Can anyone help me make a MCU acknowledgment

Acknowledgment? Haven't heard of it!

I've never heard of any confessions.

I. 2Random, Read-only, 3, Special Function Register, 21 (uncertain) 3Address, Data, Control.

4.External interrupt 0, external interrupt 1, timer 0, timer 1, serial interrupt.

II, g, e

III. 1Timing: The counter is accumulated according to the system clock, and the working mode is overloaded according to the configuration;

Counting: The counter accumulates Suizhi Prefecture based on external input signals;

A timer is used for timing; A counter is used to measure the number of changes in an external signal.

The sampled value is a discrete fixed value, and the input is a continuously varying analog value, and the continuous variation signal is represented by a fixed discrete value, which will inevitably produce an error, which is called a quantization error.

Fourth, 40h, 10h, 30h, fifth, no.

6. org 0000h

ljmp main

main:mov r1, #00h

mov r0, #40h

mov dph, #20h

loop:mov dpl, r1

mov a, @dtpr

mov @r0, a

inc r0

inc r1

cjne r1, 50, loop

end It's really easy to earn a few points from you...

……Ants on a hot pan, flies without heads ......

The program has already written that this is for the AD9850 to write the configuration word, don't you go to ADI's ** to find the AD9850 specification and application manual to take a good look?

It has been clearly written in the note that 2 to the 32nd power minus 1 is equal to 4294967295, 4294967295 125000000 = . Calculate the control word with floating point first, which helps to improve accuracy. Of course, if your main control chip does not have a floating-point arithmetic unit, you can also use integers to scale up first, and then scale down back ...... after calculation

Does anyone still use compilation? Let's use C. What I learned in school, hey......

Hello! Then do you have the overall idea, have you selected the chip, and the circuit diagram can help you.

Pick up the projects you have done again, and then reduce the power consumption as much as possible, so that the system power consumption can run for more than one year on battery drive, and test it in harsh environments to ensure system stability.

Make a signal transmitter and receiver with a transmission distance of 100 meters or more.

Topic: Try a snack bar ordering system?

Do you want to do this yourself?。。。

MCU program in**? Nothing? Let's complete the task of asking questions.
