Hello Mr.Fvm,
The delay i mean is shown as example below,
int main(void)
{
//Set the duty cycle to 50% of PWM at this program line
//Then delay for certain time after set the duty cycle to 50%
//Then proceed to next instruction line
}
So, the delay i mean is the delay after the setting the...
Hello,
I am facing a question regarding using PWM to control the speed of the motor. I am using DSPIC30F4013 from microchip to generate the PWM signal. The signal is fed to L293D, which is the popular H-brigde motor driver.
My question is, i want to change the speed of the motor accroding to...
hello guys,
I am a beginner to the c programming in micro controller, so if the question sound stupid please forgive me.
I want to assign the special name to each bit for SFR. For example, PORTBbits.RB0 represent the bit 0 in port B register. I want to give name to PORTbits.RB0 like...
Hi,
I am new to PIC18f452. Last night, i read the datasheet of the PIC18f452 and come across through the CCP mode of PIC18f452. In the datasheet, it state the CCP1 has special trigger event and CCP2 don't have special trigger event. What does the term "special trigger" event mean?
I want to...
Re: about Ultrasonic sensor
I saw a polarized SRF04 ultrasonic ranger finder. I am confused with the term "polarized". What does it meaning? This sensor is polarized due to its circuit design or due to special transducer?
Re: about Ultrasonic sensor
thank for replying, nice Mr.FvM
I have another question. There is a circuit modified from SRF04 ultrasonic range finder. They modified the circuit by their own for their own purpose of the project. They are using the aluminium housing transducer from the SRF04. Can...
about Ultrasonic sensor
Hi guys,
I have a question regarding component of SRF04 ultrasonic module. The company daventech manufactured this kind of ultrasonic range finder. My question is regarding the tranducer that it used. I want to ask is it all the ultrasonic range finder manufacturer like...
Hi,
I am working on a project related to ultrasonic transmitter. I get the PWM signal from PIC18f452 to ultrasonic sensor. The PWM signal can get 40kHz frequency but the voltage is from 0 to 5V only. My question how to make the PWM signal become peak to peak voltage from -10 V to 10 V?
My...
Re: PIC18 and webcam
hai,saeed_pk, i don't understand ur method mentioned in the quote above. Can u explain futher more?
I restate my question more clearly, Actually i want to use the PIC to control PC and webcam. The pic will communicate the data with PC. The PIC will control the rotation of...
PIC18 and webcam
good morning,
I am currently thinking of construct a mobile robot equiped with webcam. The webcam is connected to PC through wireless connection. The mobile robot contain PIC18 microcontroller. I want to use the webcam to recognize some stactic target.
The problem is can i...
Thank for replying.
so basically, the schematic i post in PDF file above is not suitable for my purpose. And i don't understand the zero crossing and crosstalk you mentioned in your post.
I also not understand the senstence in the quate below. Can you explain futher?
.
I found another...
hello....nobody reply?
Please, provide me some assistance regarding this circuit.
Is the range of ultrasonic sensor that can sense is depend on the transmitter only or receiver only? How do i adjust the range distance that ultrasonic can sense ?Please provide me some explaination.
Beside. on...
hello everyone,
I am currently facing problem with building the the circuit for ultrasonic sensor. I am currently build a project for the following robot car follow leading robot car. To keep the safe distance between of following robot car and leading robot car, i want to use the ultrasonic...
mplab pic18f452 bootloader
hello guy,
I am undergraduate and want to learn about the bootloader of the PIC18f452. I am the beginner to the PIC world, not just PIC 18f452, so my question my be silly.
1) After do some google search, i found that there is many software used for...
