<div dir="ltr">Hi, <div><br></div><div>Excellent talk tonight, Jan. Pure Excellent!<br></div><div><br></div><div style>I just want to follow up on my question, which is on the micro controller programming side. Could you give us a brief idea what micro controller programming is all about please, Jan? </div>
<div style><br></div><div style>I.e., </div><div style><br></div><div style>- to read the voltage, or capacity, or RPM, can you just do a USB read, or you have to do some programming, e.g., to have the MC to prepare the data then put the data at dual band usb ram before reading? Same question goes for the DAC converter as well. How ready-to-use it is? Briefly explanation would be good enough for me. </div>
<div style>- Beside programming MC to provide the above read/write, what other typical things you can program the MC to do? I guess you can use complicated logic when programming it, right? </div><div style>- Do you think the following would be a typical real-life usage of the MCs? You write to MC a certain bytes, representing some certain commands/instructions; MC correctly interprets those instructions and "calls" the "predefined procedures" to carry out the tasks. Then you send out the instruction for reading back the data, and then read them back, right? </div>
<div style>- Since MC have no cache, then I guess to get the correct RPM value, you have to pull the data from its USB as fast as possible, If so, it still seems a problem to me that Linux is not a real time OS. I've leaned that MC can get those readings at pretty predictable interval, but at the end of the day, wouldn't how fast/predictable the USB host can read them back still be the problem? </div>
<div style><br></div><div style>Last questions, please explain very briefly, how can the USB host know that there are still unused USB bandwidths? </div><div style><br></div><div style>Thanks again for the excellent talk. </div>
