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...
