You need to remember that the servo will be looking a pulse every 20ms to hold the position.
I do not program in C but, Your code, if I am reading it correctly, would move it quickly to the end point and then go into an endless loop without supplying a pulse to the servo on a regular basis.
You need a second delay, you are switching off the the leds, waiting 500ms the switching then on, then straight off again, you want a delay after switching them on.
void main()
{
pic_init();
while(1)
{
led0=0;
led1=0;
__delay_ms(500);
led0=1;
led1=1;
__delay_ms(500);
}
}
The poisiton of the servo is controlled by the pulse width, the most common of these is 1.5ms centre position. The servo needs a constant stream of these pulses to hold its position approx every 20ms. When you reset the system you need to start feeding the pulse width, that is you required...
As stated earlier there seems to be some confusion, the servo you are looking at is a standard RC type unit, the difference bewteen digital and analog servos of this type is to do with the internals of the servo not how you would control it. All of these servo are contoled by PPM, (pulse...
A software interupt is drive by a predifined period of time usual a counter, that overflows or reaches zero, that triggers the interrupt routine, where as a hardware interrupt is from an external force for example a switch. HTH
This is the schematic for easypic7 which has the board cirucuit built in easypic_v7_schematic_v103.pdf
and this is another example I found 079-touchclock.html
Found this old thread about adding on to Proteus https://www.edaboard.com/threads/191364/
What you need to rememer is the available current on the output, also by not directly driving a device directly, you are providing a degree of protection for the MCU.
What you need to remember is
A servo requires a cycle of about 20ms
The position of the arm (on most servos) is a pulse between 1ms & 2ms, wth 1.5ms being the centre.
Therefore as an example to move the arm to an extreme
High pulse 2ms low for 18ms- making the 20ms cycle. This needs to be...
Re: Types of Servo motor
If you want to control the direction of your motor you need to consider using a H-Bridge, and then possibly some sensors to limit the movement.
The question is do you mean to use the same databus for all LCD's, in which case, I would assume you need to
ensure the lcd's are in read mode Ie ground the R/W pin
Use a common micro pin for R/S
use a different micro pin for each LCD's EN pin
I have not tried this but can not see why it...
Are you sure the pins from the pickit are connected correctly, I once connected mine with the pins reversed and after that it would not identify the chip, I must have blown the chip.
