batteries - Using capacitors as a battery back-up - Electrical ...
Apr 6, 2022 · 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.
How different are 8-bit microcontrollers from 32-bit …
Apr 17, 2014 · 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.

STM32 GPIO Speed - Electrical Engineering Stack Exchange
Feb 25, 2019 · Most any very fast CPU or MPU have bus or GPIO pin speeds that require 10 ohm to 27 ohm resistors in series at the endpoint of the trace to prevent ringing and adjacent trace cross talk.
What are the various files types in Actel (Microsemi) Libero?
Here's what Microsemi said so far. (I'll probably merge the specific files into Brian Drummond's answer and keep the directory information.)
What is bit banging - Electrical Engineering Stack Exchange
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 ...
What happens when a ceramic bypass or decoupling capacitor …
Mar 8, 2022 · 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 ...
battery charging - Do I need to fuse batteries in parallel ...
Aug 28, 2018 · 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.
Why do consumer ovens use thermostats instead of PID + PWM?
Mar 21, 2021 · I've added a big N/C relay in series to the heater/thermostat circuit of my kitchen oven (don't tell the warranty people, and I didn't tell my wife until she caught me using it one day). With nothing connected to it, it just looks and behaves like a normal domestic oven. It cooks fine, and has a sawtooth temperature swing of 10 to 15°C.
How to config Channel A/B of FTDI FT4232H to JTAG
Mar 31, 2024 · So the FT4232H does not know what you are planning to talk but gives you the option to go into the fancy-bit-bang mode by a command. If you use FTCJTAG.DLL to open the device handle, it will take care of this step. The EEPROM allows you to make the channels only visible for D2XX by changing the driver from VCP to D2XX.
