Thank you for having you +EEWORLD
Thank you eeworld for your company over the past year. It is great to have eeworld accompany me along the way. We have gained a lot of knowledge, broadened our horizo...
How should I interpret the circuit here? The gate and drain are shorted together. Since the I/O port of the microcontroller can only withstand 0 to 5 V, the output signal needs to be pulled to12 V so ...
I use a brushless sensorless motor board. The motor starts to rotate fine at first, but after accelerating to a certain degree, the motor vibrates violently and the speed cannot be increased. What is ...
In 430, one clock cycle = the inverse of the MCLK crystal oscillator. If MCLK is 8M, then one clock cycle is 1/8us;one machine cycle = one clock cycle, that is, each action of 430 can complete a basic...
As shown in the figure below, the terminal block is a double-layer pluggable terminal block
What does the number of positions in the red box in the picture mean?
It looks like there are 20 interfaces ...
Do I really need that technology? Should I buy it now? If I don't buy it, will I be at a disadvantage? Will I be eliminated because of making the wrong decision? Even if we don't want to be the f...[Details]
