On the other hand, there would be no way for PICs that speed to handle bit-bang communications in such a way that either device was allowed to transmit at any time it saw fit (as opposed to having one device which could transmit when it saw fit, and do whatever it liked when not transmitting, and one device which would have to spend most of its ...

2014年4月17日 · On the other hand, there are times when code will have to "big-bang" a lot of port manipulations, and the ability to do such things with a single instruction can prove quite valuable. On the flip side, 32-bit controllers are invariably designed to efficiently access many kinds of data structures which can be stored in memory.

2021年4月27日 · A big voltage potential, called Back EMF (ElectroMagnetic Force) will let the flowing current to continue to flow, by ionizing the nearby air to become sort of a electricity conductor (actually a poor conductor, or high resistance), and the otherwise no where to go current would happily go through.

2022年4月6日 · Fuses F1 and F2 are important. F1 protects the capacitor bank from destructive discharge (a.k.a. a big bang) should the DC link become shorted. F2 protects RLY1 and the associated wiring, since it wouldn't be rated for the full output current of 10-15A. The unsafe voltage on C2 is indicated in an energy-saving fashion by two indicators: X1 and X2.

2016年6月8日 · Wondering why you would choose to use smaller capacitors in parallel vs one bigger one. Here's an example: Multiple in Parallel Page 4: One larger C Is this a component size and track width cho...

2014年7月5日 · Normally the band that's over the end cap is the right-hand one, but that top row looks pretty ambiguous. The bottom ones are 220 ohms 1%, the top ones look like 220K 1%.

2022年3月8日 · Too much voltage can cause the dielectric (insulating) layers to break through and become short circuits. Too much voltage can also cause the capacitor to flex, resulting in a stress crack. Then you get the same result as above. The capacitor becomes more like a resistor, or shorts out entirely - bang or burn. Neither failure mode is usually a ...

2018年8月28日 · If you have never seen one of the big T-series 400amp fuses go bang! you have likely saved pair of underwear. Fuses blow by melting metal, producing liquid metal which can be ejected to land on some other connections causing another fuse to blow.

2018年12月16日 · Stack Exchange Network. Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.

2014年11月25日 · Develop in a big sandbox, and cut down later. The time you will save will more than cover the extra $4 you spend per microcontroller to develop on. This works for more than hobby-level stuff - and in fact is even more important. Picture 12 people waiting around for a shift to a larger controller to happen instead of one!! \$\endgroup\$ –
