projects based on photodiod
Thank you for this project. It's very interresting and I want to test it this week.
For moment I only have one question:
Why it talks about 1 photo interrupter for IRLED1 (Jaycar Cat. Z-1901 or equivalent) in the document and we saw a single IRLED picture on the...
Thank you,
but there is a solution for log() ? It's possible to use another thing than the log() function ? Or there is a solution to calculate the formula in the interruption routine by part ? Like humm, to do it "in same time" instead my other function ?
Thank you,
humm as well, I forgot to specify somethings:
- I use a PIC16F877A.
- It's really three 7-Segment led (not a LCD) that I use. I need to multiplex them.

Hello all,
I have a problem with my display. The problem is when I need to do some "long" mathematics calculus (after a ADC conversion), my display "flash" less than one second, but it's visible for human eyes...
I program in C. I think to use interrupt for my display but I don't know exactly...
As like other said, it depends on what you are working. If you need some features of PIC16F877 but you don't need a lot of port, I suggest you to use the PIC16F88.
Hello,
I want to use external push button to setup a variable in my microcontroller. I have two button: up and down. I use a debounce algorithm to assure that when I push the button one time only, the variable is incremented one time only...
But the problem for now is when I keep the button...
Re: RC Oscillator
Thank you very much.
I need to generate a delay about 10 seconds. But I don't need precision... But of course I don't want that the delay of about 10 seconds become 20 seconds... And I have to check the state of some push button with an interruption timer (check about 50...
RC Oscillator
I read on the net that a RC Oscillator can have variations of 5% to 50% of nominal output frequency.
It's true or it happens only if temperature changes of something like that ?
And, if the RC Oscillator can change about 50% of the supposed frequency, it's not a good choice if...
Because the table will be stored in RAM memory and I have only 128 bytes for RAM...

I tried all solution here and it's down the memory code space by half. Thank you very much everybody!
Hello,
I made this function maybe rapidly, but I don't know if it's possible to optimise it. Because it takes a lot of program memory data... (like 200 bytes).
It's for a PIC16Fxxx...
I think it's the basic form for this function. The using of this function is like vAffichage('7')...
