerate much slower rate spi traffic completely ignorant of
the fact that the two clock input source are not aligned.
Now, if you are pulling I/Os from one device straight into the other device
without synchronization, and the circuit requires alignment then that won't
work. Otherwise, you should be ok.

发帖数: 49 | 19 它是用input capture中断来捕获Sensor的输入信号。
因为Sensor是一个霍尔传感器，用来检测一个运动齿轮的速度，但这个齿轮的转速是在
一定范围内可变，可调（用户根据应用来调整的）。
最慢可以几HZ， 最快1000 HZ。所以，这个输入中断发生的频率也就是几HZ, 1000HZ之
间。
但是RTOS还有18-19个任务，同时该程序还有另外10来个中断。
我担心会不会导致有的任务长时间内得不到运行时间，或者干脆给饿死呢？ |

发帖数: 24265 | 20 input捕获中断，其他还有timer ad等中断，其实用中断效率最高
俺认为最高1000hz输入中断对于40MhzMCU应该没啥问题 |

Yes, input method is one thing. For example, I can only use PinYin for Traditi
onal Chinese, it's not availabel for Simplified Chinese. And if the Pinyin is
longer than 4 letters, for example, ming, I'll have to type in min and then cl
ick through until the one I need appear. If I type "ming", the character panel
would dissaper. Very weird. Does this happen to PC at all?
And also, many characters are missing, even the very common ones.
Would you be able to type Chinese with your email account? |
