How to write the single chip microcomputer control brush ESC program. 100

Be. Brushed motors.

Right? Quite simply, you can control one with PWM pulse width.

uln2003

That's it. If you don't have ULN2003, you can find a transistor and build a circuit yourself. The current output of the IO port of the microcontroller is too small, and it is not possible.

Direct control. Motor's.

Is it a brushed motor? Quite simply, you can control one ULN2003 with PWM pulse width and you're good to go. If you don't have ULN2003, you can find a transistor and build a circuit yourself. The output current of the IO port of the single-chip microcomputer is too small to directly control the motor.

Isn't the ESC also a servo, PWM pulse drive is OK, interrupt once with timer 100us, and clear 0 for 200 times (20ms).

And output high, 10 to 20 flips output low corresponding to a pulse width of 1 to 2ms

Look what single-chip microcomputer you use,There are some single-chip microcomputers with PWM function,You can enable it directly,But 51 single-chip microcomputers don't seem to have any,But you can also use a timer to do it,The accuracy is also very high,You can add me if you need to,I have some information here,You can communicate about it,Thank you。

#include

unsigned char pwm0=0x80,pwm1=0x80,pwm2=0x80;Percentage of PWM.

void initt0(void)

void main(void)

void timer0(void) interrupt 1 timer for pwm.

The driver is mainly circuit driven, and the program only provides PWM parameters according to the step saw angle.

I use Freescale chips, output four PWM waves, can be well controlled, if needed, leave a mailbox.

The driving capacity of the single-chip microcomputer is very small, and the driving current is only a few tens of milliamperes, so if you want to drive the motor, you must also add a driving circuit, the simplest is to make an H-bridge circuit with two transistors, or you can use the driver chip to connect to the H-bridge circuit, such as BTN7970 or BTN7970 and other driver chips, and the corresponding pins of the triode or the corresponding pin of the drive chip can control the forward and reverse rotation of the motor with the single-chip microcomputer.

The driving capacity of the single-chip microcomputer port is not enough. A driver needs to be added.

I don't understand the question, do you want to do the ESC or control the ESC, I think the output of the ESC is the PWM wave.

I guess you are not doing a model airplane, what you mean by the period of 20ms refers to the control signal of high level 0--2ms and period 20ms.
