I recently got a pikit 2, its the 1st time that im using push button switches.
im using 4 pushbuttons.
All i want for now is:
when i power the circuit The LCD displays "infrared liquid level detector", so the lcd code and initialising is working. BUT
when i press ENTER/Settings button....i...
sharp gp2
This is for the PIC 18F1320 BUT i want to modify this code to suit the PIC16f690. I am trying but not sure about a few things. I attached a word document with the relevent datasheets from the 18F and 16F.
void main()
{
// setup the PIC 18F1320
OSCCON = 0x72; // internal...
how to enter in switch
I want to create a user interface using C programming for a pic microcontroller-see attached picture.
It will have 3 pushbutton switches. It will allow the user to enter a 2 digit value:
1.enter/settings switch
2.increase digit from 0 to 9
3.decrease digit from 9 to...

i want to determine the distance from the time interval between pulses.
Just imagine you dropping a stone into a deep hole and waiting for the sound of the stone hitting the floor.

im, using a TSOP48,
output is active low, digital output
Added after 1 minutes:
What do you guys think about this method for calculating the distance?
Any simpler method?im using a timer to determine the interval between transmitted and received signals

ambient light detector
/*generating 40KHz low duty cycle pulses which will drive an Infrared transmitter. When an object is
infront of the infrared transmitter then the receiver IC will detect the object and an LED will GLOW.
i want the project to be immune to ambient light such as a desk...

generating 40Khz pulses with a microcontroller
Software based ambient light detection.
the sensor is controlled by a microcontroller to generate the low duty cycle pulses, you can benefit from the High and Low pulses to be able to detect any false...
pic16f690 programming c
im designing an infrared proximity detector for my project. I am a new user to the pic microcontroller. I am programming in C.
i have an infrared receiver IC TSOP48.
the output of the infrared ic is active low. and can be directly demodulated by a microcontroller...
the design must:
indicate the liquid level in a container using infrared.
EG. if the container has 10cm height of liquid in it, THEN the design must display the level
" 10cm level"

detect infrared level in sunlight
1) any1 recommends the use of a circular barrier surrounding the led(transmitter side) for noise immunity?
Added after 1 minutes:
circular black plastic tube.
2) what functions/modules can the synchronous detector be broken down into?
oil drop on infrared sensor
The CTRL input in the figure, stands for Control, and this pin should be connected to the source of the low duty cycle pulses discussed above, whether it is a microcontroller or an LM555 timer that generates the pulses.
Somebody please tell me if im visualizing the...

thanx so much for the feedback all!!!mwah...
"Distance (level) alarming thresold can be set (tunned) if the LED current limit resistor (in trasmitter side) is replaced by a variable one."
the 2nd posted cct uses a variable resistor in the transmitter side.
